Generally speaking, the cigarette lighter is composed of two parts, a power socket and a cigarette lighter. The socket part is responsible for supplying 12V DC power from the battery, while the cigarette lighter is mainly composed of electric wire and temperature sensor and other original components. In order to ensure the safety of electricity use, a cigarette lighter fuse is generally set separately in the insurance unit of the car to prevent the circuit from being overloaded. Of course, some high-end cars will also provide an additional set of 12V power output interface, but also need a special adapter plug to connect with the electrical equipment.
For cigarette lighter sockets, many people mostly stay on small things such as charging mobile phones when they are not smoking. In fact, this socket can be used for many purposes after being transferred by a dedicated car inverter, such as outdoor lighting, GPS, laptop computers, and tire inflation pumps can all work on the car's power supply. However, while enjoying convenience, you should also pay attention to the following points: 1. Read the power consumption of electrical appliances carefully. The circuit load of general household cars should not exceed 100W. Excessive power consumption can easily cause circuit overload and burnout. The fuse may even catch fire; 2. Try to use the on-board inverter when the car is running. If you use electrical appliances that consume large amounts of power when parking, you will quickly run out of battery power, and you will not be able to start the car when it is serious; If you install a cigarette lighter with a 2 socket, you can often see businesses selling cigarette lighter with a 2 socket in the auto parts city. Generally speaking, when the car is shipped from the factory, the circuit has been designed with the most reasonable design. The output device jack can easily cause circuit instability, so you need to be extra cautious when purchasing such products.
