Abstract
A fast charging device for mobile electronic device is disclosed. Particularly, an input-end filtering unit contained in the fast charging device is designed to comprise two first input capacitors, one second input capacitor, and one switch element. By such design, in case of a rated voltage of an input AC power being smaller than 110 Vac, the switch element is controlled to complete a switch-ON operation, so as to make the input-end filtering unit execute a signal filtering process by simultaneously using two first input capacitors and one second input capacitor. Moreover, in case of the rated voltage of the input AC power being in a range between 110 Vac and 264 Vac, the switch element is controlled to complete a switch-OFF operation, so as to make the input-end filtering unit execute the signal filtering process by merely using two first input capacitors.
