An apparatus for controlling a power distribution to devices has a power inlet to be connected to a power source, a primary power outlet to be connected to a primary device, at least one secondary power outlet to be connected to at least one secondary device, a sensing unit for sensing when a current level falls below a threshold in response to the primary device being turned off and when the current level raises above a threshold in response to the primary device being turned on, and an executing unit operatively connected with the sensing unit and operative for interrupting a power supply to the at least one secondary power outlet when the sensing means sense the current level below the threshold and supplying power to the at least one secondary power outlet when the sensing means sense the current level above the threshold correspondingly, the sensing unit being formed as a high frequency current sensing coil.
