Can we use this USB to fast charge our Note ?
Anker® 40W 5-Port Family-Sized Desktop USB Charger with PowerIQ™ Technology
Thanks
It's a charger that will charge fast simply because of the high amperage. I believe, and trust me I could be wrong, the fast charging capability has to do with the plug's output. Your typical outlet plug is 5v, anywhere from 500mah - 2.x amp. The higher the amps, the faster the charge. If you look at the fast charging plug, you'll notice it's 5v 2.1amp OR 9 volt 1.67 amp. I believe the ability to fast charger comes from the higher voltage capability. So while the 2.4amp charge rate is good and will charge fast, it's not the fast charging like using the higher voltage Samsung plug.

I have a 800ma charger that seems to take forever to charge my phone. I also have a 1A charger that charges significantly quicker. I am trying to determine if the cheap 800ma charger I have is just a crappy charger or do 1A charger charge that much quicker?
OE charger is 1A, from what i've seen it charges the phone the fastest, i should check what my charger at work is b.c i find it charges way slower then the OE
1A is the most it will take or you can just plug it into your computer @ 500ma. So 800ma will work just fine
great to know thanks so much!
The phone detects if you are using a wall or usb charger, the second is considerably slower. Some usb chargers cheat to seem wall chargers so charges much faster.
Seems Qualcomm which charge 2.0 not working with Mi 4 original cable anyone suggest how enable fast charging on Xiaomi mi 4.
If I'm not mistaken, you need a charger with higher outputs then the standard wall charger shipped with most phones. Just a guess though seeing as my Xiaomi Mi 4 charger is a five volt charger.

My charger say Output 5v=2A/9v=1.2A/12v=1A i dont know if that whats needed but it charges very quickly.

5v is the voltage standard. What you want is AMPS. ALWAYS select 5 volts.
Computers (USB 2.0) can output maximum 0.5A (500ma) at 5 volts, while USB 3.0 can output 900ma or 0.9A.
Most MicroUSB chargers output anything from 1A to 3A+, with 1A and 2.1A being the most common.
So while a 1A will charge your phone a X percent per minute, a two amp charger will charge it at almost double the rate (not exactly, but close enough).
I do however (and I stand corrected), recommend not to go too high an amperage, while your phone my not get damaged, slow and steady charging is better for the battery than high current, quick charging.
Some phone, like my Galaxy S5, requires a 2A charger, but other phones may not like it.
I think it's always enable ...
What is your S8 charging rate? (from 0% to 70%)
Mine is:
Fast charge adapter, fast charge on: 2.4A
Fast charge adapter, fast charge off: 1.6A
1A sony adapter: about 900mAh
Computer: About 500mAh
I tought "normal charge" with the fast adapter would use a lower rate. What do you think? I choose longevity (low current and low temp during charge, not going over 4.1v) over charge time, so i charge the phone to a max of 80% and at the lowest rate possible. I usually plug it in when i get home from work, and about bedtime is charged.
(My 3 year old Z1c still got 1 day battery until i broke the screen)
Fast charge adapter, fast charge on: 2.4A
Fast charge adapter, fast charge off: 1.6A

I think you mixed up your measurements.
Fast charge is 9V @ 1.67A (15W)
Standard charge is 5V @ 2A (10W)
Will any chargers that supply higher volt / amp combinations charge faster than standard or does it need to support dash or warp charge? I don't necessarily need the warp charge but faster than my current op2 would be great.
Anyone? Does higher amperage equal faster charging or does it have to be warp charge compatible?
There's communication somewhere along the path that allows dash/warp charge to happen. A charger can supply a high enough amperage, but your phone may not be able to utilize it without communication from the charger/cable. I'm not exactly sure how/what the process is, but I know it's not as simple as using a high amperage charger.

Any USB-C power delivery charger will do a rapid charge, just not Warp.
Hi All,
I am not an expert and hence seeking suggestions.
I have Xiaomi 120W Power Adapter (with wireless which can also be used as wired) and wondering if I can use for the S22 Ultra (Snapdragon version).
Thanks
If the power supports USB PD PPS it will charge at up to 45 W. If it only supports USB PD it will charge up to 15 W. And if it doesn't support USB PD at all, it will charge between 5 and 10 W.
It should be noted on the power adapter itself whether it supports PPS
My Huawei 65W USB-C PD charger used with the Honor Magicbook 14 charges at a report "Superfast" rate but that means anything above 20W. Of course there isn't a measured difference between a 25W and a 45W charger according to GSM Arena so YMMV.
Thanks all. As per this article it does
Xiaomi 120W Power Adapter Supports QC5 and USB PD + PPS Over USB-A Port

Hopefully no damage to the phone.
Does "Super Fast Charging 2.0" mean it's charging at 45W?
What is it if it's just "Super Fast Charging"?
Only one of my many third party chargers seems to show 2.0

Superfast 2.0 means anything above 25W I believe.
Super Fast Charging I think is between 15 and 25W.
Both of these would be potential speeds, as the phones won't charge at max rate from 0-100%. The rate starts slow at 0%, rises slowly to max, then starts dropping between 60 and 80%, falling to 0 charge rate as the battery reaches 100%

Thanks. All these different standards get very confusing!
I would have expected my "Anker Powerport III 65W PPS charger" to show 2.0, but it doesn't. The "MINIX 66W Turbo 3-Port GaN Wall Charger" does.

I just learned this myself, - but check your cables. The S22U is rated for 20V input, so it checks with the cable to make sure the cable can supply the correct power. USB-C cables have chips in them to identify the cable and its capability. If you use the cable that came with the phone you might get different results. I did for sure.
The PowerPort II also doesn't output the right voltage for the S22 from what I can understand. So there is that.
