Abstract: A jacket device is configured to be used with a mobile communication device. The jacket device includes a sidewall and a baseplate, wherein the sidewall and the baseplate cooperate to form a receiving chamber for receiving the mobile communication device. The jacket device also includes a rocker bar having a pressing portion connected to a rack portion, wherein the rack portion extends through the sidewall. A transmission is disposed on the baseplate and connected with the rocker bar. An electric generator is disposed on the baseplate. An electric generator includes a rotor coupled with the transmission and a stator fixed on the baseplate. When the pressing portion is pressed, the rack portion drives the rotor to rotate via the transmission so that electric power is generated by the electric generator.
