Abstract

A charging device for recharging a battery includes an electric energy generating module, a voltage regulating module, and a battery electrically connected. The electric energy generating module converts kinetic energy into electric energy and outputs an unstable voltage. The voltage regulating module stabilizes the unstable voltage into stable voltage. The charging circuit outputs the stable voltage to the battery.
