When charging, the bottom end of the car charger can be inserted directly into the bottom of the cigarette lighter. It should be noted that since there are two spring pieces in the cigarette lighter to fix the cigarette butt, it cannot be inserted against the spring when the car charger is inserted into the cigarette lighter, which will damage the cigarette lighter and the car charger. When you use it, just insert it from the track next to the spring piece.
