Abstract

A charger with replaceable electrical plugs includes a casing 1 including a lower casing 11 and an upper casing 12. An electronic power supply circuit 13 is accommodated inside the casing 1. The lower casing 11 has an opening 111 having a replaceable two prong electrical plug 14 pivotally disposed therein to adapt to different specifications of electrical sockets used in different countries. The power supply circuit 13 may convert AC into low voltage DC for use, through a cable 131, by small electrical appliances. The upper housing 12 is provided with a tubular recess 121 pivotally provided with a cigarette lighter plug 15 which may fit into a car's cigarette lighter socket. The power supply circuit 13 may transform the car's high voltage DC into a low voltage DC to provide electric power outdoors. The pivotally disposed plug 14 may be replaced with a non-pivotal plug 14' (FIG. 6). A rod 1722 may be depressed to disengage locking means 1721, 163 and then be moved transversely to cause joint movement of slide seat 17 and fastening piece 115 into position of locking or releasing one or the other of the plugs 14.
