Abstract: Provided are a power monitoring apparatus of standby power saving type, an electric load device, and a power monitoring method. The power monitoring apparatus of standby power saving type includes: a power metering module measuring a power consumption situation of an electric load device, transmitting a measured result to a communication module, and switching off when a standby mode of the electric load device is held for more than a preset time or the electric load device is off; the communication module being supplied with power upon the switching-on, transmitting a power consumption value received from the power metering module to exterior, being supplied with standby power upon the switching-off to wait for receiving a call signal, and switching on a switch upon reception of the call signal; and a charging module starting charging upon the switching-on, and supplying standby power to the communication module upon the switching-off.
