Operating Instructions
Jump Starting a Vehicle
Follow these steps to safely jump start your vehicle:
- Prepare the Vehicle: Ensure the vehicle is in PARK (automatic) or NEUTRAL (manual) and the parking brake is engaged. Turn off all accessories (headlights, radio, AC, etc.).
- Connect Jumper Cables:
- Connect the red (positive, +) clamp to the positive terminal of the vehicle's battery.
- Connect the black (negative, -) clamp to the negative terminal of the vehicle's battery.
- Ensure the battery terminals are free of corrosion.
- Connect to Jump Starter: Plug the jumper cable connector into the jump starter's insulated port.
- Check Display: The LED display should show "READY" solid. If it blinks, the battery voltage is very low, and you may need to press the "BOOST" button (refer to troubleshooting).
- Start Vehicle: Once "READY" is solid, start your vehicle's engine.
- Disconnect: After the vehicle starts, immediately disconnect the jumper cables from the jump starter, then from the vehicle battery (negative first, then positive).
Kindly Reminders:
- ● Ensure the battery terminals are free of corrosion.
- ● Ensure the battery power is higher than 20% before jump starting the vehicle.
- ● Ensure the vehicle is in PARK gear and all accessories (headlights, audio, etc.) are turned off.
- ● Ensure two clamps are connected to proper terminals.
- ● DO NOT press the BOOST button before connecting the vehicle battery correctly.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| "READY" light is blinking on the display. | The car battery voltage is extremely low (below 1V). | Press and hold the "BOOST" button for 3 seconds until the "READY" light becomes solid. This activates the override mode. Attempt to start the vehicle within 30 seconds. |
| Jump starter does not turn on or charge. | Battery is completely depleted or charging cable/adapter is faulty. | Ensure the jump starter has at least 20% charge. Try a different charging cable or adapter. If the issue persists, contact customer support. |
| Vehicle does not start after jump attempt. | Incorrect cable connection, severely damaged battery, or other vehicle issues. | Double-check that the clamps are securely connected to the correct battery terminals (positive to positive, negative to negative). Ensure battery terminals are clean. If the battery is severely damaged, it may not accept a jump start. Consult a mechanic for further diagnosis. |
| Charging indicator seems inaccurate. | Temporary display glitch. | Stop the charge, wait 10 seconds, and reconnect the USB charger to reset the charging indication. |
