Mophie Juice Pack Pro
Made for iPhone 4/4s
 
In 2012, ANDESIGN partnered up with Mophie to design the first rugged external iPhone case with built-in battery pack that gives your device double the power. The Mophie Juice Pack Pro was designed to keep your device charged while you’re out in the wilderness far from any power sources. This extremely portable and durable case ensures your device can withstand the rigors and abuse of whatever life may throw at you.
