The invention relates to an energy-saving power supply extension line, in particular to an energy-saving power supply extension line with a socket status notification and a remote control power-off function.

In order to meet the needs of the public, the design of most electrical appliances is becoming more and more human. Many appliances only need to press the power button of the remote control to achieve the purpose of power on or off.

However, this type of electrical appliance still needs to use a certain power standby even when it is turned off, in order to maintain the operation of the remote control receiver and the power control circuit. Long-term and large-scale accumulation, energy consumption and the loss of electricity costs are also considerable.

Some users turn off the power and pull the plug out of the socket after the appliance is used, so as to reduce energy waste. However, when you want to use the appliance again, you must plug the appliance into the power outlet.
