Vehicle charger uses car cigarette lighter as power outlet to charge mobile phone directly. Because the voltage provided by the car is low, only the overload protection circuit is needed inside the vehicle charger. The front end of the vehicle charger socket is designed with a fuse. When the current exceeds the acceptable range of the overload protection circuit, the fuse immediately fuses and plays a protective role. Note: The car must be charged when the engine starts! Regarding on-board chargers, the following points should be noted:
1. Do not use on-board chargers in humid environments
2. Do not store on-board chargers in humid environments
3. The suitable temperature for use is 0-45 C.
4. Keep away from children
5. Avoiding Lightning Stroke
6. Pull out the plug in time after charging. For safety reasons, we must choose the regular brand and purchase the genuine products. The poor quality products are very vulnerable to security risks. Vehicle chargers are also divided into direct charging and seat charging. You can choose to buy a seat charge, that is, to take the battery off and charge, to avoid the phenomenon that the mobile phone burns because of the instability of the vehicle power supply and the sudden peak voltage output. To burn the battery is also to reduce the loss. At present, there are a variety of on-board chargers available on the market.
