Is there a video comparison of the charge rate/speed difference between the 27w VS 18w Charging? Something like a lab test where the phone is actually wrung dry of battery juice, and then charged from empty battery to 100% using the stock 18w charger. And doing the same thing but the second time, using a 27w charger.

So once the disappointment of my spank new nexus 5x not being qualcomm quick charge 2.0 compatible (I found this out yesterday) after buying new chargers and batteries (portable charger thingamagigs) had subsided I was pleasantly surprised that many of my battery packs were actually charging at what the nexus 5x calls 'rapidly charging'.
So far I can report that these chargers tell me they are rapidly charging:
Aukey 54W 5 port qualcomm quick charge 2.0 wall charger says rapidly charging from both the qc qc 2.0 port and the other ones too.
Anker 2nd Gen astro 6400mah battery says rapidly charging
Anker 2nd Gen astro e5 16000mah battery says rapidly charging
Aukey 10000mah qcqc2.0 (pb-t1) doesn't seem to do anything? Doesn't charge it at all works on the original n5 (without qc obviously). But I find this very odd? I was wrong it does indeed report rapidly charging
How is everyone else getting on with your portable power?
My guess is even though you are getting the rapidly charging rating, you are likely getting 2a of the possible 3a max charging amps. It means a good handshake for fast charge is occuring even if the source of the charge is incapable of 3a.
Here is a good article explaining it: http://www.droid-life.com/2015/10/19/nexus-6p-nexus-5x-quick-charge/
I assume we should soon see actual 5v 3a charging devices come out to market.
I've replied on a different thread. You should use the app Ampere and compare numbers to the stock wall charger.

Hello,
i've bought a Xiaomi Charger Set ( amazon.es) to use the 27W charger for faster wired charging.
So i'm pretty sure it is original and it says Turbo charging on lockscreen..
It charges with up to ~4000mAh when i just plugged it in, but drops after a few minutes to common "QC3 currents".
I stopped the time with the boxed QC3 charger from 11% to 75% and with the QC4+ (27W) charger from 11% to 75% and it was not a minute faster (same with a QC4+ Belkin Car Charger).
Did you stop the time and checked if it actually charged faster for you?
Yes its way faster than 18w charger
Dont relay on ampere app its not real
I have also tested my 27w charger, even posted pics on another thread, and it does charge faster. Also, I don't think I'm going crazy when I say this, but my battery seems to last noticeably longer.
Maybe this could just be a placebo or because I updated to 9.8.1 since then.
Are there any other devices with the same power output? I have various Oneplus chargers, and a couple of Quick charge 3.0, but would like a spare fast charger.

You can buy the xiaomi 27W QC4 charger it does 27-35W
realme x2 pro has 50W, so something there shud fit
I've tried various chargers but the SOC was >85% so it wasn't a proper test. With most charger (QC or PD) I've gotten 15W, including with my 65W PD laptop charger. With the original charger I got 20-22W. If it's important to check the power, I can wait until it's discharged and redo the tests, which I plan to do anyway.
For travelling, I find it a lot more useful to have the 36W (18W QC + 18W PD?) cheap Amazon charger with 2xUSB-A and 1xUSB-C, which has the same size as the original charger: https://smile.amazon.de/gp/product/B07WFDTJFR/
Let us know how you get on. I tried my Samsung 25w charger, Pixel 3 charger and the Motorola 18w charger. All of them charge at 12-18w only. Stock charger goes to around 27w
I've now tried all the chargers and powerbanks that I have, QC3 or PD. All of them cap out at 16W, even though they can deliver more. I got the original one to charge with 30W (at 60% SOC).
The original charger is marked QC3 but they are probably not following the standard.
From my understanding the Snapdragon 732g has Quick Charge 4+ support doesn't it ?

