A charging device for charging an electronic device can include a main body having a recess. First and second electrical cables can be disposed in the recess when in retracted positions, and the first and second electrical cables can extend outside of the main body when in extended positions. The charging device can have a cover that is movable between a closed position, which can cover the recess, and an open position, which can expose the recess to enable the electrical cables to move between the retracted and extended positions. The charging device can include a battery. Electrical power can be received via the second electrical cable for charging the battery. Electrical power can be output from the battery via the first electrical cable to charge an electronic device.
