ABSTRACT:
An extension cord assembly has a housing composed of a front casing and a rear casing, and two bases respectively and rotatably provided at opposite sides of the housing, wherein each base has multiple sockets formed thereon. Since the bases are rotatable, the base is able to be turned to a desired position to allow any plug to be easily inserted into the sockets on the bases.
