It works for my Galaxy 4,... did the charging cable change? If not, then I would say yes.

I would think so. I have an S3 so I wouldn't know for sure but I don't see why it wouldn't also properly charge an S4.

Yes you can. So far I've had this device for 3 months now and it's still charging good. I use it for my iPhone 5 and iPads.

Yes you can, you just have adjust the "pins" and as long as it is not too big to fit it will charge it. it works for my S4 battery.....

There is a micro USB cable to accommodate all phones made after 2010 using the micro USB standard and there is an additional USB 2.0 port to attach a cable for proprietary chargers such as Apple's 30-pin or Lightning cables. 4000 mAh should charge your S3 almost 2 times over.

I used to have an iphone which I switched to Galaxy s3. I am using this cord as an adabter for iphone FM transmitter to with my Galaxy s3. I don't think it can charge your divice.

Yes it can, but when I bought mine it didnt have the s5 adapter because the s5 was not out at that time. If you did not know, the s5 can charge with the regular android charger. I hope this helped you with your question

I think you need something extra (the S3 does not support Qi charging by default). A quick search revealed this: http://www.amazon.com/Samsung-Standard-Wireless-Charging-Receiver/dp/B00BCC2B1Q, but you might find something else that works better for you.

Yes. Yes. This uses a micro USB cable to charge and you can use this cable for your phone or your own phone cable as well.

There is a micro USB plug in the my Charge Power Bank unit.If you have a cable that has a micro USB at one end and the plug to the Galaxy 3 on the other end, that will charge your Samsung.

Yeah it will work with an S3. Will it charge fast? Not as fast as a wall charger but it's decent. Also depends on what batteries you are using in the charger.

Don't know about your phone, but we tried to charge my Motorola Droid and my wife's Samsung Galaxy S3. Neither phone would charge from this charger. we have not tried charging anything else with it.

My daughter has an S3 and has used the charger and it worked fine.. It is a standard microUSB connector. According to www.phonearena.com both the S3 and S4 use the microUSB connector. http://www.phonearena.com/phones/Samsung-Galaxy-S4_id7597 and http://www.phonearena.com/phones/Samsung-Galaxy-S-III_id6330

Yes it will charge you S3 and will pick up NFC by tapping it. Im sure it could charge both if the adapter went from usb to a splitter

No, it will not work with a Galaxy S3 out of the box. You will need to purchase a Qi compatible receiver to attach to your phone.

Yes, it can be use to charge just about any portible device. I own one and gives it 5 stars. I love this charger.
