Does this model really perform? As I've an existing YooBao 11200mAh External Battery but it doesn't perform as it is. It went dead on the third L.E.D. When I charge it, all 3 L.E.D lights up again.

Not to mention that I just charge my iPhone 2 times with 3G and Cellular Data off. iPhone 4/5 Battery is 1400-1500 mAh only. Plus minus running voltage also can be 2500 mAh per charge. So I'm puzzled.

Please advice mirrorstore2

Cause if "YB-651 [ 13000mAh ]" works, you've got a buyer.
