Jump Starting a Vehicle
Before jump-starting, please take the following precautions:
- Read your vehicle owner's manual for specific steps and precautions.
- Turn off all electronics in your car (radio, lights, etc.) before jump-starting.
- Ensure you are in a dry, well-ventilated area. Never jump-start in an enclosed space.
- Remove any moisture from your JS-One unit, accessories, and vehicle's battery.
- Check that the vehicle's battery terminals are clean for best conductivity.
- Properly identify the vehicle battery's positive (+, red) and negative (-, black) terminals.
- Do not allow the metal teeth of the black clamp to touch the metal teeth of the red clamp.
- Do NOT connect the RED clamp to the vehicle battery's negative (-) terminal, or the BLACK clamp to the positive (+) terminal.
- When connecting smart clamps, ensure the copper teeth make good contact with the terminal.
How to Jump Start Your Car:
- Step 1: Connect Smart Clamps
Insert the plug of the battery clamps (12) completely into the EC5 Output Port (6) on the jump starter. The red and green LED Indicator (11) lights will flash alternately, indicating it's ready to work. - Step 2: Connect to Vehicle Battery
Connect the Red Battery Clamp (13) to the positive (+) terminal of the car battery and the Black Battery Clamp (14) to the negative (-) terminal. The green light on the LED Indicator (11) will turn solid, indicating a correct connection. - Step 3: Start the Vehicle
Start your vehicle. If the engine does not start on the first try, disconnect the clamps from the car battery and wait at least 20 seconds before reconnecting and trying again. - Step 4: Disconnect Clamps
Once the vehicle has started, remove the battery clamps from the car battery and then from the jump starter within 30 seconds.
4. Maintenance
- Recharge the Jump Starter every 3-4 months to maintain battery efficiency and prolong its service life.
- Check the power level of the product at least every three months and charge it if necessary.
- Always disconnect the jump start cables from your Jump Starter after use and store them separately.
- For protection, ensure the jump starter's battery capacity is above 75% before jump-starting your car.
5. Troubleshooting
The smart clamp features built-in protection that activates in certain situations, indicated by the LED Indicator (11):

9. Frequently Asked Questions (FAQ)
- Q: Is the jump starter suitable for my vehicle?
- A: Your car battery voltage should be 12V. The JS-One 2000A model is suitable for 12V petrol vehicles with displacement up to 8.0L and 12V diesel vehicles with displacement up to 6.5L.
- Q: Can the jump starter charge a car battery or be used for an electric car?
- A: No, it cannot charge a car battery. It is designed to provide a quick burst of power to jump-start a dead battery. It is not for electric cars.
- Q: What are the operating temperatures for the JS-One?
- A: The UTRAI JS-One can operate within the temperature range of -20ºC to 60ºC (-4ºF to 140ºF). It has thermal sensors to prevent operation outside this range for safety.
- Q: How often should my unit be recharged?
- A: We recommend recharging the UTRAI Jump Starter every 3 months and keeping it above 50% charge for emergency use.
- Q: Can the battery inside the JS-One be replaced?
- A: No, the internal battery is not user-replaceable. If the unit is faulty, it should be replaced.
- Q: Why is the red light always on and the alarm sounding?
- A: This indicates either a reverse polarity connection (red clamp to negative, black clamp to positive) or a short circuit (clamps touching each other or metal). Disconnect and reconnect correctly.
- Q: Why doesn't the jump starter work?
- A: The jump starter is designed to start a car with a dead battery. It will not work if the car battery or alternator is broken, or if the jump starter itself has low power.
- Q: What should I do if this unit can’t start a vehicle?
- A: Fully recharge the unit. Ensure correct connection to the vehicle battery; a solid green light should appear on the clamp. Attempt to start the vehicle within 30 seconds. If issues persist, contact customer support.
