As far as I know, if you plug in your Nexus5 (or any phone) into a power source with high amperage (>1A), your phone should utilize the amps it actually needs to charge at full speed (AC Charging).*
For example, if i plug my Nexus 5 into a 2.1A charger, it will charge just fine and draw only the required amps needed.*
Ive noticed my phone (rooted with faux) and my wifes (stock) and very finicky when it comes to the amps a charger uses. *It appears that if a charger is not exactly 1.0A or 1.2/1.3A, the phone charges as USB and not AC (no matter which USB cable I use). *Below is what I have found out, *with charge type/amp and how the phone sees it
Stock charger (1.2A) - AC
Anker 25W 5-Port Wall charger (1A Android port) - AC
Anker 25W 5-Port Wall charger (1A iPhone port) - USB (not sure why??)
Anker 25W 5-Port Wall charger (1.3A Galaxy Tab Port) - AC
Anker 25W 5-Port Wall charger (2.1A iPad ports) - USB
Anker E4 13000mah battery (2A) - USB
ANker E4 13000mah battery (1A) - AC
Anyone else experience this?

What you've observed here actually has nothing to do with the amperage of your ports and everything to do with how their data pins are wired. The N5 (and most other android devices) looks for the data +/- pins in the USB port to be shorted together, this is how it determines it's connected to a charger. Apple devices do this differently, they look for a specific combination of voltages to be present on the data +/- pins. When you connect your N5 to an Apple port, it ignores these voltages and just charges as if it were connected to a PC.
Now the fact that it sees the Galaxy Tab port as a charger is kind of interesting because the Tab uses yet another method for charger detection. It looks for resistors of a specific value connecting the data +/- pins to the power +/- pins. Cool that the N5 recognizes this configuration as well.
Anyway, this is why your Anker charger has ports dedicated to specific devices, each one is configured a little differently.
That would make sense, however, I would expect the same thing on my Nexus 4 but that doesn't happen. It charges as AC for every port
Sent from my Nexus 5 using Tapatalk
It could simply be that the N4 uses a different power control IC from the N5 (they almost certainly do). That and the software controlling the charging determine whether the phone enables AC charging from different ports or not.
I believe (I have not tried this) that some custom kernels have a setting that enables fast charging unconditionally, to draw as much current as the hardware allows.
Yeah I'm waiting for a kernel to support Fast charge, don't believe any do at the moment

the phone may revert to lower power usb charging if some condition isn't met... the phone is completely ignorant of the rated power of the wall wart. current is drawn, it depends on ohms.. so it has nothing to do with the "power output." what i mean is there is no situation where too many amps is going to trigger something in the phone, the phone controls the amps and is ignorant of the max the supply can give unless the phone actually exceeds that and detects a voltage drop, the supply can't force more amps without raising voltage to do so but that's just not how these devices work. so it's not because of the amps of the charger, it must be some other aspect.
what the phone can see is voltage. the state of the microusb "Id" pin (which will probably be open if you are using a data cable and not a specific dock to put it in desk mode or car mode, not that i think the n5 has those modes, but the Id pin is what tells the phone these things, as well as set them into download mode to flash them) and the state of the data pins. generally the data pins need to be shorted together to tell the phone to go into ac charging.
it's possible however that if the voltage is lower than 5v, the phone assumes there is voltage drop from too low a power rating on the supply and it's unable to supply the current. in this situation the phone may default to a lower current charging mode. some ac chargers may not go all the way to 5.0v they may put out as low as 4.45v... if the voltage is either low or unstable from the "high output" charger it may cause the phone to think it has exceeded the output rating of the supply when infact it's just getting unclean power. try it with an official tablet charger for a kindle or something and not a store bought anything..... some of the high output chargers just have substandard regulators and/or filtering.
there may also be more to this. usb 3.0 has a higher current rating than usb 2.0 if the phone can detect the type of port it's connected to, that may also determine the charge mode.. (in thoery anyway, no reason it can't work that way, but i can't say i know that it does on any current device)
It's getting pretty aggravating now that my Nexus 5 charges as USB when connected to my anker slim 2 1A external battery as well as my anker astro e4 1A port. No reason why it should do this

If you use a fast charging USB cable with the proper pins shorted you should get it to charge with in AC mode. I grabbed one from Amazon and it changed from DC to AC on the same charger.

