Micro USB Cable

I might be crazy but it seems like only certain cables able to charge my phone under the USB charging moniker while others say AC POWER. I assume the cables that say AC POWER are charging my phone faster. Is there a way to tell which cable will have the higher power output? I am looking to buy one on amazon.
Thank you
p.s the one that came with the phone says AC POWER.

I've found that the cables I have that say 'LG' on them charge better.
I've used cables marked 'Samsung', 'Motorola', 'Sony Ericsson', and 'HTC'. All of them seem to have issues charging my Nitro.

It's not the cable that determines that. It's whether you connect to a power-only USB port (i.e., USB power adapter) or connect to a computer USB port (which will charge at a lower rate, but still works). Also, different USB adapters charge at different rates. The one that came with the phone charges at 1.2A. Computer USB ports are limited to 500mA (= 0.5A).
That said, I'd recommend a USB cable from Monoprice.

I've bought about 6 of these cables over the years. You can't beat the value here. The cables are thick and well insulated, USB 2.0 Certified Sync and Charge cables. I've never had any issue with them. They've been used for my Nexus One, my wife's Moto RAZR and of course for my current Nitro.

**WARNING: Oneplus USB cable might damage your phone and charging device!**

A Google engineer has taken it upon himself to test various USB type-C cables and unfortunately he's discovered the official OP USB cable might damage your phone/charging device while charging by inducing it to draw excess power from the device it's plugged into (PC, wall charger, powerbank etc.)
Check out his G+ profile update for more info, refer to attached screenshot for the part where he mentions the OP cable.
All his Amazon reviews if you want to get another reliable cable to replace the OP USB.

Wow,
so we need a different cable + changer or just a different cable?IThay talk also about RAVPower battery..
Bah, they release a cable that is not compliant to USB Standard......

The original OPT cable is just not fully USB-C compliant. It can throughput 2A, which is the max draw from the OPT, but USB-C is specced for a 3A maximum. As long as you use the original cable not for devices like the Nexus 6P, 5X or the Pixel (which DO draw 3A maximum), the original cable is fine to use with the OPT.

Unfortunately not many people know about this little quirk of the OPT cable and in many usage scenarios people do share chargers with other devices which may draw 3A, damage the charger and any other devices connected subsequently. Oneplus should at least state that it's charger/cable is only meant for their hardware if it's going to put out mono-use cables like these.

The problem is OnePlus were the first company to really push a USB Type C device, there cable actually has the exact same issue. Most of these companies based there design off of the OnePlus version since that's the phone they were promoting them for. No damage will occur unless you have a faulty charger since there are fail safes built into all of those as well. The only items that will even try to pull 3A are the new nexus devices and the Pixel Range. Those devices would charge a lot slower with a USB A to USB C cable anyways so I don't know why people would. These cables are still absolutely fine for data transfer, and they are in fact just like the OnePlus USB-C and Zuk Z1 USB C cable. Saying this I did contact a few of them and the only one that has gotten back so far was Orzly who said they already have new cables in production.

the oneplus 2 and zuk z1 work with all of these cables no problem!

Iam going to replace it with iOrange-E USB Type C, and it is braided!

This is kind of a stupid place to post this.
Maybe post it in a different phone forum that also uses type C, since the cable has no issues when used with the OP2

You're assuming the oneplus charger would never be shared with other phones, some of which might request to draw 3A and damage the charger, no? Please think twice before you type. Thank you.

So wouldn't it be okay as long as we use these cables / adapters only with OP2?
I don't care if it would not be compatible with 3A phones / tablets. My phone is OP2, not Nexus or sth. else. When I have a specific device that needs 3A, I'll surely look for alternatives.

Considering most warranty claims would be denied for not using the OEM charger/cable (there's been a few OPO users denied warranty for this exact reason), no I wouldn't (and don't) use anything other than OEM or specifically licensed accessories.

Yes, it's perfectly fine to continue using your OP2 charger and cable with your OP2.

Good news!!! I just got in my Pixel yesterday and tested a load of new cables from Orzly and the OnePlus Cables and adapters! Bad news is the OP are def out of spec even the adapter! Good news all the new Orzly cables meet specs video is uploading now!

Correct a OnePlus 2 only tries to pull 2.4a anyways so its fine to use with everything only issue is the newer devices that try and pull 3a like the nexus phones and pixel

New Orzly cables are in spec!

So would it be bad for my external battery if it draws an output of 2.1A?

OnePlus USB Type C Adapter,not cable?

I don´t get it.. Sorry for the question but I´m confused :
Can I use my original Oneplus cables to load my op2 without damaging it? I have only one original oneplus power supply. Can I use the orignal cable with e.g. a samsung power supply?
Thanks!

