External USB battery packs for iPhones and other portable electronics have become so common that it’s pretty rare to see anything much different from the typical external pack that provides a battery of some capacity with a micro USB port for input and one or more USB ports for output. Sometimes we’ll see a built-in Lightning cable, or higher-end packs that also throw in an AC power port, but for the most part, battery packs have become pretty commoditized. Tablet2Cases has actually done something a little bit more original however, with Mangata Orbit, a solution that provides two lower-capacity battery packs and a charging dock, allowing you to always have one pack charged up while you use the other one on the go.
