One of the biggest problems we face with our gadgets and gizmos is their ability to stay charged up during the day. Mainly our phones, because they hold all of our conversations, games, contacts, and social media apps. Solar and wind power can cut it most of the time, but they are dependent on the weather to be amicable. If you want a bit more reliable source of energy, why not look towards yourself?

The nPower PEG (Personal Energy Generator) will let you charge your devices just by moving around. You simply toss it in your bag, put it on your bike, or take it on a walk and you’ll be able to charge your phone in no time. While it does harvest kinetic energy, you can juice it up through USB if you’re stuck at a desk. This will cost you around $130, but will be useful in any situation ranging from the wilderness to a busy city. Additionally, there are adapters that cost $12 should the included cables not fit your needs.
