The nPower® PEG is the world's 1st human-powered charger for hand-held electronics.
It uses the energy you generate while walking, running, or biking to charge your smart phone, music player, GPS, and other devices.
The PEG gives you access to backup battery power even when you're away from a wall outlet. As long as you're moving, your PEG is charging itself without any additional effort on your part. When your device needs a charge, just plug in to your PEG and press the button.
–Rain or shine, day or night, you'll have backup battery power.
