5. Operating Instructions
5.1 Jump Starting a Vehicle
- Ensure the jump starter is at least 75% charged (three LED lights illuminated).
- Connect the smart jump cable to the jump starter's EC-5 port. Ensure a secure connection.
- Attach the red (+) clamp to the positive (+) terminal of the vehicle's battery.
- Attach the black (-) clamp to the negative (-) terminal of the vehicle's battery.
- Once the clamps are correctly connected, the indicator on the smart cable will show a solid green light, indicating it's ready to jump. If it shows a red light or flashes, refer to the troubleshooting section.
- Start your vehicle's engine.
- Once the engine starts, immediately remove the smart jump cable from the vehicle battery terminals, then disconnect it from the jump starter.

5.4 Powering 12V Auto Devices
Use the provided EC-5 cigarette lighter adapter to power 12V automotive accessories.
- Plug the EC-5 end of the adapter into the jump starter's EC-5 port.
- Plug your 12V device into the cigarette lighter socket of the adapter.
- Ensure the device's power consumption does not exceed the jump starter's output limits (12V-16V/8A).
6. Safety Precautions
Always observe the following safety guidelines when using the jump starter:
- Do not attempt to jump-start a vehicle if the jump starter's battery level is below 75%.

- Do not expose the product to extreme temperatures (above 60°C/140°F or below -20°C/-4°F).
- Do not immerse the product in water, despite its IP67 rating, to prevent damage.
- Keep out of reach of children.
- If the jump starter becomes excessively hot during use, disconnect it immediately and allow it to cool down.
- Do not attempt to disassemble or modify the unit.
- Remove the jump starter from the vehicle battery within 30 seconds after the engine starts.
