User Manual for Buture BR800 Car Jump Starter

Quick guide from the manual

The Buture BR800 is a 12V car jump starter. Before using it to start your vehicle, ensure the device is charged to at least 50% (3 or 4 indicator lights illuminated). This device is intended for 12V vehicles only. Always ensure the blue plug is securely fitted into the jump start socket before attempting to start the car.

Product overview

The jump starter features the following components:

• ON/OFF Button: Used to check battery capacity and turn on the device.
• Battery Indicator: Shows current charge level (25%, 50%, 75%, 100%).
• 5V/2.4A USB Output: Used for charging mobile devices like phones or tablets.
• Flashlight: Built-in light.
• USB C Input: Used to recharge the jump starter.
• Jump Starting Port: Connection point for the smart jumper cables.

Recharging the jump starter

The unit does not come with a wall charger. You can use a universal USB charger (5V/2A suggested). To recharge:

1. Plug the USB cable into a USB wall adapter or car adapter.
2. Connect the USB-C cable to the unit.
3. It is recommended to recharge the unit every 3-4 months to maintain battery health.

Charging your devices

You can use the jump starter as a power bank:

1. Connect your device's original USB cable to one of the USB output ports.
2. Press the power button once to begin charging.
3. The power level indicator will display the remaining battery capacity.

Jump starting your car

1. Put the vehicle in Park (or Neutral for manual transmission) and engage the emergency brake.
2. Insert the smart battery clamp plug completely into the jump starter.
3. Check the clamp indicators: if green and red lights flash alternately, proceed.
4. Connect the red clamp to the positive (+) terminal and the black clamp to the negative (-) terminal of the car battery.
5. If the clamp indicator is solid green, start your car.
6. If the car fails to start, disconnect the clamps, wait 30 seconds, and try again.
7. Once the car is started, remove the clamps from the battery and the jump starter within 30 seconds.

Smart clamp protection

The smart clamp includes safety features. If the red light is always on, check for reverse connection or short circuits. If the red light flashes slowly, the car battery voltage is too high (>12.6V), meaning no jump starter is needed. If the red light flashes quickly, the clamp temperature is too high (exceeds 65°C); remove the clamp and let it cool.

Safety and maintenance

• Do not operate in explosive atmospheres (flammable liquid, gas, or dust).
• Do not modify or disassemble the product.
• If battery leakage occurs, take it to a local battery recycling center.
• Keep the product away from water.
