Well here we go again. For OnePlus to actually get dash charging to work they are using non-spec compliant cords. These cords, if not used in a dash charger, will potentially break your phone and/or wall plug. They do not regulate currents probably and will allow the phone to try and pull more wattage than the wall plug/USB port can provide. This can create high temperatures at the port of the phone and port of the wall plug. DO NOT USE THESE CORDS UNLESS IT IS IN A DASH CHARGER
do you have a source?
cause I think the cords are just the same, but thicker to handle the high current.
So you can use it on every usb-c device, it is even more safe than most other cords.
" ... and will allow the phone to try and pull more wattage than the wall plug/USB port can provide"
the Cord can't "ask" for more wattage, the cord is only the way through.

The cord, with a proper regulator, should limit how much wattage the phone is trying to pull since it's USB C. But OnePlus's cord does not. Go to the Google Play Store and search USB C Test and the application should come up to show its non-compliant.
So now the cord has a "regulator"... ?
Man, tell me your dealer..
Does USB C test work on OP3 or does it need a Nexus?
The cable actually matters and can destroy devices if not USB-C compliant. A Google engineer tests a lot of cables after destroying his Chromebook. Read up here: https://m.reddit.com/r/Nexus6P/comments/3robzo/google_spreadsheet_for_usbc_cables_with_benson/

On what basis do you say this! It has the right resistor. The app you talk about only passes if the product supports full USB-C USB 3.0 I believe. Try on a Nexus or something

Unless you tinker with the specific (kernel) settings, how can a phone try to pull and use more power?
The phone can only receive the amount of power wich the outlet of the wall charger/USB connection provides?? The only thing I can think of is the specific recistance of the original OP3 USB-C cable.
The less recistance, the more power the phone could recieve, but normally not more than the output of the connected power source.
Pls correct me if I'm wrong.

The phone will always request the maximum the cable can provide. If the cable is not properly made it will always report 5v 4amp. Since, it is reporting the 5v 4amp, it is allowing the phone to try and get that amount. This means the wall plug, if not a dash charger, is now being over taxed and will overheat to try and provide it.

I'm still not understanding exactly what you think is wrong with the cables? They have been said to have the correct resistor which is what caused issues with the other Cables.
The cables are said to have extra tech in them but I can't see why they wouldn't be dangerous or if anything similar was reported with VOOC cables.

Nothing blew up.
Stop spreading FUD.
If the source provides X a cable can't magically make it Y.
Else I would buy only such cables and lay it throughout my home wiring (to provide me more than the meter will count and add to my bill).
Besides OP3 specified it as "USB 2.0, Type-C".
Means basically - USB Type C plug, but 2.0 Standard.

As you have Nexus 6P, please could you make this test and report the results? Oneplus cable is not USB Type-C compliant because it's USB2 cable but that doesn't mean it's automatically unsafe or dangerous to use with third party chargers or to plug it to pc's. Please, could you do that test and report the results. :fingers-crossed:
Edit:
Quote from linked website:
"6P
adb shell “cat /sys/class/typec/typec_device/current_detect”
Or from a shell on the phone
cat /sys/class/typec/typec_device/current_detect
Results:
If the result is 2 an A to C cable is non-compliant
Possible values
0 – standard USB charging
1 – 1.5A type C
2 – 3A type C

If the cable test would report value 2, then it would indicate that the cable allows phone to draw too much current from the charger and could potentially be dangerous to pc's or wallchargers.
I already charged the phone with a power bank and provided oneplus cable.

Of course the app shows it is not spec compliant as it only checks it to show with USB-C spec
As it's a dash charging cable it won't be spec compliant with USB-C. It doesn't mean it will harm your device as there are circuits in the cable and the connector.

Hi all,
Can anyone point me to a known car charger which fast charges the G2? (Preferably not a $30 charger)
All but one of my previous car chargers only slow charge. I also just bought 2 from Amazon which claim to be 2 amp, but they also slow charge (just packed them up to go back).
Thanks.

It's my understanding that you can make one by shorting the data pins in a USB cable, but just remember to never, ever use that USB cable on a PC or else you'll damage the port.
I, too, am frustrated by LG's attempt to thwart fast-charge via normal USB cables. Once we have custom kernels, this will likely be resolved. I used leankernel on my GNex and had a fast-charge widget that would let me go from 0 to 100% in about 45 minutes.

