dont buy charger from ebay..)) go to local shop and get one universal for samsung.. the charger is the same as for SGS1 mate....
second thing is the same - for car charger...just buy a charger with micro USB even for HTC or NOKIA..they are all the same...
dont make things complicated...

W.r.t. car chargers: They are not all the same !
The difference is in the charge current they can support.
There are 500 mAmp versions;
There are 1000 mAmp (1 Amp) versions;
And then there are a few 2000 mAmp (2 Amp) versions.
I would at least get a 1 Amp version to be sure that charging is more than an active SII would alreday consume (GPS, Bluetooth,...)
I myself bought a 2 Amp version.
(Note the standard Samsung Wall-plug delivers 700 mAmp.

alright thanks!!!

Have you used the 2A charger with the SGS2? If so did you experience any problems like overheating, stopped working etc?
How about charging time is it any faster?
I'm thinking of using my old HTC charger 5v 2a and would like to hear your thoughts
Thank you.

I always used 1A 5v car charger for every phone I owned. but with gs2, it made me sick. overvolting everytime, both with 1A and 250A (btw better 250..) and it causes freezing.
more A isnt better, our galaxy has an internal chip wich brings A to 0.7A anyway, even with 10A input.
buy an original samsung car charger

thanks for the reply!

I just bought a 2A charger. I'll let you know my experiences.

Please do! Thank you.

I too would be interested to hear how your 2A charger goes. Especially for long journeys (e.g 2 hrs+) with GPS on the whole time!

I just bought a 1200mA wall charger
It's Nokia's Fast Micro-USB Charger (AC-10) for 10 euro inl. shipping from ebay
l let you know my experiences

I have a 2 A car charger. Originally sold for the Ipad2.
Works well - no freezing, but the phone still tends to discharge very slowly whilst using Sygic with GPS on and bluetooth. This is a common issue on the SGS2 and is NOT solved by a high current charger. It seems that there is a limit to how much current the phone can take (possibly software implemented) and there is nothing to be gained between a 1A and a 2A charger

Thank you Mahniex for taking the time to post your observations.

Thank you Mahniex for your testing,
I also have a 1A car charger, but same problem here. After 200 Kms of driving with GPS on and BT on, the battery is draining so fast from 100% to 0%, that I can't use it a lot.
Maybe, there is also a problem with the cable. I use a Sync/charge Cable. Maybe if I could find one with only charging capabilities, it could be better.
I don't exactly know...

car charger for KF?

I am looking for reliable car charger for KF. Any suggestions?

It needs to output 1.8v 1.8amps .. which is more than most car adapters will support.

So, no car charging? Even slow? I mean, you can charge with 1A, slow but can do a job?

I think you are wrong about the 1.8v, my charger says 5v @ 1.8 amps, which means you could use any usb charger rated at over 1.8 amps.

Meant to say 1.8amps not volts. Most car adapters are 1amp or less. Many car lighters (the socket) max out at 1amp. Utility plugs may go higher, but the charger plug you use itself needs to support it.

You are right about the 1amp though, anything over 1amp will cost quite a bit more than the few dollars a 1amp adapter costs . In that case it would be worth looking into seeing if the manufacturer of the Kindle Fire sells a car charger, but I would only use that for trips, there is no way I would leave my KF charging in an unattended automobile.

Your best bet would be to find a car charger with a USB port on it that can support an iPad 2. If it can charge an iPad, it can charge the Kindle. Tons of good options on Amazon.

Charge
Wouldnt any cigarette lighter plug with a USB connection work?

I bought the "GTMax Black 2-Port USB Car Charger Adapter 2A" from Amazon, it has two usb slots, one with 1A and the other 2.1A. Works great on my Bionic, have yet to try it w/ the kindle though.

I'm using a 2AMP charger as wel and it charges just fine. Most chargers designed for the IPAD will work well. Just make sure it has a regular USB port on it and not the apple connector

Any USB charger with a micro connector will charge it provided the KF is using less power at the time than the charger is able to provide. It doesn't have to be rated for 1.8 amps. I've used everything from a 0.5 amp Motorola RAZR charger to a 2.0 amp charger and they've all done the job. The only difference was the time required. I can't see why it being a car charger would make any difference either. My T-Mobile 1 amp car charger worked just fine with it.

Most USB chargers will work
Hi,
As others have said, most USB chargers will work. However, there is one exception that I ran into recently and its well documented on the forums here - if your battery gets too flat. e.g. you left it at home when you went away, it will need at least 5V @ 1.6A to actually recharge.

1A or 2.1 A?

So, I have powerbank and I have 2 ways of charging: 1A and 2.1A. which one to use when charging my note 2?
Handwritten from my Note 2

Depends on the cable you'd use. Samsung cable will go near 2amp, generic ones do about 1 amp

I have samsung cable.. So is it smart to charge via 2.1 A ? Can it do some damage on the phone ?

