Be careful with Huawei Power adapter: - Huawei MediaPad M5 Guides, News, & Discussion

Basically, when the charger is unplugged, the adapter runs in 5V mode, which is safe and good. But when the tablet is connected, then it is upgraded to 9V mode. any USB devices connected with a splitter on the charger wire will receive 9V also! This near doubling of voltage could cause devices to be fried, so make sure your Huawei power adapter isn't powering any hubs!!

Good catch!
Thanks for sharing.
I thought charges and/or device ports had a regulator to control input voltage?

Most electronics with a USB port will only be rated for say 5v, or maybe 6v to allow for naughty USB power supplies. 9v is nearly double 5v, and on sensitive low-tech chargers, like resistive ones that charge 18650 or whatever, you could expose the battery to a much higher voltage than what it should have, which could cause an explosion or whatever. I used a fan since it should be able to handle the extra voltage quite happily.

What do you mean fan?
Used a fan to cool what?

There is not problem at all. Qualcomm charge technology and USB 3.1 do the same. The charger and the device negotiate what voltage they want to send the same power but less current (more efficient). You are not supposed to o what you did, it your fault and not from Huawei.

what I was getting at is that if you were to use a splitter, like I did, then be careful, as the voltage might raise. This is not a concern most of the time, but it's good to just be careful.
My OnePlus 5T and it's dash charging only works when these 3 conditions are satisfied:
Dash charger
Stock OnePlus lead
Nothing else plugged in
otherwise it will default down to normal. It's a shame that this didn't happen on the Huawei charger, but hopefully this means that it will be easier for implementation for powerbanks, I can't find any dash charge power banks. And also apparently Huawei phones usually play nice with other chargers. (USB-C power delivery I'm not sure on this device).

I am just annoyed that Huawei do not use QC or USB-PD standards and I must use their charge to charge fast. I do not mind the 9v as my QC devices charges fast on the Huawei charger but not the other way round, forcing me to either change all my chargers or carry an extra charger.
Not sure if you are talking about FCP for in or out of powerbank, I have a Tronsmart powerbank that supports both QC3 and FCP out. It also supports QC in, which means it MAY charge faster with the Huawei's stock charger. I had not tested it that way yet but I think it should as the Huawei charger charges my other QC devices at QC speed.

I know your trouble, I have a OP5t, and that charges at 7.5W from my Huawei charger, when it can charge at 20W using dash charger, my mediapad charges at 10W from the dash charger, out of 18w capability. I do look silly carrying round two chargers with the same plug on them!!
Yeah no dash charger power bank, at least there is a Huawei FCP one like you said, I might get that as my next one, but I've got a lovely EC technologies powerbank, and that only does 10W no matter what, shame really as it is 82whr (massive!).

Luckily (for me at least!), I do not normally carry my M5 around and therefore do not need quick charge on it. Even if taken on holiday, it can charge overnight in the hotel. However this put me off Huawei (and OnePlue, Oppo and any other brands that do not use QC standards) for my future purchase.

Wow, I didn't realize how bad this bites. MediaPad was my first QC3 device. Used it's charger in my bedroom. Then got a LG v35 QC3 phone last week to replace old Nexus 6P (USB C-PD). So excited to see the Huawei charger fast-charging both devices. So irritating to now realize that the LG QC3 charger won't fast charge the M5!
And Huawei is using a proprietary QC3 charging mechanism? ie. are there any compatible chargers on Amazon or only the charger from Huawei will fast charge the M5?

Sorry, Huawei does not use QC standards but their own FCP/SCP instead. QC chargers will not fast charge Huawei gear but Huawei charger MAY charge QC gear fast.

So if I plug my M5 into a standard QC3.0 charger (9v I think), does it at least charge somewhat faster than a standard, non-QC charger? I would assume so. And are they're any 3rd party fasxt chargers compatible w/Huawei's dumbarse proprietary QC3 charging?

No it doesn't, as confirmed by a V/A USB meter. It will only top out at 5V/2A.
I repeat again, Huawei does NOT use QC3 technology, but FCP/SCP technology. If you are looking for a charger that can do both QC and FCP from the same socket, read through the tread again as I had already posted a brand and model that had been tested and confirmed to do both.

Ah, sorry, me dumb and had in my head that M5 was QC3. Now I get it -- FCP, not same as QC3. OK, I see your link and several other chargers compatible w/QC3 and FCP. Thanks!

