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

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

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 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.

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.

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.

Charging with Power Delivery

Do Power Delivery (PD)-only chargers work with the Mi 9T Pro, and if so, at what speeds and which PD version does it support?
Can't really find any tests on this online, I'm surprised it's not standard to be honest -- using one single PD charger for everything is fast becoming the norm.

Yes. Qualcomm QC4+ adheres to PD standards, it's the first time they've done so. Xiaomi haven't used any proprietary charging, they've relied on QC4+ baked on the SD855. You'll get up to 27W charging, depending on the charger and battery level. I find I'm only getting 27W when the battery is very low, normally it's 24W until it's nearing full, but that might be how my charger chooses to deliver the juice.
Not sure what PD version it's using, but I'm sure a Google/Wiki search on Qualcomm QC4+ will provide an answer somewhere.
Edit: a quick look on wiki says that it's PD 3.0

Oh awesome, what charger are you getting those speeds on if I may ask?
You might've just helped me to make my final decision to get the 9T Pro then. The only thing I'm still hesitant about is the lack of HDMI-out and color-notification. If this phone had color notification and HDMI-out... my lord.

I went for a bit of a gamble on AliExpress and got this one.
https://s.click.aliexpress.com/e/tGXqRBeY
It was a brand I hadn't heard of but had good reviews and was cheaper than the known brands. So far I'm happy with it, does exactly what it says on the tin.
For the price there's nothing much to complain about, you start adding on all the nice to have extras and suddenly the phone would be half as much again.

And you got 24-27w through the USB-C PD port? I guess that must be, since QC3 max is 18 watt right. Grand, thanks for the info!
Not so sure regarding the price, although it's a bit difficult to weight the pros and cons sometimes. Take the Black Shark 2, which is great, aside from the absence of NFC, and no bootloader unlocking, but it's around the same price. Putting a color led in there and HDMI out, that would've made the phone pretty much unbeatable, even if it cost 50 euro or so more. It's definitely making me hesitant to purchase, because what if a 9T Pro equivalent comes out with those two things extra for 50-60 euro more? I would be gutted

Yes, the QC3 port only delivers 18W max.

I'm resuming this thread because I'm really confused on how get 27w charge on my Mi 9T Pro.
I'm using a UGreen USB-C cable that supports 60W Power Delivery charge with an Aukey 27W power adapter (ADEQ-ES-PA-Y8-B) with PD 3.0. The maximum current I get (verified using Ampere app) is about 3.150mAh which is the same I get using three different Quick Charge 3.0 power adapters, the only difference is when I use the QC3.0 adapters the phone shows "Quick Charge" text on lock screen + double flash symbols on the battery icon and when I use the PD charger I have no text in lock screen but only the double flash symbols on the battery icon.
Does anyone know if the "Turbo charge" is achievable only using the original Xiaomi 27W Charger?

It's no good looking at only amps. You need to know what voltage is being delivered too.
Watts = volts x amps
I have 2 PD chargers and both charge the phone at the full 27W, when the battery is empty.
I have a 30W PD wall charger which delivers 27W as 12V at 2.25A, but my 30W PD car charger delivers 27W as 9V at 3A

You can get apps which show volts and amps when charging. Search for Ampere in the play store, written by an xda member, I believe.
I'm using Havoc ROM, which shows these on the lock screen when the phone is charging.
However I've seen people say that these may not be accurate and suggest only USB meters give true figures. I've never tried a USB meter, so couldn't say if the figures I see are accurate or not.

https://www.youtube.com/watch?v=3nl5vyesUVE
It appeared to make a very small improvement. I'd suspect it's mostly down to the efficiency of the newer adapter. In practice the difference between supervooc 50W and 65W seems pretty low (far less than 15W).

Can it be charged with a 5 volt charger?

The phone need to be capable to take 65 Watts. Charger rating only says it is capable of delivering the said charge but if the phone is not rated or designed to take the charge then there is no use. so a 65W charger can be used by a 5W max rated phone and the phone gets charged only at 5W though using a 65W charger

Exactly!!! we need to check if the 2.0-65W charger is charging at 65W or 50W.
This can be done using engineer mode (*#899#), and check if is using 10V5A (50W), or more 65W (13V5A). Taking into account that max power is only used when the battery is near 0%... as it is being charged, 70%, 80% intensity decreases down to 1.2A...
I,ve asked to have a new Youtube video...

