The amperage specification is the charger's *limit*, it doesn't force current into a device.
So any charger with a current (amperage) specification higher than stock is fine, as long as the voltage is the same.
A device with a lower specification will charge slowly, and in some cases (AT&T official charger combined with navigation in daylight), the battery will continue to discharge!
I have a 2100 mAh car charger that works fine. So it doesn't matter.

It will work just fine

The capacity of one of those backup batteries has little to nothing to do with its current output capability.
Unless you screwed up your units.
mA - measure of electrical current
mAH - measure of a battery's capacity in milliamp-hours

I bought my G2X used and it didn't come with an AC charger. I've been using another charger I have from a LG phone (STA-U12WD) that is 5.1V and 0.7A. Was looking for a replacement and I read on an Amazon review that the original charger is a STA-U13WV 4.8V and 1A.
Can someone check their charger for me? Thanks.
You'll want both a high amperage and high voltage. Look for a 5 volt (or 5.1) and 1 amp charger.
Think of it like a water hose. Voltage is the pressure, amperage is the width of the hose. So higher width and higher pressure gets the most water. Also note that lowering the width of the hose increases the pressure.

hey redmonke, do you own the original charger? Can you check the model #?
and if you recommend a charger with higher amperage or voltage what are the limits?

I have the original charger that came with my T-Mobile G2x:
Model #: STA-U13WV, Output 4.8v, 1.0a
In my car I use a 5 volt 2 amp charger (though I'm not sure if it's 5 volt split across 2 outputs or if it's for one output, I'll need to test when I get back from university) . Look for 5 volt 1 amp on Amazon with good reviews.
I currently use a cheap 5 volt 700mA charger and it's alright, though it's not the fastest.

thanks man!
I use an apple charger. I also have a charger that can charge a battery and has a USB output of 5.2v @ 800Mah. I'm a little concerned of the 5.2v, I don't want to use it and 6 months later my phone stops charging or worse.
Guys can someone tell me a good charger for my i9000. My original charger was bricked and now im using chines charger but it get lot of time to charge...
If someone help me i definitely HIT THANKS....
Buy an original charger.

You just need one with a higher output current. I forgot what current the OEM one has, but you want one that has an equal or higher current output. Don't worry about overcharging your phone. It has a chip that limits the maximum current it can receive.
Hello,
the caracteristic of original are: 5V - 0.7A
But some china's power supply marked 1A rely deliver less...
If you can buy an original!

Yeah, if you buy a no-name Chinese USB supply then you either get your phone plugged straight into the mains or the circuits and components of nightmares.

As far as safety, current doesn't matter. At 500mA you'll be charging pretty slowly though.
i use 2A charger from TomTom and working fine even with working GPS navigation and still can charge to 100%.
can i use 2A charger on my HTC one s?
It will not hurt the battery?

You're completely fine. I think the battery might get hot, so keep the phone in a somewhat cool environment.

as long as it is 5VOLTS it should be no problem, but that doesn't mean that your phone charges faster

I do use a 2A charger in my car because the 1A was overheating. I do always use the GPS in my car + mobile network and BT are always on.
The 2A charger can charge my phone (now) whilst I`m using the phone in the car.
The battery draws only the power it needs from the charger not the other way round so you can use a 10Amp charger if you want to without doing any harm to the battery.
It might actually charge slower as the phone could pick it up as a generic usb which will only draw half an amp so as not to over-draw a usb port. I believe to get full 1 amp charging the data pins in either the cable or charger have to be shorted (connected.)

hello
My stock charger is us for galaxy s4 (samsung regular charger)
and then I found this (link above) with 2.1A
is it matter charging via 2.1A and not 2A? what is the different? it will charge faster/slower?
thanks
In Stock kernel there is current limit 1.9A. So everything above it, will be the same as 1.9A.
In reality, you will find that even 2.1A charger doesn't supply even 1.9A. Chinese charges definitely don't supply current thay claim. And beware of them - you may fry your device by such cheap charger.
Also, it heavily depends on USB cable as well. It has to be very short and very thick.
I have a Mediabridge car adapter that has a 2.1 amp charger on it. When I charge my S4 with it it barely charges faster than the 1 amp charger does. I think it charges at either 1.3 or 1.7 amps, sorry can't remember exactly.

How do you measure the exact amperage that it charges at?

I don't have the equipment to measure it exactly. So what I did was charge my phone from 50% for 40 minutes on my stock Samsung wall charger and then recorder the percentage it increased. I then took that number and assumed it was charging at 2 amps and used it as a baseline. Then I did the same test with my car adapter and recorded the results. The I figured out the percentage difference and came up with me estimates. I just don't have the data in front of me anymore but I remembered it being somewhere between 1.3 or 1.7.

The stock charger is fast at charging this phone. On my s3 it took forever . I would stick with stock

Chargers, power supplies, etc, don't "decide" the amps that go to a device - the device "draws" a certain amount. Just because a lamp is plugged into a 20amp circuit in your home doesn't mean 20 amps are going to be shoved through the bulb.
So if, as sorg says, the phone is only going to "ask" for 1.9a, you could plug it into a 5 amp charger and it would make no difference.

You already got your answer above.
No, your phone will NEVER charge faster than 1900 until a developer comes along and figures out how to hack the system to allow this. And it would be a potentiallly STUPID idea to charge faster than Samsung has deemed safe.
Go here to find out how to test your charging rate:

I have note2 right now which have to go. But I'll keep my office charger which is 2A.
Can I safely use it to charge n5?
Sent from SGH-i317m
Using chargers with a high power (A) is no problem, the phone will not "take" more than it needs.
Sorry for the poor english ^^
The issue is if charging IC can handle 2A current or not. I dying wanna fry it lol
I would think it should not be an issue while 2A ICs are widely used in our days, but "better be safe then sorry".

While AFAIK there's no 1.5A ICs, than its 99% safe to say they using 2A nominal IC.

If using a different charger was a problem they would have made the connection something other than micro USB.

Not really. Charging current depends on IC installed, not the connector itself.

From what I understand, you could use a 10A charger and still be fine. The handset will not take any more than it needs. Basically, the charger doesn't push current, the phone pulls it.

Thats correct and nothing else. No way to destroy a phone with too much A because it just takes as much it needs. The 2A on an charger is just the maximum power output. It is physical impossible to PUSH the ampere in the device.
