The Charge Battery is an imaginatively named design that lets you recharge your batteries on-the-go. The design uses kinetic energy in the form of a winding spring to recharge your battery when the power goes low.
The Charge Battery is simple to use; all you need to do to recharge it is twist the positive side in a clockwise motion. The twisting motion on the spring causes energy to build up and that energy is then released back into the battery as the spring unwinds.
Rechargeable batteries are not only good for consumers, they're good for the environment. Many people still use single-use batteries, however, and that could be because powering up rechargeable batteries can be a pain. A simple concept like the Charge Battery could go a long way in making consumers happy and making the world a greener place.