So I've read an article that mentioned USB 3.0 Micro-B faster charging capabilities, does anyone know any validity to this?
I know it increases transfer speeds, but I was unaware if it actually charged faster too.
And if it's true, does anyone have any car charger recommendations to support this feature?
I saw this, let me know what your thoughts are: http://www.belkin.com/us/p/P-F8M864/
Why pay $30 when you can get the same (or ever better) results with a good usb 3.0 cable and a 2.1 or Anker's 4.8A usb car charger for less?
It's true that USB 3.0 allows for higher current but this only applies when you're connecting a USB3.0 device to a USB 3.0 host like a PC. A charger isn't a host device, they work by shorting data pins. So chargers don't follow USB specifications at all.
Your limitation here is voltage and amperage. Because chargers generally work by shorting the data pins your phone will draw as much power as it can handle and as long as there are no limitations on your charger. So it's not likely that you will be able to max out a 4.8amp charger, actually it's not likely you'll be able to max out a 2.1 amp charger either.
I find it interesting that the stock Samsung charger is NOT a USB3.0 charger. If you look at the USB port on the charger, it doesn't have the 3.0 pins...
USB 3.0 cable DOES come with some S5's

Some people seem to have not been given a USB 3.0 charger, but others have reported that one was included.
I was given a 3.0 cable with mine in the box. It is a white cable and is labeled "Samsung" on the plug.
FWIW, the new 3.0 plkug seems to hold more tightly than the micro-B 2.0 plugs in previous phones.

Then what's the best charger to get for DC plug that you would recommend? Just look for something with the highest amps?
Just the cord

I was only given the one cord. Also, I don't believe that I got a charging block.
Only received a USB 2 standard lead with mine.
USB 3.0 standart is meant for PCs/Macs/Devices. Original USB 2.0 port on PC would output only 0.5A. Default wall chargers would output 1A. Car chargers are different, but my 2A charger didnt charge my old phone any faster.
With USB 3.0, PCs should give out 2A (if Im correct) meaning u will charge 4x faster on USB 3.0 port.
With wallchargers its different. Cable itself doesnt have the limit (atleast not noticable one), meaning on 2A wall charger, and stock USB 2.0 cable, which comes with galaxy S5, you should charge with 2A.
Each device have power protection aswell, thats why older phones can use max to 1A to protect itself, while tablets needed 2A charger. I suspect galaxy S5 is made to charge with 2A aswell, aswell it holds up backward compability with 1A.

I got the white USB 3.0 cable with mine, and it definitely charges much faster than my s3 did even on a 2.1A charger.
I bought a USB 3.0 cable from ebay, it is a surprisingly fat cable, the same thickness as an ethernet cable. Couldn't believe how fast it charged compared to my S3.
http://www.ebay.co.uk/itm/321347128...eName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
I plug this into the wall charger to charge the S5 instead of the tiny thin cable that I had from an old phone. I haven't done any proper testing on this but the old small cable seemed to take about twice as long to charge the phone as using this cable does. I can go from 15% to full on this cable in probably a bit over an hour or so and it seemed to be taking at least double that with the other non-usb 3.0 cable.
Perhaps the other cable is providing less power as it is quite old but is still standard usb to micro usb so I guess it provides the same as any other and in theory should charge exactly the same when plugged into the wall socket adaptor as the usb3.0 cable does? The old black micro usb cable says 28AWG on it, the white one which came with the S5 (which I have not tried) says 30AWG on it and I read that lower AWG is better for charging which implies the white one will be even worse than the old black one. The USB3.0 doesnt show an AWG number on it.
The only problem with this usb 3.0 cable is it needs a damn hard pull to get it out, I would rather use the smaller one but not if it takes much longer to charge it.

USB3.0 on PC outputs only 0.9A.
From wiki:
For usb 3.0
"there is a Battery Charging Specification (Version 1.2 – December 2010), which increases the power handling capability to 1.5 A but does not allow concurrent data transmission.[20] The Battery Charging Specification requires that the physical ports themselves be capable of handling 5 A of current[citation needed] but the specification limits the maximum current drawn to 1.5 A."
For usb 3.1
"The USB 3.1 standard is backward compatible with USB 3.0 and USB 2.0. Using three power profiles of those defined in the USB Power Delivery Specification, it lets devices with larger energy demands request higher currents and supply voltages from compliant hosts – up to 2 A at 5 V (for a power consumption of up to 10 W)"
Now it is all very confusing because I read on techspot that "usb 3.0 superspeed" effectively has this increase, where wiki says there is no such thing and that this "superspeed" is 3.1 not 3.0.
None of them mention 0.9a. So it is as clear as mud. The official plain old usb 3.0 will only do 1.5a and thats if there is no data connection, and either usb 3.0 superspeed, or usb 3.1 will do 2a but I have no idea whether it is called usb 3.1 or "usb 3.0 superspeed" which would be ridiculous and confuse just about every consumer on the planet. I doubt it is called 3.1 because I have never heard 3.1 mentioned before on any device or cable, which leads me to think the extra charging in the newer revision is actuall the "usb 3.0 superspeed" which basically means nobody has a bluddy clue because most things will simply say usb 3.0. there, clear as mud.

Electrical
Signal 5 volt DC
Max. voltage 5.00±0.25 V (pre-3.0); 5.00+0.25-0.55 V (USB 3.0)
Max. current 0.5–0.9 A (general);

The thing is that when you plug your phone on your computer, you use data transmission, so you're limited to 0.9A
So we get 2a from wall socket regardless of which usb cable used. And when connected to pc we get 0.5a from usb 2 and 0.9 from usb 3?
How long should the 2800mah battery take to charge from 2a from the wall socket from 0 to 100%? I worked out 2 hours 20 mins but I probably did it wrong. I just tested mine from 50% to 100% on the wall socket and it took 1 hour 15mins which seems about right for my 2h 20 calculation, but I could have sworn I had charged this thing from about 15% to full in a bit over an hour before, but I may be going mad.

