Charge and USB connection - Nexus 6P Accessories

I have an Android Box plugged into the screen in my car. It's running an Android Auto receiver. So I can plug my phone into the box, using a USB-C to USB-A cable, and Android auto works. Now I have a fully functional android auto, with one problem. The phone is charging at less than 500 mA. Does anyone know of a cable that could possible charge the phone with a car charger at the same time it's plugged into the box?

You are mistaken here. The cable does not limit the charge that goes through the phone. The limit that you are seeing on your phone is due to the USB port that you are using which has a max output of 0.5Amps.

Correct, but I need to stay connected to that usb port for data so I thought there might be a cable that had two USB-A ports on it. One for data and one for power.

greeting,
I bought a Nexus 6p and looking a charger (for car and EU wall charger).
I'm interested in whether it is compatible with QC and QC 2.0 3.0?
He prayed to the recommendation.

For Nexus 6P charging and date sync, the Type-c to Type-c cable is better than USB-A to type-c cable.

Phone Charger

I ordered my Nexus One without a charger and was wondering if I could just use my iPhone USB charger with the supplied USB lead?
I'm guessing that's all the charger is right? Just a charger with a USB port or a miniUSB charger?
all nexus one orders come with a charger. They also come with a usb cable, back-slip carrying case, and a headset.
Not when you want it shipped to the UK.
It adds a charger to the basket so I just deleted it
If it is in the box I'm guessing I will still get the US charger and can just use an adaptor to use in the UK..
Actually I have used the apple iphone charger with usb cables to charge a BlackBerry 8900 and a G1. I would guess it would work for this, but its your phone and your money if you burn it out
yeah youll get a US charger then. In any case all USB chargers are the same. if you have any USB charger with a USB port, you can jsut connect your included USB cable to the charger.

this has micro usb i believe and the charger's you are talking about are all mini-usb. not compatible.
this is not true. the side that connects to the charger itself is still all regular USB. both mini and micro USB cables have the same pinout and electrical output standard.
i know. i'm saying that the end of the cable that plugs into his G1 will NOT FIT into the nexus one because it's MINI USB and the nexus one is MICRO USB.
thats not wat hes asking. hes asking if an iphone wall charger (which simply has a standard USB port on the other end) will work.
Ohhhhhhhhhhhhhh sorry

i think your wrong with the "all usb chargers are the same"
my usb charger (micro usb) for my bluetooth headset will not charge a cliq, it its the same in appearance, but somehow it is actually different
however, the charging cable i had when i had a cliq charged my bluetooth, but I avoided it because it was obvious the 2 chargers where different.

correct. Certain chargers have different amp ratings. For example, GPS chargers generally require higher amount of amperage than cell phones, and certainly a lot more than bluetooth headsets
the g1 charger will not work with the nexus one. I have both phones. The behold II charger will work with a nexus one phone. my gf had the behold ii phone.

You mean plug-wise it won't work right? Because I just took my USB charger, took a Mini-USB to Micro-USB converter and used the G1 charger to charge the N1 and it works.
I'm not sure about the Nexus One but I know on the N900 you could have the problem of that charger not supporting the Data pins(D+ & D-) to communicate with the device and establish a power draw rate, in which case the charger won't work with the phone. The solution was either clipping the data lines in the USB cable, or shorting out the pins in the charger. I doubt the Nexus will be that picky about chargers though.
Usb Charger
Hi,
I just have ordered mine from US. I am from Europe and i will definitely have the problem with the originally supplied charger.
As i am aware all usb ports works with the same voltage - 5V., only amp rate is different. We just need the output amp rate of the original charger and have to be careful not to exceed it. The smaller amp rates are OK (just the charging time will be more.
For example in the originaly stated data from Google says:
"Power and battery
Removable 1400 mAH battery
Charges at 480mA from USB, at 980mA from supplied charger"
Just one to confirm is the original charger amp rate 980mA as Google stated?
I think you'd better to buy a new mobile phone charger for your nexus one for safety.
Just tested plugging the N1 in directly to computer using a miniusb cable w/ microusb adapter and works perfectly. It detected the phone and did that Mount SD notification. I mounted, transfered couple GB of files w/ no interruptions. Also, it charges it like normal.
Usb standard is 5V, most chargers with usb output should be 5V. The Amp is determined by the Voltage and (electrical)resistantce, check Ohm's law.
However the chargers are probably limited to a certain amperage(max amp output). All chargers I've seen have inscripted input and output values, as long as output values are within usb standards it should be ok.
I have an iphone car charger with usb out. It stays in the car and charges my family's gadgets no mather the manufacturer/type of device, as long as it supports usb charging.
So theoreticaly it should work. To be safe check the output values on the usb charger.
If n1 came with the american charger you can check the output values of that against the iphone charger output values.
Would a simple US 2-pin to UK 3-pin plug adaptor be fine?
The few gadgets I've got with US plugs I would just buy a UK version plug but since you cant just buy these in any shops (yet) will just have to wait and see what they supply first.
Anyone here with the US charger could you post the output values please

[Q] Charging cable

I have just bought up my transformer ( Love it ) but it's at about 10% battery right now... I take the cable that came with it (the usb one) and plugged it into my computer but it is not charging ? Any idea what's wrong with it ? when i plug it into the charging unit it works fine though
i've heard it has to be turned off for the USB charging to work....
Like off as in screen off or off as in complete off ?
It will not charge in your computer. You have to charge it in the wall.
Sent from my Desire HD using XDA Premium App
One of the pamphlets that came with it said the screen has to be off in order to charge it using a computer's USB port, cause the screen uses too much power and a USB port doesn't output as much, its best just to charge with the ac adapter. Nothing is wrong with your unit, thats just how it works.

