AMPY: Power your devices from your motion

21. 10. 2014 | |

It started with a frustration we all have — a dead smartphone at the worst time. AMPY's co-founders -- Tejas Shastry, Alex Smith, and Mike Geier -- met in an

entrepreneurship class at Northwestern University during their engineering PhDs. As active urbanites, they wanted to capture the energy from our daily activities to charge their phones. They engineered a solution to do just that, creating the technology that powers AMPY (formerly known as myPowr).

AMPY is a wearable device that captures energy from your motion, turning it into power to charge your phone or any USB-powered device. AMPY captures your kinetic energy when you move and stores it, so you can recharge your smartphone when you need it the most. AMPY stores the energy you generate in the internal lithium ion battery. Simply plug in your smartphone or wearable device into the USB port to start charging. In a hurry? AMPY will charge your devices just as fast as a wall outlet. AMPY's internal battery stores about a week's worth of physical activity and stays ready to use for months. You can also recharge AMPY from a wall outlet if needed using the micro-USB port on top.
