Which FAST charger I should order for my new Huawei P9

Hi to all
Just ordered a new EVA-AL00 from eBay last night. I am living in Canada. May I know which charger I should order to take advantage of the quick charging capability of the P9 ?
Is P9 using QC 2.0 or 3.0 ?
Please kindly advise ASAP.

HI
wrong! fast charging is supported by huawei fast charger
but only with this charger i tryed with asus 5v2A/ 9v2A but dont working

anyone who can provide a link to where i can buy one with an eu plug?

I'm considering buying this phone over the S7 (although still undecided) and I still don't get the battery thing (charging or battery life, I get people telling me all sorts of contradictory things that I'm having a hard time to fact check). That 9V/2A charger doesn't come with the phone, right? How much faster is that Huawei charger compared with the 5V that comes with the phone and what is it called since I can't find it on their site or anywhere? Is that the Mate 8 charger?

Yes it's mate 8 charger

Awesome! I need an Australian version of this, what do i search for; is it just a mate 8 charger?

Well, no EU plug still available. But it will be later I think. It is not QC 2 or 3, it won't work. Search for "Huawei 9V 2A Charger".
The result should be like this: http://www.ebay.com/itm/Original-9V...hash=item280f7d97a4:m:mNQwKZr7I5KHReS9CA2RwkA
As I metioned, no EU plug yet, so via adapter only.

Perfect, he had 3 and I nailed 2 of them
Hopefully these will quick charge.

Please post results!

The photo shows it is 5V 2A charger, so it is a standart, not a Huawei Quick Charge (9V 2A).

Just a quick question, what's the charging time with that charger? Does it go below the 2 hours for a full charge?

hi i never look before
i just charge now at 21h59 and 46% i will post the result at 100%
Edit: 100% at 23h02 ( 54% in 1h00 approximatly) but when i have the time i will try a full charge because the fast charge is more active at the start and midle of charging

With this Aukey charger I got from 5 to 95% in about 90 minutes

Aukey isn't compatible hisilicon fast charge
Aukey charge at 5V 2.5A no regulation so peraphs no good for the live of the battery

It's fine, it will charge as a standard charger at 5V. I would have to brush up my Ohm's law but I don't even get why Huawei's standard charger on the P9 has 2 Amp electric current value. What matters is the voltage going into the battery and you don't need a 2 Amp charger to give you 5 volts, a regular 1amp will be able to do that. The only difference I know is that 5V at 1 amp are 5 watts and 5V at 2 amps are 10 W. But that has only to do with resistance, I think, a battery isn't fed on watts?
I'm really on the fence about this fast charging thing now. I never got it. Qualcomm's has its QC 2.0 tech but a Motorola charger is faster than any other. An S7 Edge with amuch bigger battery charges as fast as an HTC 10 and the Edge has a 2.0 QC and the HTC is 3.0. The G5 is also 3.0 and charges way faster than the HTC, even compensating for the different battery capacity. And I own a G2 which has no fast charging at all and will charge from 0 to 100% in less than 2 hours on a 5V generic charger, which isn't very far off the times I see with 3000mah batteries and Quick Charge 2.0 or 3.0... Why these differences?? No idea... Somehow I think battery chemistry has a lot to do with it (it does in the RC and electronic cigarette world) but I never see anyone addressing that.
^^^^sorry for the rambling, just thinking/writing out loud

Nearly right! A little analogy may help... Think of Voltage (V) as the diameter of the water tap, Ampage (A) as the speed of the water through the tap and Wattage (W) as how quick you want the bath the taps are filling!
So you can see, a small diameter tap but high water speed will still not fill bath very quickly, neither will a big diameter tap and slow water speed...you need both together. So 9V2A should charge quicker than 5V2A (18W compared to 10W).
As I understand it the P9 will accept charging at 9V and 2A (their Fast Charging) giving max 18W input so a 9V2A charger should give the best results (which is what the P8's fast charger is)...and what the qualcomm quick charge 2.0 (and 3.0) spec can provide. Now i'm not saying the P9 is a qualcomm quick charge phone, it's not, but my QC2.0 and 3.0 car chargers certainly charge my phone quicker than the included mains charger! So i suspect that the car chargers are providing 9V2A to the phone.
Whether this means any 9V2A charger would do......I don't know

