note:The correct method of car charging is also needed. Many people like to insert the car charger into the cigarette hole of the car before the car is ignited. At this time, once the car is ignited, a momentary high voltage will be generated, which will burn out the car charger to a large extent. So, if you have this habit, you must correct it, and habitually pull out the car charger from the car cigarette hole after the car is turned off. This is a good usage habit and also prevents the car charger from being used. An important protection against sudden burnout.
