Car Power Supply Converter Transformer Convert 24V To 12V Cigarette Lighter Type DC-DC Converter 20A Feature: There are many uses for automotive 12V power supplies, such as charging mobile phones, driving recorders, small refrigerators, decorative lights, etc. In addition, if the vehicle fails at night when driving, and there is no lighting, do not worry, the car's power can be connected to the lighting, which is convenient to use. What does it mean to use improperly? The main reason is that the power of our car electrical appliances exceeds the maximum power of our battery. The current of the fuse of our cigarette lighter is generally about 10A. The voltage of 12V multiplied by 10A is 120W. This is the maximum power of most of our cars. Electrical appliances over 120W will blow the fuse. Enter the end point cigarette lighter car charger design, plug directly into the cigarette lighter hole to work. The power indicator display is intuitive, when it is on, it is working, otherwise it is not working. Lengthen and thicken the connection cable to facilitate the supply of high-power automotive appliances.
