I had read 2A Battery charger from other thread that you can charge Gnote battery in the span of 1 hour and 30 mins. I am curious if it is safe to use a 5V 4000mA battery charger for Gnote. I saw 4000mA charger and it is used for iPad and Galaxy tabs. Is there any one there who tried this?

Neither the 2A nor the 4A wont charger faster unless the kernel supports it.
None of the kernels that i have tested does faster charging
I have numerous chargers at home all of which have charged my evo, gs2, Nexus 7, etc.
Can these be used interchangeable in the Note 2 without harming the charging process?
Thanks
As long as the Voltage is the same (5V) there is no Problem. But you should have a charger at 2 Amper for optimal charging speed.
I just tried charging mine with the normal microUSB charger I use for every other phone I have had and it took 7.5 hours to charge from 5%-62%. I used the stock charger that was in the box and it charged it in 3.5-4 hours no problem. Seems like the charger in the box charges faster.
reading this thread made me curious, my NOTE II should arrive in about a week, I can't tell for myself yet, what is the A (amps) specification mentioned on the original charger?
as i come from HTC, my current chargers go up to 1 A current. witch is the double A a standard USB port will give unless crossover'd .
thanks in advance!

in the wiki thread i found the answer, the supplied charger delivers 5 V 2 A output to the device.

2A! Same as the Tab 10.1 charger.
Filling a 3100mAh battery requires some grunt.
i think even the usb cable makes a difference..
when i use the stock usb cable with the stock charger ..my s3 would charge up comparatively faster than with the other usb cable connected to the same stock charger.:rolleyes

It certainly does! :good:
All electrical cables have some resistance. Very low (but not zero) for quality cables, sometimes quite noticeable for thin and cheap offerings.
From Ohm's Law we know that voltage drop will be proportional to current. A cable with a resistance of just half an ohm will loose about 0.5% at 50mA. That's pretty much nothing. However, at 2000mA the loss reaches 20%.
dude use any charger, just don't use LG charger **** !!!!!
You must use the 5volt 2amp charger and cable provided or a replacement with the same output or youll either be waiting for ever for it to charge or do some damage.
I tryed using my note 1 charger rated at 1amp and guess what? It took about twice as long to charge.

Some of my old 1 Amp chargers aren't happy at all, and will often decide to stop charging randomly.
I though it was something weird with my phone, but after switching chargers it never happened again.

USA official charger
This are the images of the official USA charger that will comes when they release the device in USA
And yes its a 2.0A charger, so the SIII charger isn't appropriate for NoteII.
this is the kind of charger used in Canada, USA, and Latin America, i bought this NoteII in Mexico from an authorized Samsung provider, of course factory unlocked 710usd, like 10,900mxn.
Has anyone tried a 3A charger? Just wondering if this would speed up charging even more than the standard 2A charger.

No, it won't speed it up. It's what the device takes from a charger, and not what a charger can potentially supply. If the device's charging circuit is spec'd for up to 2A current, that's what it will suck out of a charger, not more. You can connect a 30A lab power supply, and it will still be the same 2A (or less) input. To speed up the charging process, you need to mod the charging circuit of the device itself.
hi i've won a 16gb nexus 7 but it arrived with a wall charger for the us, i'm using my samsung galaxy s3 wall charger to charge it, is this ok or will it damage it?
The N7 charger is 5v 2A as you probably know if you've looked at the US one, as long as your Samsung charger is 5v you will not damage the N7. If your charger is a lot less than 2A it will take a long time to charge and may overheat.
5v 2A chargers are cheap to buy on eBay or Amazon if you want one specifically for it.
I'm looking for advice on the quickest way to charge my phone.
With the stock (1.5MA) charger and cable I get about 1200mA current of charge
With a Mr Phone 2A charger it maxes at 1000mA charge current
With a friend's Galaxy Tab 2A charger it maxes at 1600mA charge current.
(Figures above were obtained using Battery Monitor Widget app)
So firstly I'm confused as to why the higher rated 2A Mr Phone charges less than the stock 1.5mA charger when the Galaxy Tab charger, with the same specs, is much quicker.
Secondly, what is the maximum current the M8 can charge at?
Thirdly, what have guys found to be the quickest way to charge? I was going to source a Tab charger as that seems to be very quick or order this Anker desktop charger: http://www.amazon.co.uk/Family-Sized-Desktop-Technology-External-Batteries/dp/B00EJA28ES
Check here at "Charge Time" and/or here.
The stock mains is Quick Charge 1.5, so the phone would charge faster than a 2A "non-Quick Charge" mains. If you need a faster charger, get a Quick Charge 2.0 compliant charger.
Edit: Don't think Quick Charge 2.0 mains are available yet. Have to wait for their release.

Quick Charge 1 is not part of a chargers spec. Only QC2 is.
There's no such thing as chargers that are quick charge 1 or 1.5
And that doesn't explain why a 2A Galaxy Tab charger is quicker than another 2A charger

Hey guys. Just got my mi max 2 with the xiaomi charger but only getting around 1450mAh a hour.. Nowhere near dash charge from one plus 3t (3600mAh).
I use ampere app to measure.. I also tried Aukey certified QC 3.0 charger but also not getting anywhere near 3000 mAh
What charger do you use to achieve quick charge?
I've bought a Anker power port anr cable. I'll test it out soon...
But the 2.5 hour charge with the original charger isn't that. I mean, with such a big battery could of been longer.

Aukey doesn't work for me and original charger with cable also doesn't work..
mi charge , 5V 3A
Used the original mi charger and cable. 17% to 100% in 1 hrs 45 minutes
