Hi, I'm in the market for a reliable, portable air compressor for inflating tires; specifically LT (light truck) tires on my pick-up. It seems like all of the small ones I've seen are cheap junk, and only work on passenger tires inflated around 35psi or less. I need something that would reliably inflate LT tires to 60psi, without buying some really expensive unit that would just be overkill. I also need it to be portable, with a 120V cord and plug to power it at home in the garage and a 12V option to plug it into the cigarette lighter in my truck to inflate a low tire in the field. Can anyone recommend such a model that has worked well for them? Any advice/recommendations would be appreciated.
