so we all know the phone will have a new super fast charging tech... the questions are
1. will it then requires special charger kit?
2. can it be charged using other devices charger?
3. what about USB charging, will it also get 'supercharged'? if so will it requires special USB port? if not then will it be like normal USB charging on other phones or what?
4. does the new charging tech have any weakness like prone to overcharging?
1. Yes, you will get a little different VOOC charger (still microUSB)
2. Yes, but you will get normal charging rate - the superfast charging will not work.
3. The answer is already in the answer 2.
4. That's hard to say, as the phone with this tech was launched 4 days ago.. Nobody got the opportunity to test it yet, however, Oppo claims it works without destabilizing the battery...

I live in Finland and just ordered the Nexus 7 (2013) from the US. I just realized we have different electric plugs and won't be able to use the default charger without an adapter. Couple of questions:
1) I have two miniusb smartphone chargers. The HTC charger says "Output: 5V = 1A" and the Nokia one "Output: DC 5.0W 1200mA". Will I be able to use these to charge the Nexus 7?
2) I think it's possible to simply use a piece to change the US plug type into the Finnish one since the adapter supports universal voltage and amperage ranges. Will this be the safest and most efficient way to charge?
3) It's possible to use a computer as USB power source. Will this work and how does this method compare efficiency/safety wise to 1) and 2)?
Update: support.google.com/nexus/7/answer/3257354?hl=en
The input voltage range between the wall outlet and this charging unit is AC 100V–240V, and the charging unit’s output voltage is DC 5.2V, 1.35A.

Your Nexus 7 can be charged via the USB port on a computer only when Nexus 7 is in sleep mode (screen off) or turned off. Charging through the USB port will take longer than charging with the USB charging unit.

4) Wireless charging looks sexy, but how does it compare to 1, 2 and 3? Any recommendations in that regard?
Update: Wireless charging has a speed penalty and the chargers seem to be quite expensive.
Your Nexus 7 will be fine with any USB charger. I have tested mine on 3 different chragers with US, UK, and EU voltage. My USB chargers all say 100-240v. I know EU and UK is 240v. So yes you will be fine with any usb charger.
As far as I know, all micro-USB chargers can take an input voltage of around 120-240 V, which it what you'll find pretty much everywhere in the world, and supply 5 V to the device, so no need to worry about that. The only difference between cables is how much current they can carry, but your battery will only suck as much as it needs to (unless it's limited by the cable, of course), so there is no way more current could go into it then it is safe.
I have also bought my N7 in the US and use it in Europe and charging it by using an adapter to convert from the US plug to the EU one works just fine.
Connecting it to the USB port on your computer will only give about half the current, which is why they say you should keep it off while charging. It will take about twice as long as using a wall charger and there is no gain in battery health. However, if you want to actively use the device, the current supplied by your PC may be less than how much the tablet is using, which will result in an overall (slower than usual) discharge.
I can't say anything about wireless charging, as I've never used it and I'm not planning on starting now.
tl;dr: Use any USB charger on any of your devices, no harm will be caused. The only difference that could show up is charging speed. :good:
Any way to disable rapid charging?
I have a generic USB extender and used it to extend my charger cable by a couple of feet. When the phone showed "full charge in 5 hours" I realized it's making the charge speed extremely slow. The USB cable is a regular sized USB male on one end while the other end is a regular sized USB female. You could use that to slow down your charging to about the speed you'd get by charging from a USB 2.0 connector on any PC/laptop.
One the same note will using a standard charger from other cell phones (that I have like 300 of) and the cable that came with phone cause any problems or just charge slow. I travel a lot and have several USB devices I bring and don't want to bring multiple chargers if I don't need to.
Thanks.
It will just charge slow.

You need a compatible charger for it to fast charge. Using a regular charger wouldn't put it in that mode. I wanted to know if there was an option to turn it off with a compatible charger.
Why do you want to turn it off.
I could swear I saw something in the framework to disable fast charging but I'm not 100% sure.
I'll try to remember to keep an eye out for it after the December updates drop from Google and I have to redo my framework mods.
As far as options in the GUI go, I don't recall ever seeing any option to disable fast charging.
To answer another question, someone may want to disable fast charging to ensure their battery lasts longer (short term + long term). Or to prevent overheating when charging in the sun. And other reasons too.
You could always buy a MicroUSB to USB-C adapter. Or the phone may have come with one too now that I think about it.
Then use an older MicroUSB charger to charge your phone.
Charging via computer is only like 500mAH compared vs. 2000+mAH charging from the stock charger.
Count me amongst the club who would prefer to slow-charge my phone overnight at least.
And possibly slow my car charger down to maybe just 1000mAH to prevent overheating while the phone is docked underneath my windshield under the hot sun.
In my last two international flights (United and Norwegian), I noticed that my OP3 doesn't charge when plugged into in flight entertainment system USB. When plugged in the cable, I also tried Ampere to see charging levels but it indicates the phone is not charging.
During flights, after noticing the issue, I tried the following when plugging the cable, with no luck:
turning the phone completely off/shutdown
tried using two different cables (one standard and the other DASH), both failed but otherwise work fine if used in any other USB port (e.g., workstation).
tried different USB ports (where others were charging their devices).
I also asked others to try charge their phones on the same port, two different phones charged fine (one was iPhone and other Samsung).
I am running official OOS 5.0.1 with blu_spark kernel. The phone used to charge fine in flight few months ago, so not sure if it's a software issue...
Any thoughts or solutions?
I'm sure the USB port doesn't supply enough amperage to charge the phone. It's probably just like my truck's radio USB port, it will not charge my 3T.

