Abstract
An extension cord includes a plurality of electrical conductors. A plug is configured to electrically couple a first respective end of the plurality of electrical conductors with an electrical receptacle of a power source. An outlet assembly is coupled with a second respective end of the plurality of electrical conductors. The outlet assembly may include one or more outlet receptacles configured to provide electrical power from the power source. A power meter may be configured to measure an electrical draw through the outlet assembly and to provide a user perceptible output based upon the measured electrical draw. A carbon monoxide monitor may be configured to detect an environmental carbon monoxide level proximate the outlet assembly and to provide a user perceptible indication when the detected environment carbon monoxide level exceeds a threshold.
