Abstract: A mobile device charging apparatus includes a mobile device case including an electrical adapter configured to connect with a charging port of a mobile device. A gearbox is arranged in the case. The gearbox includes interconnected gears configured to generate electrical energy by rotating the interconnected gears. A mechanical crank is configured to rotate the interconnected gears of the gearbox to generate the electrical energy. A printed circuit board (PCB) is in electrical communication with the gearbox. The PCB is in electrical communication with the electrical adapter. A battery is in electrical communication with the PCB. The battery is configured to store the electrical energy generated by rotating the interconnected gears of the gearbox. The PCB is configured to charge the mobile device by transferring the stored electrical energy from the battery to the electrical adapter configured to connect with the charging port of the mobile device.
