Safety Information
- This tire inflator operates on 12V DC power only, supplied via a car cigarette lighter socket. Do not attempt to power it directly through an AC wall outlet.
- The device does not contain an internal battery. It requires a continuous 12V DC power source during operation.
- After continuous operation for approximately 10 minutes, allow the air compressor to cool down for 10 minutes to prevent overheating.
- Ensure the air hose connection is secure to prevent air leaks during inflation.
- Keep out of reach of children.
- Do not leave the inflator unattended while in use.
