3. Setup

3.1 Initial Charging

Before first use, fully charge the device using the provided USB-C charging cable. It is recommended to charge the device every six months to prolong battery life, especially if not used for extended periods.

To power on the device, press and hold the main switch for a few seconds. The display will illuminate. To power off, press and hold the main switch again.

4. Operating Instructions

4.1 Jump Starting a Vehicle

1. Ensure the jump starter is adequately charged.
2. Connect the heavy-duty smart jumper clamp to the jump starter unit. Ensure it is fully inserted.
3. Attach the red clamp to the positive (+) terminal of the vehicle battery.
4. Attach the black clamp to the negative (-) terminal of the vehicle battery. The smart clamp will indicate a successful connection (e.g., a steady green light). If an incorrect connection is made, an alarm will sound, and a red light will appear, indicating reverse polarity protection is active.
5. Start your vehicle's engine.
6. Once the engine starts, immediately remove the jumper clamps from the vehicle battery, then disconnect the smart clamp from the jump starter unit.

4.2 Inflating Tires

1. Screw the inflatable pump hose into the designated port on the jump starter unit.
2. Attach the other end of the hose to the tire valve. Ensure a secure connection.
3. Power on the device. The display will show the current tire pressure.
4. Use the mode button to select the appropriate inflation mode (car, motorbike, bike, ball, custom).
5. Use the '+' and '-' buttons to set the desired target pressure.
6. Press the main switch to begin inflation. The compressor will automatically shut off once the preset pressure is reached.
7. Disconnect the hose from the tire valve and the unit.

Note: The air compressor generates heat during operation. If used continuously for 6 minutes or if the temperature becomes too high, allow the air pump to rest for at least 15 minutes before resuming operation.

4.3 Portable Mobile Power

The device can function as a power bank to charge mobile phones, tablets, cameras, and other mobile devices via its USB ports. Connect your device using a compatible USB cable.

Note: Portable charging is standard speed, not fast charging. This feature is designed for emergency charging to preserve the main jump-start and inflation functions.

5. Maintenance

• Store the device in a dry place, away from water or rain.
• If not used for a long time, it is recommended to charge the device every six months to prolong battery life.

6. Troubleshooting

• Device not turning on: Ensure the device is charged. If charging, check for excessive heat, which may indicate a faulty charging cable or unit.
• Jump starter not working: Verify that the smart jumper clamps are correctly connected to the battery terminals (red to positive, black to negative). The smart clamp has anti-reverse polarity protection and will signal an incorrect connection.
• Air compressor overheating: If the air pump is used continuously for 6 minutes or if the temperature is too high, allow it to stop for at least 15 minutes before resuming operation.
• Tire over-inflation: The air compressor features an automatic shut-off function to prevent over-inflation once the preset pressure is reached.
