Samsung Galaxy S III Power Bank External Battery Case - 2200 mAhProduct Review (submitted on August 31, 2012):
I bought this battery and cover. I charged it in the morning and made full use of it. As of 10 pm, it is at 59% charge. I used to have another big battery with an extended cover to go with it and I dropped it and it shattered in pieces. I'm confident this one will hold up just fine. I would recommend this and buy again from this company!
