4. Safety Instructions

Please read and understand all safety warnings and instructions before using this product to prevent injury or damage.

• Power Level: Ensure the device's power level is above 75% before using the jump starter function.
• Correct Connection: Always connect the red clamp to the positive (+) terminal and the black clamp to the negative (-) terminal of the battery. Do not reverse the polarity or allow the clamps to touch each other.
• EC5 Plug: Ensure the EC5 plug (smart ignition clip) is fully inserted into the starter power connector. Improper insertion can affect performance and may damage the interface.
• Jump Start Frequency: Do not attempt to jump-start the car continuously at high frequency. Allow at least 30 seconds between attempts. If the car does not start after three attempts, stop and seek professional assistance to avoid damaging the product.
• Car Environment: When jump-starting, ensure the car doors are closed and all electronic devices are turned off.
• Disconnection: Disconnect the jump starter from the car battery within 30 seconds after the car engine starts. Always unplug the EC5 connector from the device first, then remove the battery clamps.
• Overload Protection: Avoid using electrical appliances or loads that exceed the product's output current. This will trigger circuit protection and stop output.
• Physical Impact: Avoid strong physical impacts, such as knocking, throwing, trampling, or squeezing.
• Age Restriction: This product is not a toy. It is recommended for users aged 16 years or older. Keep children at a safe distance during operation.
• Storage: Store the product in a dry, clean environment, away from high temperatures, high humidity, strong light, and strong magnetic fields. Do not place it near fire or in other harsh environments.
• Water Exposure: The product is not waterproof. Do not rinse it with water or immerse it.
• Inflation Safety: High-pressure gas generates heat during inflation. Never insert the air tube into the mouth, ears, or eyes of people or animals.
• Cooling Down: To ensure optimal performance and extend product life, allow the device to cool down for 5 minutes after every 10 minutes of inflation. If noise or high temperature occurs during inflation, turn off the device immediately and let it cool for at least 15 minutes. Be cautious of hot hands when removing the air tube.
• Maintenance Charging: If the product is not used for a long time, charge and discharge it at least once every three months to maintain battery health.
• Disassembly: Non-professionals are strictly prohibited from disassembling this product.

6. Operating Instructions

6.1. Jump Starting a Vehicle

Follow these steps to safely jump-start your vehicle:

1. Prepare the Device: Open the carrying case and retrieve the jump starter and battery clamps.
2. Check Power Level: Short press the Power Switch (3) to turn on the device. Check the display (1) to ensure the power level is sufficient (recommended above 75%).
3. Connect Clamps to Device: Connect the battery clamps to the EC5 Interface (9) on the jump starter. Ensure it is fully inserted.
4. Connect to Car Battery:
   • Attach the red clamp to the positive (+) terminal of the car battery.
   • Attach the black clamp to the negative (-) terminal of the car battery.

   Important: Do not reverse the polarity or allow the clamps to touch each other.

5. Start the Car: Get into the car, close the doors, turn off all electronic devices, and then turn the ignition key to start the engine.

6. Disconnect: Once the car engine starts, immediately remove the jump starter. First, unplug the EC5 connector from the device, then remove the battery clamps from the car battery. This should be done within 30 seconds.

Troubleshooting Tip for Jump Starting:

• If the car doesn't start on the first attempt, wait at least 30 seconds before trying again. You can press the power button 2-3 times more to reset if needed.
• If the smart battery clip has indicator lights, red and green flashing indicates normal operation. A solid green light means it's ready to start. A solid red light or red and blue flashing means it cannot be operated.
• If using ordinary battery clips without indicator lights, do not clip the positive and negative poles together.
• If jump-starting is unsuccessful after a few attempts, remove the battery clamps, wait one minute, and try again. Do not continuously crank the engine for more than five seconds to prevent damage.

6.2. Inflating Tires

Use the built-in air compressor to inflate tires:

1. Connect Hose: Screw the braided air pump tubing into the Inflatable Hose Socket (10) on the device.
