Check the vehicle’s cigarette lighter fuse, it should be rated at 15 A.
Ensure there is a secure connection between the power cord and the 12 V socket.
The preset tire pressure is lower than the current tire pressure. Increase the preset tire pressure to the manufacturer-recommended level.

Tire inflater is operating abnormally

The inflation nozzle is not properly connected to the tire’s valve stem.
Ensure there is a strong connection between the power cord and 12 V socket.
The preset tire pressure is lower than the current tire pressure.
Increase the preset tire pressure to the manufacturer-recommended level.

Air leaking through the hose
Ensure there is a strong connection between the inflation nozzle and valve stem.
