Car 220V power supply can be used to power some small appliances, but cannot support high-power electrical equipment. The following is a related introduction about car power supply: 1. Function: Car power supply, also known as a power inverter, is a device that can convert DC12V direct current into AC220V alternating current, which is the same as household electricity, for use by general electrical appliances. It is a convenient power converter. 2. Automatic protection: Car power supply fully considers the external usage environment and will automatically shut down for protection when overload or short circuit occurs. The output voltage of the car power supply can be stabilized through its own feedback confirmation, with the voltage change between no-load and rated voltage being less than 10V.

I have a 220V power outlet installed in my car, which is extremely practical! During daily commutes or long-distance trips, I often use it to charge my laptop, ensuring uninterrupted office work. Occasionally on weekend outings, I can plug in a mini coffee maker for a refreshing brew, and the car fridge keeps food fresh. However, it's important to note the power limitations. Generally, a car's 220V socket can handle devices with a maximum power of 150-300 watts. Avoid plugging in high-power appliances like hair dryers, as they may trip the circuit and damage the battery. I once nearly burned out the socket with a high-power electric kettle, so now I make it a habit to check the manual to know which appliances are supported. Overall, it makes life in the car more convenient and saves the hassle of finding charging points.
