Commodity anti-theft alarm method without alarm circuit detection

The invention provides a commodity anti-theft alarm method without alarm circuit detection, which relates to the technical field of commodity anti-theft alarm, and comprises the steps of electrically connecting a software anti-theft app and a management end app through a power supply and a commodity, pre-installing an app alarm end on the commodity, identifying charging information, starting defense organization after charging is detected, and starting alarm after power failure. An alarm circuit and an expensive manufacturing process thereof are directly canceled, the adapter is connected to the commodity for charging through the power supply connecting line, and after the commodity is electrically connected with the adapter, charging current or voltage is identified, and a charging signal is fed back to an app alarm end, so that anti-theft detection of the commodity is realized, alarm circuit detection is not needed, and after the power supply is electrically connected with the commodity, the charging signal
