QC Chargers

I have a QC 2.0 charger that worked fine with my Note 4 (2A) and Note 3 (only 1A), but doesn't charge my axon. It seems to be a protocol negotiation issue. Right when you plug it in, it says 1.5A, 1A, etc.. then after 30 seconds or so, it goes to discharging.
Has anyone tried their phones with other QC chargers (not the stock one that comes with the phone)?

The Axon 7 is QC 3.0, so maybe that's the issue?
My old non-QC charger work just fine with my Axon 7 (though of course they're not as fast).

I also have a quick charge 2.0 charger that doesn't work with my USB type c cables. However when I use a micro USB cable with an adapter it works fine so maybe give that a try.

Anyone recommend any QC 3.0 chargers? I would like an extra one for travelling and maybe one for the car.

tried with the ZTE cable coming with the phone, but just received a spare USB3->USB-C always from Aukey to use in the car.
ZTE cable working fine, i still have to try the Aukey cable though (https://www.amazon.it/gp/product/B0196GHUEM)

I have this car charger as well, along with this usb C cable, at least according to Amazon, but it looks nothing like this, maybe it got updated.

This cable doesn't *advertise* using a 56k resistor. I'd stay away from it unless clarified.

Does this one seem OK?

It seems to be working just fine. However, the built-in cable might seem like a bonus but it's not such a good idea... It will be the first part to break (as always with attached cables) and you charger will loose its value.
I'D consider this instead. Same price but you need an USB type C cord (this pack is awesome). I own both these articles and i don't regret buying them one second .

Sorry, I can't post links since I'm a new XDA user...
I've bought on Aliexpress a Choetech wall charger (ASIN B01D9QZV28) and a Choetech car charger (ASIN B01582ELMC).
They work great with the supplied ZTE USB-C cable and a Choetech USB-C Cable.

Thank you for the suggestions. You know, it just occurred to me that my car (2016 Mazda CX-5) lacks a 12v "cigarette" style outlet up front. I have two always on dedicated USB charging ports in my arm-rest. Those ports are not quick charge ports though. I have two other USB ports up front where the 12v socket is usually located and these are standard USB for the infotainment setup. Hum.... The phone will charge OK on a standard USB to C cord right that lacks QC 3? Bummer. Was thinking I could get QC in the car but not likely! I will need the suggested cables either way though.
I may have a 12v in the armrest too, but same deal - I'll need longer cords.

If it's standard USB A ports, the phone will charge at a normal rate, just not at QC rate.
That's what i like about those cables. 1 is really short (~30cm/1ft) one is very long (~2m/6ft) and the rest are a standart length (~1m/3ft). They all provide USB 3.0 and QC 3.0 support.

Ordered! Thanks again.

At home, I use the quick charger and the USB cable that came with the phone as well as a Insignia 10 ft. USB-C to USB 2.0 cable with Insignia USB AC adapter.
In my car and on the go I use a Platinum QC 2.0 car adapter (http://www.bestbuy.com/site/platinum-quick-charge-car-charger-black/1638009.p) and AC adapter (http://www.bestbuy.com/site/platinum-quick-charge-wall-charger-black/1637019.p) with VCE cables (https://www.amazon.com/VCE-3-3FT-6-6FT-OnePlus-950-3PACK/dp/B01J0VVKEY). The cables are Benson-approved and USB 3.0 for a really good price.

I keep my old Samsung quick charge brick (from my Note 4) and a USB type-c cable from my OnePlus 2 in my bag for when I'm out and they work just fine for quick charging. Not as fast as the ZTE cable/brick combo, but pretty close.

No quickcharge usb-c to usb-a ?

Tried a bunch of different Anker quick charge 2.0and 3.0 chargers, samsung charger, and tronsmart qc2.0 charger and it does not seem to want to quickcharge. (all usbc to usba)
Is it only possible to QC over usbc to usbc?

The pixel doesn't support Qualcomm quick charge.

As mentioned it does not support QC, and yes, the fast charging will only work via Type C. And the 9V/2A charge only works with power delivery enabled chargers.

Thanks for the info . Oh well. Still charges pretty fast on normal chargers.

Can a Quick Charge 3.0 charger be used with the Pixel 2 XL?

Hi,
I have several car chargers that use Quick Charge 3.0. Would it be safe to charge the new Pixel 2 XL with those chargers, and would it provide fast charge?
Thanks!