Yes of course you can. No Oneplus phones or chargers have been damaged by "out of spec" cables. My OP2 charges just fine on the USB3 port of my PC, the PC hasn't fried itself yet.

Using a non-DASH charger and non-DASH cables?

I am thinking about buying the Oneplus 3 since I haven't changed my phone in a long time. I have a few questions about the charging.
Is the DASH charge just the wall adapter? Do I need to have a DASH charge specific USB-C cable?
Can I get DASH charge with a regular USB-C cable to DASH wall charger? (I am asking this because I use long cables because of the location of my outlets and workstation, ~10-15ft)
If I charge with a basic, QuickCharge, or non-DASH wall adapter will my charge speeds be basic or does it revert to QuickCharge (with quickcharge adapter) because it is using the SD820 chip? Also the same question if I use a non-DASH powerbank (I only need a small powerbank not the big ones they are making)?
I am not sure if this should be place here or in the Accessories forum. Please let me know thanks.
Thanks for the help.

1. For DASH charging you need both the adapter and the cable, both are specific and AFAIK there are no aftermarket alternatives.
2. No, with standard cables you won't get DASH speeds. Wires in normal cables are simply too thin to handle high current of DASH.
3. If you're using non-DASH charger and/or cable, you'll max out at about 1.5A, so a bit less than half the speed of DASH (could be slower, depending on hardware used). QuickCharge is not supported, it'll work at standard speeds.
4. Same logic applies to power banks. And DASH capable power banks don't exist (yet?), so it doesn't really matter what bank you're using.

On a side note do you know about the Oppo VOOC power bank (6000mah) since I read Oneplus is not making a DASH power bank anymore. Have you read about its DASH use or where to buy it?

Sadly I don't think this will ever exist ... OnePlus commented about cable length and they said they can't make it longer due to technical limitations (physics ...). High current = high resistance = lower max length.

Type c charging cables

Hello all. I have a quick question. I have bought a type c charging cable that has just arrived, it was sent from in my country to my location in less then 3 days. Off ebay And after purchase I read about how type c charging cables can destroy your devices if you buy a knock off, or a cheap cable or not made properly, by any means this cable was 13.00 AUD. It's 3 meters and it looks very thick and quality looks good. It is generic though. No branding.... So I'm wondering if it would be okay to just use this as a charging cable, and use the original for File transfers. I also have a Spigen cable on the way but I do not want to wait to use this one. Is there any chance that this will be okay to use?... Attaching a photo of the cable

The htc 10 doesn't use USB charging; it uses Quick Charge 3.0.
USB charging has its standards, separate from the connectors and separate from Qualcomm's standards.
Qualcomm states that QC works regardless of cable and connector. However, the htc 10 is picky about the cable and I've not found a rhyme or reason for it. I have a Type C-to- A cable that won't QC but several micro cables that will with a micro-to-C adaptor.

Basically the cable must have a 56k ohm resistor in the type c connector which tells the phone how much power to draw to prevent over current. Usually this is signified by a longer plug and the resistor should be stated in the ad if you can remember where you bought it from. From eye balling the cable you photographed it looks fine. I think it's more of an issue with Nexus phones anyway since the 10 uses a different standard in order to maintain compatibility with qc3.0.

