When a load is inserted into the socket, the relay module makes the output interface powered on, and further the load can be charged. The power quantity acquisition module transmits the power quantity signal to the MCU module in real time. When the power quantity reaches the threshold value of full charge of the load, the MCU module controls the relay module to automatically disconnect, so as to cut off the power of the output interface and the load, accurately and error-free automatically cut off the power, effectively avoiding the phenomena of fire, battery bulging and shortening of battery charging life caused by long-term charging, and improving the safety of residents' electricity use.

[0009] A power quantity acquisition module, which is used for feeding back the power quantity signal of the accessed load to the MCU module in real time.
[0010] Adopting the above technical solution, when a load is inserted into the socket, the relay module makes the current output module powered on, and further the load can be charged. The power quantity acquisition module transmits the power quantity signal to the MCU module in real time.
