By Omar from CA US on Feb 11, 2011

I bought this battery because I was going on a trip. It exceeded my expectations. It fully recharged my iPhone once conveniently. It is incredibly easy to use and works amazingly for something so inexpensive.

4. Good Idea, Right Price

By Kenneth from US on Jan 12, 2011

I bought this because of the i-Phone in the family whose primary user tends to let it run down. Good insurance, especially if you think of your phone as a security device.

I am very happy with the life of this charger. It holds a charge for weeks that has recharged my iPhone multiple times. It is a little bulky,it charge very quickly.