if that is indeed the case, then, on a technical note, how much amperage OP3 needs?
(I am asking because, as I mentioned, on the same port iPhone 7 and Galaxy S8 were charging...)

I have no idea. Maybe someone else would know that or you could ask OnePlus support.
Hi Guys,
I have a thinkpad which has regular USB and also a fast charge USB port. They have worked fine in the past on other phones and I used to see at least 1 amp charge rates. (on the fast charge port)
Using either port on the 20 X I only get about 200 ma charging rates?
I'm using "Ampere" to get the charging rates, it is definitely charging slower than normal...
Have you guys noticed this?
Also of note, It charges really slow from my car as well. On the hour drive home the phone only went up 4%. (This is a VW using android auto)
I think all bets are off when your using 3rd party chargers. I think Huawei might have some official accessories that you may need to buy.

I have a bunch of phones and every single one of them charges at normal charging rates off my laptop and in my car, this is pretty strange...
Huawei uses a completely different setup from QC 3 from charger to cable . How does it charge with the supplied charger and cable that you received with your phone? If you buy extra chargers for home or car make sure they say they do Huawei "Supercharge". They are a little hard to find but they are out there. Make sure the USB cable is rated for 5a(amps)

I haven't even used the included charger and cable, but plugged in at the house I do see 2 amp charge rates which is great.
The downside is that in the car with android auto I can't really plug it into anything other than the car's USB and that give me a really slow trickle charge. This is where a bulk of my charging occurs since I drive for work so much. Basically I have never charged my other phones outside of the car, I just use android auto all the time and the batteries are always topped off. So not being able to charge from car or laptop is not a deal breaker at all, but it certainly means I need to start carry a charging cube around everywhere.
Just seems odd for such an expensive flagship phone to not charge correctly via USB like every other phone I have ever had.
Try the supplied charger and cable just to make sure you do not have a defective phone. When you plug in the cable to charge watch your screen. It should show your battery percentage and a short lighting bolt. Then in just a second it should change to a long lighting bolt and say super charging. If it does that you know your phone is charging correctly. Take your Huawei supplied cable and use it on your laptop and car and see if that doesn't increase your chances speeds.

I gave the original cable a shot and it still basically charges at 200-250ma from my laptop. Very odd indeed. Not even seeing the normal 500ma that you would get on a regular USB port. (Tried both standard and high charge rate USB ports on my lenovo)
Anyone else seeing this behavior?
I'm having a weird issue that I can't wrap my head around so thought I'd ask in case anyone here knows:
I bought an ASUS ZenPower 10000 Quick Charge 3.0 (https://www.asus.com/Accessories/Power-Banks/ASUS-Power-Bank/ZenPower-10000-Quick-Charge-3-0/) battery bank and I'm not sure why but I can't seem to get it to charge the phone at over 12W.
I tried connecting it via a HAMA USB-A-to-USB-C 2.0 cable (rated at 3A) in the fast charge port - I get it show breathing color, indicating 12W or lower charging, with the phone saying "Fast charging". I tried to use the included USB-A-to-MicroUSB cable along with a MicroUSB-to-USB-C tip adapter with the same result.
After some digging I keep seeing that the S21 FE supports USB Power Delivery 3.0 but no mention on Qualcomm Quick Charge 3.0 so I'm starting to guess this might be an issue?
Any thoughts or tips would be greatly apprecaited.
Use a Samsung 25w brick/cable. Inexpensive, long lived and it makes battery troubleshooting much easier.

This is a battery bank, the Samsung-charger is not useful for troubleshooting.
I was able to get an answer to the question though so leaving it here in case anyone needs it - apparently the battery switches charging modes after connection - leaving the phone to charge a few seconds and then checking the light indicator using the button showed that it DOES use the "over 12W" (presumably 18W) charging mode.
So apparently using a cheap USB 2.0 cable, or a microB-to-C adapter tip does not influence fast charging, at least for this battery bank.

The cable must support the protocol, be fully functional or the power controller will default to snail charge.
Lol, Samsung learned their lessons the hard way with the N7.
Yes it is supported. My xiaomi powerbank uses QC3.0 18W to charge.
Your asus should support it too. Get a new cable and clean your ports.
You have the snapdragon version right? I do, and I'm not sure about that exynos variant as that is inferior and might not support it as QC is qualcomm's
