Hi.
The charger we use to charge our s2 gives 0.7 A to charge the battery. But Note2 has a charger of 2 Ampere output.
Will it damage the phone if I use branded chargers capable of giving higher output ???
It won't charge your phone any faster, limited by hardware. But you should be able to use the charger safely.
No it will not work ... I have original samsung charger with 0.7A and with a multimeter i testet it and real output its 1A but while it is connected to phone it charges 0.650(5)A and it cluses touch problems but only while charging
2A will make screen unresponsibile and inacurate and could damage battery

You definitely shouldn't charge with any other charger then chargers made specifically for your phone, it can do nothing or it can make your phone trash, seriously don't take that risk.

As long as the charger is original and not cheap Chinese crap, you are perfectly fine. It is not the Amperage that matters, the phone will take as much as it needs, even if the charger gives less/more. For example :if you use a charger that gives 5v 300mA the phone will charge at 300mA.
If you use a charger that gives 5v 700mA (which I believe is the max the phone can take) the phone will charge at 700mA.
If you use a charger that gives 5v 9000mA the phone will charge at 700mA.
If you use a charger that gives 220v 300mA the phone will blow up.
This to say that Amperage affects just how fast the phone will charge, up to a max regulated by the phone itself. If you give more, you waste the exceeding. If the voltage is wrong, then you will surely have lots of troubles.

I know different chargers have different amps, but what i dont know is how much the phone (battery) can take at a time, even if the charger is 10 amp it doesnt been the phone get fully charge in 10 min.
Look for how much the charger gives out is not hard cause its label, but how much does the phone take?
cant seem to edit my thread (TYPO) nor find it on my profile, maybe its my browser.
Samsung phones charge at about 800mA. Samsung chargers have the two middle pins (data pins) soldered. Any regular charger, even with 2Amps will only max at about 330mA charging. The phone needs to detect that the two data pins are soldered. So higher Amps is not equal to faster charging unless you are using a Samsung charger or you have the data pins soldered( pretend to be Samsung charger)

No. The phone will regulated the charging on the device as lipoly batteries have a specific charging method. It is possible (for example) that the device may charge at 500mA maximum current draw, but a charger is rated at 1A. This would meen that the charger could output 1A without the voltage falling so in theory the usb output could be split between two devices. If the charger was rated at 300mA but the device needed 500mA then the output voltage may be very unstable and damage either the phone or the charger.
Choosing a higher rated charger will not charge the phone faster. Any attempt to do so with Lipoly chemistry could result in explosion.

You need to look at the output amp rating of these chargers. Chances are the output rating is too low to charge the player. These players came with .75mA chargers and the one you are using is probably kicking out too little of the "juice". Even if it registers, I bet it will take for EVER to even go 5% charged... You need a better charger.

SGP 5.0 AC charger is rated .7 A but it can be charged from computer USB ( 5V .5A)
I can get the battery icon to blink with thunder, but is not charging.
Tekkeon is rated 1A and is not charging.
Soshine is rated .4 A and is charging my old LG phone, 0.75A.But not the SGP.

Batteries in the charger maybe not powerful enough, just because your LG phones charger has the same output as the SGP charger does not mean they have the same minimum power requirement to charge. remember 2 AA batteries is only 3 Volts and so the charger has a transformer (not the optimus prime kind, lol) that ramps the volt up, the problem is when ramping up voltage your dropping amperage and without knowing the amperage of the double A's your using is impossible to do the math to see if that would give you the min output to charge your SGP.
It's also worth mentioning that those AA chargers are meant to be an EMERGENCY BACKUP and you should NOT use them to regularly charge your devices battery as this method of "charging" and I use that word lightly is very unhealthy for your players battery.

Hi,
I've read some threads here about charging the S3, but not all is clear to me. I would appreciate some explanation:
1) I've read that the stock chargers output 1A. However, on the charger I got with my S3 it's written "output: 5V 0.7A". So do you think I somehow got a wrong charger?
2) I want to buy a car charger for the S3. There are many generic car chargers in ebay, some of then output 2A current. What is the maximum current allowed for the S3? I couldn't find this number in my S3 manual or on the phone itself. Will a charger of 2A cause harm to my phone? or to the battery? or to both?
Thanks in advance!
bump... does anyone know?
My charger output states .05v=1.0a.
As for what aftermarket charger to buy, I would stay away from chargers with more output than the official for 'peace of mind that my charger's specifications are the same as the official charger that came with the phone' reasons.
Cheers
Generally wall chargers output 1000mA (1A) and USB ports 500mA (0.5A)
You do not want to purchase anything that goes above 1000mA

