With the advent of the S4, and its higher capacity battery, one could understand a higher charging current. However, I seem to have uncovered some findings that the charging system on the S4 is a bit more complex than first thought!
This is a bit techy, and assumes you have a basic amount of electrical knowledge, ie voltages, currents, resistance etc., but I'll try and keep it as simple as possible for anyone who may not!
To explain: The mains charger supplied with the S4 is a model number ETA-U90UWE, rated 5V @ 2A. However, the phone will ONLY charge at full current (which as I have measured so far, depending on what the phone regulates it to, typically sits in the region of 1.2 - 1.5A), when using the supplied charger (or possibly one of equal or higher current rating, depending on how it's configured internally), AND the supplied usb cable, OR any other usb cable, provided its shielding (the metal outer surface of the connectors) is connected at BOTH ends of the cable. Use a cable that doesn't have this shielding, and the charge current drops, regardless of whether there is plenty of current available or not. Use a different charger with an unshielded cable and the current drops even more, again regardless of whether it can supply plenty more current.
My assumption on this, is possibly an effort by Samsung to avoid the scenario of sticking 1.5 amps down a flimsy cheapo cable, the wires of which will likely be too thin to carry it.
After doing some probing around with a meter, I have managed to find a slight difference with the charger itself, compared to a generic one. In a generic one, the two data pins are usually just shorted together, which tells most phones that it's a mains charger rather than a USB port. On the Samsung one on the other hand, the pins appear to be shorted together, and also connected via resistors across the supply line (known as a potential divider), which holds these shorted data pins at a certain voltage. This is what tells the phone what sort of charger it's connected to.
Attached are a couple of diagrams to show the difference between the two chargers. There are in fact various setups of resistors that different manufacturers use to set the charging current, so it's quite easy to run into compatibility issues!
To make this a little less confusing I have done some preliminary experimenting, and I set out my results here.
For the test, I used combinations of 4 different usb style mains chargers: an apple iPhone one rated at 1A, an iPad one rated 2.4A, an HTC 1A one, and the genuine S4 one. With these I used two cables - the supplied Samsung S4 one (which is shielded), and a cheap generic one (which isn't). I started by measured the charging current directly with a meter, by using a very short usb breakout lead I've made, enabling me to interrupt the 5V line. However, I soon noticed that the use of any extension cables, even shielded, can lessen the chance of maintaining a good shielding connection, so I continued the exercise relying on the "galaxy charging current" app to get a reading.
Charger.................... Cable................ Current (A)
=====================================
HTC 1A.................Generic..................... 0.5
HTC 1A.................Samsung S4..............1.0
Apple 1A...............Generic......................0.5
Apple 1A...............Samsung S4..............1.0
Apple 2.4A............Generic......................0.6
Apple 2.4A............Samsung S4..............1.3
Samsung S4.........Generic...................... 0.8
Samsung S4.........Samsung S4...............1.3
So as you can see from these results, the original charger makes a difference, and the supplied cable (or a good quality shielded one) makes a further difference. If you have any further findings please feel free to add them here.
I can see that this is going to confuse some people, as it has me, as I'm sure some will inevitably try charging up their phone on generic chargers/leads at some point, with potentially long charging times resulting!
.
Very nice findings! Thanks for sharing them.
Not only what you say about longer charging time, but also discharging may occur (it has with me) while connected to the USB. I left my phone with USB tethering and it shut itself down after a couple of hours (it was low on battery already). I wanted to keep all the accessories in "new condition" in case I sell the phone in a few months, but I guess this justifies using the official charger and usb lead.
I hope someone can shed some light on the detection mechanism or the particular characteristics of the official cable so it can be replicated in generic ones.
From your findings, also Appe 2,4A charger has some control on the cable used, thanks.
Yes, but you won't be able to get more than about 0.75A out of it even with the samsung s4 cable.
You could try to add an extension cable to check if the charging system needs exclusively an original samsung cable from the charger to the phone.
Original samsung charger => extension cable male/female => original samsung cable => phone
PS: is there an app to check the charging current?
My experiments used an extension cable, that's the one I made into a breakout cable. So no it doesn't change by adding a cable.
There is an app, called galaxy charging current, which I tried also. In the 0.75A results above it showed a max permissible current of 1000mA, with the fully samsung setup it showed 1900mA. In the lower scenarios is showed up as 460mA. Other than that it doesn't tell you anything, it literally just shows you a max possible current, not the actual current it's drawing.
I've found out what the issue was, my generic cable was obviously a cheap one and wasn't shielded! I have edited my original post to re-explain.
Also I did a further test on a PC usb port - the Samsung cable allowed for 500mA, but the unshielded cheap one only allowed about 350mA, so (as pintycar found out), the phone actually carries on discharging in this case!
Interesting post.
I've been trying to mod a car charger so that the s4 draws more than 300mA so far unsucessful. I'm going to add in the 82K resistance and see what happens.

