I have a few air sources in my garage but the latest addition to my daily driver was one of these I got on sale to keep in the trunk and it does everything. After reading reviews of people even comping with it I had to give it a try. So far very pleased only charged it once when I first got it like 2 months ago and still holding a charge and I've used it several times to top off air.
