9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Vehicle does not start | Low charge on jump starter; incorrect clamp connection; vehicle battery severely discharged or damaged; engine size exceeds capacity. | Ensure jump starter is fully charged. Verify correct clamp polarity (+ to +, - to -). Check vehicle battery condition. Confirm engine size is within 8.0L Gas / 7.0L Diesel limits. |
| Smart jumper cable indicator is red or flashing | Incorrect connection; short circuit; reverse polarity; over-temperature. | Disconnect and re-connect clamps correctly. Ensure clamps do not touch. Allow unit to cool down if hot. |
| Device not charging | Faulty cable or adapter; charging port issue. | Try a different USB-C cable and wall adapter. Ensure cable is fully inserted into the Type-C input port. |
| Wireless charging not working | Device not Qi-compatible; incorrect placement; foreign objects. | Ensure your device supports Qi wireless charging. Re-position the device on the charging pad. Remove any metal objects between the device and the pad. |
10. User Tips
- Verify Engine Compatibility: The UTRAI JS-1 PRO is powerful enough for most passenger cars and motorcycles, including those with 8-cylinder engines, provided they are within the 8.0L gas or 7.0L diesel limits. Always check your vehicle's engine displacement before attempting a jump start.
- Cold Weather Performance: This unit is designed to operate effectively even in temperatures as low as -20°C. For best results in extreme cold, ensure the jump starter is fully charged and kept as warm as possible before use.
- Regular Recharging: To maximize the lifespan and readiness of your jump starter, make it a habit to recharge it every few months, even if it hasn't been used. This prevents deep discharge and maintains battery health.