Hi,
Using a 5a digital bench power supply, I took a normal micro USB cable, cut it in two, added in the 82k resistors and tested.
Before: 450ma, after 1.73a
Then using a clamp meter I tested it with a 2amp Asus tablet charger - it varied between 1.48 and 1.61 amp.
I have since built a few more cables - one to use in my car (again 2 amp charger).
All in all, it works very effectively. Thanks for the initial research (saved me having to open my charger.)
BTW I suspect it is the charger where the resistors are, not the cable, otherwise the phone would try to pull 1.5a + from a laptop if you connected it.
Left my samsung cable at work so will test it tomorrow (if I remember)!

Interesting. So basically for us laymen, you are telling us to use the original charger and cables to the extent possible ... right?
Can you clarify to me what an unshielded cable is? Maybe with a picture? I've got a blackberry's cable at work connected to my PC.
At home, I also have a cable and charger that I got with my Nexus S (I think this says Output 5.0V ~ 0.7A).
Would this be a problem or can I get by with these?
Thanks
I've been using the Samsung cable+charger+USB extension cable and charging the S4 usually takes about 4 hours, I'm going to try with just the Samsung cable next time and see if it makes any difference since people are saying that theirs can be fully charged within less than 3 hours.

Hi,
I believe (guess work here ) that only the original charger "needs" a shielded cable - could be checked by shorting the ground and shield on one side and see if it works at the higher current - if I am bored I may do it - it probably checks the shield and limits the current if it is not there (note I have not tested this so only going by the first posters findings).
BTW a shielded cable has a wire mesh around the 4 internal cables - this mesh avoids external interference messing with the signals. Can't see it affecting the charging though BUT shielded cables tend to have thicker internal cables so could be related to this.
I have it charging at 1.7a on an unshielded cable (thought he power strands are thicker than average) Shielding should only affect the data transfer speed, not the charging current.
If the Nexus S has only a 700mah charger then this will not be able to provide enough current for high speed charging and could easily burn out - nice smell, dead charger, not much else. therefore only use a normal unmodified usb cable (and it will charge at about 450mah).
W.
all this would eexplian why the charger that camewith my S2 dosen't appear to charge my phone fully over night...
For what it's worth I'm charging with a Note 1 charger...a thick shielded cable via the S3 docking station....and getting 900mah...
will get my original cable tonight and have a go tomorrow...
interesting read, my s4 lead and charger are still in the box and I'm using my nexus 10 ones phone charged from about 30% to full in just over 2. may have to change the old HTC £2 lead I've got connected to my works pc then, maybe why it's struggling to charge when playing music. guess this is one way to get people to buy more expensive cables
Very interesting read, thanks TS.
My original charger and cable set is still in the box; I've been using my Mom's old Galaxy Note charger.
I'll try the original cable + wall mount and see how fast it is compared to my current charger.

I'm not sure if shielded vs. unshielded is the difference - probably wire gauge is the difference.
For example, if you shop at Monoprice, you have two options for USB cables: 28 gauge cables, and 24/28 gauge cables.
For wire gauge, lower is larger - the 24/28 gauge cables have thicker wires for the + and GND lines. A pure 28 gauge cable is likely to drop voltage a bit at high currents, and my observations have been that most newer devices, ESPECIALLY Qualcomm-based ones, are VERY finicky when it comes to input voltage drops.
As to the charger itself:
Apple chargers are almost guaranteed not to charge at full current, as they don't conform at all to the USB battery charging standard. Some newer Android devices do have at least partial detection of Apple chargers, so they may charge at 1A if an Apple charger is detected (any Apple charge, even 2.1A ones).
It sounds like the included official charger is a tablet-compatible one. Samsung tablets expect D+ and D- to be held by the charger at 1.2 or 1.8 volts (I forget which). As a result, Samsung tablets will not charge from standard chargers (like an N7 charger), but standard devices (like an N7) will charge from Samsung tablet chargers.
Now, the question is: Does the GS4 *require* a Samsung tablet-style charger, or did Samsung just include a tablet-style charger because it's backwards-compatible with standard devices? (less part numbers to track in inventory).
A useful pair of points would be: Using the same cable, does the Samsung charger behave significantly different from a Nexus 7 charger?