I attach a picture of the adapter I got with my S3.
It says 0.7A on it, while it appears that other have one with 1A.
Did they con me with this adapter?
And regarding the maximum current allowed: do you think an adapter of 1.2A might harm the S3?
Do not know where your S3 come from but this charger is not made For S3 but for S2!
I just checked the model number:
S3 charger: ETAOU81EBE
S2 charger: ETAOU10EBE (like yours)
And there is no cable on the S3 charger, it use the USB cable
Thank you for this!
I don't get it. The charger was inside the S3 box and looked original. Damn!
I think the store I bought from import their S3 from Germany, since it came with Vodafone German stock ROM. Is it possible that this is the charger they sell on German vodafon? Or perhaps the store switched it for some reason?
Mine also come from my carrier: french vodafone
Was your S3 box sealed?

Hi,
Background - I am an electronic engineer and have designed power supplies.
The Amp rating on a power supply is it's maximum capability to deliver power. The Voltage is the 'force' that it can push electrons through the device, this is the important one to have correct. So a 5V 300A Power supply will not charge your S3 any quicker than a 5V 1A power supply.
Get yourself a 1A car charger and you'll be fine. Depending on how the data pins on that charger are configured it'll be recognised as either a fast or slow charger but it will be fine in any case.
So, according to what you say, there should be not problem to use a 5V 2A charger on the S3?
The charger cannot accidentally push too much current to the device?
No. The phone limits the Amp the battery can get.
It simply won't go above 0.5 or 1Amp depending on what resistor is coded between the data pins (the 2 middle pins on the normal USB-plug)
(Note that this does not extend to all devices. E.g. cheap chinese toys and their batteries may not have any current limter, connecting them to "too powerful" chargers will result in damages or potential blow-up of the battery. The same applies to batteries without any electronic such as car batteries which can overheat and "cook")
I bought S3 in Germany 1.0A, there is a date on the charger:18.05.2012

Hi burmo,
An interesting concept. I have no clue in these things but what you say is not clear to me "all the way".
Charging my i93100 phone with 5.0V 3.1A will do no harm because it won't "push" more than 1A anyway?
And who is "responsible" for controlling this "push" the charger/battery/phone?
Does it work the same for Car chargers?
Thanks a lot,
Izik

so i have been wondering about this as well because i am currently building a custom charger for my s3 that charges the battery without having to plug into the charging port. i have redirected wires from the wireless charging port to metal tabs i have place on the back of my phone. it is a "drop in charger".
Anyway i have tested the charger that came with my phone. I also have the samsung stock charger that say the output is .7amp but after testing it with mutimeter, i have found that the output is actually 1.2 amps. As for max charging amps, I am not sure. I have tested several chargers. The new S4 charger puts out 2.34amps and i have not found any problem charging my s3 with it.

As far as I know the phone limits it so as you've found yes you will be fine
My original S3 charger is 5v 1.0amp
My original S3 charger is 5v 1.0amp. It was bought in Thailand with the phone.
I agree with burmo an advanced phone will have a current limiter as part of its circuit, however I prefer not to rely on it and not to exceed the manufacturer volt/amp recommendation.
The phone controls the current. In custom kernels (Boeffla and so on) you can change the target current. The phone has a protection built in, if the voltage is unstable (drops to much) it lowers the current untill the voltage is stable.
A HTC One charger I sometimes use (0,7A rated) only delivers 0,8A. A aftermarket charger I own (1,0A rated) is fine delivering 1,2A (modified target current, not stock). These charging currents can be read by various apps.
Get yourself a 1,0A rated charger and speed up your charging time.

Seconded the post above being an electronic engineer as wel.
Voltage should be exactly the same as you need, but this will always be the case for a USB charger.
Current should just be enough or more.
The charging current is dictated my your phone and not - and I repeat - NOT by your charger!
mine rates at 1A
Just curious if there is an app or something similar that would show how many amps are being provided when charging through a wall charger/USB powered hub? The reason I ask is that I'm thinking of buying a powered USB 3.0 Hub. The adapter that came with our phone says it's 2 Amp, so I am assuming our phone can pull 2 amps for charging. Just wanted to verify in some way that a 2 Amp dedicated port would really work for this phone.