Hi,
I have a ThinkPad E580 which comes along with a charger Type-C, on the charger has been written : OUTPUT: 20V-3.25A / 15V-3A / 9V-2A / 5V-2A
Is it safe to try charge my MediaPad M5 by this charger?

I had used USB PD adaptors on the M5 before and it charges fine, but not quickly.

My Pad (M5 10.8 WiFi) charges via USB PD with 18 Watts using the 9 Volt Profile. What doesn't work is Quick Charge. Power delivery works fine

Is there anything special about the actual Huawei furnished cable? I need a longer one than what was furnished.

But get a good one that supports high wattage.
Some cables only transmit 5 watts

My Pixel XL experience with multiple chargers so far

I was a Note 7 refugee so I have the stock Samsung fast AC charger here. Model EP-TA20JWE rated at 9v @ 1.67A and 5v @ 2A. It's in my kitchen.
I have the original AC charger that came with the Pixel XL. Model TC G1000-US rated at 9v @ 2.0A and 5v @ 0.5A I have only used once to get this information.
I also have a mobile charger in my car. It is labeled as Qualcomm QC 3.0 certified which is why I bought it as the Note 7 was a QC 3.0 device. It is a Choetech Model C0051 rated at 9.1v~12v @ 1.5A Max, 5.6v~9v @ 2A Max, and 3.6v~5.5v @ 2.4A Max (the iFixit teardown has revealed a Qualcomm QC 3.0 IC in the Pixel)
Additionally I have a charger by the bed which is from my Nexus 6, Motorola "Turbo Charger" Model SSW-2680US rated at 5v @ 1.6A, 9v @ 1.6A, and 12v @ 1.2A.
All of the chargers are using their original CABLE (USBA to USBC except in the case of the Pixel which is USBC to USBC) included EXCEPT the Motorola Turbo Charger, which is using a 6 foot long braided USBA to Micro USB cable with the Micro USB to USBC adapter that came with the Note 7.
What I found so far was all three work well and all three are recognized by the phone as a rapid charger.
I also found that at 60% charge and plugging in each one long enough for the lock screen to give me the "rapid charging XX minutes until full" message, the Samsung EP-TA20JWE fast charger charges it faster than the Google TC G1000US or the Choetech C0051. The Google and Choetech appear to charge at the same rate based on time until full. The Motorola Turbo Charger charges at an extremely fast rate, like it took it from 58% to 77% in maybe 5-10 minutes and was saying 15 minutes to full at 77%.
My battery life is phenomenal for me at 5-6 hours SOT, I have no issues with any of these chargers, they all see charging time every day. Turbo charger overnight, Samsung Note 7 charger when in the kitchen where I am a lot, mobile charger when driving to work or classes... (except the actual Pixel charger which I haven't found a use for yet but will probably go to work with me.
*Based on my findings I am going to put the Samsung Note 7 charger in the kitchen and the slowest Pixel charger in the bedroom and take the fastest Turbo charger to work.

I know my test method isn't to some people's satisfaction but the time to full calculation is based on how much the phone is charged now (which I kept within +/- 2% for each check) and how much current the device wants to draw from what's available. What's interesting is the device draws power much quicker than the Pixel charger supplies it when it is plugged into more capable chargers.

I have been having varying experiences.
My Anker QC 3.0 type C wall charger seems to charge rapidly, although at the 5V/3A only, with a 6.6ft USB 2.0 i-orange cable. Using a 3.3ft USB 3.0 cable, it shows charging rapidly when I first plug it in, but a few minutes later only shows charging.. but seems to be charging rapidly? My Tronsmart type C w/ QC 3.0 car charger, using an Anker Powerline+ type C cable, shows charging rapidly, but said it had 1+ hour until full when at 70%... Ampere only showed 1.6A being sent to the phone too. I tried an iVoler charger with type C and QC 3.0 and got up to 2050mAh, but it was likely only 5V (which I would expect) but still didn't seem to be charging all that fast.
I think this whole USB-PD thing is going to really be dependent on proper chargers and cables. All of these chargers/cables worked perfect on my Nexus 6P - doesn't seem to be the case on the Pixel.
Thanks for the experience folks. I had purchased a qc 3.0 tronsmart on sale at amazon which I was going to return. I got usb c cables with pd from monoprice. I suppose even if it doesn't fast charge at 18w (9v X 2a), I'd be ok with 15 w charging if I don't have to go out and buy a new car charger.
I mean faster is nice but if it still charges at a good rate, the lower current might help the battery last longer too right?

