With the popularization of smart devices such as mobile phones, car chargers have become an indispensable digital accessory for car owners. There are many kinds of car chargers, including two ports, three ports, fast charging and expansion. So how should these car charges be used?

1. Start up automobile engine

Why is it that such a simple operation lists a single step? Because the current of the engine is high when it starts, it may burn the charging equipment and even threaten personal safety.

2. Open the cigarette-lighting port of the car and plug in the on-board charger

The operation here is simple. It should be noted that the indicator lights up after the car fills and inserts, and can move back and forth several times to ensure that the car filling fragments are stuck firmly.

3. Insert charging equipment to charge

USB devices such as cell phone tablets can be charged here, so don't connect to devices with excessive power.

Finally, we should emphasize that:

The charging equipment can only be charged after the automobile engine is started.

Another point is that the voltage and current are unstable in the vehicle environment. We should choose the brand car charges with over-current protection and short-circuit protection as far as possible. After all, once an accident occurs, the damaged car charges are small, and it is not worthwhile to damage the mobile phone.