When I get home, I'll download the kernel source and see if I can find out how much power it draws during charging. I doubt however, that it will draw 2A during charging as most chargers are rated to supply more power than the phone will accept.
Yeah, 2A seems like that could melt a battery charging that fast. Someone sent me a private message and told me to try CurrentWidget. I threw that on the phone and it registers as 1A while charging. But it appears like the widget doesn't break it down with decimals. For instance it could be charging with 1.8A and wouldn't know it. I put it in a standard USB port and it reported as charging with 0 Amps but the battery was indeed charging.
I took a quick look at the N7100 (International Note 2) source posted on Github by CM and it looks like AC charger is 650mA, USB is 450mA. It's a little hard to tell what exactly it's using for charging, so I'll try to verify that when I get home and have a chance to take a better look.

A 3100mAh Lithium Ion battery can easily handle a full 2A charge rate. The ideal charge profile for Lithium Ion is a CC/CV profile, starts at constant current between like 3V and 4V, which most LI batters can take a rate of 1C, meaning it can handle a charge rate of 3.1A, recommended charge rate to achieve the most possible charge/discharge cycles is usually 0.2C so for a 3100mAh battery that would be 620mA. Once the charge gets to the correct voltage it gets to constant voltage and charges until termination current usually in the 100mA range. So yes, it can handle a 2A charge no problem.
Hey there. I very much appreciate that breakdown. Makes me wonder why they dropped the amps so much during charge.

If this is true (first time I've seen this anywhere), that would line up great with the 650mA max charge rate I found. Also, I downloaded the VZW source, and it doesn't look to significantly different from the N7100 source, at least as far as the charger stuff is concerned, so I would say they both probably have a max charge rate of 650mA.
I appreciate the info and time you both put into this. I guess it means a 2A usb port will be slight overkill. Even changing the charge rate to a higher value seems to indicate a lower battery life. Makes you wonder how apple did it's math for the ipads charge rate. The battery must be huge to accommodate a 1.1A charge rate. Or they are sacrificing battery life for fast charging.
Wont the kernel dictate the charge rate no matter what the charger is rated at?
If the kernel is set for a charge rate of 650mA (0.650A), then why does the Note 2 have a more powerful 2A wall charger, while the GS3 has a 1A wall charger.

The original nook color 7" came with a 2A wall charger and that was 2 years ago... both my note 2 and nook color charge about the same rate (quick to 99% and slow to 100). The charger is probably cheaper to make at 2A rather than anything and plus it could be used to charge future devices. Also if you used a 1A charger to charge the note it might possibly get warm/hot from running at near full capacity.
Im using my OLD blackberry 700mA wall charger to charge the phone at night while im sleeping. No problems with heat.
I have an old 0.7A charger and was told that a 1A charger would be faster..
But how far higher can I go? Is there a 2A charger?

1A is stock for S3.
Maximum recommended is 1.5A,more may brick your whole device,if not the battery.

I guess using modified"boeffla or googymax " kernels will let your phone charge much faster
Maximum rating of the charger is irrelevant, the phone will only draw a safe amount. If you override that limit then you may blow the internal charging IC or rupture the battery.
Don't post questions in the general section.
The S3 can't charger faster than 1A, it will only draw what it can, I've used a HP Touchpad 2A charger since the day I got the phone, it still won't draw more than 1A. You can use custom kernals to draw more, but you'll find lots of stories of people who did it and fried the charging board.
I tested using 1.1Ah, and for the storioes I've read, it's the maximum value you can use with security.
Hi, you can have more than 1A, but you need to change the limit with boeffla (i made it for the USB charge)

Using 1.2A from months in boeffla kernel without any trouble, using stock charger.
I tried 2A once and it was fast (0-100 in 1hr) but its not recommended 1.5 max
Also I increased charging speed to 1600mah that time and it was working

Hi, i am getting a new charger for my tablet pc which uses a 5.35V 2A output charger and was wondering whether i can use this to charge my galaxy S3. so that i do not have to carry 2 chargers?
IS it advisable?
My S3 came with a 1A charger, my wife's S3 came with a 2A charger. I used her charger a few times and it worked fine. As of last week my charger is working fine, if I use hers with my phone I only shows "USB" in the battery info and takes forever to charge. I don't know if her charger did damage to my phone/battery but that felt strange, so I stopped using her charger.
