1、 Electric overload

Generally speaking，The power supply voltage of the cigarette lighter jack is 12V，The maximum current that the cigarette lighter circuit is generally 10A (also 20A)。The maximum total power of the vehicle electrical appliances that can be affected by a cigarette lighter is 120W。If the total power of the vehicle electrical appliance exceeds 120W，Then the cigarette lighter circuit will be overload。So，We should avoid using electrical appliances with power exceeding 120W in the car。

2、 Be careful to use porous diverting cigarettes sockets

A porous diversion cigarette lighter socket appears on the market，The design of its "one drag and three" or even "one drag n"，It is greatly convenient for the owners who have many vehicle equipment。but but，This seemingly practical expansion equipment，In fact, it is more likely to have overload problems，Pay more attention to whether the total power of the electrical appliances exceeds the circuit load when using it。

3、 Parking stall continuously

In addition seabet loginto some high -end cars, there is the function of automatic power off，Most models do not have this function。Note，After stopping the parking here，The cigarette lighter continues to work，This will affect the service life of your vehicle equipment and the battery of your car，Second, it is easy to exhaust the battery of the battery，As a result, the cars cannot be started again; in addition, the most serious results，It is spontaneous due to the long -term work with electrical appliances。
