Operating Instructions
1. How to Jump Start a 12V Vehicle
Note: Please ensure the correct connection of the vehicle battery before pressing the "BOOST" button on the jumper cable.
- Connect the Jumper Cable: Plug the smart jumper cable into the 12V Jump Start port on the GOOLOO A7. Then, connect the red clamp to the positive (+) terminal of the vehicle battery and the black clamp to the negative (-) terminal.
- Wait for Green LED: Once connected correctly, the green LED on the smart jumper cable will illuminate solid. If it's flashing or red, refer to the Troubleshooting section.
- Start Vehicle Engine: Start your vehicle's engine. If it doesn't start immediately, wait a few seconds and try again. Do not crank for more than 3 seconds per attempt.
- Disconnect: Once the engine starts, disconnect the jumper cable from the GOOLOO A7 and then from the vehicle battery.



2. How to Use the Tire Inflator Function
- Attach Air Hose: Screw the air hose onto the Aerated port of the GOOLOO A7 and then attach the other end securely to the tire valve.
- Turn On and Set Pressure: Press and hold the Power Switch for 2 seconds to turn on the device. The LED display will show the current tire pressure. Use the Pressure Increase (+) and Pressure Decrease (-) buttons to set your desired target pressure.
- Start Inflation: Press the Power Switch again to start inflation. The device will automatically stop when the target pressure is reached.
- Disconnect: Once inflation is complete, disconnect the air hose from the tire valve and the GOOLOO A7.
