1. Light a cigarette

Insert the cigarette lighter into the car power socket and press down to fix it. When the heating wire of the cigarette lighter reaches the temperature, it will automatically pop out. At this time, the heating wire turns red, and we can light the cigarette. put the unit back into the power outlet position.

2. Vehicle power supply

It should be the habit of most car owners to use the cigarette lighter jack as a car power supply, but we should avoid using electrical appliances with a power exceeding 120W in the car. Because the maximum current that the cigarette lighter circuit can withstand is generally 10A (also 20A). Calculated according to the 12V voltage of the cigarette lighter jack, if the total power of the vehicle electrical appliances exceeds 120W, the cigarette lighter circuit will be overloaded.

It should also be noted that we should not continue to draw power from the cigarette lighter socket when the vehicle is turned off, otherwise the battery will be easily exhausted and the car cannot be started again. If the power of the on-board electrical appliances is too large and the circuit is overloaded, the possibility of the battery being scrapped will be greatly increased.

3. Mistakes

After using the external device, it will remain on the cigarette lighter without unplugging it before turning off the flame, which will undoubtedly cause trouble. When the vehicle is started, the external devices on the cigarette lighter are easily burnt under the impact of starting a large current, especially MP3 and U disk are prone to problems. Therefore, unplug it after use, and then plug it in after the car is started.

During use, the plug and reed of the external device are deformed due to the shaking of plugging and unplugging, which causes the plug to be loose after insertion, and the contact is not strict, which affects the conduction. The phenomenon is that it is on and off. If this phenomenon is found, it can be solved by adjusting the angle of the arc reed of the plug.