More accurately, the resistor tells the USB-C device that it's hooked up to a legacy "device". Type C to anything being legacy. Anything but type C weren't "designed to handle" 3A of current that the USB Power Delivery can output at 5V.
So if you have a Nexus 6P or a Pixel or whatever that uses USB PD:
if you use a type C to type A cable with a 56kOhm resistor, the phone is going to know that this is a legacy device and it won't attempt to draw more than the "Default USB Power" which is 5V0.5A for USB 1.0/2.0 and 5V0.9A for USB 3.x.
But of course the device will also look past it and see what output current the charger actually advertises it is capable of and then charges at that current the charger is capable of..
But, here's the big problem.
What if you use a type C to type A cable with a 10kOhm or 22kOhm resistor?
That cable is going to tell the device that it's
a) not connected to a legacy device (56kOhm resistor would mean legacy)
b) it IS connected to 5V3A or 5V1.5A (10kOhm/22kOhm resistor respectively) output.
It's going to try and draw 3A of current if the cable has a 10kOhm resistor in there, whether or not the charger can actually output that.
Danger here is that different chargers will respond to that differently.
The charger can either fail spectacularly (read: explode, catch on fire, something bad) or it will just trigger OCP (over current) and not charge if it has the protection or it will just try and cope with it delivering as much current as it can and potentially overheat and fail in some fashion.
Imagine hooking up your Nexus 6P or Pixel to your laptop with a "bad" type C to type A cable.. Those ports are not going to be able to handle that kind of power unless they're something special sauce.
For a little bit more cohesive explanation, read this
http://www.androidauthority.com/usb-type-c-and-3-1-explained-656552/
As for our device, we don't use USB PD. Some have said that the HTC 10 is compliant with it but I don't know if that's true or not.
However we use Quick Charge. Quick Charge doesn't look for resistors, it looks for the other chip inside the charger and talks with that chip, essentially doing a digital handshake before they initiate quick charging.
That prevents the charger from outputting anything higher than 5V unless the device specifically asks for it.
So, in theory, ANY data cable should be perfectly compatible with QC.
Data cable meaning that the D+ and D-, teh data, connectors are hooked up.
QC performs the digital handshake, and subsequent voltage/current adjustments, by talking across the D+ and D- conductors.
If you have a "charge only" cable or a PortaPow "data block" adapter, it means that only the V+ and V- connectors are hooked up and as a result QC chip in your 10 can't talk to the charger to negotiate the QC.
As for why some type C to type A cables don't support quick charge. I have no freaking idea.
I've got one cheap C-A USB 3.0 cable that I bought from ebay and it's a weird cable...
First time I tried charging it was in the car with a dual port (A) QC3.0 charger. Phone said slow charge, for faster results use the original charger. Didn't try again.
With the stock charger I'm testing at the moment, I first got 1.8A (after 1A>1.3A>1.8A over a minute). Unplug and plug it the other way around I got 1.7A and then it dropped to 1.4A. Third time I plugged it in the same way I plugged it the first time and now it said slow charge.. Plug it again the same way and now it charges.
Could it be that the cable either has a 10kOhm or a 22kOhm resistor in there? Maybe. Idk. Don't have means to test it right now, but I'll probably gut the cable later and measure it when I have time.
Moral of the story: come on guys, buy good quality cables from reliable brands for charging. They're not expensive.. Aukey, Anker, PortaPow, you name it. There's a lot of them out there.
I'm personally using the PortaPow cable for charging my 10, only 1 meter length available at this moment but if you want longer or shorter lengths, message them. They'll make them if there's enough interest.

Except that these guys don't make the cable that I need (or I just haven't been able to locate one).
I need a ~6-ft/2m cable with a 90-degree-to-the-front/back elbow on the USB Type C connector like the one shown here:
...and black...no goofy colors.

I thought I knew the correct cable to purchase (I only bought this phone 5 weeks ago and I need to buy 1-2 backup charging cables.
I always bought cables from Monoprice.com (for my M8 anyway) because they were decent quality, they had 6" lengths available, they were pretty cheap, and they had goofy colors (I'll take anything to break up my day a bit).
But now I am not sure which cable is correct. Is the USB version irrelevant with the HTC QuickCharge functionality? So I can get either v2.0, v2.1, or v3.0 USB-C to USB A?? Also, I will go to another vendor if need be, but most of the cables at this website do not state a resistance—just voltage and amps.
So this would be one I might get because it seems OK...

Proper means they all have 56k resistor, just like jesus said in the bible. So they are fully compatible with HTC10 and can be used with any QuickCharger or USB PD charger without risk of drawing too much power resulting in explosion. 56k resistor is the main key here and mr Benson, a Google engineer working on devices using USB PD specs which *need* a proper 56k resistor Type C cable, tests himself various cables using a hardware tester and posting reviews about good and bad cables.

Q6: Does it matter what type of charging cable is used with a Quick Charge adapter?
A: Quick Charge is designed to be connector- and current-independent. Quick Charge is designed to be compatible with a variety of formats, including:
USB Type-A
USB micro
USB Type-C
Proprietary connectors
Quick Charge high-voltage operation is designed to minimize charging issues associated with long or thin cables, allowing for a superior charging experience, independent of cable type or cable current capability.

Unfortunately you did not read the big post on this page along with the article about delivering power over usb cable.
Both QC and USB PD require cable with 56k resistor to work properly. Hence the cable for Google Pixel or HTC10 is the same. Each standard deliver power in its own way over the same cable.

"It's own way" -- correct. USB-PD requires 56k termination for legacy device compatibility. Our devices use QC, not USB-PD.

If this is true, it goes against Qualcomm's specs that I linked that you may or may not have read for comprehension. Qualcomm states that they have no/zero/nada/nicht/nill/null/zilch cable requirements for QC. Also, QC predates USB-PD. The two have nothing to do with each other.

