How to use and choose a car charger
With the continuous development of the economy, owning your own car is no longer difficult, but after buying a car, you will face a series of problems. Nowadays, with the development of intelligence, the connection between cars and mobile phones is becoming increasingly close, and some cars can even support direct control of mobile phones. Many car owners are accustomed to using car chargers in their cars, but you may not expect that this car charger also poses significant safety risks.
First of all, we need to popularize the working principle of a car charger, which converts the 12V voltage of the car cigarette lighter socket into a 5V USB voltage and charges electronic products through a charging cable. This way, the power consumption is small, the operation is simple and convenient, and the key is that the price is also cheap.
So what precautions should be taken in daily use of car chargers?
First of all, do not insert it before starting the vehicle to prevent the voltage during vehicle startup from damaging the on-board charger; Secondly, never use chemicals, cleaning agents, etc. to clean the car charger, which is very dangerous; During use, be careful not to enter water or be exposed to humid air when not in use for a long time; Finally, the on-board charger should be unplugged after the vehicle has stalled.
So how should I choose a car charger?
First of all, it is very important to pay attention to whether the car charger has an overload protection function when selling it. Because once overload is not protected, the life of the charger will decrease, and the risk of danger will greatly increase. Secondly, when selecting an on-board charger, try to choose a product with an output current of more than 1A, otherwise charging may not keep up with consumption during use, resulting in less and less charging.