Yes, i've noticed the same. Around 27w max. Today i was charging my phone and observing the batt temperature. Kinda obvious, but the hotter the battery gets, the lower charging power it will deliver. Here in Brazil the temp this week is being around 36-42°C, so i put the phone over a bar of artificial ice. As the batt temp went under 35°C, the resultant "charging current" went to around 5500-6000mA. Doing the math, it was possible to arrive at the 27w result. (~4,5V x 6 = 27w).
When the batt temp was near 38~39°C, charging was down to 2000-2800mA (resulting to around 10-12w).
I also found something strange, it wasn't able to show the charging percentage with 2 decimals, as shown in this video:

Can someone give me a link for a u.s. charger for poco x3 device??

For me GAN 65W chargers (Baseus) are good and universal quick chargers.
I have made a quick test in the thread Chargers and Charging speed
Hi to all,
Can we charge S21U with 40W chargers? They are a lot chargers like Huawei, Xiaomi and etc... with 40W and more.
I believe the answer is yes - or at least probably. Most of those newer chargers are "Smart" in that they only provide the volts and amps that are needed by the device being charged. I may be wrong about that, but I don't think so - I don't think you have anything to worry about.

Pretty sure you can, I use a 45 watt "smart" charger on my NOTE 20 Ultra without any issue.
You can use any charger that supports PD (power delivery), AFC or QC2.0
Any 45 watt USBC charger out there is going to be PD standard so you'll be fine.
The downside is, it'll still only charge at 25 watts.
I am charging my s21U with an 40w charger, works without problem. not using 40 watts of course, but its working.
The phone, all phones in fact, will ONLY charge at it's highest speed the phone allows itself to receive, the charger doesn't matter, it can be lower or higher than what the device is recommended for. A lower power charger will just take longer to charge the phone, a higher power charger will just not charge at it's full power if the phone won't accept the full power from the charger.
I've been using the 90w charger from my HP Spectre X360 my S20 Ultra since I got it without a single issue, I still get about 2 days of use per charge on that thing, and now I've been using the same laptop charger on the S21 Ultra and it works just fine.
The phone fast charges normally, doesn't get super hot, works just fine, and I only need to keep laptop chargers around the house, it's great haha
I have a 45W USB-C PD port as part of an Anker PowerPort and also the 18W charger that came with my Pixel 5. Would I notice much of an improvement in charging speed or integrity/longevity of the battery by purchasing Samsung's 25W charger?

That's the charger I've been using w/ S21Ultra (25W from N10+) and I figured out I won't be needing anything bigger then that. Thanks to Samsung 'super fast charging' the 5Ah battery on s21U charges faster then 3.8mA Pixel 4a5G battery(with the same charger). +/- 1 hour and done!
Hey Folks!
Is it okay to charge pixel 7 (It supports only upto 20W charging ig) with a 65W charger? Will this have any ill effects on the pixel's battery life overall the device in any way?
It should be okay. Most likely your 65W charger uses quick charge technologies and will charge your phone at higher voltage instead of high current which is good for your phone (i.e. 1.3A at 11V instead of 3A at 5V). This result in much less heat generation which is the main battery killer.
In any case, your phone will only pull what it needs (and can) from the charge.
I use the 65W of my dead OnePlus phone without issues. The phone only pull a total of 25W anyway.

Hi, thanks for the reply. "Output: 5V~20.3V=3A (Max)" is what is written on my charger. Is it okay?
there is a voltage regulator, should be fine...
I've tried m1 macbook air charger with my P7 and phone recognizes it as "charging rapidly" and been charging impressively fast!

I think it's safe. I use my 65w mac charger for my P7 and its impressively fast. The phone runs hot while charging tho so I don't use it while it charges. Haven't had or noticed any issues so far.
It doesn'n matter how fast is the charger, the phone also controls the charging speed. If the charger uses the power delivery standard (wich is used by the Pixels) you can use even a 65W one (like Oneplus 8T's warp charger; 45W as PD), charging speed will be limited at 20/23W (7/7Pro). But if you use the 65W Realme charger (wich is also a warp charger but with USB-A output and without PD support), charging speed will be limited to 10-12W.
As long the charger is high quality, you should be fine. As mentioned before, the charger and phone negotiate charge voltage and current.
