Not sure about QC4 , but Asus has their own car charger that seems to support at least 18W charging.
https://www.asus.com/Phone-Accessories/ASUS-Car-Charger-with-USB-C/specifications/
Any QC3 or QC4 charger will work. The difference in speed is marginal. Like one percent more every fifteen minutes with QC4 marginal.
Since on the phone side it's QC4, it can also negotiate voltages with USB-PD3 fast chargers, so any 18W or more usb power delivery adapter should charge at a good speed as well.
Don't know which that Asus charger linked would be. The voltage ranges listed could be for either QC or PD. They are identical. Either way, it would work and use fast charging.
Any standard USB-PD charger with support for 9V output will work. No need for Qualcomm's silly licensed names. Belkin makes one that I have used on many phones and tablets with various input voltages.

I received a sample unit from ChoeTech of their new 6-port 50W USB QC3.0 charging station for testing. This product has been available on Amazon since early June.
https://www.amazon.com/CHOETECH-Cha...t_2?ie=UTF8&psc=1&refRID=38JX0Y88THN4164GBCXS
This product offers 2 QC3.0 ports as well as 4 'smart charging tech' ports. The smart charging ports will variably supply amperage up to 2.4A depending on the device.
Per the device stats:
4 smart ports = 5V @ 2.4A (Max)
2 QC3.0 = 3.6V~5.5V @ 2.4A (Max), 5.6V~9V @ 2A (Max), 9.1V~12V @ 1.5A (Max)
I have been testing out several companies' QC3.0 offerings over the past few months. I have a LG G5 and have posted previously about my results on QC2 vs QC3 charging here: http://forum.xda-developers.com/lg-g5/how-to/g5-charging-data-using-qc2-0-t3358220
I now conduct my testing with USB multimeters connected directly to the charger. Despite the existence of good charging logging apps (I prefer Battery Monitor Widget Pro myself), the Android OS does not properly report amperage. I believe it is because they expect 5v input, and with Qualcomm's Quick Charge the voltage varies greatly.
Unit 1:
This one was fulfilled by Amazon. Utilizing the USB multimeter, I quickly discovered that the voltage did not fluctuate at! It started and remained at 9V, with amperage starting at 2 and slowly dropping as the charge time continued.
Basically, this behaved exactly like QC2.0 tech and not at all like QC3.0! I messaged customer support and they were quick to respond, indicating this was a defective unit. A replacement unit was sent, this one direct from China.
Unit 2:
This product did have the proper voltage and amperage responses I would expect from a QC3.0 charger.
One new issue I discovered though was that if the G5 was in the early stages of charging and the battery % was low, the charger would cut off, then restart. Careful examination showed that this would occur whenever the max wattage approached the upper limits of QC3.0 spec. (QC3.0 spec has a max wattage of 18W). It seems that when the phone requests >2.4A, the charging circuit would cut off, then restart. It does appear once it restarts once, the phone continues and finishes charging without issue. This was using the stock LG USB-C cable.
I brought this issue up with Choetech's customer/technical support. After examining the video I provided, they will be increasing the limits of the amperage circuit to 3A so that it will not cut off if the phone requests more. This updated version is currently being manufactured and I will report back with results once I receive it for testing.
from gsmarena:
We initially thought that the Rapid charging tech used by Lenovo must be Quick Charge 3.0 since the P2 uses a Qualcomm chipset. However, our third-party QC3.0 charger didn't charge the P2 particularly fast, so the jury is still out on whether Lenovo is using a proprietary charging technology.
so... my car charger and my power bank, BOTH qc 3.0 are useless with this phone??
Our charger is a basic 12V 2A charger, giving a total of 24W Power. I don't see anything special in the charger. It's probably not the usual QC we had heard of. I have seen in some reviews though about this charging technology being different and very interesting.
A problem would be: what charger for the car???
i have the phone and i can confirm it only uses the QC feature with the included CHARGER
no way to use any qc 2/3.0 charger....mmhhh bad decision lenovo!

I don't see your point. This charger outperforms any other chargers in the market even turbo and dash chargers.
Why do you ppl always end up blaming others.
because i am against the proprietary charging algorithms..... dash charge is great? NOPE.... it forces you to use a special cable, a special charger, no 3rd part suppliers... high price of chargers, is it a good move for the customer?
same thing for this lenovo charging solution, ok the fastest one, but if i lose che official charger i am stucked with the NORMAL 5v 2a solution....
this is not a great thing imho, and all power banks i have qith 7/9/12v qc features are USELESS with the lenovo p2......
You're thinking only voltage my friend, check if your power bank can supply 2A at 12V. Probably no. Mostly all power banks bottlenecks at 1.5A.
So, there isn't a way to use another charger for fast charging?

my xiaomi power bank 2 20000mah does have qc3.0 and it's tested to arrive higher than 2A at 12v ... but even if other chargers are "only" capable to reach 12v at 1,5A ... it is still a missed quick charge because p2 uses proprietary charge coding
ok this is not THEp roblem, but just a con. like for dash charge people repeat at eveyone that oneplus is the fastes... but hey without an available dach charge power bank... that phone is s "joke"
I have another QC3.0 wall charger, when i plug to P2 it's out put at 2A only not fast charge.
But when i plug original charger from P2 to another phone fsst charge status is become.
???
How many times will you open new topic for the same problem ?