@slickromeo
One+ cables are deliberately not following USB Type-C standards.
(As far as I'm aware) they are configured to work optimally with One+ products.
I have multimeter. Where exactly would one test to see if the resistor used in 56 kΩ?
I'd imagine one would have to cut open the connector and visually verify the existence of the resistor. I think there would be too much variables involved to just connect the multimeter to a couple of pins, but I could be wrong.
EDIT: NVM

+Eric Hawkins Unfortunately since USB Type-C is such a new standard, at this point you sort of need some specialized equipment. I've been using this, which is publicly available on Amazon as well : https://www.chromium.org/chromium-os/twinkie
If you have a Chromebook Pixel 2015 in dev mode, there's some simple terminal commands I can share that can verify if a cable is good or bad.
I'm going to work on seeing if there's anything I can do on the Android side as well, maybe a battery charging statistics app.

I'm confused on the One Plus cables - they say they are 2A cables on their website, not 3A. So if they are only pulling 2A and im using 1.8A blackberry charger, how is that harmful to my phone? I guess in other words, how can I still use the One Plus cable with a charger safely?
I have these cables http://www.amazon.com/gp/product/B01...cm_cd_asin_lnk and I did not get the charging rapidy . Not sure if these work I will try again tonight or tomorrow.

Hey guys I'm in the process of setting up a store specific to Type-C products (type-c.io - not up yet). I'm in talks with supplies from Asia about getting the correct cables and was wondering what would you guys pay for cables shipped from North America?
@xray49er when you say you got the cable listed at http://www.amazon.com/gp/product/B010VFFU1W/ref=cm_cd_asin_lnk and it did not rapid charge your Nexus 6P, where you using the stock charger included with your Nexus 6P ?
@xray49er
Edit #2, I Purchased a 5V/3A car charger that only charged at 1.7amps (false advertising), are you certain that the charger you purchased is truly 5V/3A? test multiple cables, together with the GSam Battery Monitor app to see how many amps its charging
@slickromeo No because this is a usb A to C cable so I used a fast charging chrager that was 5v/3a. https://smile.amazon.com/gp/product/B0122P71FC/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1
All the cables in question are designed like the OnePlus USB-C cables, Basically if your using a device that doesn't charge at 3A you have nothing to worry about
Anyone tried the cable matters ones?
They have a usb 3 to usb type c cable

Hi guys, I'm looking at these cables.
It has a data sheet, is it possible to tell by this whether its in spec?
Everyone, once again, remember that there's NO WAY to tell if the USB A-C cable is compliant by just plugging it in.
It's pretty complex.
The Google Engineer wrote how to do it: https://plus.google.com/+BensonLeung/posts/jGP5249NppF
I bought these:
http://www.amazon.com/gp/product/B00S8GU544?psc=1&redirect=true&ref_=oh_aui_detailpage_o09_s01
I have no issues with them...And the guy from Google didn't review them. They also seem to be on the "compatibility list", based on the description of the item at least.
I've been playing around with the Android App Ampere - I'm wondering if it might be possible to identify bad cables based on the charging rate - based on this post, they should be 2A, not 3A. If you compare the power usage before and during charging, you can deduce the charging rate.
On another note - I'm putting together a database of usb-c compliant cables here to help people find compliant usb cables. I'm primarily focusing on usb-a to usb-c cables as that's where the biggest issues appear to exist. Right now the listings are based on Benson's reviews, but I'm planning to expand it to include additional cables once I find an accurate way to test cables.
I bought these awhile back:

