| Compressor does not turn on. | No power from 12V outlet; Blown fuse in vehicle or compressor. | Check 12V outlet for power; Inspect and replace vehicle's cigarette lighter fuse or compressor's internal fuse (if accessible and user-serviceable). Ensure vehicle engine is running. |
| Compressor runs but does not inflate. | Hose not securely attached; Leak in hose or nozzle; Valve stem issue. | Ensure hose is tightly screwed onto compressor and valve stem; Check hose and nozzle for damage; Inspect valve stem for blockages or damage. |
| Compressor inflates too slowly. | Low power supply; Compressor overheating. | Ensure vehicle engine is running for optimal power; Allow compressor to cool down if it has been running for an extended period. |
| Inaccurate pressure reading. | Loose connection; Sensor malfunction. | Ensure the hose is tightly connected to the valve stem. If the issue persists, contact customer support. |
