boostcase Hybrid Snap-Case and Detachable Extended Battery (1900mAh)
boostcase Hybrid is an extended battery for the iPhone 4 and 4S made up of a unique two-piece design: a minimal slim-fit and lightweight protective case that can stay on the iPhone at all times and an optional snap-on extended battery pack that when used can double battery life for iPhone 4 & 4S.
Double Battery Life
The Boostcase Hybrid includes a detachable battery pack that is lightweight at only 2 ounces despite its maximum capacity 1900mAh battery hidden inside an ultra-thin durable casing, all-in-all enough to double the battery life of the iPhone 4 or 4S. The extended battery has fully functional set of features including power on/off so you can decide when or when not to have power, battery level indication so you can check power remaining at any time, and pass through syncing so that you don’t need to remove the battery to sync with iTunes. The extra battery can be charged separately or with the iPhone together via the included micro USB cable and either the iPhone original wall plug or any other USB power source.