You got your links messed up. FRiEQ links to Belin and vice versa.
It lists "USB Fast Charging @ 5V 3A" in the description, so it's unlikely to pass by Benson Leung's assertions that cables that list 3 amp charging speed typically don't adhere to the spec.
Disclaimer: All of these items were sent to me by Tronsmart for a fair and honest review.
Backstory:
Tronsmart I a well-known accessory manufacturer known for their cables and chargers. This is my first experience with their products because I usually end up purchasing most of my cables/chargers when I first get a new phone (I used qi charging almost exclusively until this current phone). This year things changed as I’m sure everyone is aware; the USB Type-C standard was initially very confusing for both consumers and accessory manufacturers alike. At first it was hard to find any Type-C accessories let alone ones that were probably in spec. This presented an issue for consumers trying to buy a cable that wouldn’t potentially brown out their charger, cause a fire, or harm their brand new Nexus 5X/6P.
I initially purchased an Aukey Type A-C cable off Amazon, and some OnePlus Type A-C cables/microUSB adapters. Soon after purchasing those items, I learned from Benson Leung that the majority of manufactures weren’t following the proper standard, and intern were using the wrong resister. Now while this was great to know, it also made it hard to buy a product with confidence considering that many if not all of them were potentially dangerous to use. Benson Leung went one step further, and began testing cables, chargers, and other products then posting reviews stating whether or not each one met the USB standard. The initial Tronsmart USB-C car charger fell victim to this problem, but thankfully it was corrected with their new car charger you will see below.
Tronsmart sent me a wide array of items to review on here with each one meeting the proper standard as verified via Check-R, and Benson Leung (except for the car charger as of 12/23 which has not been tested)
Here is are some pictures of the items that will be reviewed:
Tronsmart USB Type-C 33W Car Charger with Dual USB Rapid Charging and Quick Charge 3.0
<MODERATOR EDITED - SPAM REFERRAL LINKS DELETED>
First I will delve into an item that I know will be used on a daily basis, and that’s their car charger. The charger itself features both a USB Type-C port and a USB Type-A port to meet all of your device needs. The USB Type-A port uses something Tronsmart calls VoltIQ which will charger at 5V/3A max meeting the needs of most devices out there now. On the other hand, the Type-C port features QUALCOMM’s Quick Charge 3.0 standard so you can future proof your car by getting this charger. The Type-C port will charge at: 5-6.5V/3.0A, 6.5-9V/2.0A, 12V/1.5A(Max). This should allow the Nexus 5X/6P to rapid charge via the Type-C port, and charge at ~1.5A from the Type-A port as an in spec cable should.
I plugged both Type-C and Type-A cables into the ports to see how each one fits. The Type-C cable seems much more secure than the Type-A which is something that I’ve noticed when testing the car charger. I tested the car charger using Tronsmart’s USB Type A-C, C-C, and MicroUSB-C cables/adapter. Here are some screenshots showing the charging speed of each one on my Nexus 6P:
Update [12/25] I used the car charger on my 7+ hour drive yesterday and didn't have any issues. The C-C port was use for that part of my trip, and I plan to use the A-C cable via the Type-A port on my drive back tomorrow. I will add another update on how that goes after I get home which will be late Saturday, so the update will likely come on Sunday as a result.
Update [12/26] @MrKaon brought a good point to my attention; the car charger works perfectly fine, but it is not in spec for the USB standard. I personally did not encounter any issues with the car charger; however, the Type-C port cannot use QC 3.0 alongside the Type-C fast charging because it goes against the USB standard as outline HERE. I hope Tronsmart fixes this issue as they stated in the google + post, but all of the cables (A-C included) are in spec. The car charger is the only item that is still not correctly meeting the specification.
Update[12/29] After speaking with Tronsmart, and reading through this google plus post I'm still not sure how I feel about the charger. It does technically go against the charging standard as outline in section 4.8.2 which is further detailed by Benson Leung and the USB standard he is referencing (download). It seems that there is still a significant amount of confusion regarding the new standard. According to Benson Leung, Qualcomm has their Type-C quick charge wrong as it currently stands; this created more issues because Qualcomm told Tronsmart that its QC3.0 standard was correct when it still goes against the USB standard. To sum things up it still isn't using the standard, but it works perfectly fine as is. I'm still using it daily with a C-C cable without any issues, and I plan to until someone shows that it could cause damage to my phone/charger/car.
I used the A-C cable during my ~7 hour drive back home today, and didn't have any issues with it. I also tested both ports simultaneously, and did not notice a drop in current; this would be great if the charger was up to the proper specifications, but its not. I will wait on Tronsmart to make a updated on as they mentioned in their google + post I referenced. If Tronsmart sends me an updated one I will post a newer review on it in this OP.

