In this paper a simple mechanical power driven battery charging system is introduced. Specifically, a hand driven system has been developed to charge a rechargeable battery for small scale electricity supply. Instead of using any fossil fuel the system can provide enough electrical energy to charge a battery for domestic applications. The charging unit can be used to provide limited electric supply in the remote and isolated areas where there is no national power grid connection. In addition, the system can be used in the emergency situation for mobile charging, indoor lighting and such applications.
