A fall-off protection and reverse-connection protection system and method for a connecting clamp of an automobile starting power supply. The system has an internal battery, a switching circuit, an access device, a connecting clamp, an MCU control circuit, a voltage division circuit for external battery detection, an output connecting clamp current detection circuit and an anti-reverse-connection protection circuit. In the method, voltage conditions of an external power supply can be effectively detected and different operating actions are taken based on the voltage conditions of the external power supply, thus ensuring normal startup.
