If your air compressor is not filling up your tire, there could be a few potential reasons:
Leak or Valve Issue: Check for any leaks around the valve stem or the connection between the adapter and the valve. Ensure the valve is properly closed.
Inadequate Pressure: Make sure the compressor is set to the correct pressure, and that the pressure gauge on the tire inflator is calibrated accurately.
Power Source: Ensure that you have selected the appropriate power source (e.g., 110V AC, 12V DC, or battery) and that it is functioning correctly.
Defective Components: It's possible that a component of the air compressor, such as a motor or pressure sensor, is not functioning properly.
Overheating: Some compressors may shut off if they become too hot. Give the compressor time to cool down before attempting to use it again.
