Quick Charge 3.0 & "Charging rapidly"

So I've now purchased a wall charger and a car charger that both have QC 3.0 and claim to support the HTC 10, but neither of them show the "Charging rapidly" when charging my device. Only when I use the original charger or an external battery with QC 3.0 does it display that. Is it possible that it's still charging using QC 3.0 while charging if it doesn't display the "Charging rapidly" on the lock screen? I really just want a car charger and additional wall charger with multiple ports that will rapidly charge my HTC 10. I'm really sick of buying accessories that do not when they say they support the HTC 10.
These are the accessories I've tried and none of them will display "Charging rapidly":

Any ideas?

THIS is a good multi port charger I have one and it quick charges and displays on the phone it is. I use this cable on it.
For a car charger I use THIS and it quick charges no problem with THIS cable

I am wondering the same thing... what does a cable or charger need to provide fast charging... I wonder if it's the cables because I got one from amazon and use it with the htc charger that came with the phone and it does not "quick charge," it only does it with the cable it came with. I bought this one:

I just made sure they were the latest cables, the ones you linked to are USB 2.0 and 480mbps. while I made sure to get USB 3.1 to USB 3.0 cables and have 5gbps. I know the speeds really don't have much to do with charging say, but I think the generation of cable has a lot to do with it

Hmmm.... good point, if someone could confirm this maybe? Does make much more sense, I guess I should've read better. I will just get one of your cables because I just recently bought a QC 3.0 car charger and there's no point in it if it ain't fast charging.

So the Aukey multi-port charger came with a USB-C cable and it claims to support the HTC 10, so it's infuriating that it doesn't work.

I use this wall charger and it shows "charging rapidly" on the screen. I have an older cable with the micro usb connection, so I use this adapter to make the connection to the phone. Combined, they work like a charm.

Are you using a USB-C to USB-C cable? those accessories only have quick charging on the USB-C port. If you buy new ones make sure to check what ports support the QC 3.0. Sometimes the only have one port that has the QC and the rest are normal 2 amp ports.

I've just ordered the Aukey 6 port USB Quick Charge 3.0 Wall Charging Station from Amazon UK (link below), so I'll test it once it comes in and post here with the results. One thing I noticed is that the Aukey hub only supports QC3.0 on the USB-C plugs, not the USB2 ports. I'll be using this to charge my HTC 10 and my Pixel C using the USB-C ports and USB-C cables for both devices so I can see if both QC3.0 AND USB-C Rapid Charging works at the same time. The remaining USB2 ports I'll use to plug my Qi charging pads into and my smartwatch charger. Looking forward to not having so many plugs lying around.

I'll let you all know once it all comes.

Okay, so I just got delivery for all my bits in my previous post. I've made sure both my HTC 10 and my Google Pixel C ran down the battery to 20% on each and plugged them both into the USB-C ports on the Aukey charging station using USB-C to USB-C 3.1 cables, both 3 foot long. I'm not using any of the cables that came with my tablet or phone or the USB-C 2.0 cable that comes with the Aukey charging station, I am using Belkin USB-C to USB-C 3.1 cables.
Using the Belkin USB-C 3.1 cables both my HTC 10 and Pixel C show Charging Rapidly after around 45 seconds on the lock screen with a time remaining counter.
Using the Aukey USB-C 2.0 cable that came with the Aukey charging station I do not get Charging Rapidly at all on my HTC 10, I only get "Charging" and a percentage.
However, I do get Charging Rapidly with time remaining counter on my Pixel C when using the Aukey USB-C 2.0 cable.
Based purely on my own testing, I would make sure you use high quality cables, preferably the 3.1 gen cables and then nothing will be slow. I have no idea why the USB-C 2.0 cable doesn't like to Quick Charge my HTC 10, and I don't have any other gen 2.0 USB-C cables to try out, so sorry about that.
I hope that helps some of you out.

Mine does not show Charging Rapidly even though I use HTC supplied charger and cable! Do I need to activate it or what? I am using and EU plug converter to my US charger, might that be the problem, although I doubt it just passes on the same supply, its not a frequency/voltage converter.
Thank you for your help!

I'll check tonight and let you know later, but I'm pretty sure that the charger that comes the HTC 10 in the box is NOT a Quick Charge 3.0 Rapid Charger... Which would explain why you are not seeing "Charging Rapidly" with the original charger and USB cable. I may be wrong, but I will let you know either way in this thread as it is honestly something that I did not look at when I got my phone. Mine is a UK model bought in-store in the UK so what you get in the box may vary depending on the region you purchased from.
Cheers

The supplied HTC charger and cable are QC 3.0 compatible. They show "Charging rapidly" when I connect my phone.

The iClever 24w QC 3.0 charger works with the orange-e 3.1 usb c. It displays "chargin rapidly". This is probably unrelated, but the charger doesn't show it as chargin rapidly, but the phone does.