Do you have an authoritative source that shows that the 56k terminator is necessary for QC3 to work on the htc 10?
I cannot find it on Qualcomm's site or htc's site. Google Pixel and Nexus 6P sites are not authoritative sources for the htc 10 or Qualcomm Quick Charge.

I did not accuse of anything, I am not a prosecutor.
99% of cables used to charge your and mine HTC are USB A (2.0)to USB C cables. The resistor is needed so you will not draw to much current via USB A connector which is not rated for 3A. Lower value resistor will force to draw to much from USB 2.0 spec connector and cable. Simple as that. So your digital handshake between chips is worth essentially nothing if they will indeed greet and meet over cable that is not rated to pass a 3A high current which will lead to fry something.
I suggest to read the discussion in comments section on Benson Leung G+ profile. Do not get me wrong, I wasted my time to go all over it and I do not see point to go back couple of articles again just to point a few most important comments by Benson. You could do the same, because it does not matter if you believe me or not. Bottom line is, you need a 56k resistor USB A to USB C cable for HTC10. Same cable which was shipped to you by HTC in the box. If you do not believe, then take a sharp razor and disassemble your cable. They're cheap so you will get yourself a brand new one very fast.
So, check your oem cable, ask Qualcomm and HTC via mail why you need a cable with 56k resistor. Simple as that.

99% of cables used to charge your and mine HTC are USB A (2.0)to USB C cables. The resistor is needed so you will not draw to much current via USB A connector which is not rated for 3A. Lower value resistor will force to draw to much from USB 2.0 spec connector and cable. Simple as that. So your digital handshake between chips is worth essentially nothing if they will indeed greet and meet over cable that is not rated to pass a 3A high current which will lead to fry something.

The conclusion you drew is faulty. The pull-up resistor is needed to protect legacy equipment; it has nothing to with Quick Charge or cables/connectors being "rated for 3A" (they aren't--chargers are).

I have and they are all dealing with USB charging protocols, not Quick Charge.

So, no, you do not have an authoritative source for Quick Charge cable compatibility for htc 10.
Did you read the Qualcomm link I sent? It does not require the pull-up resistor. htc FAQ only says "buy our [only one, short, overpriced] OEM cable"; htc tech support never replied to my query.

Ok, it is no use to continue this further. Everybody will do as they want and will be happy. You can recommend cables without or with any other lower resistor and I will recommend with 56k as I did before that actually are working.
Still I can wait for your cable disassembly as last proof that I am completely wrong but I think that will not change anything at all in this discussion.

USB type C cables and chargers

This will be my first usb type c device. I'm sure a lot of you are upgrading from the original pixel. Can you guys recommend cables and chargers that you have used that you liked? I'm sure there are a bunch of people in my situation it can help to stock up on this stuff before the phone comes. And yes I know there is a list of approved cables, etc.

I'd look at Anker or Aukey for chargers. They should have a couple PD-2 chargers. They also sell the required cables.
The Pixel 2 XL will come with cables and a charger in the box though.

Thanks. I know it comes with some. Just trying to figure out work, bedroom, etc.

Make sure the cables you buy have a 56k ohm resistor.

I have followed this info on cables and chargers. Great information.

How does one read posts on google +? Left to right? I have a hard time with it.

It does but you always need extra cables or chargers for travel, car or work.

Purchase via Amazon or store, whichever you prefer. It's the one that charges the phone rapidly with Power Delivery.

what do you guys think about chinese usb type c cables? any experiences?

I would never get a cheap Chinese/no name version. From what I've read, if it doesn't have a 56ohm resistor, it has damaged phones.
You can also check on Amazon and read reviews from those who have purchased. Not worth saving a few bucks to potentially damage your $900+ phone.

I've never seen a EU version. I could be wrong. You can just the US version and get a plug converter.

If its OEM, I don't think there will be any issues. I'm sure people may have multiple USB-C items and I'm sure these news outlet and reviewers have multiple USB-C cables and plugs that they just use the same one over and over.

DO not get any usb c cable/charger so many of them don't follow the standards
Only get one that has been tested
bad cables and charger in best case can charge slowly
in worst case can damage the phone or explode
follow https://plus.google.com/collection/s0Inv
and only use good cables
from the top of my head, the good ones are from
belkin - anker - CHOETECH - IOGEAR - Veckle

i hope this help most of you
i am looking for a charger with 2 usb c port ( i fond only bad ones )
if anyone finds one tell me

The car charger your linking has history of being bad.

Mark for deletion please.

As far as I can tell, Benson Leung finds issues with every Aukey product he reviews. I'm contemplating the BlitzWolf BW-S10, as I've had no issues with the BW-S5 or BW-CB3, and their reputation appears to be clean. The supplied cable is USB-C to USB-C, right?
