A cord-reel assembly mounted within a wall and powered by an in-wall electric power line or an adjacent wall socket. The cord-reel assembly includes a reel rotatably supported within a housing and an extension cord wound on the reel. An electrical socket is located on one end of the extension cord. The extension cord unwinds from the reel to position the electrical socket at locations remote from the housing. In alternate installations, a cover plate jointly covers the cord-reel assembly and the adjacent wall socket. The cover plate also electrically couples the cord reel assembly to the wall socket. Additional features such as an on/off switch, surge protection and surge indicator may also be provided on the cover plate.