Hey!
I noticed recently that my G5 charges quite slow. So I tested all of my powerbanks, cables, and wall chargers, in various combinations. I had 4 different powerbanks, 3 wall chargers, and 4 cables.
I used a USB ammeter to measure the power draw going through the USB cable.
On the motorola charger and cable that came with the phone, it charges at 1.8a. I then charged my phone from each powerbank and wall charger, using each cable in turn. The average charge speed for my phone was about 0.5a. Out of 28 combinations, only 2 yielded a draw over 1a.
I have created a spreadsheet detailing the charge speeds of each combination, but unfortunately cannot post it yet (10 post permissions).
I then charged my USB powerbanks from the same wall chargers, using the same cables. One powerbank charged at over 1a with every combination, and reached over 2a on numerous combinations. This proves that the cables and wall chargers are not at fault, it is a phone issue.
Why? Has motorola put something in their chargers that 'talks' to the phone, and allows for faster charge speeds? 0.5a is awful!
Secondly, does anyone know of cables that I can buy, which will support fast charging for the motorola? I have looked at genuine motorola cables, but there is no way to tell one from the other.
Thanks!
Paul
P.s. charge speeds were the same, whether the phone was switched on or off.
Welcome @agour
I've come up to a similar conclusion with a lot less data (thus I didn't share them).
I caught power consumption at the wall outlet when charging my device with two chargers: Motorola stock charger and a Samsung Adaptive Fast Charger.
The Samsung has the following specs: 5V 2A or 9V 1.67A with fastcharging capable device.
Using Samsung Adaptive fast charger and Samsung 1.5m cable : 6W, so the device charges at something like 5V 1.2A...
Using Samsung Adaptive fast charger and the cable provided with my XT1676 : 11.3W (which is coherent with the max 9V 1.6A, and would mean the charger provides 2.2A if at 5V which more than the specs.)
Using stock charger and stock supplied cable : 11.3W ==> fast charge for similar reasons as above
Using stock charger and Samsung 1.5m cable : around 6W ==> low power charge
I'd need a USB multimeter to confirm those data. (mostly due to the variable voltage that can provide fast charge adatpers)

Interesting! It's suprising how much difference the combinations can make.
I don't think I have experienced this on a phone before, however I have never felt the need to test it...
I tested the original cable that came with the phone, and an off the shelf 'genuine motorola cable'. The stock cable is still the fastest, however the secondary cable still worked very well.
Interestingly, one of my powerbanks will charge at 2.2a from pretty much EVERY powersource and cable combination. This is with 7 cables tested, and 3 USB wall adapters.
Shame that motorola doesn't allow their phones to draw maximum power from hardware that can provide it..

If I have some time, I may test internal impedance of the cables, it is possible that the device somehow probes the cable (or the cable + charger) and then decides if it can or not draw that much power without overheating/melting the cable; and then it will negotiate the quickCharge with the charger.
there has been a discussion about quick charge on this thread a while ago (before I got this devices : https://forum.xda-developers.com/g5/help/quick-charge-3-0-support-t3632457)
Lenovo adds the following that I have not tested:

It is quite obvious that especially cheap cables will charge phones much slower as the resistance is too high, even if the phone does not perform any checks. Those cables are basically too thin. Resistance limits the current (amps) that can flow. Newer phones most likely just look at the charge current during the first x seconds (or less) and then decide wether to enable fast charging or not to keep the cable from heating up. A wire with high resistance is basically a heater. So it's a necessary safety feature (from the companies POV).
Regarding the power bank, it may be possible that this particular design provides a voltage slightly higher than the nominal 5 volts (still fine for most devices), which helps overcome the resistance. That is also the reason why the Samsung fast charger provides 9V: You don't need a cable as thick as with 5V.
Keep in mind that the USB specifications only recently got updated for such high charging currents, so it is advisable to use only the cable that comes with the phone as USB cables in general don't need to provide such high currents by spec!

That sounds correct, although my Samsung wall adapter is fast charge capable, and was provided with a cable (and not a cheap one), that basically can't be use for fast charging with the G5, that looks silly...
I am looking to purchase an extra 18W charger, North American variant.
Is it available for purchase anywhere?
The only 18W charger I could find on Asus' store mentions being a notebook charger.
But it appears to be identical.
Having used OnePlus phones, I do miss how easy it was to purchase accessories on their website...
Thanks
Any QC3/QC4 charger will be ok.

Whats. The difference in quick charge 3 and 4 as far as speeds? The 5z had a 18w qc3 charger and the Zenfone 6 has a 18w qc4 charger..would the qc3 charge slower ?