I have a Momax external battery and have charged the phone with the 2.1A port. It didn't heat up, it didn't have any problems. I was planning on measuring the exact amperage that comes out of the samsung charger and the momax battery (iPower Pro), but I didn't get around to it, because I suspect the difference is actually smaller. There are many people who used more powerful chargers to charge their phones faster, and the only thing that degraded was the battery lifespan, but the difference in those cases was upwards of 0.5A between the original and the new charger. I find the 0.1A to be a small difference and I have no problem using the 2.1A port on the iPower.
So to answer your question, no, it won't damage your phone. Theoretically it damages your phone's battery, but it degrades anyway due to charging cycles, so you won't notice any damage caused by the extra 0.1A unless you plan on still using the note 2 10 years from now.

Thanks for reply mate ! I was thinking the same, but i needed some sort of confirmation tho

Use the 2.1A one.
The phone should only draw 2A from it anyway, that just means the port is capable of supplying 2.1A.
Using the 1A port will just charge your phone slowly, the 2.1A port should charge it as quick as the official charger, depending on which cable you use.

It is a matter of supply and demand. All USB devices can safely be plugged into any USB charger. Given an unlimited amount of current available from the charger, each device will still only draw only as much current as it is designed to draw. If the charger is rated 2.1 Amps or 5 Amps or 10 Amps, a 1.5 Amp device will still only draw 1.5 Amps. The charge rate will be at maximum Think of it like your house wiring. The circuit may have a 20 Amp circuit breaker in the basement but we plug in 40 Watt bulbs and 100 Watt bulbs and TVs and electric shavers that all draw different amounts of current. The 100 Watt bulb uses less than an amp but is unharmed being plugged into a 20 Amp receptacle (charger). Now we come to the flip side. If the charger Is rated lower than the device it just charges slower than it would if the charger could supply at least as much as the device uses. To go back to our example, the 1.5 Amp device plugged into a 1 Amp charger will take longer to charge that it would with a charger rated 1.5 Amps or higher. My analogy has one hole. If the stuff plugged into the house receptacles exceeds 20 Amps the circuit breaker pops. This will not happen with USB chargers as they limit the current and will not try to supply more than they are rated for. Stick to chargers rated as high as the one that came with your device or higher and you will be fine

Charge 2 SGSIII's at once?

I would like to get a charging cable that has 2 Male Micro USB connectors and 1 standard Male USB connector.
These are supposed to charge 2 cell phones through one USB charger, but I've read that you might need a higher capacity charger than comes with your single cable charger.
Will the standard USB charger that comes with our phone work, or will I need a higher capacity charger?
Thanks

Our S3's can charge at approximately max 1.1amps and perhaps more on a custom rom. Our stock chargers will not likely provide enough to charge 2 S3's at that fast rate. But, instead it will likely charge both at half that rate. So. I would get a charger that can handle more than 2amps...preferably 3amps so that there is plenty of headroom especially if the charger specs are over-rated. The S3 will only use what it needs and of course, it will slow down the charge as it gets closer to being fully charged. Also, note that if the USB Y-cable or splitter is not wired correctly, then it may not charge at fast rate.

I have a usb 2amp cigarette lighter charger and it has 2 usb ports for charging and charges my S3 and an HD2 together at fast rate when I use proper usb cable(s).
On a 2sec Google search, I found this 3amp usb wall charger (2amp + 1amp) example...or this Scosche 4 port 4amp wall charger although it says each port is limited to 1amp max. You can always put in a USB Y cable making 2 ports merge into 1 yielding 2amp max output...if necessary.
Here is a 2 port x 2.1amp per port example..which would give you maximum headroom and might work well for more demanding tablet devices etc.

buying new sgn charger

Recently, my sgn n7000 charger(1yr old) got damaged.
I am looking to buy new charger of same model, but after searching a lot, i coudnt find a new genuine charger online, most of them are boxed and loosely packed.
i got some gud deal for a charger but its 700ma, it will take a lot of time to charge..
While searching, i got at these product
http://www.ebay.in/itm/Buy-Online-S...?pt=IN_Mobile_Accessories&hash=item3384a4ebb8
but on the samsung website, the note n7000 is not in the compatible list.
i wanna know, will it charge my note properly or not. Will i t damage my battery..!
or else pls give some link whr i can get genuine charger.

charger
The charger looks like an indian version of the one my daughter received with her galaxy s4. White is the colour of her phone and the colour of her charger, it also was 5v at 2A. To my knowledge the charging of the battery within the phone is controlled by the phone and as long as it is supplied with its minimum requirement of 5v. it will charge at whatever current it can within the control of the power management in the phone.
Hope this helps ? I did look at the samsung website in india and they had power units for sale. I dont know where you are ?

Samsung India has 700ma chargers listed..
And do u charge ur note with that one..? Us thr any problem.?

charger
No mine is a 5v 1A samsung charger. I also have an incar charger which is a standard usb charger for any make of phone and that supplies 5v at 1A. I also have a Yiboyaun unit from china which charges just the battery, I have 3 additional batteries I use and charge with this unit from china. I have had this setup for more than a year with no problems.

You can charge N700x with the Note 2 charger (which puts out max 2A). It charges slightly faster than the original Sammy 1A charger/cable. It's perfectly safe because the phone will not take in more current than it's configured.

If it charges faster than 1A its not limiting the input. The note 1 battery is made for 1A chargers. Using 2A will limit the life span of the battery.
