Abstract:
1. A variable power device for providing electrical devices connected thereto with a variable power signal, which comprises: at least one power outlet, an electrical device being connectable to the at least one power outlet; at least one current sensing circuit, the at least one current sensing circuit being electrically coupled to the at least one power outlet and sensing current flowing through the at least one power outlet and drawn by an electrical device connected to the at least one power outlet when the electrical device is in at least a standby mode and an active mode, and generating a feedback signal in response to the current sensed flowing through the at least one power outlet; and a power control circuit electrically coupled to the at least one power outlet and selectively providing one of a standby mode power signal and an active mode power signal to the at least one power outlet in response to the feedback signal from the at least one current sensing circuit, each of the standby mode power signal and the active mode power signal being an AC voltage greater than zero volts, the voltage of the standby mode power signal being less than the voltage of the active mode power signal, each of the standby mode power signal and active mode power signal not being a control signal and constituting power provided to an electrical device connected to the at least one power outlet.
