Apparatus and methods to wirelessly charge batteries within a radius of a power source. A power transmitter generates a power signal of specific configuration which is received by the power charger. The power charger harvests the received power signal and stores the energy contained within for the purpose of charging target battery or batteries. The typical uses of this invention are but not limited to the home, car, office, and work place. Anywhere where rechargeable batteries are used in a device where they need to be placed or physically removed from the device for recharge by conventional wired chargers, this invention provides method to prolong battery life in such a way to extend the time between a physical wired recharge or eliminate such events all together.
