One of the ongoing battles faced by smartphone and tablet vendors, particularly when attempting to bump the specs up a generation, is maintaining a relatively strong battery life.

There are plenty of remedial peripherals currently on the market, particularly for Apple's flagship iPhone 5, and in our quest to bring you as many of the latest and greatest gadgets and accessories, we'll today be checking out the NuCharge battery pack and case designed by London-based iKit.
