Portable AC energy storage power supply with insertion detection function

The invention discloses a portable AC energy storage power supply with an insertion detection function, and the power supply comprises a socket which is internally provided with a plurality of metal pins, and the metal pins are used for plugging contact pieces of a plug; a battery pack; an AC output module; the detection circuit module is connected with any metal pin and is used for outputting detection voltage; the detection voltage comprises a first voltage and a second voltage, the first voltage is a voltage detected by the detection circuit module after the plug is inserted into the metal pin, and the second voltage is a voltage detected when the plug is not inserted into the metal pin; the control module is used for controlling the alternating current output module to convert the direct current provided by the battery pack into alternating current to be output when the detected voltage is the first voltage; and when the detection voltage is the second voltage, the AC output module is controlled to stop o
