[Q] 4000mA Battery Charger for Gnote

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

What is the situation? is it totally blank/black screen, or the charging is not increase?

It charges.... but the problem is that my tab hangs..(or lags)

how many amp does the power output has?

it ususally happens when the power output is too large (not matching with the tab needed). happens long ago, when i'm still using s5360, and i borrow my friend's charger (even LG original charger) and my phone gets laggy.

If you can't find a Galaxy tab wall charger, I sometimes use an ipad/ipod wall charger to charge my Galaxy tab without any problem.
The ipod/ipad charger delivers 2.1A vs the Samsung charger 2A.

It is not about how many amp it is putting out.
The lagging and all is because the power is not clean.
Normally AC to DC conversion itself is already only an approximation.
If the components aren't good, a lot of noise is produced. And if the source is also not clean, it gets worse. It is typical for power supplies (in third world countries)
If you have an oscilloscope, you can see how is the output. I am pretty sure it is not smooth DC voltage you are getting.

Using different chargers question please

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.

I9305 Taking Forever to Charge

My sister got the GT-I9305 a little while back. Usually, she takes quite a few hours to charge it fully, about 7-8 hours. However, recently, it got worse. The phone has been sitting at 37% for over an hour now, and it is still stuck at 37%! I've searched for other threads on this issue but they didn't really solve my issue. It seems really weird that the battery hasn't even turned for the better(or the worse) after over an hour.
Anyone has any insight on this? Thanks a bunch!
P.S. Everything was off except for Power Saving mode and the mobile signal.

use a different charger, cable, port

i own that phone and i have to say that the charger is very weak 1000mAh charger for 2100mAh takes a lot i currently use my nokia's charger it has1200mAh and that makes a huge difference,my friend's uses nokia lumia's or of you have a recent computer you might have a supercharging port that provides much more power,

Hi everbody.
I use 2 different chargers, one from my tablet BQ Maxell Plus, other from another cellular...
NEVER had issues charging my I9300, with stock rom or other one....very fast and until 100%.
NEVER used the original one, but looking at it, is a joke of charger.....
Values: All debitate 5V, and 0.1 and 0.2 Amperes.
You must take in consideration other factors like electronic heat dissipation, filtrate, stabilitie, etc,etc with it seens not works well with the original one....
Who says that bigger ins`t better?:good:

1000mah is more than enough, must be a charger /cable problem

you guys are using capacity units on a charger. Chargers don't have any capacity, they have current, which is measured in amps, not amp/hours. So S3 charger would be a 1000mA or 1A, not 1000mAh

Never had a problem with the original charger. Charge time more than decent

right ^^ it's 1A and 1.2 A

Try disabling USB debugging if its on. Its in developer settings.

how can that have an effect on the charging current?

On some cyanogenmod 10.1nigthlies versions it has problem with charging takes forever with oem charger, i am now on sentinel rom 4.6 it has same problem. Just use usb port from computer or some media player. It charge to full in maybe 5 hours from usb port, i dont remember excatly.

I agree the S3 Lte does not have the same speed in charging as the 9300 I use to own even though the chargers are the same, even different roms don't solve the issue, need a custom kernel to up the charging current that was available with the i9300 to reduce charging times

charging note3

I usually have my note3 plugged into normal usb port on my notebook as i work to recharge it just using a normal micro usb cable.. i noticed that re-charges usually take forever and even after 2-3 hours of charging it only goes up only about 10%... is this normal ? my previous phone iphone 2-3 hours on a charger its fully charged.
is there anything i can do to speed up the re-charging like asus ai charger ? or anything else ?

Usb 2.0 is limited to ~ 500ma, the phone will pull 1.2a- 1.5a on the Samsung charger

The ASUS AI charger is for 3.0 only I believe, and your Note isn't compatible with that. I purchased one of the RCA plugs from Lowes that has 4 USB ports on it and has an output of 4.1 or 4.2 amps and using the 3.0 cable that came with the phone it charges it very fast.

Here's what I use guys. I used it on my Note 2, my brother's S3, my Note 3, and also my LG G Pad 8.3. It has about 1.8-1.9A charging capability and charges a little faster oddly enough than the 2.0A stock plug when plugged into the wall. Yes, it's a wall charger, so that's obviously the best way to charge. It's cheap and very convenient; the cable is actually quite long, which is much nicer so you have more room to move around when charging. You won't be disappointed. I don't advertise garbage products. I always look for the best quality things and share my results and opinions to help others. Before my Note 3, I had rooted my Note 2 and had Perseus kernel; I increased the charging values so I could utilize faster charging, and this charger was the best for that. I highly recommend it. I've had it for about almost 11 months. It has never given me any issues, and it has great reviews.

So what is the max that note3 will take?