21w charging

This phone supports 21w charging, but it is only shipped with an 18W charger. (This charger seem to be able to give out 5V, 9 V (2A) and 12V (1.5A).)
Anyone have information on what version of USB-PD the phone supports? And what voltage is used to obtain 21w?
Has anyone got 21W charging working? As not all higher wattage usb-pd charges may support the 21W mode that this phone needs.

Well I can tell you do not use anything above Sony's recommended charging °W because anything above that - even with PD -- the device will intensely heat up.

Sony report 21W charging. So I'm not asking to go above Whats recommended.
I am asking more about the actual charging methodology, as the usb-pd system can be a bit complicated. And even a 45W charger may not correctly 'handshake' at 21w unless it's got the right voltage to offer.

Anyone?
No one has tried using a higher wattage PD charger?

Me too, I thought it'd be doing 12V/1.8A or something but 7V/3A makes sense. Definitely should make sure the cable is quality enough to support 3A. As an aside, the phone charges at 5V/1.5A for all non USB-PD compliant chargers.
I measured with a super cheap USB C meter that I've been sticking into random chargers for curiosity sake. Highly recommended :laugh:

Ok, ordered an Usb pd 3.0 charger today, the Arcanite one. As it also has a PPS option.
Also ordered as usb c power meter.
Let's see if it does the same voltage combination with this charger.

I just looked more into the USB-PD spec and I believe you'd need a PD3.0 compatible charger to hit the 21W since the charger needs to support PPS to hit 7V/3A. Otherwise I'm assuming it would negotiate to 5V/3A or 9V/2A if the charger doesn't have a 7V step.

So got a charger with PPS support (a USB-PD 3.0) an up to 30w charging. An Anker USB c to c cable with 60W support.
And using a satechi voltage / current measuring device.
But something isn't correct. It could be the usb-c voltage measure.
Using the supplied 18W charger, it's displaying 5.27V, 2.78A. that's roughly 15W. ( Picture attached).
Using the new 30W charger, it's displaying 6.44V, 2.77A. that's roughly 18W. ( Picture attached).
Still need to do more testing, not sure why I'm getting these readings. A bit below what I was expecting.

What battery % is your phone at? You also have to remember that the closer the phone is to 100%, the charging speed will slow down.
I have an Anker 30W charger and can charge at speeds of at least 3500 mAh (based on Ampere reading).

The battery was around 35%. Yes you are right once it got over 50% the charging rate does show down a bit.
Also the Ampere app was displaying 3600 or 3500 as the current. But even if we calculate that, that's only about 18W. But that app isn't very good at measuring charging voltage or current.

The charger's specifications are attached below,

Actually, did anybody find a 21W charger compliant with our device??? (I mean really delivering 21W...)
Edit:
I've ordered the Samsung Ultra Fast Charge 25W (ref: EP-TA800XBEGWW)
It is PD 3.0 PPS and delivers 3.3-5.9V at 3A or 3.3-11.0V at 2.25A.
I hope that will work...

In fact, I have been testing all my PD chargers (about a dozen in total -- I might have a problem!), and none has been able to charge my Xperia 1 ii at more than 18W. That's certainly decent, but it would be nice to get the 21W that the hardware is capable of.

I've finished my tests.
Both Sony charger 18W and Samsung EP-TA800 25W charger take 37 mn to charge from 20% to 70%. So, the extra power of the EP-TA800 cannot be used by our device, it does not provide the correct electrical intensity...

Finally, I've ordered the ARCANITE Premium PD 3.0 QC4 PPS 30W charger as mentionned above.

I've received the ARCANITE Premium PD 3.0 QC4 PPS 30W charger and I've done the tests.
To charge from 20% to 70%, the Sony charge takes 37 mn and the ARCANITE charger takes 36 mn (tests done in aiplane mode).
The small difference occurs below 50%.

Thanks for the update. It seems like the ARCANITE might not be delivering the 21W as hoped.
I also ordered yet another charger, the Baseus BS-C915, which allegedly supports PPS. The PPS designation appears in some pictures, but the specifications describe only a range of voltages (3.3-11V @ 3A).
With the Baseus, I get just under 18W (6.6V @ 2.7A) when charging my Xperia 1 ii. It's kind of strange that Sony claims 21W charging but doesn't include a 21W charger and doesn't even provide the specs for one!
