Hello guys,
Like most of us Android users I had some previous phones that were Android powered...
So with Motorola Milestone I had a 12v car charger, I used it too much with it, now I have a Galaxy S2, if I use the Motorola's charger to charge my phone there will be any problem?
Thanks in advance!

The important part here is the voltage the car charger outputs. I believe the standard Galaxy S2 outputs 5V (at 700mA [0.7A]). If the mA is lower, it will take a longer time to charge. If its higher, it will only draw from it what it needs.
So, check the output voltage of the charger is not higher than 5V and you should be ok.

I had a defy earlier and i have been using the motorola charger can i use the same charger for my s2..... if not how about these belikin\capdase chargers which have Output Voltage & Current: 5V 1A can those be used or should i use only a official Samsung charger....
bump!

It will affect the life of the battery or there is no difference between chargers?
Thank you!
Yes
But,
SGS2 charger rated @ 5V/0.7A
SGS3 charger rated @ 5V/1A
Meaning: Using the SGS2 charger with the SGS3 phone will charge at only 70% the rate > ie take longer..........
Edit: No, it will not affect the life of your battery, could even possibly extend it as the battery is affected by less heat generated.
Then I guess the same applies to using the charger of the SGS for the S III. That charger is also 0.7A.
(I'll be using it since it has a longer cord. The charger of the S III doesn't reach from the outlet to my night stand...
Just buy a longer USB cable that's all i did.
if anyone is ever stuck without their original charger i can confirm i have used my wifes old blackberry charger. my sons galaxy ace charger. and an iphone charger with micro usb cable plugged into it. all worked fine on both my s2 and now my s3. as long as it is micro usb and not crazy high amperage it should be fine.
So as long as amperage isn't too much over 1A, all is ok?

Apparently the SGS3 limits the charge rate to 1A max on AC charge.
SiyahKernel plus the extweaks app have an option to increase this limit.
Personally, I have never tried it, and don't particularly wish to.
So to answer your question, theoretically, the phone will limit the charge rate to 1A whether you're using a higher capacity charger or not. Most likely to protect the battery and charging circuit from damage.

I'm using the S1's one at the moment...same thing really, as the above poster said, might charge slower though.

This is wrong mate.
You CAN use the charger from the S2 even though it is rated 0.7A. It actually is capable of putting out more than that. You can use current widget to check this.
I have checked and on the S2 charger, the S3 draws 0.999A same as on S3 charger..
However, using it for prolonged periods will probably result in a damaged charger. I would use it only in emergency.

I never said you couldn't, just said it would take longer
My official SGS2 charger IS rated at 0.7 A (yours may be different), confirmed but not tested with a ammeter, which would be much much more accurate than any widget.
Can't borrow one from work unfortunately...

Apologies... Just read ur post again.
It won't take longer either as the S3 draws what it needs. The S2 charger will give out 1A although not sure how long it will last longterm.
I've used "current widget" and on quite a few phones now and it's pretty good. It might not be 100% accurate but it's not that far out. On my S2 the different charge modes in Siyah kernel could easily be seen in current widget. Same with my S3... Current widget reads same whether I use my new or old charger..

Is that safe? From what I get from http://en.wikipedia.org/wiki/Usb#Power , no more than 0,5A is expected to travel through a USB cable.
Is the cable we get from Samsung perhaps made for the 1A? It is quite a bit thicker than most other USB cables I have...

Yes , the device will only take what it needs.....no matter what the output amps are.
Devices are built to limits their input current.
Sometimes I use data cable from old Samsung to transfer data or charge.Still no problem.:good:
I've only ever used my S1 charger or my old S2 and now S3. Every so often I use a Nokia cable paired with my galaxy tab 10.1 charger and haven't had any problems.

Most devices won't draw more than they need. I've used anything from a 0.3A charger through to a 2A charger... in my experience the S3 doesn't charge any faster on the 2A, but it definitely charged slower on the 0.3A (perhaps because it was limited to a max output, I may have to see what this "current widget" says.
Here's the catch though, it will charge faster on a higher amperage during heavy use, than it would on a lower amperage.
how long s3 make to do full charge, i bought un old one, & after 2 hours il indicates 75% only??
I charged mine for about 2 to 3 hours.

So I will get the regular charger for gs3 that comes with the phone (tomorrow when i get the phone). but i also have the HP Touchpad charger which gives output of 2.0A. I was wondering if I charge my phone with the HP charger will it actually charge is faster then the regular gs3 charger? the reason i ask is cause in other threads ppl have mentioned that it only charges faster with non - stock roms like aokp or aosp roms. please lemme know if this will work. thanks
It should I got one of those and it does charge faster I got the bb one tho

I've used my BlackBerry PlayBook charger on mine and it doesn't charge any faster. That charger is 1.8amp.
It will not charge faster. The phone only draws as much amps as its allowed to. Whether you use a 1 amp charger or a 2 amp charger, it'll only charge at the phones own rate
Sent from my SPH-L710 using xda app-developers app
then theres basically no advantage to using some other charger?
I don't believe so. The phone only draws what it needs.
Sent from my SPH-L710 using xda app-developers app
A lot of chargers will be rated less than the stock charger. Especially cheap car chargers. In that case the phone can only draw at the charger rating.

Unless you run a custom kernel that allows for higher charge rates.

I have a dual car/wall charger and I noticed when plugged in the car it charges faster.
Sent from my vivow using Tapatalk 2
The values listed on the charger is the max output it can provide. If the setting on the phone or the hardware is set up to only pull 1A, then it will always pull that unless that is more than what the charger can provide.
That being said, you should be able to take the battery out and charge it faster separate from the phone. I've always read, though, that charging a battery faster ( i.e. turning up the current) will/may reduce the life of the battery

the only way I have found to charge phone's faster is to power it off and then charge...takes about half the time to fully charge
none of the 2 amp chargers make it any quicker

I have a Touchpad charger and it can be used, though I noticed that the phone got hotter than normal, IMO. The phone comes with a 1.0A combo wall charger with USB cable. Interestingly the Samsung stand and battery charger that comes with the spare battery comes with a .7A charger but the charging unit itself is 500mA/1A on the input with output at only 4.2v @ 450/900mA.
Hello, I have a HTC phone and I wonder if it is safe to charge my P7500 tab.
The phone charger characteristics are:
Input: 100-240V/200 mA
Output: 5V/1A
Thank you!
Hi,
The GT charger output is rated at 5V at 2amps. It's important for the voltage to be 5V! But the current (Amps) must never be less than 2amps!
So your HTC charger at 1 Amp is too low, and will cause problems with the charger (might burn out and get super hot = dangerous..
NOpe
I dont recommend my friend at all. low amp
Mickey
I think I can not !
My Gtab Sch-i905 will ONLY charge when plugged into the charge block it came with. will not charge any other way unless it is powered off. I HATE THAT.
Dangerous!!!!

I charge my Galaxy s3 using the wall charger and no problems and I also charge my tablet sometimes suing the phone charger too
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

Dramatically increasing charging current will also dramatically decrease battery service life
Just get a second battery and desktop cradle, instant recharging without any wear on the phone motherboard.

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.