Tronsmart 6[ft] USB Type A-C 2 pack
Tronsmart Type A-C 6[ft] Cable 2 Pack
I know many people still enjoy using their legacy chargers rather than buy complete new Type-C ones to replace them, this is where Tronsmart’s USB Type A-C cables come into play. These cables come in a pack of 2 (1 white and 1 black) each cable measuring 6[ft]/1.82[m] in length. Since the cables are using the Type-A port they can be used in more places than your convention Type C-C cables. I always keep a Type A-C cable in my backpack, along with a C-C cable just in case I need to plug my phone into my Surface Pro 4 or a PC for any reason.
The build quality of these cables is great, the cable itself is made out of your typical materials, and is somewhat rigid. I assume the cable will become much more flexible as time goes on, but it’s really an observation more than it is an issue for me. The connectors at each end are solid, and feel like they will last a long time by design. The USB Type-C connector is a matte plastic and tapered so it will not interfere with any cases. (it seems to work just fine with all of my cases so far including the CaseMate, and Ringke Fusion that I tested it on). The cable feels nice, and I plan to use it along with their C-C cable on my road trip tomorrow.
I tested the cable and verified that is passes via the Check-R app on my 6P. The dimensions of each end of the cable were measured with my digital caliper and will be listed below so everyone can check and ensure it will work with their intended case. I also plan to create a spreadsheet listing all of the cases, and cable compatibility given my vast assortment of them.
Update [12/25] I spoke with Tronsmart regarding the earlier mention of the cable being 'in spec', and they said all of their Type-C products have been sent to Benson Leung for review. They also noted that due to the holidays it might take a little longer before he posts about them officially. I am confident their cables will pass the test based on what I have seen as well.
Update [1/7] Benson Leung has reviewed and approved the Tronsmart A-C cable. This confirms my earlier tests of the cable. Bensons Review

Tronsmart 6[ft] USB Type C-C 2 pack
http://www.amazon.com/Tronsmart-USB..._UL160_SR160,160_&refRID=1G77XXSTWZGMBC089VAT
When it comes to Type-C cables, there aren’t many 6[ft]/1.82[m] cables out there to use with the factory Google charger without paying an excessive amount of money. I purchased the Google 22.5W dual port Type-C charger back when I bought my phone, and while it is very nice (so is the 1.82[m] cable) it was costly. The Google cable retails for $19.99 or the charger with the cable is $39.99; this might have been okay a few months ago, but now there are more choices for a fraction of that price. The Tronsmart USB C-C 2 pack comes with 2! of these cables for only $15.99 USD (as of 12/23). These cables are every bit as nice feeling (if not better in some ways) than the Google one I bought a while ago. I like how Tronsmart includes both a white and a black cable allowing you to choose the color based on where you intend to use it, and what one you enjoy more.
The connectors at each end of the cable are exactly the same as the previous one; this means the connector still features the tapered design, and matte finish which is fine with me.
Update [12/25] I used the C-C cable while driving for 7+ hours yesterday and it performed just as you would expect. I also used both cables in my Google Dual Port Type-C charger to charge my wife's 6P and mine last night. The cables have been working great, and my wife enjoys it more than the stock cable because it's much longer, and has a better build overall.
Update[12/25] Part 2: Tronsmart also mentioned that a C-C cable should not have a 56K pull resistor, or any resistor as noted in "3.4.2 "USB 2.0 Type-C Cable Assembly" for instructions on how to build a legal C-to-C cable. Adding a resistor would be wrong". I really appreciate Tronsmart's great service, and how they reached out to me with this information. I rarely see companies go to these lengths without first asking, but Tronsmart did this on their own without me having to ask. I'm going to buy some more of their cables because they have excellent service, and I could always use more cables.

Tronsmart decided to also make a MicroUSB-C adapter so you can use all of your old microUSB cables. These adapters also come in a 2 pack (1 white and 1 black) just like Tronsmart’s cables. I only have a handful of cables left over (primarily for my Nvidia Shield TV PRO), but these will still get used for a variety of reasons. I usually carry a USB Type A-C/C-C cables around, but this adapter is more practical in a different way. I can easily carry this in my backpack just in case I wanted to leave out my other cables, and need to charge my phone. The majority of people I know still use a microUSB cable to charge their phone, and this allows you to charge your 6P via the old cables. It is very small (easy to lose unfortunately, I wish they included a key fob like OnePlus did) but brings exactly what you need if you need to charge your phone but only have access to microUSB cables. I plan to carry one of each cable, and these adapters around with me because I like to be over prepared rather than under-prepare. I also have the TechMatte microUSB adapters, but their quality is far lower than the Tronsmart ones. The adapters remain consistent with Tronsmarts other Type-C accessories and feature a tapered body which makes them less susceptible to breaking. I can’t find any flaws in these adapters other than they don’t come with some form of holder which would prevent them from getting lost easily.

