3. Setup and First Use
3.1. Jump Starting Your Vehicle
Before jump-starting, ensure the device's power level is sufficient (more than 75% recommended).
- Connect Clamps to Device: Insert the battery clip into the EC5 connector of the product.
- Connect Clamps to Car Battery:
- Fully clamp the red clip to the positive (+) terminal of the car battery.
- Fully clamp the black clip to the negative (-) terminal of the car battery.
WARNING: Do not connect the positive and negative terminals inversely. Do not allow the two clips to touch each other. Ensure proper polarity to avoid danger.
- Start Vehicle: Get in the car, turn on the ignition, and ensure all electronic devices are off and doors are closed.
- If Car Fails to Start: If the car does not start on the first attempt, wait 5 seconds, then try again. You can press the start button 2-3 times more, with a 5-second interval between attempts. If the car still doesn't start after three consecutive attempts, stop trying to avoid damaging the product.
- Disconnect Device: Once the vehicle is started, remove the product within 30 seconds. First, unplug the battery clip from the EC5 port on the device, then remove the positive and negative battery clamps from the car battery.

3.2. Tire Inflation
- Attach Inflatable Hose: Screw the inflatable hose onto the device's inflatable hose socket.
- Connect to Tire Valve: Snap the other end of the hose onto the tire valve.
- Turn On Device: Long press the "On/Off" button for 3 seconds to turn on the product. The screen will automatically display the current tire pressure.
- Select Mode and Set Pressure: Short press the "Mode Adjustment" button to switch to the desired inflation mode (Car, Motorcycle, Bicycle, Basketball). The default car tire pressure is 2.5 Bar. Use the "+" or "-" buttons to adjust the target air pressure value.
- Start Inflation: Press the "On/Off" button again to start the inflatable pump.
- Automatic Stop: The pump will automatically stop when the air pressure reaches the preset value. Alternatively, press the "On/Off" button again to stop inflation manually.
- Disconnect Hose: After the air tube cools down, remove it from the car tire and the device.
Warm Reminder:
During the inflation process, the tire pressure value will be displayed in real-time. There is no need to constantly monitor it, as the device will automatically stop when the target pressure is reached.

7. User Tips
- Charge Fully Before First Use: Always ensure the device is fully charged before its initial use and before any critical operation.
- Keep Warm in Cold Weather: For optimal performance, especially in very cold conditions, keep the jump starter warm (e.g., inside the car cabin) before use.
- Jump Start Procedure: When jump-starting, connect positive to positive and negative to negative. Crank the engine for no more than 3 seconds. Allow 2-3 minutes between attempts for the internal batteries to cool down.
- Tire Inflation: The compressor will automatically stop once the preset pressure is reached, so you don't need to constantly monitor it.
- Check Power Level: Always check the power level before using the jump starter function; a minimum of 75% charge is recommended.
8. Important Safety Warnings
- Do not use the emergency starting power to continuously start the car at high frequency. The time interval between two ignitions must be more than 30 seconds.
- If the car cannot start after three consecutive attempts, stop trying to avoid damaging the product.
- Avoid using electrical appliances or loads that exceed the product's output current. This may trigger circuit protection or cause the product to have no output.
- Avoid strong physical impacts such as knocking, throwing, trampling, or squeezing.
- This product is not a toy. Keep out of reach of children. It is recommended for users aged 16 or older. Maintain a safe distance between children and the product during use.
- To prolong the product's lifespan, if not used for a long time, charge it at least once every three months.
- Use the device in a dry and clean environment. Mud and dust can cause damage. The product is not waterproof; do not rinse with water.
- High-pressure gas generates heat during inflation. Never insert the air tube into the mouth, ears, or eyes of people or animals to prevent injury.
- To ensure proper function and extend lifespan, after 10 minutes of inflation, let the machine stop for 5 minutes to cool down before reusing. If there is noise or high temperature during inflation, turn off the machine immediately and let it cool for at least 15 minutes. Be careful of hot hands when removing the air tube.
- Ensure the EC5 plug (smart ignition clip) is fully inserted into the starter power connector. Improper insertion can affect starting performance and may seriously melt the plastic part of the interface.
- Non-professionals are strictly prohibited from disassembling this product.
