The invention discloses air spring inflation equipment which comprises a connecting wire harness, a power module, a switch module and a protection circuit. The switch module comprises first switches for controlling on-off of electromagnetic valves of the vehicle and a second switch for controlling starting of an air compressor; the connecting wire harness is used for being connected with all electromagnetic valves and an air compressor of a vehicle. The positive electrode of the power module is connected with the first end of each first switch in the switch module, the second end of each first switch is connected with the input end of the protection circuit, and the output end of the protection circuit is connected to the power module. The protection circuits are in one-to-one correspondence with the first switches; each electromagnetic valve of the vehicle is connected to the protection circuit, and the protection circuit is used for enabling the voltage at the two ends of the electromagnetic valve to be at a preset holding voltage value after the first switch is closed and the electromagnetic valve is in an open state; and after the second switch is closed, the air compressor is started to inflate the air spring. The portable charging of the air spring is realized.
