Customer Ratings:

I have used this many times with my cell phone and my Kindle HD. The best part is that it takes AA batteries that I can buy anywhere. I can use either to use or to charge. A+

I inserted new batteries and tried to charge our Kindle Fire but, it did not work. I also tried charging a Samsung Galaxy S3 and Samsung Galaxy Media Player with no luck. I returned it and am looking for an alternative.