Hi all.
There has been a lot of confusion on the Type-C port on the Nexus devices, all of the different USB specs, how it all relates to charging using USB Type-C devices, and what kind of data speeds you can get from Type-C devices. I did a fair bit of fact finding, and thought I'd consolidate everything I learned into one topic. For now, this is kind of a "living document" in that I am constantly updating the OP to consolidate knowledge. I'm not going to post everything you could ever know about USB specs here, but have provided the links! I am going to try to keep it focused on items as they relate to the new Nexus phones. As always, if you find this helpful, I'd appreciate the thanks.
I feel the state of USB-C cables and charging devices has been fleshed out well enough, and as such, I'm no longer updating this thread.

Good news for consumers! Amazon bans non-compliant USB Type-C cables.

What rate will my Nexus charge at with other devices?
___________________________________
When you connect your Nexus to a host, the devices must negotiate which charging rates can be used.
Type C hosts can negotiate with Type C devices using a specific wire in the cable known as the Configuration Channel - aka, the CC wire.
If you are using a Type-A adaptor or cable, the cable must identify itself as a Legacy USB connection (Type-C being converted to Type-A) using a pull-up resistor on the CC wire, grounded to the vBus wire. This is because the CC pin does not exist on Type-A ports. The Nexus will see the resistor, know it is on a legacy port, and it will then perform power negotiation using the USB BC2.1 protocol on the USB 2.0 wires in the cable. If the host is not BC2.1 capable, it will draw default USB current. (See page 149, table 4-12 for order of precedence.)
USB Type-C ports and chargers will provide 5V at 3A (15W) - true fast charging.
USB Type-A ports and chargers using USB BC2.1 should provide a max of 5V at 1.5A (7.5W).
Standard USB 3.0 can provide 5V @ 0.9A (4.5W)
USB 2.0 defaults to 5V @ 0.5A (2.5W).
What this means is that when your phone negotiates power with the host (your charger or computer), whatever current level they mutually agree upon is what your phone will attempt to draw. If you connect to a USB 2.0 port on your computer, a very old port which does not support the BC 2.1 protocol, then the most you'll be drawing is 0.5A. If you connect to a dedicated charging device which supports BC 2.1, it should draw up to 1.5A. Charging rates depend on this negotiation. Out of specification cables do not allow this negotiation to occur correctly. This may lead to faster charging, but you also risk exceeding the capabilities of your charger which may be dangerous.
As you can see, there is a big difference between 15 watts for Type-C fast charging and 2.5 watts for USB 2. Furthermore, please be aware that the phone will pull less current as the battery charges. A Nexus at 80% battery will pull less current than a Nexus at 20% battery.
In any regard, consider USB Type A to be the weak link in charging your Nexus.

What charger and cable will work with my new Nexus, and will it support fast charging?
___________________________________
My suggestion would be to make the move to Type-C car and wall chargers. You will eliminate the chance of using out of specification Type-A cables, and ensure you are always fast charging. Type-C will soon be the de facto interface for USB, so why not future proof yourself now.
If you have to use Type-A adaptors and cables, understand that there will be limitations and concerns to be aware of. Out of specification cables being the primary issue, which is explained below. Further, your charging rates will be half (or less) than what Type-C is capable of.
Table 2-1 shows all supported power specs for Type-C charging. Please understand that Type-A ports/cables will only support up to the BC 2.1 charging level of 1.5A. If it goes beyond this, your cable may not be compliant with USB specifications.
Hi. I'm an engineer at Google who has worked on USB Type-C on the Pixel and Nexus projects.
The reason that the Google chargers and cables are capable of 5V 3A support is because not only the cables but the port on the other end is certified for the higher 3A ceiling. You will notice that the cable that came with your Nexus 5X or 6P has USB Type C on both ends.
This ensures that not only the cable, but the connectors and the charging circuitry on the other side of the cable can support 3A before the phone starts to charge.
When you have a legacy cable like this one, the connector on the other side is a USB Type-A connector, which can be plugged into any USB port built since 1997, for example your ancient Pentium II PC may have a USB port that this cable could be plugged into.
NONE of those USB Type-A ports are rated to support 3A, so many of the USB Type-A to Type-C cables available on Amazon that claim they are rated at 3A and configure the identifier resistor to tell the phone to charge at 3A are not in compliance and could do damage to your charger, hub, or PC if you try to charge at 3A.
When you have a legacy cable like this, 2.4A, which is negotiated over a BC1.2 protocol like CDP or DCP, is appropriate over the Type-A connector. Any cable that you buy that claims 3A support I would be extremely wary of plugging into any of your hubs, PCs, or dedicated chargers.
Click to expand...
Click to collapse
By the way, the maximum current of 1.5A is defined by the BC1.2 specification for CDP and DCP, but in practice, a range of other current values are possible using Apple's proprietary protocol or other protocols that bump up the defacto maximum current with a Type A connector on one end up to 2.4A, as long as the charger and the device both support that current limit.
However, keep in mind that there are 3 different termination possibilities. If you have the USB Type-C Specification 1.1, take a look at section 4.11.1, and at Table 4-13.
You'll notice that DFP Advertisement lists "Default USB Power" "1.5A @ 5V" and "3.0A @ 5V". It's important to read note 1. If you are making a legacy USB cable that has Type-C plug on one end, and a Type A plug on the other or a Type-B receptacle, you must use the "Default USB Power" termination, and NOT the "1.5A" one. Default USB power defers to BC 1.2 spec for current negotiation, so that such a cable that is attached to a basic 500mA SDP port should only draw 500mA, for example. Make sure to use a 56 kΩ pullup!

