The car charger uses the car cigarette lighter as a power outlet 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 tube. When the current exceeds the acceptable range of the overload protection circuit, the fuse will be blown immediately to play a protective role. Note: It can only be charged when the car engine is started! Here are some more notes about car chargers:
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
Therefore, for safety reasons, you must buy regular brands and buy genuine products. Poor quality products are prone to safety hazards. There are two types of car chargers: direct charging and cradle charging. You can choose to buy a cradle charger, that is, remove the battery to charge, to avoid the phenomenon of burning the phone due to unstable vehicle power supply and high voltage output peak. There are a variety of car chargers available on the market. If you choose to buy online, you must go to the official website to buy. The better websites include Jingdong Mall, Dangdang.com and Qiqi.com. The first two are large-scale comprehensive malls, while Qiqi.com is currently the largest and most professional online car accessories store. .
