Energy-saving electrical adaptor

Abstract

A power conservation apparatus having a power inlet for providing power to the power conservation apparatus and an external appliance, a power outlet operable to be connected to the appliance, a relay coupling the power inlet and the power outlet, a current sensor operable to measure a current flow from the power outlet to the appliance, a threshold detector operable to receive an input in accordance with the current flow and operable to determine if the appliance is in a state of non-use, and a timer having a set-point; wherein the timer is activated upon the appliance entering the state of non-use and wherein the relay is opened upon the timer reaching the set-point, so as to prevent the power conservation apparatus and the appliance from drawing power from the power inlet. When in the “off” state, the AC power consumed by the apparatus and coupled appliances is zero.