This makes some sense as my previous phone was a GNex running CyanogenMod with Franco Kernel. 3/4 of my previously working "fast" chargers only slow charge my G2.
Strangely, when using LG's USB cable plugged into my laptop's USB allows fast charging.
I use a Palm car charger, it's the best one I've ever found, and they can usually be found for around $10. It will fast charge the G2, tested and confirmed.
Okay, I take it back, it doesn't stay on fast charging. After a minute, the slow charge notification pops up. But this is the fastest car charger that I've ever found, and I looked around for a while.
The G2 is capable of an even faster fast charge than what we are used to, and that's why other home chargers also show slow charge. It's not really slow, just not as fast as it could be.

It's a Nokia wireless charger stuck onto an igrip alumina car mount. And wired into a 12v outlet.
I bought this at Walgreen and seems to charge just as good as at home. 10 bucks the blue led is a little much at night tho..
Oh they come in any color you want. I use the cable that cane with my device that cable is thick so I'm assuming it's needed.

Yes, you are correct. But it seems that they are going "the extra mile" to make it more difficult...
For example, when I use my GNex USB adapter, it says "slow charge"... When I use an Apple wall charger, "slow charge". Unless I use LG's cable. I can't get fast charge to work with anything at all unless I am using LG's cable. Even then, it may or may not work with the non-LG adapter.
Can't wait for a kernel that has fast charge enabled. With the wireless storage feature of this phone, there's no reason to use MTP anymore, IMO.
So is it the cable or the 1.8a "base" that enables us to fast charge?

I'm 90% sure this has to do with the cable. Most premium USB cables are 24awg/28awg (power/data). The LG OEM cable is 20awg/28awg, and I'm guessing the phone detects the voltage drop in order to determine slow vs fast charge. FWIW, going from 20awg to 24awg yields an increase in resistance of 2.5x. I may be off base on this being the underlying cause, but I cannot think of any reason why I can fast charge on my 2.1A car charger only with the OEM cable, just like with the OEM wall charger. I'm going to hunt for a 20/28 USB cable to test this theory. In another thread, I said I was able to fast charge with regular USB cables on my car charger but I couldn't replicate it today. Phone would slow charge in all instances of USB cables, modified or not, on my 2.1A car charger.
yes, the cable is a difference.
other cables only show as slow charge with the same adapter.
now where to find these lg usb cables

Hey guys, just wanted to do a review on the TechMatte USB 3.1 Type-C to Micro USB Adapter! Since I don't have a standard USB to Type-C cable, I picked up a pack of two adapters. Though it's made of complete plastic, I feel it'll still be sturdy. It gets really snug with your micro USB cable and that's perfect, I've only been pulling buy the adapter when unplugging, don't want the connection between cable and adapter to become loose.

I give this product a 9/10! Only taking a point off because when I use it with my portable charger, if I use it one way, it'll say "Charging Rapidly", but if I flip it, it'll say "Charging".
Ask me any questions that you have!
I bought a pair of these on Amazon. I'd give it more like an 8/10. Reason being that the fit and finish of the assembly isn't perfect, at least on mine. They work fine, but they have a huge logo (companies need to market, I get it, but logos are often overkill) on each one.
I can't really complain, they do the job and they're cheap. Good simple way to get connected to your older cables, I guess.

I have these but be careful, they don't follow USB C standards. So if you hook an adapter USB A connector to some old legacy port on a pc or wimpy charger, it may try to draw more power than the charger or port can handle and damage it (the port or adapter, not the phone)
A Google engineer has been handing all these knock off manufacturers their asses on Amazon about it.

IMO we want out of spec cables. How else will we hit anything above the max usb A spec of 2 A? Just need to make sure that the chargers support 3A.
That's fine as long as they warn you that it's out of spec, which of course they dont. Standards exist for a reason.
If I were them, Id sell it as a "feature" and warn folks to make sure they use a 2.4 amp+ charger and not a usb 1 or 2 port.

Even with 2.4A you still risk a brown out and meltdown... albeit less so than using a 1A charger. But the risk is still just as real.

EDIT: Benson tested this one and says it is out of spec and he was surprised since the design has a fixed cable. Back to the drawing board.
No - that one is fine. The issue is a badly designed cable not adhering to allowed USB specs with a plug end that isnt USB type-C, failing to specify a pullup where it only charges at a rate that USB type-A or micro USB can handle (i.e. 2.4A max). If it tricks your phone to think you are connected to a true 3A source, it can burn out the charging source by pulling out too many amps. It works fine if you have a true 3A charger (which I have yet to see in any USB type-A format).
If a cable has the correct pullup to legacy USB standards, that would be equivalent to a safety valve for your charging device and it wouldnt be forced/tricked to push 3A.
So, for 3A charging, you need a true USB type-C cable at both ends going to a 3A charger (or direct mount). For any charging source with USB type-A, your known max is according to the old USB standard of 2.1A in most cases, although there are some type-A 2.4A options out there too.