I have bad news for you. I have a Tronsmart QC 3.0 type C charger too - one from a year ago though, don't know if the design has changed - and it is NOT rapid charging my device. It worked perfect on my Nexus 6P. It will start out by saying "charging rapidly" on the Pixel XL, but after several minutes, goes down to "charging" and the charge time is 2+ hours, Ampere shows really low current, etc. It COULD be the Anker Powerline+ type C cable I am using... but I highly doubt it. I think the fact that the type C port has QC 3.0 is not playing nice with the USB-PD chip, and causing it to drop support for 5V/3A all together. I will test this more tonight with the stock cable and see if it works any better.
Did some testing: http://forum.xda-developers.com/showpost.php?p=69309771&postcount=30
Man I totally forgot about my Motorola Turbo chargers I got from Groupon. I wish I could find my @zerolemon charger too.. Ill test them with my USB USB Doctor dongles.. When I find them... lol
psa; cables make a huge difference in my experience.
I also have a tronsmart qc2 1 + 3 fast port car charger Ill test and post results.
Perhaps not the right thread but I have just been sent these USB-C cables to review for free.

Amazon says they are rated to 2.4A but will they damage by Pixel XL? I'm not expecting them to charge 'rapidly' but would be handy to be able to use them with an older 2A charger.
Do you think they are safe?

Why do so many people try to get a charger with as high a wattage rating as possible but ignore the fact that USB-C is limited to 3A and all you need to do is find a charger capable of delivering 3A.
What does wattage have to do with things?
Not trying to be a jerk, I'm just assuming I must be missing something here.

Because more watts = more power. USB-C may be limited to 3A, but it is not limited to 5V. Higher volts at the same amperage = more wattage = more power. If you want the fastest charging possible, you need a 9V/2A+ USB-PD charger.

I didn't realize it was OK to go with higher than 5v now.
Do you know if it's okay to hard wire directly into a 12V system for charging? Like in the car? I'm guessing "no it's not okay" but I'm still learning about USB-C.

tap = hard wire/splice into. As in, no adapter. Just a USB-C at one end and then snip the connector off the other end and use the two power wires and two ground wires to splice directly into say, the back of a cigarette charger's 12V wiring.

There is no way that would work, nor would it be safe. There HAS to be an adapter to safely charge the phone by regulating voltage and current, as well as shutting off the charge once it hits 100%.

It's my understanding that some/all of the regulating is done on-board some phones.
I know I never had any issues with my 3A 12v to 5v converter hard wired to S4 and Note 3 phones for charging in either my car or Motorcycle.
At least, I didn't notice any issues.

Well you're a brave soul. I wouldn't ever think to try something like that. Especially not with USB-C & Power Delivery now. The phone is responsible for some of the charging regulation, but the charger itself is just as important.

Because with USB PD the Pixel can charge at 18W by using 2A by 9V. So just looking for a 3A charger doesn't give you the fastest possible charging for the Pixel. Using a standard 3A charger will charge it at 3A by 5V for 15W. You multiply the voltage and amperage to determine wattage.

No definitely not. Car Battery supplies too much wattage/amerpage and its missing the PD ic and other protections in most good charger (over volt, under volt, circuit protection, trickle, power cut off, ect). Thats why all this talk about chargers and cables that do not meet requirements burning equipment/phones up.
It will never know when to stop charging or if over charging and catch fire...
Thats why its not advisable to buy cheap no name unbranded batteries, cables and chargers.
Usb c isnt just a connector/ plug theres an ic (computer chip) in control as well on both sides.
The chip in your battery talks w the one in the phone that talks w the one in the charger..

Car Turbo Charger

Does anybody know of a car charger that does turbo charge the Moto Z? Apparently Motorola/Lenovo doesn't offer one and a third party QuickCharge 3.0 I tried failed...

I don't believe that the Z Force is set up for Qualcomm Quick Charge. And while it doesn't Turbo charge, I use the Verizon brand rapid USB-C car charger. I've also read that we have to be careful with what charging cables we use with our Z Force phones.

