Operating Instructions

Jump Starting a Vehicle

The Doorii jump starter is designed for safe and efficient vehicle jump-starting. The smart jumper cables include built-in 9 protections and visible alarms to prevent incorrect operation and sparks.

1. Insert the Jumper Cable: Plug the blue end of the smart jumper cable into the jump starter's port. Ensure a secure connection.
2. Connect Clamps to Battery: Attach the red clamp to the positive (+) terminal of your car battery and the black clamp to the negative (-) terminal. The smart cables will indicate a correct connection (green light) or an error (flashing red).
3. Start Your Car Engine: Once the connection is confirmed as correct, start your car's engine.
4. Remove Jumper Cables: After the engine starts, immediately remove the jumper cables from the car battery, then disconnect them from the jump starter.

Maintenance

To ensure the longevity and optimal performance of your Doorii Portable Car Jump Starter, follow these maintenance guidelines:

• Regular Charging: Although the jump starter can standby for about 24 months, it is highly recommended to check and recharge the unit monthly to ensure it remains fully charged and ready for use. Lithium batteries can discharge over time, and a depleted battery may not perform as expected when needed.
• Proper Storage: Store the jump starter in its provided storage case in a cool, dry place, away from direct sunlight and extreme temperatures. Avoid storing it in places where it might get wet.
• Cleanliness: Keep the unit and its ports clean and free from dust and debris. Use a soft, dry cloth for cleaning.
• Handle with Care: While designed to be durable, avoid dropping the unit or subjecting it to strong impacts.

Troubleshooting

If you encounter issues with your Doorii Portable Car Jump Starter, please refer to the following common problems and solutions:

• Device not turning on or showing low battery:

  Ensure the unit is fully charged. Connect it to a power source using the Type-C cable and allow 3-4 hours for a full charge. The LCD display should show the charging percentage.

• Car not starting after connecting jump starter:

  Check the connections of the smart jumper cables to the car battery terminals. Ensure they are securely attached to the correct positive (+) and negative (-) terminals. The smart cables have built-in protections and will indicate if the connection is incorrect or if there's an issue. If the unit beeps or flashes an overload light, it may indicate that the vehicle's battery is severely depleted or the engine size exceeds the jump starter's capacity (e.g., a very large diesel engine might require more power than the 2000A peak output can provide, especially if the battery is at very low voltage). Ensure the jump starter itself has sufficient charge (above 50% is ideal for reliable starting).

• Jump starter gets warm during use:

  It is normal for the unit to generate some heat during high-current discharge, such as during a jump start. However, excessive heat or a burning smell indicates a problem. Discontinue use immediately and contact customer support.
• USB charging not working:

  Ensure the jump starter has sufficient power. Try a different USB cable or device to rule out cable or device issues. Confirm the device is properly connected to the USB output port.
