If you’re going to wrap your iPhone in a case, you might as well put it to work. Mophie’s Juice Packs add a little more bulk than the average case, but they also add hours of extra battery power through a built-in connector, so they’re perfect for the iPhone addict in your life. Or for Android users, a Galaxy S III Juice pack is also available. Prices start at $80.