Tronsmart 33W Dual Port Type-C, Type-A Wall Charger
Tronsmart Dual Port Type-C, Type-A 33W Travel Charger
Overview
Tronsmart is on a roll with all of their great new products being released. They Dual Port Type-C/Type-A wall charger is no exception with a familiar designto the other dual port charger they sent me. The charger is small enough to easily bring in your bad, and it has the advantage of packing both a Type-A & Type-C port for maximum versatility. I am going to bring this with me to school on a daily basis as a means of an emergency charger/long term test.
Packaging
What’s in the box
A dual port charger, and some basic documentation with Tronsmart's usual contact information.
Build & Design
I've been enjoying the other dual port charger I was sent because of its nice compact form. The addition of a fold-able plug gives the charger the extra portability you need when carrying one around. The charger features Tronsmarts signature glossy edge coupled with a nice matte plastic body. A high quality feeling plastic is used which gives it a better feel than the stock Huawei, or the Google 22.5W dual port chargers.

Charging
The Type-A port will charge using Tronsmarts Volt IQ up to 5V/3A, while the Type-C port uses Qualcomms Quick Charge 3.0. I have tested both ports with my 6P, a dock, Shield Controller, and external battery packs. The Type-C port will only push up to 5V/3A and not the QC 3.0 which is good. Tronsmart designed the charger so it would identify the phone, and provide only the current it could handle. This is the same idea behind their Type-C/Type-A car charger I reviewed above which is still working flawlessly. If there are any concerns over the use of QC 3.0 via the Type-C port please refer to the links I posted in the car charger section for a better explanation.
Here is a breakdown of the charging by port:
Type-A: 5V/3A
Type-C: 3.6-6.5V/3A, 6.5-9V/2A, and 9-12V/1.5A
Picture of my 6P, and battery pack charging from both ports (the 6P is "rapid charging", and the battery pack is charging slower because it was nearly full)
Summary
Tronsmart made another excellent charger using the tried and true design language that should last for a long time. I like the versatility of the foldable plug and inclusion of both types of USB ports. I would buy one of these as a gift without hesitation given its performance build, and Tronsmart's exceptional service!
At the request of Tronsmart I removed the 'hide' image tags for the car charger so the pictures can be seen immediately without clicking on each one.
Update #1 [1/12] Tronsmart is adding a PTC (positive temperature coefficient to all of their Type-C products) This is also known as a thermistor to counter some issues people had with the cables. Tronsmart stated that people who did not keep the cables dry during use/clean experienced issues, but I wouldn't worry about it as this time. The addition of the thermistor is more of a preventative measure to ensure there are no issues for anyone despite using a cable incorrectly. I have not experienced any issues personally with their products, and I will continue to use them on a daily basis unless something prevents me from doing so. I was told the Type-C products that I currently have will be replaced which is going above and beyond in my opinion. I will update this statement with any new information as it becomes available.
Update #2 [1/12] PTC is not the standard, but rather a step above in terms of safety. I wanted to add that all of these cables are 100% compliant and meet the USB specification as outlined with Benson Leungs approval. Tronsmart is going above and beyond to ensure consumer safety with their products. No other USB Type-C cables on the market current incorporate a thermistor, so with Tronsmart's revised cables you will never have to worry. (the stock Google cables do NOT have a thermistor) I believe Tronsmart is trying their best to instill confidence in their products, and stand above the rest. This is my personal opinion based on my communication with them regarding issues I've had/seen.
Very professional review! Thanks! Got the tronsmart type c car charger and the type c to a cable:good: Actually I had found the new tronsmart car charger before but didn't find any review here.

Thank you, I will post an update after my ~7-8 hour roadtrip tomorrow. I'm going to use it to keep my Nexus 6P and my wife's 6P charged during the trip. The charger seems to work just as well as my other Type-C car charger (except that one has a fixed cable), and I like the ability to use a longer cable if I want to.

I fixed the link in my signature thank for you the heads up. Next, I was driving all day yesterday and I said I would update it when I had the time; it was noted in the OP that I would be out of town, and update the OP when I have the time because of that. I have a few minutes now so I will add some more to it. I do this in my free time, so please keep that in mind.

I'm well aware of his product reviews as I mentioned very clearly in my OP. Benson Leung doesn't ask companies to send him products, but rather he buys them and conducts testing independently. He doesn't need to approve every cable in order for it to be approved. Check-R is just as accurate, and other people on Amazon who own a Pixel tested it the same way as Benson which resulted in the cable passing the test with flying colors. You cannot say "without his approval don't buy it." when there are tons of cables inspec cables that he hasn't tested. No one can seriously expect him to test every cable hence the Check-R app, and other people conducting their own tests within the same standards.
The A-C, and MicroUSB-C cable/adapter pass Check-R just fine; I see no reason why the C-C only wouldn't as well, but I don't have a Type-C port on my laptop or adapter to verify that. I highly doubt Tronsmart would make the A-C cable compliant and then make the C-C non compliant so it's safe to assume that it is indeed compliant.

