7. Operating Instructions
7.1. Jump Starting a Vehicle
Ensure the jump starter has at least 50% charge before attempting to jump start a vehicle.
- Connect the smart jumper cable to the jump starter's dedicated port.
- Connect the red clamp (+) of the smart jumper cable to the positive terminal (+) of the vehicle's dead battery.
- Connect the black clamp (-) of the smart jumper cable to the negative terminal (-) of the vehicle's dead battery.
- Ensure the connections are secure and free from corrosion.
- Once connected, the smart jumper cable's indicator light will show its status (refer to the smart cable's manual for specific light indications).
- Start the vehicle's engine.
- Once the vehicle starts, immediately remove the smart jumper cable's black clamp (-) from the battery, then the red clamp (+).
- Finally, disconnect the smart jumper cable from the jump starter.
7.2. Inflating Tires and Other Items
The built-in air compressor can inflate tires and other inflatables up to 150 PSI.
- Connect the air pump hose to the inflation port on the jump starter.
- Attach the appropriate gas nozzle to the air pump hose for the item you wish to inflate.
- Connect the nozzle securely to the tire valve or inflatable item.
- Turn on the jump starter. The LCD will display the current pressure.
- Use the control buttons to select the desired inflation mode (cars, bikes, motorcycles, balls) or manually set the target pressure and unit (BAR/PSI/KPA/kg/cm²).
- Press the start button to begin inflation. The compressor will automatically stop once the preset pressure is reached.
- Disconnect the nozzle and air pump hose.
7.3. Using as a Portable Power Bank
The M-JA1 can charge your electronic devices via its USB-A and Type-C ports.

9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on. | Battery is completely discharged. | Charge the device using the Type-C charging cable. |
| Vehicle does not jump start. | Battery level too low (<50%). Incorrect cable connection. Vehicle battery severely damaged. | Ensure device is charged above 50%. Verify correct polarity (+ to +, - to -). Consult a professional mechanic. |
| Air compressor not inflating. | Hose not securely connected. Target pressure not set. Battery level too low. | Ensure air pump hose and nozzle are tightly connected. Set desired PSI/BAR on the LCD. Charge the device. |
| Device is overheating. | Prolonged use or internal issue. | Immediately stop use, disconnect all connections, and allow to cool down in a safe, non-flammable area. If issue persists, contact support. |
10. User Tips
- Always ensure the jump starter's power is greater than 50% before attempting to jump start a car for optimal performance and safety.
- Avoid jump starting a car when it is already under load (e.g., with headlights or radio on) to prevent unnecessary strain on the device and vehicle battery.
- For long-term storage, charge the device to between 50% and 80% capacity every three months to preserve battery health.
- If you notice any unusual heating during or after use, immediately cease operation and place the device in a safe, non-flammable location to cool down.