At least Motorola claims it supports QuickCharge if I'm not mistaken. Apparently, though, it also has additional requirements for turbo charging to kick in... I looked at the Verizon charger, too, but a) there's not much info on its website, b) calling Verizon didn't help - they don't have a clue, and c) there is some comment / review saying that it "burned out" some user's battery (which is of course unconfirmed to be related to this charger, may have been something else).
Anyways, given the utter lack of info and the suspicion of harming the battery, I stayed away from it... not to mention the ridiculous $40 price tag.
On an other note, though, Verizon has the original Motorola TurboCharger (wall charger) at a 50% discount.

No USB-C device can support Quick Charge - it violates the USB-C spec. Any quality USB-C charger that is higher amp will TurboCharge a phone. Moto screwed up by using TurboCharging name with both QuickCharge and USB-C - they are different.
The Moto Z is absurdly picky when it comes to quick charge specs.
I have a Blitzwolf QC2.0 with a type C and a Type A connector in my wifes car, and it will ONLY enter quick charge if I use the Type C to Type C cable I bought from Blitzwolf.
It will not turbo charge if I use a high end Type A to Type C cable, but my wifes LG G5 will do so happily.
I also bought a QC3 compatible charger, with the cable integrated like the original charger, and this works too, and is faster than the QC2 charger.
Both are definitely charging at more than 10 watts, the maximum for 5V 2A mode chargers.
And in fact, using a Non-QC 5V 3A charger, caused my cable to melt, and start to glow.
Incredibly my phone charging port survived.
Blitzwolf may very well be the only brand that works fully, as I just bought a Chuwi QC3 power bank, and it will refuse to quick charge my phone.
But works on some others.
And on another note, I used the Type C to Type C in a modern laptop a while back, and when I plugged it in, my phone displayed the message about receiving quick charge.
If I'm not mistaken, the Type C spec allows quick charging, but only if you use C to C, with the extra pins it's able to keep better track of the charging process I guess.

Yes, it seems all matter of cables...!
I have a Blitzwolf QC3.0 too BUT I'm able to obtain "Turbocharge" indication only using a *single* micro USB to type C adaptor. This with every cable and every charger. Even when connected to a USB port!
If I use every other cable or similar adaptors (I've tested many...), the "Turbocharge" never shows (except original charger obviously...).
With Blitzwolf QC3 and this cable/adaptor I got a full charge from less than 5% in about 70-75 min... during the charge cable was OK, while the adaptor (with metallic/aluminium exterior) was quite warm but never really hot in dangerous way...
Here's more information than any of you probably care about, but I'm tired of seeing the same misinformation and confusion being thrown around (not just in the Moto Z forum, but in a bunch of others, too).

That's not true. Case in point: my ZTE Axon 7 and LeEco S3 both use QC 3.0 and both are USB-C. The common confusion comes from using "USB-C" (a connector) and "Type-C" (interchangeably used to refer to the connector and the power specification) incorrectly. Clarification below.

This is mostly true. "TurboPower" is the stupid name Moto uses to refer to the Type-C power specification. Actually, I'm being unfair: it's confusing that they called it "Type-C" in the first place and Moto took the opportunity to market the spec as their own thing.
Before going any further, let's use a common analogy to make the relationship between, wattage, voltage, and amperage easier to understand in broad terms. Wattage is the amount of water going through a pipe. Voltage is how fast that water is moving and amperage is the size of the pipe. 15W is 15W, but you can get there by having a tiny pipe (1A) with water moving really fast through it (15V) or a really big pipe (3A) with water going more slowly through it (5V). They both move the same amount of power, but in different ways. Got it? Good.
Anyway, Type-C has a fixed voltage and maxes out at 15W ([email protected]). Quick Charge 1.0 does only 10W ([email protected]), 2.0 does 18W (5/9/12V @ 3.6/2/1.5A respectively), and 3.0 does 18W with varying voltage (3.6-20V) and amperage (5-0.9A) to match. That is the advantage of QC over Type-C: a higher voltage can (usually) be run through those old and cheap USB cables without issue since voltage tolerance is determined largely by the phone and the charger. As long as the amperage doesn't exceed the capacity (gauge) of the wire, higher voltage is fine.
Amperage, though, that's what causes non-compliant or crappy cables to burn up. Really old or especially cheap cables can handle 1A max (heck, if they were built to spec, only 500mA for USB 2.0), but most cables of reasonable quality can handle 2A without much issue. They tend to use lower gauge (thicker) wires and should *not* feel warm at all when using it to charge. Some manufacturers (Samsung, for example) used to disable data on their USB cables and use it for additional amperage capacity, which is why you would occasionally buy a phone with a cable that wouldn't work for data transfer in the computer but would charge your phone just fine.
Moving on. Technically, QC 1.0 and QC 3.0 do not violate the Type-C power spec. QC 1.0 because it can't exceed it and QC 3.0 because it's variable. That said, QC 3.0 (and possibly QC 1.0, I don't know) require protocol negotiation; if that negotiation is lacking (in the case of the Moto Z), it's going to default to a "safe" charging rate (around 5W, plus or minus some). Your QC 2.0 does technically violate the Type-C spec because its voltage and amperage rates are fixed: you can get 5V at up to 3.6A. The "up to" bit is the important part. I have seen in various threads folks claiming their non-QC 3.0 phones will work with QC 2.0 chargers just fine and it's probably because the amperage tolerance is there (ie. it will actually allow 3.6A, violating spec) or it gets throttled (ie. sticks to 3A, keeping to spec).

