Abstract

A multi-functional charging device generally includes a housing having a lower housing and an upper housing. An electronic switching circuit is disposed within the housing. The lower housing is provided with an opening which has an inner housing socket attached to it. A pair of conducting plates in contact with the electronic switching circuit are attached to the inner housing socket. The inner housing socket is provided with a sliding socket and a coil spring is disposed between a sliding socket and the inner housing socket. The sides of the inner housing socket have a half shaft seat. The sides of the opening of the lower housing have a circular cutout. A pivoting hole is formed by the combination of the half shaft seat, the circular cutout and the circular shaft seat. A changeable plug can be received and installed within the pivoting hole. The changeable plug features a conducting terminal which can be contacted with the conducting plates when the plug is extended. The plug can be readily removed therefrom when the half shaft seat is separated from the circular cutout and the circular shaft seat. Another plug to match the particular specifications can be readily installed.
