Operating Instructions
Jump Starting a Car
Ensure the jump starter battery capacity is above 75% before attempting to jump start your car.
- Insert the plug of the battery clamps completely into the jump starter. The red and green lights will flash alternately.
- Connect the red clamp to the vehicle battery's positive (+) terminal and the black clamp to the negative (-) terminal. The green light should be always on.
- BOOST Mode: If the indicator light is still blinking red and green after the clip is connected to the vehicle battery, then press and hold the BOOST button on the side of the clip for 3 seconds. The indicator light will change to green and stay on, and you will enter the vehicle for ignition operation within 60 seconds.
- Start the vehicle.
- Once the vehicle is started, remove the battery clamp from the car battery and the jump starter.

If the engine does not start on the first try, disconnect the jump starter from the car battery and wait for at least 20 seconds before reconnecting.
Inflating the Vehicle Tire
Please read safety instructions carefully before use. For safety reasons, the device should be kept out of reach of children. Inspect the JS-30 Jump Starter before each inflation, ensuring the valve and the air hose are not damaged. Do not bend or restrict the air hose while the compressor is in use. Avoid using in rainy or wet conditions as water entering the unit can cause internal damage and premature failure. In case of an electrical or mechanical fault, immediately switch off and unplug the compressor. Only use on tires and inflatable items. Take extra care not to over-inflate when inflating other inflatable items such as sports balls, bike tires, air beds, etc.
- Press the Power button to activate the device. Then press the M button to switch the inflating modes. Each time you need to switch the air pressure unit, press and hold the M key for 2 seconds to change between PSI, BAR, KPA or kg/cm².
- Use the + / - buttons to increase/decrease the air pressure value until your desired air pressure is reached.
- Remove the dust cap from the tire valve. Carefully remove the air hose from JS-30 and connect it securely onto the tire valve, then press down the handle to fix the air hose. Once attached, your tire pressure will be displayed on the LCD display.
- Press the inflation button to start inflation. Press the button once again to stop inflation, or stop inflation automatically when it reaches the preset value. Then press the Power Button to turn off the device completely, disconnect the air hose, and replace the dust cap you have taken off.

Note:
- Check your car's standard tire pressure before you set your desired pressure. The standard tire pressure is usually displayed in the vehicle user manual, the label next to the cab door (near the B pillar), the drawer next to the driver's seat, the fuel door, etc.
- The high temperature will pressurize the tire, so please inflate when the tire cools.
- To extend the service life, please let the device rest for 10 minutes to cool down after continuous inflation.
Continuous Inflation Guidelines:
| Inflating Air Pressure Range | Maximum Duration of Continuous Inflating | Downtime |
|---|---|---|
| <38 PSI | 15 Minutes | 10 Minutes |
| 38 PSI-60 PSI | 8 Minutes | 10 Minutes |
| 60 PSI-110 PSI | 4 Minutes | 10 Minutes |
| 110 PSI-150 PSI | 2 Minutes | 10 Minutes |
