The Mint Energy rechargeable battery is an eco-friendly solution available to the masses that produce a lot of garbage every year from disposed batteries. Mint Energy, however, is unlike any other rechargeable battery as it does not need to be charged through an electrical socket.

To charge up this bad boy, all you have to do is give Mint Energy a swift shake and the battery will be good as new. This innovative battery uses an embedded magnet that moves between a coiled bobbin when it shakes.
