The 'Juice Up' phone bumper lets you steal energy to charge your smartphone. Created by designer Francois Rybarczyk, the bumper splits in half to reveal two Apple Lightning ports. Upon connecting a phone to each end of the charger, you can begin transferring electricity from one iPhone to the other. An accompanying app allows you to choose how much energy to transfer between the devices.
Juice Up is able to transfer electricity while protecting your phone through an ingenious design. Copper cable runs along the edges of the case while a firm casing is hidden within the rubber exterior. As a result, the case molds perfectly to your phone so that the smartphone remains slim and portable.