As referenced in the quote, Table 4-13:
What about QuickCharge 2.0/3.0 chargers!? My Nexus has a Qualcomm chip, isn't it compatible?
___________________________________
No. Google has stated that it is not implemented in the new Nexus devices.
QuickCharge works by increasing voltage and amperage to charge quickly. The USB Type-C standard only works this way in USB PD modes, otherwise voltage never varies from 5V. This means that QuickCharge 2.0/3.0 is completely different from USB Type-C charging methods.
But my 2.4A rated Type-A charger works, and my phone says it is Fast Charging. What's the deal?
___________________________________
Your Nexus may report as fast charging if the Type-A cable you use is not compliant with USB specs.
Threads on this forum have confirmed that the phone will pull 3A (or about 2990mA) from the stock charger. These results were verified using apps such as Ampere. When using 3rd party equipment (non-OEM cables and chargers), I would suggest using an application such as Ampere to ensure that you are not exceeding the maximum rating of the charger or cable. Doing so can be dangerous! It will also verify exactly how much current your phone is pulling to charge - information I've found helpful if for no other reason than to satisfy my own curiosity.
If you are unsure if your cable is compliant, you can test it using the methods found here: http://www.androidheadlines.com/201...usb-type-c-for-nexus-5x-6p-compatibility.html
So, how should you approach charging and connecting your Nexus to other devices?
___________________________________
The same way you would any other device - plug it into the best thing you have available.
For connecting to computers, use the best port you have available. Type-C to Type-C > USB 3.x to Type-C > USB 2 to Type-C.
For chargers, try to match OEM specs: 5 volts at 3 amps output using a Type C connector.
If you have to use an adapter (Type-A to Type-C), Make sure you use compliant cables!
What data connection speeds will I get on my Nexus using Type-C?
___________________________________
If you want to dig deep into this, look at the "USB Type-C Specification Release 1.1.pdf" doc from USB.org, it defines on page 19 the types of plugs and cables for Type-C, including the USB 2.0 Type-C port. Starting at page 57 it defines all of the wires/pins for the different cables. Comparing table 3-10 to 3-11, you can see that all of the SDP (shielded differential pair) signal pins/wires are missing in the USB 2.0 Type-C connections. These are your high speed data connection wires. The Vbus, Vconn, cc, GND wires are all still present to support Type-C power delivery.
So, in other words, there are USB 2.0 Type-C ports, and USB 3.0 ports. For devices which don't require up to 100 watts of power, or won't use up to 10GB/s transfer speeds, the USB-C 2.0 port may commonly be used. The Nexus 5X & 6P fall into this category. What connection speeds are you going to get with the Nexus? USB 2.0 speeds.

========================================
I wanted to put in this addition to the op. Thanks to @aaron_huber for putting this information up.
Aaron said:
A wire is a wire, but in this case the magic is in the charger, the device, AND THE CABLE. From the USB-C Wikipedia page:
Full-featured USB Type-C cables are active, electronically marked cables that contain a chip with an ID function based on the configuration data channel and vendor-defined messages (VDMs) from the USB Power Delivery 2.0 specification. USB Type-C devices also support power currents of 1.5 A and 3.0 A over the 5 V power bus in addition to baseline 900 mA; devices can either negotiate increased USB current through the configuration line, or they can support the full Power Delivery specification using both BMC-coded configuration line and legacy BFSK-coded VBUS line.
The 6P does not support the full PD spec per Google, but it does use the "configuration line" which is an extra wire in the USB-C cable hooked up to an extra pin in the phone/charger to talk to the charger and negotiate extra current. If you don't have a USB-C cable with the extra pins/wires plugged into a USB-C charger on the other end that also has the extra pins to do the negotiation, then the phone will fall back to a lower current because the spec requires it. If you plug it into a USB-A charger or use a USB-A to USB-C cable then all you get are four wires - the "configuration line" to do the negotiation doesn't exist.
========================================
* Type-C capabilities exceeds previous USB Type-A 3.1 / 2.0 specifications:
** 2 way power transfer
** Universal plug type (reversible plug)
** Much high transfer speeds (10GB/s)
** Much higher charging capabilities (Up to [email protected] = 100W via USB PD)
** Alternate data modes for devices (Display port / Audio)
Known Type-C capabilities for Nexus 5x & 6P:
+ USB 2.0 Data transfer speeds
+ Full fast charging through USB Type-C ports or specifically designed 5v/3a capable Type-C chargers only
- Not Qualcomm QuickCharge compatible (may draw more current for charging than a standard USB port though, see below)
- No HDMI out (It is not type-c alternate mode capable.)
- Not USB-PD capable