The supplied charger is definitely a quick charge 3.0 charger, it even says it on the power brick. It doesn't matter what region you are in, all of them come with a quick charge 3.0 charger.

Yup, you are correct. Just got home and plugged my charger in and it too shows "Charging Rapidly". COol, now I have a backup in case my Aukey stops working for whatever reason.
@fidanhGPE I'm not sure why yours doesn't show as Charging Rapidly when using your original charger, possibly something wrong with your handset maybe? Sorry I can't be of more help to you as all mine works fine with the original HTC supplied charger and HTC USB-A to USB-C charging cable, and also with the Aukey charging station and a USB-C to USB-C Gen 3.1 cable.

Having a Nexus 6P, I was under the impression "rapid charging" only worked with a type-c to type-c charger..?

It might be the converter because you should get "Charging rapidly" when using the charger and cable that came with the phone (that is still weird though), and yes they are Quick Charge 3.0 compatible like the other person mentioned above.

I checked it, it QC 3.0 and it is charging rapidly, though I get it only on the power/battery settings only, no notification when I plug it in.
On another note, do you know if I can use old (normal) car chargers on HTC 10? Will it charge the phone, although I am not expecting a quick charge there? Will it harm the phone?

Nah man just make sure you have a type a to type C usb cable that has that 56ohm resistor crap to make sure your phone will be fine. Phone will charge just fine. I actually just got a QC 3.0 car charger as well and it doesn't charge THAT much faster than an old car charger I had.

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.

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.

Which Charging cord is the best?

Hello, I just purchased a Pixel 2 and wanted to buy a 6' cord that I can use with the fast charge. I was looking at Anker because I use them for my Nexus 6 and they work well BUT I read reviews on Amazon and I cant find one thst will fast charge. A second question is i wanted a extra brick and plug for car and I wsnted the USB ends... Thoughts?

You'll need a USB-C to USB-C cable that supports Power Delivery (PD) to connect to and fast charge with the original Pixel 2 charger.
I have these which fast charge properly: https://www.amazon.com/gp/product/B0756QGTVQ
For a car charger, I use this Meagoes charger which also properly supports PD: https://www.amazon.com/gp/product/B076H7X8QN
The same cables as above also work properly with it, or if you prefer a shorter cable (3 ft): https://www.amazon.com/gp/product/B01L0F6AJI
For an extra wall charger, Anker has this which also fast charges properly: https://www.amazon.com/gp/product/B06Y427WT7

I second this, have the same cables and just bought a second pack since they're on sale. They have the 56k Ohm resistor built-in for protection as well (from what I've read this is key to not frying your battery on usb-c/quick charge devices).

Well I've been using on my P2 for several months. I obey the Li-ion 20-80% charging suggestions by Battery University and using these cables it charges in about 45 minutes for this battery percent range. So their spec may be true but that charge is more than fast enough for me. To each their own ¯\_(ツ)_/¯

Most excellent!

I have two extra cables, one from Anker and one from the AT&T store's tech dept, both USB C to USB A. After 15 or so months, I noticed that my USB C to USB C cable no longer securely fits into the Pixel 2's USB C port. As a result, sometimes I plug in but there is no connection, i.e. no charging. The problem has spread to my Anker USB C to USB A cable. For several months I barely used the USB C to USB A cables. I requested an RMA for the Pixel 2 and the original USB C to USB C cable securely plugs into the new device suggesting the original Pixel 2's port is mysteriously damaged. Sharing this experience in case anyone else is going through or has gone through this.

The cable doesn't make much difference as long as it meets USB-C standards. The limitation is the charger; even then, I believe the Pixel 2 will fast charge at 18w, not 30.

I've noticed the USB port gets clogged with gunk over time. Use something thin like a plastic pick and gently scrape it out. If you can get tiny swabs, use isopropyl alcohol to clean it a little better. This solved my charging problems.

Gemini PDA picky about USB-C chargers?

My Google Pixel or ASUS chromebook chargers don't seem to work unless the pda is off. I'm disappointed that this device didn't implement USB-PD and that I can't charge from either side. What's the point of a standard connector if you need a proprietary power brick. MediaTek Pump Express was a poor choice.

I agree. So plugging into your charger when the Gemini is off WILL charge it?
I have a USB-C charger in my truck, and I will say that when my Gemini is plugged in it will hold the charge at whatever level it's at. It won't charge it, but at least power won't be depleted. Still disappointing, for sure.

