Meet the AMPY charger: an innovative device that generates power for your smartphone or other USB-powered devices as you move. It captures energy from your motion and turns it into power to charge your gadgets. The device is compact and wearable. All you need to do is connect your gadget to the USB port to start charging. AMPY’s internal battery stores about a week’s worth of physical activity. The accessory kit lets you wear your Ampy how you like.
AMPY has an app that lets you know how many calories you have burned and how much energy you have generated. Like what you see? You can get this on Kickstarter.
