What is the use of the trunk cigarette lighter?

[SanJude]

The trunk cigarette lighter can be used for smoking and saving fuel. The following is a related introduction about the car cigarette lighter: 1. Differences: The power supply of small cars is generally DC 12V (may vary depending on the model), with the central elastic head as the positive pole and the two side buckles (ears) as the negative pole. It is directly connected to the car battery, with the same current and power as the battery. 2. Uses: The car cigarette lighter is an electronic device similar to a multi-hole power socket for household use. It connects to the car power supply through a plug and then extends multiple cigarette lighter sockets. The cigarette lighter socket is very useful for car owners who frequently use car electronic products, such as charging mobile phones, MP3/MP4, and other digital products. In addition to being used for smoking, the car cigarette lighter can also be equipped with a car inverter, which can convert the car's 12V, 24V, or 48V DC power into 220V/50Hz AC power for ordinary electrical appliances. It is best to use a split-type car inverter, with the power of the electrical appliance limited to below 150W, and the output current should not exceed the battery current.
