Methods and apparatus for providing electrical energy to an electrical circuit without using a pronged plug are disclosed. A power connector includes a substrate with openings for receiving prongs of an electrical plug. Contacts supported on the substrate extend into the openings. The contacts are connected to the electrical circuit. The substrate is placed over an electrical outlet receptacle. When the prongs of the electrical plug are inserted through the two openings of the power connector and into the outlet receptacle, the prongs touch each of the contacts, respectively, such that electrical power can be supplied to the electrical circuit connected to the pair of contacts. The power connector can be incorporated into a wall plate mounted over an electrical outlet, either in place of or directly over an existing wall plate. An electrical circuit is housed within the wall plate. Typical electrical circuit devices powered by the present invention include night lights, emergency lights, air fresheners, air purifiers, pest controls, alarms, smoke detectors, carbon monoxide detectors, amplifiers, antennae, motion sensors, home security modules, home automation modules, surge protectors, electronic filters, load indicators, and home-wiring based network connections for telephones or local area networks (LANS).
