PURPOSE: An outlet type power rate display device is provided to reduce energy consumption by directly confirming power rates, power consumption and the like with naked eye. CONSTITUTION: A plug unit(100) is coupled with an electrical outlet unit(120) connected to a power line so as to receive AC power. The electrical outlet unit outputs the AC power to electronic devices. A power conversion and supply unit(130) converts the AC power to DC power and rectifies the DC power. A power source measurement unit(140) measure the amount of current of the power source. A setup input unit(180) sets and inputs a target amount, a service life, a service fee or a remaining service fee. A memory unit(190) stores data values. A control unit(150) calculates a real-time amount and the remaining service fee. |