I guess the original charger will be faster. Can you try and compare it?
I compared the two.
Note, that, presumably, because the OEM charger does not go up the maximum 20V of QC4 (only 9V) it is not actually a certified QC4 charger, despite using the standard.
Also, the power rating for QC4 isn't actually higher than QC3, it merely has finer voltage control, allowing for better efficiency.
Sidenote, funnily enough, my QC3 charger is two thirds the size of the ASUS downgraded QC4 charger...
I used ampere to measure current at 50% charge.
That said, I used a QC3 charger from my previous Mi Max 2, it definitely got picked up by the Zenfone 6, showing the two plusses in the battery icon. It reached a max current of 2.5A
The OEM charger reached a stable 3A.
A difference is certainly there, but my guess is it won't actually be THAT significant in the real world. Personally I always use two chargers, the OEM for fast topping up, when needed. And another really "crappy" (0.8A smartwatch charger) for overnight charging so that the majority of the charging I do stresses the battery as little as possible. No matter what Qualcomm likes to tell you, fast charging definitely shortens the lifespan of a battery, so while convenient, it's good to do it as little as possible.
If you REALLY want the fastest possible results, try and find a QC4 charger. Only a few actually exist to buy right now.
Otherwise you can get a QC3 charger, there are TONS of those, and you can actually get the pretty cheap too. You'll only lose 0.5A anyway.
You could probably also use a USB PD 3.0 charger, as QC4 is able to negotiate voltages with it as if it were a fully supported QC charger.
Edit. Tried charging with both from 55% to 71% (It just happened to be where I was at with one charger, then used a battery drainer to do the exact same charge).
The QC3 charger was one minute slower at 16 minutes, while the OEM did it in 15 minutes.
Which chargers other than the original stock and the Spigen one will charge the Pixel 6 Pro at full 30w?
I see there are 30w from Anker and even Amazon Basic, would these charge at full speed?
You just need a PD 3.0 (or higher version) compatible charger that can do 30w or more. The rest matters not, it's an industrial standard.

Part of me wants to be fancy and get the pixel stand 2nd gen, but in all honesty I don't think I'm that fussed about having all the exclusive features like gallery showing pictures etc so to be fair I may just get a standard wireless charger, but even then I'm not that fussed charging it wirelessly, I think I just like the concept of standing it up lol

Will these chargers work at 30w on the Pixel? I have a ton of these at this point, including a car charger. Would be cool if they worked correctly at full speed.
I bought an extra (already got one) original 45W charger. I know it's overkill and a rip off, but whatever. At least it will charge just about anything USB Type-C, right?

Don't know yet, but hopefully we can test it out soon...
30W and 50W WARP wireless charging is only for OnePlus phones. The OnePlus 30W wireless charger does max. Qi charge at 10W, and the OnePlus 50W wireless charger does max. Qi charge at 15W.
The Pixel phones are locked at max. Qi charge of 12W with any wireless charger other than Google's wireless charger.
That's no where near the 23W capability from Google wireless charger.
See here: https://9to5google.com/2021/10/19/pixel-6-tidbits-plastic-top-wireless-charging/
Edit: I think I misread someone's question...my post was only directed towards wireless charging.
I believe Samsung chargers use the PD standard and should deliver a fast charge.
Any PD charger of at least 30W will give you the max charge speed. I doubt there will be a big difference using the 18W Pixel chargers from older phones. I'll be using a 10W wireless charging pad I got on Amazon a couple years ago that is connected to an 18W Pixel charger. It will charge overnight so how long it takes doesn't matter. I use this charger for my Pixelbook. It has 2 PD ports and a usb-a port. It will work for the new Pixels and does super fast charging for the new Samsung phones. A phone will only draw as much power as it is rated for so the 65W rating won't hurt your phone. It would charge 2 Pixel 6's at the same time at 30W.

I can't confirm, but I'm 99% sure they will not charge at 30w. OnePlus does 5V at 6A to get 30W. This is not a PD standard. At best you'll get 5V3A so 15W.

I have this charger https://zendure.com/products/superport-s3 it's a dual PD 65W charger and it still charges my Pixel6P at a ridiculously slow pace. Even with adaptive charging off. It's also a USB 3.0 charger that charges all my other devices very fast except for my P6P so there has to be something more to it IMHO.
EDIT: According to this article https://www.androidauthority.com/best-google-pixel-6-chargers-3041818/ There are 3 standards required USB 3.0, PD and PPS mine doesn't appear to have the latter so maybe that's why.
It can't be any PD 3.0. It has to support PPS protocol. Most charges that don't explicitly state that they support are not good (for P6/P6P 30W charging). For example this anker one is PD3.0 PPS one.

This is the right answer.
Make sure it supports PPS.
I got a GaN one with PPS support up to 65W for 30€ on Amazon.
It's nice the pixel 6 tells you whether your connection is a fast or slow charge. I picked up a $16 PD PPS charger at AMZN and the P6P shows it is fast charging. The AMZN listing showed it as iphone 13 series compatible but no mention of the Pixel 6 line.

Because to some people only Apple exists and marketing material MUST mention Apple. All other OEMs are an afterthought.
Luckily, all other OEMs also aren't Apple, hence they tend to prefer standards over proprietary crap, so 99% of the time you can assume that accessories will work anyway.
