This has been answered before
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.

About to get a Car Charger..is it OK?

Hello.
I'm looking for a Car charger, and i found this product.
It has a standard MiniUSB connector, and it has 1000mAH (out) and 5V (in).
Is this what i need? how can i know that it won't damage my device?
or any MiniUSB will do the job?
Thank you all.
help please?

It has to be 5v (out) not 5V (in). Car batteries are in 12v or 24v, that's your input. Any usb is in 5V, that's your output.

It won't damage your device, because the USB specification imply a voltage of 5v, so any USB-compatible device will charge with a 5v input, and any miniUSB will do the job.
Considering the 1000mAh (out), it's a bit underrated but won't be a problem. A higher power output would allow you to charge your battery slightly faster. Car chargers are usually rated at 1500mAh.

Charger replacement

hi,
i lost my original charger and would like to buy replacement. which can be not htc.
what are technical characteristics of the original charger?
mA, V?
i need with european plug.
thanks!
43 ones read the post and no one replyed. Cmon?! don't you have a charger near you? what are mA and V of the htc original 3part charger?
You can't expect people to reply within 7 minutes of posting a thread Give eBay a go, it'll be your best shot. I've got loads of extra chargers, but they have a US plug (not that hard to get a converter btw, super cheap).
Hope this helps http://cgi.ebay.com/EURO-AC-mini-US...ries?hash=item3ca4fc9c2b&_trksid=p3286.c0.m14
I've lost the orginal charger somewhere, and I was not able to find an original replacement. I successfully tried both following, but I use the second one:
1) Sony AC-U50A: Input Voltage 100 240 V 50/60 Hz, Rated Output Voltage: DC 5.0 V, Rated Output Current: 500 mA (http://www.sony.it/product/paa-ac-adaptors/ac-u50a)
2) Philips SCM2280/05: Voltage Required: AC 100-240 V, Voltage Provided: 5.6 V, Output Current: 500 mA (http://www.consumer.philips.com/c/power-solutions/universal-usb-charger-scm2280_05/prd/gb/)

Be careful with other chargers, they can actually hurt your device. If i'm correct, original HD chargers charge at 1000 mA, not 500. There've been several complaints with Motorla and Nokia chargers that end up messing the battery and the device so just a heads up.

Hi,
I know how to search the ebay or dealextreme.com. If you read my first post it asks for electrical characteristics:
what are technical characteristics of the original charger?
mA, V?
And not "where to find or how to use ebay search".
Thanks for your response.

Could you (or anybody else) confirm that original charger has a label 1000mA on the back?
Bulka..
Manau visi HTC pakrovejai yra 5V 1A. Turejau P3300 ten irgi buvo 5V/1A, dabar HD irgi tas pats...
I think all HTC chargers are rated 5V 1A. My previuos Artemis charger also was 5V/1A, same is for HD charger.

Ačiū. Ieškosiu reiškia 1A pakrovėjo. Maniškis atrodė taip pat kaip nuotraukoje.
Big thanks goes to golfietis!!!
500mA isnt the cause of the charge issue on other phones.
500mA is what PC USB sockets give, and will mearly take twice as long to charge your battery than a 1000mA (1A) charger.
voltage is the dangerous value here, but anything using USB-type connector should be 5v.

Charging the SGSII with 1Amp USB/Charger?

I notice that the standard AC/Charger is 0.7A output. Possible to use another AC/Charger rated at 1.0A output? What is the USB output anyways? Thanks in advance for any help or suggestions.
PS Still considering rooting or not (will it void my warranty?) *WUSS*
I am using my Galaxy Tab 2.5A charger to charge the S2. It still takes about the same amt of time to charge up full.
I believe the charger current rating is the max current it can supply. The S2 will still draw current at it's own max...maybe 0.7A.
Doesn't matter what charger you use on it, if it's greater than 0.7A The S2 will limit itself to 0.7A.
if you want raise charging amperage, you can help me looking for someone, who will change(raise) it in kernel...
http://forum.xda-developers.com/showthread.php?t=1132649
Given the same voltage (i.e 5V for USB), it's the resistance of the phone that determines how much current is drawn from the charger. Therefore anything above the rated 0.7A would work fine and dandy.
Thanks to all the fellas that responded! More than enough information provided.

The standard for usb is 500mA/5v and this is what you get out of most computers, usb hubs and so on. AC to usb chargers will also run at that more often than not. AC chargers on the other hand usually run hotter, up to 1A and more. I have a 1A and a 1.5 amp and both charge this phone at exactly the same rate. It was not so with my N1 where the 1.5 was quite a bit faster, certainly appears like there is throttling going on as others stated. I would be curious why they did this when some other ODMs are selling phones with 1A and higher rated chargers.
look in the source code, wall charging is capped at 650 mA and USB is capped at 450 mA. and this makes sense why samsung included a 0.7 Amp charger.

DC Car Adapter?

I have a DC Charger Adapter(I got for my Samsung Galaxy Phone) that allows me to plug in any USB Power Cable to charge a Device.It states it has a 2 amp Fuse and rated for 500ma. Does anyone know what the requirements are for charging a Prime from a DC source? I think this should work on my TP but thought I'd ask first.
Thanks
If it works, will be nothing more than a trickle charge.

To charge at a normal rate, you'll need 2.1 amps @ 15 volt OUTPUT. 12 volts output will also work, albeit slower.
Normal USB at a maximum is 2 amp, 5 volt output.

[Q] Max current allowed to charge the S3

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
