This case is like a portable power bank that's attached to your phone. The case is lightweight and protective, and it'll be able to charge your phone at least once if not one and a half times. There are handy lights on the back that indicate how charged the case itself is, too. When your phone is in need of a charge, simply flip a switch and your new case will get to work. Your purchase includes a two-year warranty for added peace of mind.