+Mike Kendall As long as the cable you are using is spec-compliant with respect to the resistor identifier, meaning the cable identifies as a "Default USB Power" type, any USB Type-A charger should be safe.
If your question is which charger is best meaning will get you the best charging speed from an A-C cable to your Nexus, it's a much harder to answer . It depends on the wattage output of the charger in question, and whether or not the phone is able to negotiate with the charger to get that highest wattage level.

Contact TechMatte through amazon directly... They are about to launch a new revision of these with full USB-C spec, and will send out replacements for the old ones free of charge. I just contacted them and all they needed was my shipping address to send out new ones.
It's a pity they messed up the first batch, but their customer service has really impressed me thus far.
We need a synergy now. There's too many separate but insufficent discourses around. Also too much infollution. Let's discuss it here.
What we have to illuminate?
1) Best fast charger with type-a output?
2) Which ones charges fast (not only 3A)?
3) Are type-a chargers are capable to output 3A or not?
3a) If they are not, which wall chargers we should use for fast charging?
3b) if they are is there any (for example Tronsmart has a new 3A charger)
We may multiply the questions but we also need answers.
I know there's an article on droid-life but they only tested 5-6 chargers. We need more tests I think.
We have 1 rule: NO CAR CHARGERS!
I'm pretty sure that simply put, A to C does up to only 2.4A. Doesn't matter what wall charger you have. If you want full 3A fast charging speeds, C to C is the only way.

I second this. I have been digging into this the last few days. Here is what I have gathered. In order to be to "spec" USB A to C cables are only to pull up to 2.4A. USB C to C are only to pull up to 3A.
So, in my opinion it would be a waste to buy any USB A type wall chargers. I know I will only be looking at USB C type wall chargers myself. I mean, I want to take full advantage of and utilize the technology of my new phone to the fullest.
Now, in theory, if you had a USB A to USB C cable that was out of spec (3A pull) and a USB A wall charger that was capable of outputting 3A, it would charge as fast as a USB C to USB C. Like I said, in theory.
The problem that is going around right now is that the USB C side of a bunch of the USB A to USB C cables is trying to pull 3A, when it is only suppose to be pulling 2.4A max. The problem with that is, most wall chargers, usb ports on computers, etc can not handle outputting 3A. So, they can (and do!) brown out. (fry out / die / permanent damage)
I have been looking around for wall chargers with actual USB C ports on them, but I have yet to come across any. (Other than the stock chargers for the 5X and 6P and the ones on the google store) I will keep an eye on this thread, and will update when I do.
It looks like that the main issue is the a to c cable. I'm telling this because as I said there's a 3A pull-up capable type a charger with Qualcomm QC 3.0:
http://www.tronsmart.com/products/tronsmart-wc1t-quick-charge-3.0-wall-charger
It means; at least; that type a - micro usb is capable to push/pull up 3A but if the limit on a to c is max. 2.4A this cables are not capable. It's really interesting. I know nothing about cables technically.
But with my high school physics knowledge I can say that if type c corner may pull-up 3A from the charger and if the charger is incapable and becomes hot it means that the cable tries to pullup 3A and also type a corner of the cable may pull 3A.
So if the charger is capable to push 3A a to c may pull up to 3A.
Why we say a to c does only up to 2.4A then?

The answer for this question from Benson:
Tronsmart's Quick Charge 3.0 charger has a Type-A port, and if you read the fine print, at 5V, it is only allowed to output 2A. This charger is NOT capable of 3A.
Furthermore, you misunderstand the need for the pullup resistor. The pullup resistor is on a new pin in the Type-C connector and plug that doesn't exist on Type-A or Type-B plugs or connectors called CC or Configuration Channel.

A to C cables have to advertise default USB power which is 0,5A, because that it how USB used to work.
More current can be negotiated using a special combination of resistors connected to the data lines. There is 0.5, 1.5 and 2.4A, (and possibly more negotiations I don't remember)

