The Icon Power Pack for iPhone and iPod from Ipevo is an external battery pack for your iPhone or iPod that looks just like the device’s battery icon. It uses EL film technology (electroluminescent film) to graphically indicate battery level with this lithium-ion battery. Futuristic indeed.
You plug it in to your computer’s USB port to charge up and then into your phone to give you a power boost. Yes it’s a bit of a style over usability thing here. To me it looks kinda bulky and awkward to use the phone with while it’s attached but the display is certainly very unique and eye-catching. So perhaps it’s a bit of a tradeoff but it is functional and stylish.