Are 3.1 Type C cables backward compatible with 2.0 type C devices? I ask because if they are wouldn't it make sense for people to buy USB 3.1 Type C cables for future proofing vs 2.0?
I am in the market for a long cable and am confused as to which of the cables below to chose.

USB type c is just the physical connector it has nothing to do with the usb 2.0 or 3.0 so you might as well by the fastest ones
What we do need to worry about is whether or not the cable itself supports charging at 3A 5v
Looking at the two, it appears that the Cable Matters product is a cable designed to connect a computer with Type-C port to a peripherals with USB 2.0 Type-C ports. (Like the Nexus 6p.) The maximum data speeds for this would be USB 2.0 speeds. Looks like a very nicely constructed cable - look at the connection ends, and polished metal. If all you were doing is connecting smart phones to your laptop, this is the type of product I would buy.
The J&D cable appears to be a full-feature type-c cable, and should support every supported type-c data rate. I'm not in love with the picture of the product though. Doesn't look quite as nice as the Cable Matters product. If you wanted to connect two devices with full 10GB/s connectivity, this would be the type of cable I would get.
It is my opinion that the two products are good examples of a well made USB 2.0 Type-C cable and a cheaply made full-feature Type-C cable. The full feature cables have to include more pins/wires, and are thus more expensive to produce.

Technically incorrect, but essentially right.
Assuming both cables adhere to standards, the Cable Matters USB 2.0 Type-C cable is (most likely) missing the data pins & wires needed to transfer at the rated Type-C 10GB/s speeds; however, it should still have all of the power pins and wires to charge at 5V 3A. The J&D cable, presumably being a full-feature cable, should support full Type-C power (100W) and data (10GB/s) speeds, and will also charge a Nexus at 5V 3A.

So for just charging it would make sense to get the better constructed cable based on your observations?
At this point, it's more about the cable you use than the charger. Using a backwards 3.0/3.1 compatible C to A cable will get you the same speeds as a standard C to C cable in USB use. The chargers coming standard with the phone are C to charger, so Google seems to be indicating separate charging and USB use here. However, compatible untethered chargers are available in both the Google stores and elsewhere. Just make sure if you're not buying the Google charger, you get one with the right specs.

So, if I read your post correctly, (very good post btw), if I were to buy a charger for work, I should try to find a USB-c to USB-c cable (5V/3A), and a USB-c wall plug, because the USB-c standard is what gets you the 15W? Using a USB-c to USB-a cable, even if it was rated for 3A, would max out at 10W?

This is a bit misleading, and while I see what your point is, I urge caution using such general statements. A one amp charger with a Type-A port, a computer's USB 2 port, a USB 3.1 port, and a Type-C port connected to Type-C adaptors will all produce different charging rates for attached USB Type-C devices.

True, but I was talking about USB transfer speeds, not USB charging speeds, since Google seems to be indicating separate charging and USB connectivity use with these phones, as evidenced by them including separate chargers and cables with them. Actually, only the 6P has both, the 5X only has the tethered charger.

Yes, exactly.
Edit: According to what I've read, anyway. There might be something about 3.1 Type A ports that I'm not aware of which will allow 15W power. I know the 3.1 Type A port has extra pins. Just haven't been able to find in the 3.1 spec sheet a 100% absolutely for sure explanation either way. The Type-C specs pretty clearly spell out power states though, so I'm going to continue going by that. See attachment.
Second Edit: No, it would max out at 15 watts. The current I in amps (A) is equal to the power P in watts (W) divided by the voltage V in volts (V):
I = P / V.
3.0 Amps = 15 Watts / 5 Volts.
Or just buy a hard wired type-c charger like the one on the play store.

It won't power 100w, but I'm sure someone makes one that will.

I'm fairly certain Apple's USB-C charger will work fine, but it's $49 without a cable.
Google's offering is cheaper, has two ports, plus a cable so I'd wait for that.

You want a charger compatible with Qualcomm Quick Charge 2.0 for the 6P. Quick charge allows charging at 5V, 9V and 12V. The charger will supply the voltage/amperage appropriate for the current charge level of the battery. Most older phone chargers are 5V and will work, but will not quick charge the phone. You can, however, us a Type C to Type C cable and charge your phone from a MacBook Pro Type C connector.

That's a misnomer for the QC2.0 stuff. The usb-c to usb-c charger is automatically going to work with 5v/3a charging without the need for QC enabled functionality. Actually, there is some debate as to whether or not QC2.0 will even work with this phone if you have a standard usb-a to usb-c connector on a QC2.0 usb-a port.

