The invention mainly provides a charging device of a mobile electronic device. The charging device mainly comprises a bridge rectifier unit, an input end filter unit, a voltage converter, a power switch assembly, a rectifier filter unit, an output end filter unit, a voltage detection unit, a control unit and an optical coupler. The input end filter unit comprises two first input capacitors, a second input capacitor and a change-over switch, each first input capacitor has a first capacitance value, and the second input capacitor has a second capacitance value larger than the first capacitance value. Through the design, the control unit can control the switching-on and switching-off of the change-over switch, so that the input end filter unit simultaneously uses the two first input capacitors and the second input capacitor to carry out filtering operation or only uses the two first input capacitors to carry out filtering operation according to the change of a rated voltage of an alternating current electric sig
