Mophie already has a bunch of exciting battery extenders available for iOS devices. Their latest battery case, Juice Pack Plus, is designed for your iPhone 5 and features a 2100 mAh battery inside. It will provide you with 120% more battery life so you can survive those long trips. The Juice Pack Plus is impact resistant and offers basic protection against bumps for your iPhone.
The case weighs only 2.68 oz. It lets you charge your phone and the battery at the same time. If you have seen and tried this case for the iPhone 4S, you already know what to expect here. This battery extender case sets you back $119.95 though.
Speaking of cool cases for iPhone, the OZAKI O! coat Lover cases are quite special. They are designed for couples. You get two of them, male and female versions. These cases fit together to show the love you and partner hold for each other. The design does seem to be a bit pointy which could be an issue for some users. You have 3 color to choose from.