Yes, the Type C to Type C has nothing to do with QuickCharge. It is a USB standard.
However, QC 2.0 works now on dozens of phones with Type A to Type B (Micro USB 2.0) connectors. If you connect it to a PC USB 2.0 connector, you will only get 5V! In fact, I suspect that even my USB 3.0 ports on my Gigabyte P5-USB3 motherboard also only supplies 5V. You must have a charger port set up to supply the higher voltages. If you look at the Wall/Car chargers that are QC2.0 compliant they usually have 1 QC2.0 slot and 1 or more standard slots that will only supply 5V.
Interesting point is the iPhone 6s actually has Qualcom QC 2.0 built in, but not utilized by Apple. The supplied charger with 6s is underpowered and a 6s can be charged much more quickly with a higher amp charger like that for an iPad or Kindle Fire.

My Zenfone 2 had QC2 with an intel chip but ASUS called it quick charge with their 'boostmaster' charger but in reality it was just QC 2.0. Samsung calls it adaptive fast charging but its still QC2 etc....the Nexus likely doesn't support QC 2 because it requires a license as another member mentioned which would add to the overall cost
Not sure what you think is misleading, but let me try to clarify:
1. If you have a QC2.0 compliant charger and a QC2.0 compliant device, then QC2.0 will work regardless of the type of connector on the ends of the cable.
2. iPhone 6s has the capability for QC 2.0 built in, but can not do it because it is not utilized. However, you can provide higher amperage to the device at the same voltage than what the standard 6s charger supplies and hence, it will charge faster (not QC 2.0 though).

Understood, but there are plenty of threads debating what the actual volts/amps will be on the phone if you use A-to-C with QC2.0 chargers. According to the spec it is 15W (9V/1.8A or 5V/3A), correct?

It will get the voltage/amps determined by the charger. The 6P is not QC 2.0 CERTIFIED. Google didn't go for the pretty sticker.
From the QC 2.0 FAQ:
Q6: Does it matter what type of charging cable is used with a Quick Charge 2.0 adapter?
A: Quick Charge 2.0 is designed to be connector-independent. Quick Charge 2.0 can be implemented with a variety of formats, including USB Type-A, USB micro, USB Type-C, and other proprietary connectors.
Quick Charge 2.0 high-voltage operation is designed to minimize charging issues associated with long or thin cables, allowing for a superior charging experience, independent of cable type.

You're arguing this in two different threads with multiple people trying to educate you on the power PIC controller interface. The chipset can handle the charging, but the actual usb power interface controller won't pass along those signals. It's not like applying a wire and getting charge -- there is a handshake that happens for the correct charging current and voltage to be applied.

Gotcha. The phone will identify the voltage requirement and the charger (assuming intelligent) will supply that voltage at it's rated amps. Actually, the default for all USB is 5V. If the charger does not get the handshake it will default to 5V. So a 5V/3A charger that is capable of multiple voltages will only supply 5V to such a device. Which is what the Google charger supplies. Most chargers will default to 5V and less than 3A however.
I will be interested in testing the Google charger and phone when I get it in my hands. The problem with charging is the change in resistance as the battery charges which is the point in multiple voltages. I like the new USB-Power Delivery setup, but there will be teething problem for early adoption.

At least Motorola claims it supports QuickCharge if I'm not mistaken. Apparently, though, it also has additional requirements for turbo charging to kick in... I looked at the Verizon charger, too, but a) there's not much info on its website, b) calling Verizon didn't help - they don't have a clue, and c) there is some comment / review saying that it "burned out" some user's battery (which is of course unconfirmed to be related to this charger, may have been something else).
Anyways, given the utter lack of info and the suspicion of harming the battery, I stayed away from it... not to mention the ridiculous $40 price tag.
On an other note, though, Verizon has the original Motorola TurboCharger (wall charger) at a 50% discount.

No USB-C device can support Quick Charge - it violates the USB-C spec. Any quality USB-C charger that is higher amp will TurboCharge a phone. Moto screwed up by using TurboCharging name with both QuickCharge and USB-C - they are different.
The Moto Z is absurdly picky when it comes to quick charge specs.
I have a Blitzwolf QC2.0 with a type C and a Type A connector in my wifes car, and it will ONLY enter quick charge if I use the Type C to Type C cable I bought from Blitzwolf.
It will not turbo charge if I use a high end Type A to Type C cable, but my wifes LG G5 will do so happily.
I also bought a QC3 compatible charger, with the cable integrated like the original charger, and this works too, and is faster than the QC2 charger.
Both are definitely charging at more than 10 watts, the maximum for 5V 2A mode chargers.
And in fact, using a Non-QC 5V 3A charger, caused my cable to melt, and start to glow.
Incredibly my phone charging port survived.
Blitzwolf may very well be the only brand that works fully, as I just bought a Chuwi QC3 power bank, and it will refuse to quick charge my phone.
But works on some others.
And on another note, I used the Type C to Type C in a modern laptop a while back, and when I plugged it in, my phone displayed the message about receiving quick charge.
If I'm not mistaken, the Type C spec allows quick charging, but only if you use C to C, with the extra pins it's able to keep better track of the charging process I guess.