May you be a little bit specific? We will get only 0,5A with a to c cables or it depends on charger's capacity?
For example I have 1 FrieQ and 2 Google a to c cable. Which ampere this cables will be able to pull from charger? 0,5A always or up to 2,4A max?
With a USB A to C cables which fulfils the specs, the phone will first see a legacy USB Port with 0.5A and then it can negotiate a higher current up to 2.4A.
What is possible depends on the charger though.
You may Google for 'USB DCP divider mode' to find more information about possible combinations.
USB C is going to be the standard in the future. I don't own a tablet, or any other devices myself. So I have no need for any type A adapters now. I am just going to stick with Type C to C adapters for my 5X. Seems the best way to go. I bought 1 x 3' USB A to USB C cable and it is only for hooking my 5X to my computer.
I bought the Vinsic charger and a 3' USB C to USB C cable for my car. Both were approved by Benson. The Vinsic charger is a car charger, and it has a 3A USB C Port on it. The 5X displays "charging rapidly" when plugged into it. (It also has a 2.4A USB A port on it as well, but you wont get full amperage when charging two devices at the same time) Sorry, I know you said no car chargers but it goes with the whole USB A is 2.4A and USB C is 3A, just like house chargers. Now, that Quick Charger 3.0 adapter is interesting. I wonder if the 2.4A spec only applies to USB A to USB C cables. Can a USB A to Micro USB cable pull 3A?
I am still looking around and keeping an eye out for more USB C house charges. I will post my findings.

I'm pretty sure that simply put, A to C does up to only 2.4A. Doesn't matter what wall charger you have. If you want full 3A fast charging speeds, C to C is the only way.

It is well built and works fine...almost the same speed as the OEM charger.
I picked up their Type C-C cable and charger and have had a week to compare them to the OEM units we received with our handset.
I was expecting marginal quality because of the low cost and unfamiliar manufacturer. When the order arrived, I was impressed with the packaging, which speaks volumes to me. When you make a quality product, presentation matters. Conversely, when your selling junk, you throw it in the cheapest plastic bag possible and call it good.
After using this cable and charger exclusively for the past seven days, I can confirm it's as good as the OEM. Personally, I like the Choetech cable better because it's sturdier in my hand.

They now have a power bank up on Amazon which will be my next purchase. I'm confident that it will be solid based on my experience with them to date. I saw a similar power bank that was given in a Project Fi welcome kit and I've been lusting over one ever since.

Sent from my Nexus 5X using Tapatalk
I bought a Nexus 5x from the USA, but I live in the UK. I will therefore need to replace the wall charger when it arrives.
For my old Nexus 5 I use an iPad charger. This is fast, and adaptable, since I travel a lot, I can switch the figure of 8 input on the iPad charger to whatever country I am in, and it allows me to carry only one charger and switch between Nexus and iPad charging.
I realise that the old iPad charger will be quite slow to charge my new nexus 5x. I would like a replacement that is at least as dependable as my iPad charger, but with the usb-c standard. The perfect charger would have swappable plugs, like the iPad, with a usb-c AND standard usb 2/3 ports.
Any ideas?
Nobody found an alternative to this yet? Is it at least possible to buy a standard, genuine, nexus 5x charger with a uk plug?
Can't you just use an outlet adapter?

I have the eu-plug but it should be available in UK model...
I only bought and adapter
Well, I had a Moto X 2014 with quick charger and I lost it, so my replacement was the 5X. In order to keep my previous chargers I bought a micro usb -> Usb C adapter. It's works pretty well for both charging and data transfer and isn't that expensive and you can still use your previous charger.

Remember that the OEM charger has an output of 3.0A so you might use a big charger, like the one of an IPAD or S6.

From what I understand though, the old USB formats are not capable of delivering 3.0A. It has to be USB-C. Adapters will turn your charge to 2.5A maximum.
I might be wrong, but have read a few things that suggest this. With my official Google charger I can charge my Nexus 5x fully in about 30 minutes.

I believe you are right, it might not charge at 3.0 A, but it did a good job with my 2.4A Aukey charger. I didn't measure the charging time, but it's aceptable. I can run some tests if your are still interest.

