The car charger uses the car cigarette lighter as a power socket to directly charge the mobile phone. Since the voltage provided by the car is low, only an overload protection circuit is required 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 tolerable range, the fuse will be blown immediately to play a protective role. Note: It can be charged only 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
2. Do not store the car charger in a humid environment
3. The suitable temperature for use is 0-45℃
4. Keep away from children
5. Avoid lightning strikes
6. Pull out the plug in time after charging
