new technology, Double E power bank. Is an external battery pack that allows you to charge your devices by shaking it, its by Yanko design and created by Theming Zhou.
Not the most ergonomic power-bank/external-charger we’ve seen but definitely one of the innovative, ambitious sorts. The Double E power bank turns motion into energy with its internal dynamo. Give it a few good shakes and you’ve got juice for your phone or tablet!
Of course you can charge it the traditional way too (via MicroUSB), but that’s too boring. The form-factor features a cylinder with an intersecting cuboid. On the front of the cuboids are two outputs and one input. It also has an LED matrix that displays the power bank’s battery in a percentage format so you can see the power build up when you shake the gadget around, and watch the power drain when you’ve got a phone plugged into it.
Not the smallest power bank we’ve seen, the Double E’s size comes from the fact that it has a moving magnet and a copper coil on the inside to generate electrical energy. check out a couple pictures of it below
