Sheathing your iPhone 6/6s in the mophie Juice Pack Plus provides it with on-the-go charging as well as excellent protection against drops and scratches. The Juice Pack Plus adds more than 120% of your iPhone 6's total battery capacity and charges your phone at the flip of a switch. Mophie's Impact-Isolation System protects your phone against drops with internal bumpers that offer extra cushion to your phone's edges and corners. The case also features pass-through Priority+ Charging and Sync, which ensures the Juice Pack will allow your phone to be charged first, and the Pack itself second when plugged into a computer.
