A 12V air compressor is an electronic device that compresses and pumps air. It is commonly used to inflate tires, but can also be used for other purposes such as inflating sports balls, camping gear, or even inflatable pool toys.
One of the main advantages of using a 12V air compressor is that it can be powered by a car battery, making it very convenient for on-the-go inflation. Additionally, most 12V air compressors are relatively small and portable, so they can easily be stored in a trunk or glove compartment.
When shopping for a 12V air compressor, it is important to consider the maximum PSI (pounds per square inch) rating as well as the CFM (cubic feet per minute) rating. The PSI rating will determine how much pressure the compressor can generate, while the CFM rating will dictate how quickly it can fill up a tire. For most passenger car tires, a 12V air compressor with a max PSI of 120 and CFM of 2 should suffice.
