The principle of car charger

Using the socket of the car cigarette lighter as the power source, the power of the cigarette lighter comes from the battery of the car, and the voltage is DC12V. The so-called car charger is a 12V voltage input charger, if the phone is charged, the general output voltage is 5V.

The car charger works like a voltage regulator, but there are some additional features, such as automatic power-down after charging. 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.

Through the above discussion, I believe that everyone has an understanding of the principle of car charger. When we purchase the charger, for safety reasons, we must purchase a regular brand, buy genuine, inferior products are prone to security risks, if you choose online shopping, you must go to the regular website to buy.