Yes, if my Gemini PDA is off-off, my Google Pixel USB charger does seem to charge it. I don't have any numbers, but I doubt it's using the higher voltage modes so it's probably a slow charge. The red charging light comes on after maybe a second. Same poor behavior using an Anker PowerCore+ 26800 USB-PD with J5 Create JUCX01 USB-C to USB-C cables (an expensive but highly regarded cable supporting 100W power delivery AND 10 Gbps transfers). My car's AOLIEKS 48W USB-C USB-PD cigarette lighter port adapter is also useless for the gemini PDA when using the 30 W USB-PD port with a JUCX01 cable. I'll try using the QC 3.0 USB-A port with Gemini-provided USB cable tonight.
None of my standard USB-C chargers seem to do anything at all when the Gemini PDA is on. As though the cable isn't even detected. This indicates a firmware issue in the charge controller, IMHO. I looked closely at the Gemini-provided USB cables and the USB-C plug seems maybe 0.5mm longer than my other USB-C cables, so maybe it's a physical thing but I doubt it.

I was adding a 6-outlet wall tap to the outlet near my bedside table today, and while consolidating chargers I plugged the Gemini's USB-C cable into the AUKEY 12W Dual Port Home Travel USB Wall Charger Adapter - Black charger I have. It charges the Gemini, whether it's on or off. Not sure about voltages or numbers either, but the Battery page in settings showed "Charging by AC" and the time remaining seemed pretty short.

There does seem to be some magic sauce with the included USB cable. Using that cable worked fine with my power bank, but not my car charger.

I've done some testing using a Pluggable USB-C meter (can't post links due to being new, it's on amazon).
Charging is only on the left port. (More on that later.)
Using the supplied charger + cable I get 8.8v at 1.35A (close to the 9v the charger has printed on the back, charger says it supports 12v according to the back but I guess the Gemini doesn't).
Using an Anker PowerPort+ (60w, one type-c and USB A ports) I get:
- Anker USB A to C cable: 5v (well, 4.78v), 1.8A
- Anker USB-C to C cable: Nothing. :/ (the pluggable adapter doesn't even turn on, presumably not seeing any negotiation to even turn on).
Also tried a few other USB C cables and power supplies (Apple, Chromebook) and they don't charge it or pass power.
While the left port is the only one that will charge, the Gemini will take power on the right hand port -- the amount varying by usage it seems (I've seen between 0.15A and 0.41A when worked hard), so presumably it is possible to take power from a hub which should mean the device stays alive for longer but won't charge.
I hope it's possible to add proper PD / type C charging in a software update, for me a huge advantage of type C is not needing to have different adapters for fast charging... (I'm a little confused because pump express claims to support USB PD on mediatek. c o m / features/pump-express (sorry mangled url because I can't post them...), not sure what that means in non-marketing speak as it obviously doesn't work).
Forgot to test with it turned entirely off:
- It does charge off the Anker USB-C charger via C-to-C cable, but only at 4.96v, 0.38A, i.e. you're going to be waiting a while for a charge. Makes me hopeful this is a software thing though.

Replying to myself, but thought this was useful to point out:

...which does lead to an interesting trick:
Turn it off, plug it to the type C charger, then it will continue charging at a low rate while on. Could be useful if you forget the right charger (which is totally something I see myself doing).

USB-C charging is a compatibility mess, and yes, it seems Gemini PDA is on the bad end of it. I have various
But I had an LG phone that couldn't reliably charge from a MacBook Pro USB-C power supply--and it seems that charger can't charge my Gemini at all. Two rather mainstream companies that can't manage to implement a standard and make it work right, Gemini can't make it work at all, isn't unique in having problems, but clearly on the bad end...
Sounds like the USB-C standard is badly designed.

Car Charger and USB Cable Options?

Just received my Pixel 3 XL yesterday and I didn't really think about the ramifications of it being USB-C. I don't have a single USB-C accessory so I have to replace my car charger. In addition to that, the USB-C cable that came with the device isn't long enough to reach from the floor to my bedside table, much less my hands while I'm in bed so I need a replacement for that too. Also have no way of connecting it to my PC at the moment so I need that too.
So I was reading up on the way the Pixel 3 charging works, and it looks like it uses the "Power Delivery" standard and tops out at 18w on chargers only made by google, is that correct?
If that's the case, what do we do in the case of a car charger, since they don't make one?
Can we use any USB-C to USB-C cable with the original wall charger and not have brand related charging issues?
Do I need a USB-3.1 spec USB-C to USB-A cable for full speed file transfers to my PC?
Not interested in wireless charging, just need the cheapest, fastest possible options.
Thanks everyone!

Over in the Accessories forum you will see a thread on car chargers.
Meagoes and Aukey both have car chargers with PD connections. The Meagoes kit includes a USB-C to USB-C cable. I prefer the Aukey car adapter with my own USB-C to USB-C cable because it does not have the bright LED which I found distracting.

Ahhh I didn't scroll down far enough... Accessory forums used to be near the top of the list so when I got to the development forums I assumed XDA phased accessory forums out, haha. Oh well.
I appreciate the advice, I'm getting the Meagoes because of the price, and because I installed an aux port inside my dashboard for car chargers because I hate the lights on them too.
