- Check Indicator: The smart jumper cable indicator light will show green if the connection is correct and safe to proceed. If it shows red or flashes, check the connections and ensure there are no issues like reverse polarity.
- Start Vehicle: Once the indicator is green, start your vehicle's engine.
- Remove Clamps: After the vehicle starts, immediately remove the jumper clamps from the vehicle battery, then disconnect the clamps from the jump starter.
6.2 Using as a Portable Power Bank
The jump starter can charge various electronic devices via its USB and Type-C ports.

7. Maintenance and Storage
- Cleaning: Wipe the unit with a dry, soft cloth. Do not use harsh chemicals or abrasive materials.
- Charging: Recharge the unit every 3-6 months to prolong battery life, even if not used.
- Storage: Store the jump starter in a cool, dry place, away from direct sunlight and extreme temperatures. The unit is designed to operate in extreme temperatures (-4°F to 140°F / -20°C to 60°C), but for long-term storage, room temperature is ideal.

8. Troubleshooting
- Unit does not turn on:
- Ensure the unit is charged. If not, connect it to a power source using the USB-C cable.
- Vehicle does not start after jump-starting:
- Check that the jumper clamps are securely connected to the correct battery terminals. Ensure the jump starter has sufficient charge. If the vehicle still doesn't start after a few attempts, there might be a larger issue with the vehicle's battery or engine.
- Smart clamps show a red or flashing light:
- This indicates an incorrect connection (e.g., reverse polarity) or a fault. Disconnect the clamps and re-attach them carefully, ensuring red is to positive (+) and black is to negative (-).
- Device not charging from power bank ports:
- Ensure the jump starter has enough charge. Check the charging cable and the device's charging port for damage. The unit automatically turns off when not in use, so ensure it's active when connecting a device.
