6.2. Using the Air Compressor

1. Step 1: Connect the detachable air hose to the air compressor port on the JS-30 unit and attach the appropriate valve connector to the item you wish to inflate (e.g., tire valve).
2. Step 2: Press the power button to turn on the device. Select the desired inflation mode (Car, Motorcycle, Bike, Ball, Custom) using the 'M' button. Long press the 'M' button to switch between pressure units (PSI, BAR, KPA, Kg/cm²).
3. Step 3: Use the '+' and '-' buttons to adjust the target air pressure. Press the inflation button (often indicated by a pump icon) to activate the air compressor. The device will automatically shut off when the target pressure is reached.

The air compressor is suitable for various items, including cars, motorcycles, bikes, and balls, with a maximum pressure of 150 PSI.

• Air Hose: Ensure the air hose and connectors are clean and free of debris before and after use.

8. Troubleshooting

8.1. Jump Starter Issues

• Vehicle won't start: Ensure clamps are securely connected to the correct battery terminals. Check if the jump starter is sufficiently charged. If the battery is deeply discharged, use the 'Boost Start Mode'.
• No power from jump starter: Ensure the device is turned on and charged. Check cable connections.

8.2. Air Compressor Issues

• Compressor not inflating: Check if the air hose is securely connected to both the device and the item. Ensure the correct pressure unit and target pressure are set. Verify the device is charged.
• Inaccurate pressure reading: Ensure the valve connector is properly sealed to prevent air leakage.

8.3. Power Bank Issues

• Devices not charging: Ensure the JS-30 is sufficiently charged. Check that the charging cable is properly connected to both the JS-30 and your device.

8.4. OBD Scanner Issues

• Cannot connect to app: Ensure Bluetooth is enabled on your phone and the OBD2 adapter is correctly plugged into the car's port. Restart the app and try again.
• No diagnostic data: Verify the car's ignition is on (engine can be off). Ensure the OBD2 adapter is firmly seated.

9. User Tips

• Always ensure the jump starter is fully charged before storing it in your vehicle for emergencies.
• Regularly check your vehicle's tire pressure using the air compressor, not just when they appear low, to maintain optimal fuel efficiency and tire longevity.
• Familiarize yourself with the YMBOD app and its diagnostic features before an emergency arises, so you can quickly identify and understand potential vehicle issues.
• Keep the insulated gloves readily accessible in the EVA protection case for safe handling during jump starts.