Turn off the screen and it will charge. (you don't need to turn it off; you just need a black screen) It is very, very slow though.
My wall charger never charged my tablet so I am awaiting a replacement. The USB charge is MUCH slower than the wall charge. We are talking about maybe 4-5% an hour -- max with the USB cable alone.
Connecting this thing to a computer will NOT charge it. Even a normal 5V 1.2A-2A charger won't charge it fast enough. I used a 2A charger and it trickle-charged for over half a day and managed to clock in @ 50pc. I think the unit uses hardware info from the ASUS charger to detect the charger. Any other charger wont do.
Isn't the cable and charger USB 3 and charging is at non USB 2 values (voltage and current).
Good amount of mis-info in this thread...
The unit *will* charge from computer USB, assuming the USB port provides enough amperage (not voltage). I have not yet measured out the amps used, but it's on my list of things to do...
In order to charge from computer USB, the display on the Transformer needs to be off. The unit can be on, but it must be asleep.
The adapter that comes with the transformer provides 15VDC via extra pins which loosely resemble USB 3.0. These are *not* USB 3.0 data/power specs, however a USB 3.0 extension cord could be used to lengthen the existing adapter.
Any USB car adapter should work to charge this in sleep mode, similar to a computer USB port. In order to "fast charge" in a car, however, you'd basically need to use an AC inverter with an ASUS Transformer adapter.

Tried a 2.1A 5V charger. Took about 8 hours to charge @ 50pc. The ASUS charger is rated at 1.2A.
is the only way to plug the device into your PC or laptop via USB on the dock?
you cant use the proprietary charger cable to do USB data transfer with the charging cable USB component?
ie....to do data transfers via USB (not the memory card), the only way is via the dock?

No, one end of the charging cable is regular USB and the other end (tablet-end) is proprietary. You can transfer files over by connecting to your computer's USB.
awesome, thanks.
do you think that if you get a male/female USB converter, you could plug in a USB memory stick device or a mini hard drive device and have it work fine in the charging cable just like you would if you were to plug in a mini hard drive into one of the usb ports on the dock?

Charger HTC Question

Hi all.
Could the charger of desire work normally(when check in about phone it must be show AC not USB) for the HTC desire HD and Inspire 4g.
Thanks
If it shows AC that means you are charging through a power outlet and when it's charging by USB you are charging it through a USB cable connected to a computer
Charging through AC is faster then USB

PC has only 500mA current output, your wall charger has 1A output
greater current faster charging-but this does not mean that battery has not its max. charging current!
higher charging current can easily damage your battery and cell phone.
I charge my phone with Xperia charger, with Kindle charger, with Nokia charger and many more. So far I have no problem with my battery. As long as on the end of the cable you have “micro-b usb” and stable (troublefree) electric transformator to supply that cable you can charge your battery. The time to charge may be different but the result is the same.

As long as the two data cables are connected to eachother, the DHD will recognise it as a wall charger, and it will use 1 ampère. Instead of the 0.5 amps when connected to a PC (when the data cables aren't connected to eachother).
You can buy "charging only" cables. They always charge at maximum rate and do not transmit any data. Usually come with external battery packs etc.
Just to clarify some. (Talking about USB2.0 as 3.0 has a little higher power)
The USB on computers are powered by the motherboard (if not using extra PCI USB card).
Usually the motherboard gives about 500mAh to each USB host. If that host has 4 USB connectors all those connectors share the 500mAh.
And just be careful to not go above 500mAh as some (older) motherboards or even add in card's cannot handle the extra power and will fail to work(permanently).
So a charge-only cable will not make a difference in this situation, same goes for using multiple USB ports as that also brings extra problems with it, as power/voltage doesn't flow in just 1 direction (when using 2 poles). You could blow out USB voltage regulators when connecting different USB power leads together.
As for the phone side you can also use a 5000mAh power source, as the phone will 'take' what it needs. For DHD the max charging power is about 800mAh~900mAh if I'm not mistaken.
As long as its 5V and somewhat stable.
So if you want to charge the DHD (or any other USB chargeable phone, mostly all of them) as fast as possible use the original wall charger.
If you have to do it on the PC/Notebook unplug as much USB devices as possible, so most of the power can go to the phone.
Also make sure the screen of the phone is turned off as that's the biggest battery drain of the DHD. Thus also making charging slower (when on).
I'm using htc charger to charge my e-cigarette . It's works good.
If you plug it into USB socket, and enable "Fast charge" option, does it do anything? Does it block the data transfer and acts like a wall socket (1A) ?

