this looks to be a spare battery for the iphone 5/5s........ 2400 mAh....it has not been tested..if its like other batteries then no signs of uplifting or bubbling.........free domestic returns since it has not been tested...........and selling it as used.....not tested...........not sure what this is or how it works...........seems like it is either a charger or the actual battery for the iphone 5/5s........no usb cable...or charger......if its a battery and this piece fits on the back of the phone then it can also be a backup to another battery.....in very good cosmetic condition with minimal signs of use...some light scratches..............free domestic returns on this since it has not been tested.........