My car has a bluetooth puck that is powered by a USB port. I read that if you have something connected to the Type C port of a car charger and then connect another device, the charging ability to either device drops like a rock. (I currently have an OMAKER 6.6A 3-port USB Type A charger).
Can you replicate this? I doubt my BT puck needs to draw a huge amount of power, but it definitely has no battery and has to run on power (this was intentional, because I wanted the puck to turn on the moment the car is turned on and turn off with the car).

I'll test it with my wife's 6P and mine on both ports and let you know. I'll need to make sure both batteries are lower so they will draw more power, then let you know how it performs.

Benson doesn't reviews C to C cable only A-C cables and car chargers (already disapproved other Tronsmart charger) after searching Car Charger Thread I find out his opinion about this charger:
Please read the language in section 4.8.2 closely. It prohibits a proprietary charging method, which is what QC is, from modifying the voltage at the charger or the phone side. It's not possible to be compliant with both at the same time.
The way I read the spec, it is also against spec to charge legacy devices at higher voltages (ie an older phone with a MicroB port and supports QC) out of the same Type C port.
Click to expand...
Click to collapse
The spec prohibits it because it allowing it would cause significant confusion between two different methods of varying Vbus in a Type-C system. USB PD is the officially sanctioned method, and has some important advantages over any of the existing QCs. Specifically, you will NEVER see a QC hub or charging+data port on your computer because QC completely takes over the USB data lines. USB PD does not do this and there are already fast charging hubs on the market that also hook up USB 2.0 and 3.1 data lines.
Also, allowing it would potentially cause problems with legacy A-to-C cables by changing Vbus, it affects the reading the adc on the device side would read from CC.

Thank you for the link, I read through the Google + posts then amended the OP to reflect what you referenced. Now, despite the car charger not being compliant, the cables are still perfectly in spec and work fine. I appreciate the link, and information. I tagged you in the OP, then inserted the link you provided so other users can have a look at it.:good:
So the important part, does it work properly like the stock charger? AFAIK and researched, Tronsmart made a 2in1 charger (QC 3.0 + 5V*3A) in one port, that's why it's not in spec. But so far on your review, it works perfectly, and is giving 2700ma when charging.

It works just like the stock charger and will give 2.9-3A when the battery is low. I can take a screenshot later when I drain my battery enough and post it in the OP. I know its not up to the correct spec, but it still works fine. I can't recommend people use it because its not correct, yet I haven't had any issues to suggest its unsafe in any way. I have a different car charger (JOTO I believe) and it has a fixed cable which chargers at 5V/3A as well. I'll test both and take screenshots so you can see the rates each one charges at.

Good to know that it's working properly and PERFECTLY. =) Read the whole thread on reddit. The only issue is, you can't mix QC 3.0 and 5V*3A(Type C charging) in one port. Something about the guidelines.
Tronsmart did it anyway, and made it work. Dunno what the issue is about anymore.
While Benson Leung did great on pointing out the defeciencies in the market, I think this scare is already blown out IMO.
But more importantly, thank you so much for the review. ??

I don't know enough about electronic circuits to say there won't be an issue seeing as I'm finishing a degree in Petroleum Engineering which is quite different. I'm not concerned about it killing my phone unless evidence shows otherwise, but I can't state that people should buy it because of what was mentioned. I still really like the charger, and I will continue to use it daily because its nice. I hope the issue gets sorted out sooner rather than later. I PM'd Tronsmart about the discrepancy, and I will post their response in the OP. I think out of spec A-C cables are more of a hazard personally, but the Tronsmart ones are in spec are made correctly.

Interesting, I find that aukey also released a similar charger with quick charge 3.0 and the type c port(the same as the tronsmart one). Also put the quick charge 3.0 into the type c port. Can't post the amazon link here now. You can search"aukey type c charger" then you can find it.
OP Updated [12/29] with even more information regarding the Type-C standard. It creates more confusion, but also clears some other things up.

According to Benson Leungs post that charger doesn't meet the USB standard. I think Qualcomm is misleading some of these manufacturers by having their QC 3.0 standard not meet the USB one.

