An receptacle device with power-meter is provided. The receptacle device includes a power supply conversion unit configured to convert input power supply so as to measure a current value or a voltage value of the input power supply; an analog-to-digital conversion unit configured to convert an analog output from the power supply conversion unit into a digital signal, a control unit configured to output a control signal to control operation of the receptacle device by comparing the digital signal input from the analog-to-digital conversion unit to a predefined reference value; a switch unit configured to be turned on or off in response to the control signal from the control unit; and a display unit configured to display values of current, voltage, power, zero phase, and power factor of the input power supply, and display a menu that is controllable by a user.
