Ruggedizing iPhones for the outdoor/tactical crowd is the main mission for mophie’s juice pack PRO, a Terminator-style supercase that more than doubles battery power and protects against everything from bad weather to gunfire vibration. The high-impact polycarbonate shell, wrapped in silicone, with waterproof speaker cover and anti-glare screen, serves up protection to MIL-STD 810G, meaning it is literally United States Military battefield-ready: no worries about rain, sand, sleet, snow, dust, shock, vibration. The on-board 2500 mAh lithium-ion battery adds 150% more power. Pass-through home, volume and on/off controls and USB cable means you can even recharge and sync up with iTunes without removing the case. For iPhone 4/4S. $129.95.
