The car charger uses a car cigarette lighter as a power outlet to directly charge the phone. Since the voltage provided by the car is low, only the overload protection circuit is needed inside the car charger. The front end of the car charger socket is designed with a fuse. When the current exceeds the overload protection circuit, the fuse is immediately blown and protects. Note: It must be charged when the car engine is started! Regarding the car charger, there are the following precautions:
1. Do not use the car charger in a humid environment.