TF700 charger/cable requirements?

I was planning on using my iPad charger to charge my phone, iPad, and TF700 while on the road. It puts out more than enough current at +5 volts but doesn't work with the TF700. The Asus charger outputs +15 and +5 and works with the Asus cable and an OEM cable, and also works charging my phone using a micro-B cable. Is the TF700 charged using +15 volts?
The TF700 booklet says it can be charged from a USB port, which is +5 volts. While that may be an impossible task on a PC, it still means that the TF700 can be charged using a USB cable and +5 volt charger. Why doesn't it work? Has anyone gotten a 2A +5V OEM charger to work with the TF700? Is there a pinout diagram for the Asus cable and charger anywhere? Thanks.
Not sure if this helps, but the keyboard dock (unlike the tablet itself) can only be charged from the charger, not usb, so it must draw more power than a standard usb.
It's also possible your Apple charger usb port is pinned to only work with "apple approved" products? Have you been able to charge other devices from it?

I don't have a dock nor am I trying to charge the TF700 from a PC USB port. The Apple charger puts out +5 volts to anything plugged into to it and the TF700 apparently "knows" when the Apple charger is connected to it because it turns on if it's off.

It will charge VERY SLOWLY on 5v USB while turned off. Will not charge via 5v USB while on. The TF700 requires at least 12V/2A to charge while on. 15V/1.2A is what's recommended by Asus (based on their proprietary charger specs).

You are correct. With the TF700 turned off, an hour of charging with the 2A Apple charger had increased the battery level from 29% to 34%. I expect the TF700 to be fully charged in only 14 hours!
Thanks.
Have you considered a power inverter? I use this one with my A100 though I use a FM transmitter to charge my phone.
Somewhat related to this: in the past, when using devices that have a power block with a USB port and a charge/sync cable, such as an iPod or even my Galaxy Nexus, I've used a USB extension cable to give me a little extra slack. For some reason, that doesn't seem to work with the Infinity. I've tried three different USB extension cables and the tablet never shows that it's charging. Is there a certain USB cable I can use for this?

Are you using a USB 2.0 or 3.0 extension cable? It's my understanding that the Infinity uses USB 3.0.
You need 15v to charge the Pad (I kept thinking 11, but the adapter says 5V or 15V output). This makes sense since there are more pins. Standard USB has 5v rails (ther are 4 pins, I 5v power, Data+, Data-, ground). Since our chargers are 40 pins, my assumption is that there are more pins dedicated to charging and multiple pins dedicated to data (possibly a few that are dedicated and some that are for whatever data is being passed through (assumption)). If the adapter is outputting 11v then it can send more power through the cord and multiple pins can push electricity through. When you are only pulling 5v (i.e. most AC->USB transformers) you will need a lot more time to charge, hence the trickle effect (and don't turn on the screen!)
It can be charged with 5v if the tablet is off.
There is a jumper in the USB cable itself that kicks the Asus charger into 15v mode so it doesnt accidentally fry your devices if you plug in, say, your cell phone to charge for a bit.
To make a custom cable just throw 15v across three pins in the connector (5v each). You can find all the info here: http://forum.xda-developers.com/showthread.php?t=1633747
Yes, i know its for the prime, the connector is exactly the same, the pinouts SHOULD be identical.
DIY approach?
I've got a TF700T and a TF201 dock and a misplaced charger. I ran into the same trouble that a lot of people here did ....... generic chargers not working, USB on my computer only trickle charges the tablet, nothing for the dock, etc.......
After much poking around I learned that both require 12 volts to charge. That said I dug thru my junk and found a 2.2a 12v DC wallwart. I hacked apart a USB extension cable for it's female end, broke out my breadboard and put together a 12v USB connector... that after several days of charging and draining.... charging and draining .... works like a champ.
So to be a bit more specific, pin 1 that's normally 5+ volts I'm supplying 12+. Pin 4 is ground same as always and that's it. If you wish let me know I can probably throw up a little illustration or something.
Since I did that I've refined the whole thing a bit, cleaned it up, wired everything directly and heat shrinked the whole assembly.
It will charge both together or either one by itself in just hours EVEN while using them..... heavily. No overheating, no troubles.

I think the cable type might only matter after the ics.30 update when I was on the ics.26 I could use a standard extention cable, I had my device plugged in when I updated and my device stopped charging, and I freaked out thinking I broke something. But after finally removing the extention my tablet would charge. I have not tried to use the extention cable since so I don't know if it works with jb.

The Asus charger switches its output to 15V from 5V when a USB3 plug is detected. If you need an extesion cable to charge the Transformer, you'll have to use USB3 extension cable. If you want to use this charger on other devices, be sure to use a USB2 cable to not to fry it with 15V.

USB charging on some amps, AC on others

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
Sent from my Nexus 5 using Tapatalk
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.

Oh thanks for that tip. I'll order one on Amazon right now and update this thread

What happens if you connect an Apple device to one with the shorted pins?

Tested the new USB cord on all ports, charges as AC. Thanks a lot
