Mophie announced yesterday a brand-new case and battery attachment for the iPhone 4/4S that can supply the device with over 2x the battery life coupled with military-grade protection. The new Juice Pack PRO ($129.95) features water-tight ports, an impact-resistance rubberized case, and a rotating belt clip to make sure it doesn’t get lost while you’re outdoors hunting, fighting, camping, or whatever you end up doing.
