Save money when charging. Get free and convenient energy charge from everyday activities.

Your device is charged by induction when you are riding your bike, taking a walk with your pram or using the items on the playground. Magnets and coils produce the energy. The technology is well-known.
Use your own energy and save money with: POWER MAKER
