With the popularity of smart devices such as mobile phones and tablets, car chargers have become an indispensable digital peripheral for car owners, and there are many types of car chargers, with two ports and three ports, with fast charging, with extension, etc., so how should these car chargers be used?
First, start the car engine
Why is such a simple operation listed in a separate step? It is because the current is large when the engine starts, which may burn out the charging equipment and even threaten personal safety.
Second, open the car cigarette port and plug in the car charger
The operation here is simple, it should be explained that the indicator light lights up after the car charge is inserted, and you can move back and forth a few times to ensure that the car charge shrapnel is firmly stuck.
Three. Plug in the charging device for charging
USB devices such as mobile phones and tablets that are usually used here can be charged, and do not connect to devices with excessive power.
Finally, I would like to emphasize:
Be sure to start the car engine before you can connect to the charging device to charge!
Another point is that the voltage and current in the on-board environment are unstable, try to choose a brand car charger with over-current protection and short-circuit protection, after all, once an accident occurs, the damage to the car charger is small, and it is not cost-effective to damage the mobile phone.
