Abstract: An electric outlet power control device includes an electric outlet strip having female receptacles for providing electricity to a host computer and computer peripheral apparatuses, and a control module having a sensor for sensing the current signal of the host computer and an electric switch member controllable by the sensor to cut off power supply from all the female receptacles when the host computer is off.

Abstract: A power control module installed in the power supply device of a computer for power control is disclosed to include an electric switch member for switching on/off power supply conduction between the power supply device and the motherboard of the computer, and a sensor for sensing the power-on/off current signal of the motherboard of the computer and driving the electric switch member to switch off power supply conduction between the power supply device and the motherboard of the computer when the user switched off the computer after work.

Abstract: A mobile power adapter having an electric socket for power input, multiple adapter ports for power output, a power supply unit for converting input power supply into desired output power supply for output through the adapter ports, and a monitoring unit for monitoring the temperature inside the mobile power adapter and the operation status of the power supply unit on electric voltage, electric current, power consumption status and total wattage for enabling the monitoring data to be displayed on a display screen on the outside wall of a housing of the mobile power adapter.
