3. Specifications

Note: While the product description mentions 'Battery Capacity' and 'Number of Built-in Batteries', the Jstar X1 primarily uses super capacitor technology for energy storage, which is distinct from traditional chemical batteries. The '5 built-in batteries' likely refers to the individual supercapacitor cells within the unit.

4. Safety Information

Please read and understand all safety information before using this product. Failure to follow these instructions may result in electric shock, explosion, fire, which may result in serious injury, death, or property damage.

• Battery-Free & Super Safe: The Jstar X1 uses super capacitor technology, which is inherently safer than traditional lithium-ion batteries. It is designed to be explosion-proof and fire-resistant.
• Correct Polarity: Always connect the red clamp to the positive (+) terminal and the black clamp to the negative (-) terminal of the vehicle battery. Incorrect connections can cause damage to the device, vehicle, or personal injury.
• Ventilation: Ensure the area is well-ventilated during use.
• Avoid Contact: Do not allow the red and black clamps to touch each other or any other metal object.
• Keep Dry: The device is dustproof and waterproof, but avoid submerging it in water.
• Children and Pets: Keep the device out of reach of children and pets.
• Storage: Store in a cool, dry place away from direct sunlight and heat sources.

Jstar X1 features: Green Energy, No Pollution, Dustproof & Waterproof, Shock-proof Structure, No Catch Fire or Explode.

5. Setup

The UTRAI Jstar X1 does not require pre-charging for emergency jump-starting as it can draw power from the vehicle's battery. However, for optimal performance and to ensure it's ready for any situation, it's recommended to keep it charged or charge it periodically.

Initial Charging (Optional but Recommended)

While the Jstar X1 can charge from a dead car battery, you can also charge it fully using an external power source:

• Via DC Input: Connect the jump starter to a DC power source using the appropriate cable.
• Via Type-C Input: Connect the jump starter to a compatible Type-C charger using the provided USB cable.

A full charge from an external source typically takes about 5 hours. The display will show the charging progress.

6. Operating Instructions: Jump Starting Your Vehicle

Follow these steps to safely jump start your vehicle:

1. Prepare the Vehicle: Ensure your vehicle is in Park (P) or Neutral (N) and the parking brake is engaged. Turn off all vehicle accessories (lights, radio, A/C, etc.). Open the vehicle's hood.
2. Connect Clamps to Jump Starter: Insert the smart clamp connector firmly into the jump starter's port.
3. Connect to Car Battery:
   • Attach the RED (+) clamp to the positive terminal of your car battery.
   • Attach the BLACK (-) clamp to the negative terminal of your car battery.
   Ensure the connections are secure and there is no corrosion on the battery terminals.
4. Charge the Jump Starter: The Jstar X1 will begin to draw power from your car's weak battery to charge its super capacitors. The display on the jump starter will show the charging progress. It will be fully charged within approximately 3 minutes. When the display shows "100%" and the voltage, it's ready.
5. Initiate Start: Press the power button on the jump starter. The device will emit regular ticking sounds for about 10 seconds.
6. Start Engine: After the regular ticking turns into a long beep, start your vehicle's engine within 30 seconds.
7. Remove Clamps: Once the engine starts, immediately remove the smart clamps from the car battery, first the black (-) clamp, then the red (+) clamp, and then disconnect from the jump starter.

Important Note: For the 3-minute quick charge from your car battery, the car battery's left voltage must be above 5V.

7. Charging the Jstar X1

The Jstar X1 offers multiple ways to charge its super capacitors:

• From a Vehicle Battery: As detailed in the operating instructions, connect the clamps to a vehicle battery (even a weak one, provided it's above 5V) to fully charge the Jstar X1 in approximately 3 minutes.
• Via DC Input: Use a compatible DC charger and cable to charge the unit.
• Via Type-C Input: Connect the Jstar X1 to a Type-C power adapter using the provided USB cable.

Note: The Super Capacitor will automatically release all the power stored after 24 hours of charging. This is a normal characteristic of super capacitors and ensures the device is always ready to quickly charge from a vehicle battery when needed, without needing to maintain a full charge for extended periods.

8. Maintenance

• Cleaning: Wipe the unit with a dry, soft cloth. Do not use harsh chemicals or abrasive materials.
• Storage: Store the Jstar X1 in its carrying case in a cool, dry place. Avoid extreme temperatures and direct sunlight.
• Durability: The Jstar X1 is designed to be dustproof, waterproof, and shock-proof, ensuring durability in various conditions.
• Lifespan: With a lifespan of approximately 10 years and 100,000 uses, the Jstar X1 requires minimal long-term maintenance compared to traditional battery jump starters.

Jstar X1 is always ready for extreme weather conditions.

9. Troubleshooting

Device not charging from car battery:

Ensure the car battery's voltage is above 5V. Check for secure connections of the clamps to both the jump starter and the car battery terminals. Clean any corrosion from battery terminals.

Vehicle not starting after jump start attempt:

Verify that the clamps are connected correctly (red to positive, black to negative). Ensure the jump starter was fully charged (100% displayed) before attempting to start. Wait 1-2 minutes and try again. If the vehicle still doesn't start, there might be a more significant issue with the vehicle's battery or starting system.

No display or unresponsive unit:

Ensure the unit is connected to a power source (car battery or external charger) to activate. If using an external charger, ensure the charger and cable are functional.

10. User Tips

• Minimum Battery Voltage: Remember that for the Jstar X1 to quickly charge from your car's battery, the car battery's voltage must be at least 5V. If your battery is completely dead (below 5V), you will need to charge the Jstar X1 using an external DC or Type-C power source first.
• Engine Compatibility: The Jstar X1 is suitable for a wide range of vehicles, including those with up to 8.0L gas engines and 7.5L diesel engines. This includes many common diesel vehicles, such as 3.0L diesel engines.
• Always Ready: Due to its super capacitor technology, the Jstar X1 does not require constant monitoring of its charge level. It's designed to be 'Always Ready' by quickly charging from your vehicle's battery when needed.
