Went to an offroad park, and after a day of trails over rocks and mud, hooked the compressor up to my Bronco's battery and aired-up for the drive home. It was great - only a few minutes to get a 35"" MT tire back up to highway pressure. I originally wanted a compressor that installed on-board, but I can see circumstances where it might be a bit of wait to be able to get my rig parked next to a friend's. Though a bit heavy, I can just carry this compressor over to my friend's rig without worrying about moving vehicles.Pluses - inflation speed. Included air hose easily reaches all tires, including the spare (2-door '23 Bronco)Minuses - It is a bit heavy, but it's worth it for the airflow. Small minus, the carry case isn't big enough to hold the inline air-pressure gauge I bought separately.
