If it is connected for a long time, there may be a risk of power consumption, such as driving recorder or car refrigerator, which may be plugged in for one night and the battery will be dead the next day.
Therefore, after turning off the vehicle, it is necessary to cut off the power supply in time to avoid the battery losing power. In addition, for the service life of the battery, the official said that the electric energy conversion efficiency of the on-board inverter is as high as 85%, which can not only fill the power supply, but also will not damage the automobile battery.
Extended data
There are five kinds of models on sale in the market: cigarette lighter interface, fuse box, in-car USB interface, OBD interface and some common new SUV trunk 220V three hole socket. Almost all of them can see the cigarette lighter interface.
Therefore, getting electricity through cigarette lighters has become the choice of most car owners. However, for some vehicle-mounted electrical appliances that need to be used for a long time, such as driving recorder, if the cigarette lighter interface is occupied for a long time, the use of other vehicle-mounted electrical appliances will be affected. Therefore, taking electricity from the fuse box has become another common way to get electricity.
Because this is relatively safe and stable for the circuit of the whole vehicle, the interface also has certain universality. But it must be operated by professional technicians. If the owner can't judge which interface can supply power, it's best not to do it yourself.
