1. A portable standby starting device for a vehicle, comprising a battery circuit, a reverse connection short-circuit detecting circuit, and a vehicle starting circuit, wherein the battery circuit is coupled to the reverse-connection short-circuit detecting circuit and the vehicle starting circuit, and is configured to supply power to the reverse-connection short circuit detecting circuit and the vehicle starting circuit;
the reverse-connection short-circuit detecting circuit is coupled to the vehicle starting circuit, and is configured to detect whether the vehicle load is in a reverse-connection state or a short-circuit state, and control the vehicle starting circuit to be prohibited from outputting a vehicle starting current when the vehicle load is in the reverse-connection state or the short-circuit state;
when the vehicle load is in the reverse-connection state, no microprocessor is involved in controlling the vehicle starting circuit; and
the battery circuit comprises a battery and a voltage regulating circuit;
the portable standby starting device for a vehicle further comprising a load access detecting circuit, wherein the load access detecting circuit is coupled to the vehicle starting circuit, and is configured to detect whether the vehicle starting circuit is connected to the vehicle load; and the load access detecting circuit, when detecting that the vehicle load is not connected, controls the vehicle starting circuit to be prohibited from outputting the vehicle starting current;
wherein the load access detecting circuit comprises a microprocessor, wherein the microprocessor is coupled to the vehicle starting circuit, and when the load access detecting circuit detects that the vehicle load is not connected, the microprocessor controls the vehicle starting circuit to be prohibited from outputting the vehicle starting current.
