myPower (www.runwithmypower.com) is a fitness companion that clips to your hip and captures your kinetic energy as you move. myPower stores this energy so you can use it to charge your smartphone or other mobile device later in the day. 45 minutes of running, 50 minutes of cycling, or 90 minutes of walking with myPower can give your smartphone an extra 3 hours of battery life (for typical smartphone usage). Using myPower for a year can offset the carbon footprint of itself and the device you charge with it. Our companion smartphone app tracks your physical activity and energy generation, motivating you to stay fit and stay charged. At about half the size and weight of a smartphone, myPower is a convenient and stylish fitness tracking and energy generation platform.
