Ampy Kinetic Energy Charger
The concept of getting off our butts in order to charge our battery-operated devices is pretty brilliant. It’s combining what we need – movement, exercise – with what we want – a functioning smartphone – and it’s exactly what Ampy does.
This little battery booster captures energy from your motion and turns it into power to charge your USB devices. Whether you’re going hard at the gym or just walking around the house, any bit of energy you expend gets put into the juice pool. You can wear it on your arm or leg or just stick it in your pocket. The current iteration provides enough power for smartphones and most wearable devices, but not laptops or tablets yet. The accompanying app shows your stats like how many minutes of battery life you’ve generated and the amount of calories burned. [Purchase]