And in fact, using a Non-QC 5V 3A charger, caused my cable to melt, and start to glow.
Incredibly my phone charging port survived.

If I'm not mistaken, the Type C spec allows quick charging, but only if you use C to C, with the extra pins it's able to keep better track of the charging process I guess.

All Type-C and USB-PD compliant devices are picky about the charge specs, not just the Moto Z. Or, at least, they're supposed to be for the reasons outlined above (namely the amperage). QC devices are less picky because it frequently uses higher voltage, which we established above as being much more tolerable for cables of varying quality.
Your cable melting and glowing is to be expected when you push 3A through a cable that likely can't handle more than 2A or so. Your phone charging port survived because it's designed to handle 3A.
I'm not entirely sure about which pins do what on a USB-C connector, but you're right in the C-to-C is the only connection that (should, according to spec) support Type-C and USB-PD (Power Delivery). The rate is negotiated via the USB Power Delivery 2.0 "power rules", which define four acceptable voltages (5/9/15/20) and variable amperage (0.1-5) to obtain charge rates as low as 0.5W and as high as 100W. "Type-C" is part of the Power Delivery spec, but is usually limited to only the 5V rule. I'm fairly certain the Moto Z does not support anything past the first level power rule, which is why you likely won't find the Moto Z to charge significantly faster with the TurboPower 30 included with the Moto Z Force than it does with its original TurboPower 15 charger. No clue as to whether that's a hardware or software limitation.
Also, to answer the OP's original question: any reputable (Anker, Aukey, Choetech, Belkin, etc) that uses an actual USB-C port will work. Most (if not all) dual port units will have a USB-C port that will work with the Moto Z (or any other Type-C/USB-PD device) and a QC 3.0 compatible "traditional" USB-A port. I have yet to find one that includes two USB-C ports and I really hate the ones with integrated cables.
My personal favorite is the Choetech for $16 since its QC 3.0 USB-A port is reversible: https://www.amazon.com/dp/B01AAGH8OY/
This Aukey is cheaper ($15) and would be fine: https://www.amazon.com/dp/B01E764DXM/
Here's a Tronsmart for $16, as well: https://www.amazon.com/dp/B018K7LHBU/
Even this $10 Vinsic should be okay: https://www.amazon.com/dp/B014F2NQ36/
Just for funsies, here's a spreadsheet of the Benson Leung cable and charger tests: https://docs.google.com/spreadsheets/d/1wJwqv3rTNmORXz-XJsQaXK1dl8I91V4-eP_sfNVNzbA/edit#gid=0
Interestingly, the $10 Vinsic is on his list of approved. So there. Go buy a $10 car charger and be happy.
I have the aukey 6 port usb charging station with two QC 3.0 ports, I am using high quality braided usb 3.0 to type c cables - I have tested both QC 3.0 ports and the other ports (using ampere) - Every port lists charging as "normal" - QC port 1 shows a min of 640mA and a max of 1040mA. QC Port 2 shows - min of 530 mA and a max of 980 mA. Regular ports 3-6 all show a min of 270mA and max of 870 mA. Not one port indicated it was ever turbo or fast charging. This same charger does fast charge my lg G5 and Samsung S7 Edge.
this one is verified to give the "TurboPower connected" message when plugged in.
From what I have read, both QC 2.0 and 3.0 doesn't turbo charge moto phones. Qualcomms QC charging works by increasing the voltage and decreasing the amps. So you can have 12v and 2amp for a total of 24 watts, but that won't turbo charge the moto z. Moto works on 5 volts but needs at least 3 amps. It is the amps that seem to engage the Motos into turbo charge mode, and they have to be at least 3 amps.
This Belkin model, for example, is what Benson Leung uses for his pixel xl. Its one of the few on Amazon that is USB-IF certified for 5v 3amp.

