Choosing the right number of interfaces is the right way to use it. The more interfaces there are, the greater the amount of heat generated during use, which increases driving safety hazards. But it doesn't mean that the more interfaces, the more convenient. Choose the number of various interfaces according to the needs. Therefore, when choosing, select the type of interface according to the needs of existing electronic products. The cigarette lighter adapter output interface can be USB port, QC3.0 USB port, cigarette lighter socket, and even AC outlet. First of all, choose the output interface of the cigarette lighter adapter.How to choose a cigarette lighter adapter? In order to better protect the electronic device, each cigarette lighter socket of the adapter has an independent power switch, and some will add a main power switch. But the cigarette lighter device needs to be purchased separately.ĭue to the voltage value will suddenly increase when the car is starting, the impact resistance of electronic device should be good enough. If the cigarette lighter splitter is detected that the battery voltage is lower than 12V or higher than 15V, it is recommended to check the car battery in time or directly replace the battery.īecause the original cigarette lighter port of the car is occupied by the cigarette lighter adapter, some adapters will retain one of the sockets with a cigarette lighter function. Generally, before starting the car, the battery voltage is normal between 12.2~12.8V and the voltage range after starting is 13.4-14.8V. The digital display on the adapter can display the voltage value of the car battery in real time. Some adapters also add QC3.0 quick charging USB port, which can quickly charge mobile phones, tablets and laptops. The adapter usually has two kinds of output interfaces, one is cigarette lighter socket, which can provide real-time power to electronic devices such as GPS, MP3 converter, tire air compressor, car wash pump, and the other is USB port, which can charge mobile phones. The cigarette lighter adapter usually has the following functions: Therefore, it is particularly necessary to choose a multi-function and multi-output cigarette lighter adapter. However, most vehicles are only equipped with a cigarette lighter interface, it becomes very inconvenient to use multiple electronic devices at the same time. The most common ones are: GPS, dash cam, MP3 converter, power inverter, razor, tire inflator, car wash pump, etc. With the development of automobile technology, there are more and more in-vehicle electronic devices that use the cigarette lighter interface to obtain automobile power.
