A lot of small household appliances take dry batteries as their power supplies. However, most of them (e.g. telecontroller) dont need power unless they are in use, and will consume very little power at a time. Keeping batteries in the appliances for a long time will not only cause loss of energy but also lead to leakage of harmful chemicals in the batteries. GREENPOWER achieves conversion from kinetic energy to electrical energy according to the principle that cutting magnetic lines will induce current. When appliances are in use, the users operations (e.g. swing) will drive the magnet inside to cut the magnetic lines to produce current.