Hello,
I recently bought a Nexus 5X, and as you know it comes without a USB C to A adapter. So I ordered a cable from a china online store and will test it with CheckR. But if it isn't safe I was wondering if I could make an adapter that would connect the data lines to computer and the 5v line to an external power supply, capable of supplying 5V/10A. Does anyone know if this would work and how safe would it be?
The connections are shown in the schematic on the link(remove the space between goo. and gl)
goo. gl/yaSZZ0
Thanks for any help!
I can't figure out where the danger is here. If you have a charger that outputs 5v @ 1.0 amp, it's going to output that to the phone no matter what right? The phone is essentially the dumb end right, it takes what it can get.
I have cables now that according to Benson do not meet the USB C spec, and cables that do meet the spec. Both brands of cables pass the Checkr app test though.
Both cables say charging slowly on the phone when plugged into a low amp charger or a PC port. The only difference I've noticed is the cable with the 56k pullup resistor still says charging even when hooked to a port that is cable of rapid charging.
So best I can tell nothing can be damaged here, just if you get the "in spec" cable with the 56k resistor, it will always slow charge, even when plugged into a device cable of charging faster?
*edit* Just for clarification, the cable with the 56k resistor will do "charging slowly" and "charging", whereas the cable without will do rapid charging on devices that can output the extra current. So while I say slow charging, it's still capable of charging at a "normal" rate */edit*
A big part of the issue is that it can try to pull more current from the port than the port can supply, and possibly damage it. Once the port is damaged who knows how it will react or what it will be supplying. Most USB A ports aren't going to supply 3A safely that's where the concern is. On the unsafe thing here is more https://plus.google.com/+BensonLeung/posts/HakwCMmd346
You are essentially creating a powered hub with that, I've done similar to make a powered OTG. You should be able to charge from it if the power supply is correct. Obviously, it's on you to decide if it is correct and worth the possible risk.
So I get voltage is pushed, amperage is pulled. So is the problem only on incorrectly designed power supplies / chargers that dont limit their output current?
So far every port / charger Ive used my 5x has charged correctly on (only drawing what the port can supply). The only catch here is cables that Benson tested in spec (with the 56k pull up resistor) wont support "charging rapidly" on ports that are capable of it.

One thing to consider is that the USB A chargers were never meant to charge C devices, so it's not that they are all improperly designed, just that they are designed for a different spec. The PU is on the Configuration Control pin and is meant to configure the device to what the source is rated for, 56k will set it to "Default USB Power 500mA for USB2.0, 900mA for USB3.0". The charger lacks the PU to configure the device and the 56k PU in the cord is there to fix that and sets it to default values in order to make it work across all sources/ports. I found some C spec information from here if you want more to look at.
As long as the 5X was getting no more than it's 5v 3A and the source was safely providing the power then I don't see where the issue would be.

I'm more inferring that if there is a fire or melted plug, it was an improperly designed device. Any charger or power supply should be limited to a max safe current anyways, regardless of what the device or cable would like to pull.
Thanks for the link though, I had never really looked into why (how) it was reversible, or what the various resistor were doing. It's actually a pretty interesting read. It really strikes me as they wanted to create a do it all cable, but that just ended up making it really complex for no reason.
Ok so in the end the CheckR app claims the phone is charging with 3A and that the cable is unsafe but the phone says charging slowly and i tested with an ammeter and it's only about 350mA so the cable is safe. Apparently the CheckR app really can't be trusted.

Which cable are you using? It is not necessary for the 5X to draw 3A at all times, in fact it wont - even with the stock USB C charger. It depends on the current battery level, the heat, and the charger. And don't go by the 'charging rapidly/slowly' indication, it isn't consistent when the 5X is paired with Type A cables (compliant or not) and chargers. Using Ampere or Current Monitor is better to monitor the draw.

I'm using this cable: goo. gl/ayfgEk (can't post links yet). I did a test today and the result is: according to my ammeter at 27% battery the phone draws about 250-400mA. At the same time the Ampere app jumps from 190 to 540mA (it even went to over 2000mA but I didn't get a picture of that) so the cable seems safe to me. So am I missing something or the Ampere app really can't be trusted?

I'm using the cable here goo. gl/ayfgEk (can't post link yet) I think using a physical ammeter would be the best way to monitor the current. I will do some more testing(using both the Ampere app and my ammeter) at different battery levels. Will report back.
Also the site claims it's USB 3.0 but it's actually just 2.0 with blue plastic
[EDIT: sorry for double post looks like i still had a draft saved on the phone and accidentally posted it now]
I think the app can be trusted, but which charger were you using? Was it connected to a USB port? I would suggest testing it further. Even the Current Monitor app can validate compliant USB C->A cables, so you could give that a shot as well.
-edit-
But how are you using the ammeter to check the draw here?
-edit2-
You said you saw it shoot over 2A. That shouldn't be happening when connected to a USB port. It shouldn't exceed 500mA.

Interesting.

It was connected to a computer USB port as that is the only I plan on using it(I'm not gonna use it with an AC charger) I connected a short USB extender between the cable and the USB port and the extender has a cut 5v wire so I can connect the ammeter in series. Will test the current monitor app.
EDIT: It only went over 2A according to the Ampere app, at the same time the ammeter measured 260mA. This is the reason I'm questioning the app's reliability.
I'm curious to know how much the 5X pulls via that cable when connected to a 1A or 1.5A charger. If it stays within the amps the charger is rated to provide, then it should be good.
