Have you ever taken your phone with you during a long trip without its charging cable? Your phone might last you a few hours on a full battery charge. But you will need to find a way to connect your device to a laptop or power outlet eventually. Wrist Charge happens to a smartphone charger you can wear around your wrist and carry with you without having to deal with tangled wires.
Wrist Charge connects your phone to USB ports. It is available for iPhone 5, iPhone 4, and Android devices. Wrist Charge could work for other mini USB devices too. This interesting project is being funded on Kickstarter.