Anyone know if this one is safe to use?
So shortly after receiving my Nexus 6P I began hunting for a car charger that could supply 3 Amps if needed to my device...you know....in case of zombie apocalypse and the power grid goes down..I could still charge my phone :silly:
I found there were very few available. The first I saw was back ordered for weeks. Then I came across the Tronsmart charger. It was available on Amazon with Prime for like $22. The downside was it did not include a USB "C" cable, but now I see they have an updated version that has the USB "C" cable attached for a bit less. That'll teach me to rush out an buy something!
This is not totally a "con" since I am sure we have all been there where the cord attached to our car chargers breaks over time. So you would have the ability here to simply replace your 3 Amp USB C cable if that happened.
Testing: It seems the Nexus 6P is a little finicky and must be reallllly hungry (low on battery) for the charge current to get near 3 Amps. I drained my 6P down to 44% and tested the current on the manufacturer supplied charger in the house. It peaked at 2.85 Amps. I then took my phone out to my truck and threw it on this Tronsmart car charger. It peaked at 2.80 Amps. I am confident that this product works as advertised.
I also tested the type A port and it had no problem supplying 2.4 Amps to the 6P and also to my work phone LG G3.
This is a solid, rugged device. I am impressed enough to order a house charger from them as a back up for the one supplied with the 6P. It is designed for the 6P as well and also contains both A and C ports on it.

I have a ton of Tronsmart products, and I use the car charger daily without having any issues I wouldn't trust Ampere to give you accurate charging stats as far as the current goes, but charging time can be measured. The only true way to measure the current is with a multimeter and there aren't any C-C ones yet that work without a computer.
I have their dual port wall charger (both the A,C and A,A ones) and they're great! You can see my review of the chargers via my signature; if you have any questions about their products let me know. I speak with Tronsmart on occasion and I could answer any questions you might have.

Yeah, I tried Ampere and GSAM Battery monitor and both showed the same. I have a USB inline ammeter for the A port. I am very happy with the car charger and the quick charge capabilities.

I've been trying to find a more accurate way to measure the current being drawn from C-C chargers, but I haven't found one just yet. I was talking to a friend about making a C-C multimeter from a Raspberry Pi, or running a parallel wire from the C-C cable to measure current from. If we find a good way to measure it I will post about it, but so far I'm happy with mine too.
Anyone who owns a nexus 6p and has tried to buy a longer usb a-c cable than the 6 inch cable that Google provide will know just how hard it is to find a good quality cable that meets the new usb-c standard and won't potentially fry there charging device by trying to pull 3 amps.
Google prevent the usb a-c cables from damaging charging devices by placing a 56 kohm resister in the usb c end of the cable and many cheap cables have failed to do this or they use the wrong value of resistor, there is a simple free app that allows nexus 6p owners to check cables to ensure they are safe to use. I am happy to report that these cables pass the safety checks and are safe to use with nexus 6p devices.
These particular cables are very well presented in a functional box, the larger of the two cables comes with a Velcro strap to help keep it from tangling very handy if your traveling or don't keep your cables constantly plugged in, this is a nice little touch from Choetech and adds to the premium feel of these cables.
Both cables feel like they're thick enough to withstand alot of heavy use and will hopefully last a long time, I tested both cables with my laptop and was getting good data transfer speeds and I have tested both with numerous different chargers and also get good charging speeds, very comparable to that of the Google provided cable.
I am very happy with these cables and hope to get alot of use out of them, I would quite happily recommended these to anyone after a usb a-c cable, I have seen many cables that are dearer than this for just one cable, here you get two really good quality cables for a value price. I got these cables at a discounted price for a honest unbiased review but I would quite happily pay full price for these.

Have you by chance checked any other cables from usb-a to c that you have came across that you would recommend ? If you just use the app provided that means it is safe ?
Yes I also own a belkin 2m usb a-c cable that is very good but no better than the Choetech cables, the belkin cost me £15 though for just one cable as it was an emergency buy from maplins. I bought a cheap eBay cable originally, it worked with my old car charger but then my phone refused to charge from the Google usb c charger that night. A reboot fixed this issue but some research led me to discover the issue with usb a-c cables.
Because of the price and quality I highly recommend the Choetech cables.
Yes the checkr app let's you know if the cable is safe to use. You have to make sure it is connected to a computer / laptop for the app to work though, it won't work with a charging device.
I also get this cable bundle to review at price £0.99. It seems still available for review now. You can also apply one at a good price from Choetech official website: http://www.choetech.com/Support-review.html
I went for the 3.3ft USB-C to USB-A + 3.3ft USB-C to USB-C pack to go work with my Nexus 6P. Cables are a great length and I can leave it charging in the car while my passenger is using the phone at the same time. I am very happy with mine.

Yeah I also went for this combo pack. The cables are great and help me out around the house and in my car. The type C is in my car permanently from now on. Works great with their in car charger and charges the phone up in no time. The other one is in my work bag for emergencies. Definitely top quality products quality and worth getting.