Here's more information than any of you probably care about, but I'm tired of seeing the same misinformation and confusion being thrown around (not just in the Moto Z forum, but in a bunch of others, too).
That's not true. Case in point: my ZTE Axon 7 and LeEco S3 both use QC 3.0 and both are USB-C. The common confusion comes from using "USB-C" (a connector) and "Type-C" (interchangeably used to refer to the connector and the power specification) incorrectly. Clarification below.

I think you are propagating mis-information. If you want to catch up on why QC 2.0/3.0 violate the USB-C spec, here it is from the horses mouth:
https://plus.google.com/+BensonLeung/posts/cEvVQLXhyRX
https://arstechnica.com/gadgets/201...omm-quick-charge-with-android-incompatibility
Interestingly Qualcomm has QC 4.0 now and they call out integration with USB-C and USB-PD https://www.qualcomm.com/news/relea...livers-20-faster-charging-improved-efficiency
"Quick Charge 4 also integrates USB Type-C and USB-PD support, making the industry’s most popular battery charging solution available on the widest variety of cables and adapters."
USB-C has 24 pins while standard USB-A has 4. Quick Charge chargers (2.0/3.0) only have the 4 pins of USB-A - so if it can't use the data lines, then it can't quick charge via USB-C. Since there are only 4 outputs, plugging a USB-C cable into a QC 2.0/3.0 charger will not change anything. Still only 4 wires originating from the charger. The data lines are not allowed to be used for voltage, so your QC charger will only supply a fixed 5V to the phone. So no Quick Charge.
If QC3 supports [email protected] couldn't it supply power at [email protected] to turbocharge?
Looking for a solution to turbocharge my Moto Z and support QC3 for LG G5/Samsung S7.
The TurboPower 15 wall charger delivers hours of power in just minutes of charging. It includes micro USB and single USB charging cables so you can use it on compatible smartphones, tablets, digital cameras and more.
Have a Moto Z or another USB-C enabled device? The TurboPower 30 wall charger is USB-C compatible.

Tronsmart 33W Dual USB Car Charger with Quick Charge 3.0

Has anyone tried the below charger with the Mate 9? I thought it should fast charge since it's 5V 3A, but I'm only getting around 2A according to ampere. Trying to figure out if it just doesn't work or if I got a fake one.
USB Type C Car Charger,Tronsmart 33W Dual USB Car Charger with Quick Charge 3.0 Technology.Attached USB C Cord for Nexus 6P, Nexus 5X, LG G5, Pixel C (Benson Leung Approved) https://www.amazon.com/dp/B0146FK3G0/ref=cm_sw_r_cp_apa_9rWSyb3FQ80Y1
It's not going to fast change since it's 5v and not 9v like the OEM charging block.
Thanks. I mistakenly thought if it could fast charge a Pixel or 6p, it would fast charge the Mate 9. It does seem to be charging faster than a standard charger so that's good at least.
No, the Mate 9 uses Huawei proprietary super charging technology and he accessories today don't have it. We have to wait for more devices from Huawei to come out or companies are given the ability to use their tech.
Yeah, I knew it wouldn't be able to get super charging speed, but I thought it would be able to reach fast charging or whatever the middle speed is called.

The OEM Supercharge charger is also only 5v. It runs at a higher amperage, not a higher voltage.

Is our phone's quickcharge Qualcom quickcharge 3.0?

It only says Huawei quick charge in the charger. I was wondering if an external battery with qualcoms quickcharge 3.0 will charge just like the huawei's wall adapter
Correct me someone if I am wrong
But this is not qualcomm or snapdragon
This is an Huawei entirely made by Huaweis technologies like the HiSilicon and Kirin
Thats why it only says Huawei quick charge
And external battery will depend how you charge it
But I think it should only work with qualcomm and not Huawei

Correct, not Qualcomm QuickCharge technology, but proprietary Huawei quick charge.
Anker makes some good 'auto sensing' chargers that will charge the H8 pretty darn quick, however.

