UPDATE. Today I used it to bleed all tires to 36 after riding at the track. I had no problems with it! It worked very well and never stopped airing all 4 with no issues. I was worried it would overheat, it was 107 in the shade but it wasn't. good product. very satisfied. I bought it to inflate my jeep's tires after a trail. I tested it today before hitting the road next weekend. I drained the tire to 15psi. I plugged it in and it worked! I set it to 32psi and within 2-3 minutes it was inflated. The only thing I saw was that it lost 1psi when turned off. I reset it to 33 to make up for the loss. This time he lost 0.5 psi when he passed out. I'm very happy with what he's done so far!
