Verified Purchase(What is this?)
This review is from: Kinps®4200mAh Iphone 5 5S External Power Pack Case and Rechargeable Back Up Battery Charger For iPhone 5 5S- Black (Wireless Phone Accessory)
Bought this case purely because of the appaling quality of the iphones battery. I get more than 2 full charges out of the case. Only downside is it is large and heavy but that is to be expected.
