Ampy is a battery that charges itself from the energy your body creates through motion. An app on your smartphone indicates the amount of power you have generated for the Ampy while tracking the number of calories you burned. The Ampy is able to charge any device that uses a USB port. The company behind Ampy is currently seeking funding and is scheduling to bring the product to the market by June 2015. The price for the Ampy battery is set to retail for $95. Additional accessories will include a clip, sleeve and a strap for easier wearability.
