Check out Project Farm youtube channel. He tested a lot of different battery compressors from super cheap to expensive. Includes Dewalt and Milwaukee.  He's very good.  Looked out how long it takes to pump different size tires and an air mattress.  How accurate the gauges were and how close they shut off to target.  How hot they got and how loud they were.