The Honor phones are not Qualcomm Quick Charge compatible. The Huawei Quick Charger that comes with the phone supports both Huawei Quick Charge and Qualcomm Quick Charge 2 according to its specs. So if you have an external battery that supports Qualcomm Quick Charge 3.0, you won't get the 3.0 speed from Huawei's charger, but it probably is quite fast (since I would assume your external battery also accepts Qualcomm Quick Charge 2).
Anker and Tronsmart QC3.0 and other proprietary fast charge speed up H8 charging, opposed to standard 2A chargers. Seem a bit slower than original charger but not by far.
Huawei uses their own fast charger.
OnePlus do the same.
When you already in this situation just try it out a d you will see how fast it will be.. and then let us know how it went.. maybe you will help someone.. I would also like to know if it will fast charge and if how fast
Any Qualcomm Quick Charger (1.0, 2.0, 3.0) will recognize that the Honor 8 is not compatible and will default back to the maximum amperage the phone's internal circuitry will allow. Not sure if it's 2A, 2.1A or what... but it basically doesn't matter what the charger is capable of if it's NOT a Huawei Fast Charger. It's speed will be dictated by the phone. Huawei's Fast Charger is the only charger that can get you the fastest charging speed on the Honor 8 and does so without heating up your device, which is the safest way to fast charge.
Huawei Fast Chargers can be found on eBay all day long for $10. There's very little reason to buy anything else since it too can charge Qualcomm QC phones and batteries.
I've tried charging mine with Aukey PB-T10 powerbank, which supports QC 3.0 (but not Huawei FCP). To my surprise, the phone shows "Fast Charging". Similar power draw between original charger and this one (9V, 1.2-1.4A), based on USB Doctor. And similar charging time too.
I've also tried with a QC 2.0 charger and it's just normal charging.

Wow, thats nice. Can I have the link? Is it this one?
Yes. This is my personal finding and nowhere an official statement :fingers-crossed:
A good QC3.0 would give very similar charging times as the original charger. I've not been using the original one and use one QC3.0 at home and another at work and they're pretty dam fast.

Extra Chargers?

Has anyone found any cheap chargers that can charge this phone like the Essential charger does (really fast)? I have bought two different chargers and neither of them can really even charge the phone. The lock screen says it's charging slowly, and the battery meter acts like it's charging, but it doesn't actually charge. The chargers were both Quick Charge 3.0 chargers too. None of my old phone chargers with a type-c adapter will charge the phone either.

No idea. Honestly, I don't know of anyone who consciously needs to control the speed of their charge. I avoid charging overnight by rapid charging during the day at work.
does it really need PD? they are kind of expensive and there are chargers out there with 5V, 6V, 9V, 12V @ 3A

I'm not sure how Android is programmed to display "Rapidly Charging", but I'm sure it's not by charging standard. Probably based on supplied power, but it definitely doesn't charge as fast as the stock charger. I noticed this with my QC chargers. It will say rapidly charging for a couple minutes and then just not charge at all or say charging slowly. Frustrating as hell so I bought an extra USB PD charger.
My Samsung chargers all work, and charge the phone to 100%. They just say charging, not quick charging, but whatever... The % goes up.

Phone needs a charger with USB-C Power Delivery and not QC. Anker has at least one model and Incipio has one as well. There are many others on Amazon.. The cool thing about those is that they also change my XPS-13. Only carry one charger when I travel.
I've got a few QC 2/3 chargers and a few USB-C PD chargers and what I've found is that depending on which USB-C to USB-A makes a difference whether I get rapid charge or not.
I'm slowly converting over to USB-C to USB-C but it is stupid expensive for some things like the power packs with USB-C...
Anyway, try a few different cables and see if it works for you, also it seems to work a tiny bit better on the Oreo Beta however my QC 2.0 car charger doesn't charge as fast as it did on 7.1.1 but luckily the car chargers are the cheapest USB-C PD items to buy, roughly about the same price as a cable.
One last note, the same charger and cable don't always go into rapid charging mode so replugging the cable in sometime kicks in rapid mode for me.