Quick charger query

Someone using quick charger 3.0 can tell me does it support quick charging or no ? I am thinking of buying one so does it support ?I am using NOS ROM with clarity kernel as of now

I hear santoni just support qc 2.0

Yes. It support QC3.0. I tested it with GreenCell QC3.0 MultiUSB Charger and Xiaomi Mi2i Powerbank - charging time is reduced by approximately 30/40 minutes

What is the voltage you receiving ? 9v,12v or 5v and amp as well ?

I checked it too. During charging, the charger regulates between 12 and 9 V voltage and 1.5A at 12V, 2A at 9V and 2.2A at 5V. When charging with the QuickCharge charger the biggest differences can be seen at the time of charging the first 40%, while in the later phases also large differences are visible, but not on such a large scale.

charger

in the box, redmi 6 provides 5V 1A charger, which is too small and slow for me. is it save if I use other original xiaomi charger from other device/series (such as redmi 4 series which have 5V 2A power)?

For me slow charging is perfect for battery life.

yes

Unfortunately, our devices have limited charging to 1A. The use of higher current chargers will not hurt, while the charging phase, unfortunately, will not accelerate :/

But remember that's a good point for battery life.

What? Is the Redmi 6's charging speed limited to 1A? I thought it could use 2A like any modern smartphone

Dash Charge Oneplus 3 Charger & Cable on mi 8

Hi ! I had 2 charger for my Oneplus 3 and cable usb type -c ( I had 3 cable usb type-c ugreen too but no charger)
Can I use my Dash charger with my mi 8 ? I had buy a mi 8 and receive it tomorrow global version with EU charger but don't know wich charger it Qc 3.0 or 4.0 ? And with my oneplus Dash charge is 5v 4amp can work on mi 8 or do buy another charger ? Thank you

it will charge at normal speed. I tried myself with original oneplus car dash charger, no fast charging for Mi8.

Ok thanks. I can use it no mistake but slow. I think buy a qc 3 or 4 it's good. For car I have too dash car and it's so good I loose it. I have car charger qc 2 or 3 I don't know.
Thanks

Why not?
It is a very good 5V charger, with Xiaomi you can expect up to 2A current, not more. Perfectly safe to charge anything, however not quickest charging option for others.

Bull*hit....
Dash charging just doesnt work on mi8, normal charge will not cause any damage on any other phone or their battery.
you do not necessarily need a original charger from your phone manufacturer.
The phone negotiate how much power the battery gets not the charger ... the charger slows down the load balance to 2,4A (2,4A*5V=12W)
With a 2,4A output you'll reach ~12W at peak due to cable limitations you'll get 10w
QC 3.0 reach ~ 18 watt on peak with variable voltage and ampere steps. (3,6 - 20v)
Same on Dash Charge, Dash uses variable voltage and ampere steps like QC but doubles the charging lanes.
You can charge your phone with any charger you get, the worst you can get is slower charging speed.

Bull****, the original MI 8 charge is QC 3.0 and I'm getting up to 3.3A on it.
It's very fast..

OKay its just your opinion but my opinion is you have no insight in electrical topics or the insight of such an charger.
optimization - the charger doesn't overcharge or use an overvoltage on your phone when its not support their specific fast charge technology it simply slow down to 5v - max. 2.4A, these charging speed will never cause any damage on your phone.
its just simple: an QC phone doesnt use the benefits of SuperCharge technology or Dash Charge and vize versa....
And trust me i've done more calibration and testing in USB charging topics and their different Charging tecnologys as you think (mobile batterys, chargers and so on).
I had several phones and several chargers and compared nearly all of them (QC, FastCharge, VOOC) and there is absolutely nothing dangerous to charge a phone with a QC charger if it is a supercharge phone.
But .... you ever can prove the contrary. I'll never stop learning but you have to tell me some facts.

Question Charging Pixel 7 with a 65W Charger

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.
