Special Precautions for Using a Portable Power Bank

1. When starting the car, make sure to insert the blue plug firmly and fully, or it may affect the effect.

2. When starting the car, it is best to have a blue battery indicator above 60%, which can extend the product's service life.

3. If the car cannot be started, do not forcefully continue to start it. Check if the battery clips are securely fastened, and if the original car battery terminal is rusty or has dirt. Clean it up and then try to start the car again.

4. During the startup process, if the vehicle cannot be started at all (1-2 times), do not forcefully continue to start it. Further checks should be made to determine if there are any other faults. Otherwise, it may lead to the burning of the fuse and damage to the starting power supply.

5: When starting the car and using the air pump and other vehicle-mounted appliances through the clip port, you need to turn the switch to the OFF position.

6: Our store offers different styles of car power supplies in 400A and 600A. If your car exceeds the A number of our products, the power supply will automatically cut off power during the start-up process to protect the car. Simply plug in the charger to reactivate and it will work normally.

If the car is powered on, remove the positive terminal, clamp the clamp to the ground, and connect the negative terminal to the negative terminal. The car can be started.