Yes, it seems all matter of cables...!
I have a Blitzwolf QC3.0 too BUT I'm able to obtain "Turbocharge" indication only using a *single* micro USB to type C adaptor. This with every cable and every charger. Even when connected to a USB port!
If I use every other cable or similar adaptors (I've tested many...), the "Turbocharge" never shows (except original charger obviously...).
With Blitzwolf QC3 and this cable/adaptor I got a full charge from less than 5% in about 70-75 min... during the charge cable was OK, while the adaptor (with metallic/aluminium exterior) was quite warm but never really hot in dangerous way...
Here's more information than any of you probably care about, but I'm tired of seeing the same misinformation and confusion being thrown around (not just in the Moto Z forum, but in a bunch of others, too).

That's not true. Case in point: my ZTE Axon 7 and LeEco S3 both use QC 3.0 and both are USB-C. The common confusion comes from using "USB-C" (a connector) and "Type-C" (interchangeably used to refer to the connector and the power specification) incorrectly. Clarification below.

This is mostly true. "TurboPower" is the stupid name Moto uses to refer to the Type-C power specification. Actually, I'm being unfair: it's confusing that they called it "Type-C" in the first place and Moto took the opportunity to market the spec as their own thing.
Before going any further, let's use a common analogy to make the relationship between, wattage, voltage, and amperage easier to understand in broad terms. Wattage is the amount of water going through a pipe. Voltage is how fast that water is moving and amperage is the size of the pipe. 15W is 15W, but you can get there by having a tiny pipe (1A) with water moving really fast through it (15V) or a really big pipe (3A) with water going more slowly through it (5V). They both move the same amount of power, but in different ways. Got it? Good.
Anyway, Type-C has a fixed voltage and maxes out at 15W ([email protected]). Quick Charge 1.0 does only 10W ([email protected]), 2.0 does 18W (5/9/12V @ 3.6/2/1.5A respectively), and 3.0 does 18W with varying voltage (3.6-20V) and amperage (5-0.9A) to match. That is the advantage of QC over Type-C: a higher voltage can (usually) be run through those old and cheap USB cables without issue since voltage tolerance is determined largely by the phone and the charger. As long as the amperage doesn't exceed the capacity (gauge) of the wire, higher voltage is fine.
Amperage, though, that's what causes non-compliant or crappy cables to burn up. Really old or especially cheap cables can handle 1A max (heck, if they were built to spec, only 500mA for USB 2.0), but most cables of reasonable quality can handle 2A without much issue. They tend to use lower gauge (thicker) wires and should *not* feel warm at all when using it to charge. Some manufacturers (Samsung, for example) used to disable data on their USB cables and use it for additional amperage capacity, which is why you would occasionally buy a phone with a cable that wouldn't work for data transfer in the computer but would charge your phone just fine.
Moving on. Technically, QC 1.0 and QC 3.0 do not violate the Type-C power spec. QC 1.0 because it can't exceed it and QC 3.0 because it's variable. That said, QC 3.0 (and possibly QC 1.0, I don't know) require protocol negotiation; if that negotiation is lacking (in the case of the Moto Z), it's going to default to a "safe" charging rate (around 5W, plus or minus some). Your QC 2.0 does technically violate the Type-C spec because its voltage and amperage rates are fixed: you can get 5V at up to 3.6A. The "up to" bit is the important part. I have seen in various threads folks claiming their non-QC 3.0 phones will work with QC 2.0 chargers just fine and it's probably because the amperage tolerance is there (ie. it will actually allow 3.6A, violating spec) or it gets throttled (ie. sticks to 3A, keeping to spec).

