7. Troubleshooting
Common Issues and Solutions
| Problem | Possible Cause | Solution |
|---|---|---|
| Jump starter does not turn on/low power | Insufficient charge; "virtual power" from long shipping | Fully charge the unit for 4-5 hours before first use. |
| Vehicle does not start | Incorrect clamp connection; severely dead battery | Ensure clamps are connected correctly (red to positive, black to negative). Check for secure connection. |
| Error message on LCD screen | Connection issue; internal fault | Refer to the smart clamp's built-in 8 protections and visible alarms for specific error codes. Disconnect and reconnect. If issue persists, contact customer support. |
