This is the world's smallest fast-charging car charger. It is small enough to be completely put into the car charging socket, and the socket cover can be completely covered to achieve an invisible state without destroying the beauty of the car interior design. At present, the top of the fast-charging car chargers already on the market is exposed to the outside when they are used, which is very unstable. If the user accidentally pulls the data cable, it is easy to cause poor contact, causing the driver to check the situation and resulting in unsafe factors. A car charger with a small enough volume cannot achieve fast charging, or it is inconvenient for users to plug and unplug during use. This mini car charger is made with new technology, which can charge multiple electronic devices safely and quickly at the same time. A rotating handle is also designed on the top, which can easily lift the car, making it more convenient for users to use.