All Type-C and USB-PD compliant devices are picky about the charge specs, not just the Moto Z. Or, at least, they're supposed to be for the reasons outlined above (namely the amperage). QC devices are less picky because it frequently uses higher voltage, which we established above as being much more tolerable for cables of varying quality.
Your cable melting and glowing is to be expected when you push 3A through a cable that likely can't handle more than 2A or so. Your phone charging port survived because it's designed to handle 3A.
I'm not entirely sure about which pins do what on a USB-C connector, but you're right in the C-to-C is the only connection that (should, according to spec) support Type-C and USB-PD (Power Delivery). The rate is negotiated via the USB Power Delivery 2.0 "power rules", which define four acceptable voltages (5/9/15/20) and variable amperage (0.1-5) to obtain charge rates as low as 0.5W and as high as 100W. "Type-C" is part of the Power Delivery spec, but is usually limited to only the 5V rule. I'm fairly certain the Moto Z does not support anything past the first level power rule, which is why you likely won't find the Moto Z to charge significantly faster with the TurboPower 30 included with the Moto Z Force than it does with its original TurboPower 15 charger. No clue as to whether that's a hardware or software limitation.
Also, to answer the OP's original question: any reputable (Anker, Aukey, Choetech, Belkin, etc) that uses an actual USB-C port will work. Most (if not all) dual port units will have a USB-C port that will work with the Moto Z (or any other Type-C/USB-PD device) and a QC 3.0 compatible "traditional" USB-A port. I have yet to find one that includes two USB-C ports and I really hate the ones with integrated cables.
My personal favorite is the Choetech for $16 since its QC 3.0 USB-A port is reversible: https://www.amazon.com/dp/B01AAGH8OY/
This Aukey is cheaper ($15) and would be fine: https://www.amazon.com/dp/B01E764DXM/
Here's a Tronsmart for $16, as well: https://www.amazon.com/dp/B018K7LHBU/
Even this $10 Vinsic should be okay: https://www.amazon.com/dp/B014F2NQ36/
Just for funsies, here's a spreadsheet of the Benson Leung cable and charger tests: https://docs.google.com/spreadsheets/d/1wJwqv3rTNmORXz-XJsQaXK1dl8I91V4-eP_sfNVNzbA/edit#gid=0
Interestingly, the $10 Vinsic is on his list of approved. So there. Go buy a $10 car charger and be happy.
I have the aukey 6 port usb charging station with two QC 3.0 ports, I am using high quality braided usb 3.0 to type c cables - I have tested both QC 3.0 ports and the other ports (using ampere) - Every port lists charging as "normal" - QC port 1 shows a min of 640mA and a max of 1040mA. QC Port 2 shows - min of 530 mA and a max of 980 mA. Regular ports 3-6 all show a min of 270mA and max of 870 mA. Not one port indicated it was ever turbo or fast charging. This same charger does fast charge my lg G5 and Samsung S7 Edge.
this one is verified to give the "TurboPower connected" message when plugged in.
From what I have read, both QC 2.0 and 3.0 doesn't turbo charge moto phones. Qualcomms QC charging works by increasing the voltage and decreasing the amps. So you can have 12v and 2amp for a total of 24 watts, but that won't turbo charge the moto z. Moto works on 5 volts but needs at least 3 amps. It is the amps that seem to engage the Motos into turbo charge mode, and they have to be at least 3 amps.
This Belkin model, for example, is what Benson Leung uses for his pixel xl. Its one of the few on Amazon that is USB-IF certified for 5v 3amp.

Here's more information than any of you probably care about, but I'm tired of seeing the same misinformation and confusion being thrown around (not just in the Moto Z forum, but in a bunch of others, too).
That's not true. Case in point: my ZTE Axon 7 and LeEco S3 both use QC 3.0 and both are USB-C. The common confusion comes from using "USB-C" (a connector) and "Type-C" (interchangeably used to refer to the connector and the power specification) incorrectly. Clarification below.
Moving on. Technically, QC 1.0 and QC 3.0 do not violate the Type-C power spec. QC 1.0 because it can't exceed it and QC 3.0 because it's variable. That said, QC 3.0 (and possibly QC 1.0, I don't know) require protocol negotiation; if that negotiation is lacking (in the case of the Moto Z), it's going to default to a "safe" charging rate (around 5W, plus or minus some). Your QC 2.0 does technically violate the Type-C spec because its voltage and amperage rates are fixed: you can get 5V at up to 3.6A. The "up to" bit is the important part. I have seen in various threads folks claiming their non-QC 3.0 phones will work with QC 2.0 chargers just fine and it's probably because the amperage tolerance is there (ie. it will actually allow 3.6A, violating spec) or it gets throttled (ie. sticks to 3A, keeping to spec).

I think you are propagating mis-information. If you want to catch up on why QC 2.0/3.0 violate the USB-C spec, here it is from the horses mouth:

Interestingly Qualcomm has QC 4.0 now and they call out integration with USB-C and USB-PD https://www.qualcomm.com/news/relea...livers-20-faster-charging-improved-efficiency
"Quick Charge 4 also integrates USB Type-C and USB-PD support, making the industry’s most popular battery charging solution available on the widest variety of cables and adapters."
USB-C has 24 pins while standard USB-A has 4. Quick Charge chargers (2.0/3.0) only have the 4 pins of USB-A - so if it can't use the data lines, then it can't quick charge via USB-C. Since there are only 4 outputs, plugging a USB-C cable into a QC 2.0/3.0 charger will not change anything. Still only 4 wires originating from the charger. The data lines are not allowed to be used for voltage, so your QC charger will only supply a fixed 5V to the phone. So no Quick Charge.
If QC3 supports [email protected] couldn't it supply power at [email protected] to turbocharge?
Looking for a solution to turbocharge my Moto Z and support QC3 for LG G5/Samsung S7.
The TurboPower 15 wall charger delivers hours of power in just minutes of charging. It includes micro USB and single USB charging cables so you can use it on compatible smartphones, tablets, digital cameras and more.
Have a Moto Z or another USB-C enabled device? The TurboPower 30 wall charger is USB-C compatible.
Looking for a car charger? Shop at Motorola Home.