It will charge but not at the same rate as the stock charger 9v/2a. It will slow charger the pixel fine assuming your charger is good and you are using a good Usb-a to usb-c cable.
Quick charge is a qualcomm proprietary charging method that the pixel doesn't use. If you want fast charging I would suggest finding a usb-if certified usb-c charger that does 9v/2a. Obviously, the one on the Google store that comes with the pixel should work.
One word of caution. If you follow Benson Leung and Nathan K. on Google+, you will see there are a ton of out-of-spec usb c chargers and cables on the market. That is why I suggest that you buy one that is usb-if certified. That should offer you some level of safety (though not always, I'm looking at you belkin and your 27w car charger with power delivery)

Just go for any chargers with Power delivery, it will work.

Yup. It's my understanding anything that goes from USB-A to USB-C, regardless of what kind of charger it is, will always charge at 1A or less.
Also make sure if you "have" to charge USB-A to USB-C, you don't use a "bad" cable. (see Bensen reviews)

My understanding is that you are referring to a cable that is wired for both data and charge. I have several "charge only" A to C cables that are wired different from data / charge cables. These charge my XL quite rapidly.

I believe quick charge 4.0 all also supports power delivery. But, I haven't found a 4.0 charger.

I have been using all my Quick Charge 2 and 3 chargers and the work well.
They don't charge as fast as they did with my Nexus 6, but they are far from slow charging.
I am using these adapters on all my cables and they awesome.

Looking for the Quick Charge 3.0 charger for Google Pixel 2 XL ? I am just now using Choetech for my Google Pixel XL . It have an ability to Quick Charge 3.0 and USB Type-C ports. So, you can charge different phablets like Google Pixel 2 and Pixel 2 XL which are compatible with these ports.

Multi-port Charger options (e.g. Anker, RavPower)

Seriously considering this phone, but there are a few aspects that are putting me off, one of those being the proprietary charge protocol.
With so many devices in the house, I currently have a 5 port Anker desk charger, and really don't want to be restricted to the Huawei charger to get anything better than "slow charging".
Has anyone tested charging using a third party multi-port desk charger and found fast charge 2A charge working? Has anyone tried USB PD via a USB-C port?
Also, please share experience of third party multi-port chargers that will NOT supply 2A charging so that we can rule out models.

I'm currently using choetech 3 ports wall charger. Maximum it could provide is 1.8A. Not quite as fast but fully charged within 2 hours. Good enough for me.

Does the charger provide the full 1.8A charge? You can check using this app - https://play.google.com/store/apps/details?id=com.gombosdev.ampere

Yes, that's how I know it's charging at 1.8A. But I don't really check the charge when it reaches something like 70-80%.

Not Fast Charging in Car

So I have 2 Aukey QC 3.0 fast charging adapters for my car, however, neither work for the S10+. It either says slowly charging or charging. These adapters work fine with my S8+ so what gives? Did Samsung start blocking third party chargers or something, I've tried the factory USB C cable as well, so it's not that. Also, I use an Aukey QC 3.0 adapter at home which works perfectly fine, so I'm not sure if Samsung is only blocking 3rd party car adapters.
If anyone has a working fast charging adapter for their car, would you mind posting a link if its available on amazon? thanks

All of my current home and car chargers for the S9+ are working as fast chargers, might not be as fast as fast charge 2.0.

Has your car ever fast charged any phone?
Most cars simply fail at delivering that much power, fast charger or not

Yes, like I said, it works for my S8+. I have another adapter which is iRAG branded, that one works fine, so I guess I'll just re-order that one, if anyone is interested, it's this one:

Surprising that the Aukey branded one doesn't work considering the S10+ still uses Qualcomm's Quick Charge 2.0, which is as old as the S6

Samsung S10 series doesn't use Qualcomm quick charge 2.0 rather its Samsung fast charge 2.0. There are a lot of confusion regarding QC 2.0, 3.0 to FC 2.0

Download Ampere from the play store, everything over 1600 mAh Is considered "fast charging".
You'll have more luck with generic fast chargers such as some made by Anker or your previous one instead of those marketed for QC 3.0.
My own wall QC 3.0 fails to charge over 1a, it doesn't even fall back to standard charge or QC 2, which would be around 1.5a+, meanwhile my Samsung charger and Anker Power core 2 do 2.2a+ just fine, there is clearly lack of compatibility with Qualcomm's protocol.
