Your iPhone or Android device can go for a few hours on a full charge. But you will have to eventually recharge your gadget. You are going to have a hard time charging your gadget without its cable. Wrist Charge happens to be a smartphone charger you can wear around your wrist and take with you everywhere. You don’t have to deal with tangled wires or any mess for that matter. Pretty interesting Kickstarter project if you ask us.
