Hello, the car charger with the Yuan plus generally needs to use the 12V DC socket of the car, also known as the car socket or cigarette lighter socket. This socket is usually located in the center console or dashboard of the car and is used to connect the on-board electronics and chargers. When inserted into the car charger, it will convert the direct current of the car power supply into the electric energy required by the car charger to charge or supply power to other devices.
