JUMPR isn’t like any other external battery you've seen on store shelves as it can charge your smartphones and at the same time revive your car’s dead battery in minutes – it even has a built-in LED flashlight to show that it means serious business. It also has a light source to aid you when your battery dies at night. The 12-Volt power at 300 amps meets the required needs of automobiles and motorcycles in order to come back to life when the battery gets juiced out. Met up with the local distributor of MiLi where they showed me their whole line of extended battery packs for all things made by Apple, including the new iPhone 4 and the iPad. It looks like a regular casing, though a bit thick, that doubles as a 1600mAh battery charger (adds up to about 80% additional battery life of a fully charged iPhone). They have ones for the 3G and 3GS as well as for the iPod 2G and up but I think external battery packs are more important for the iPhone since their batteries drain much faster. All battery packs come with a light indicator so you know how much battery life is left on the unit (you charge it back via a micro-USB cable that comes with it).
