Review on VIAIR 30033 300P Portable Compressor by Darrell Shreves

I use it in my Jeep when I'm going off road and need to take my tires down to 10-15 lbs. With the old pump, it would take 20-25 minutes for the tire to gain weight back to 35-40 pounds. With this compressor it takes MAYBE 10 minutes and maybe closer to 5-7 minutes. That thing is a beast. I've also used it to lift tires on my RV. So we're talking over 90 pounds of tire pressure. If I had to guess, I'd say it lasts about as long at lower pressure, which is really impressive. You usually see a sharp drop in speed when you reach these higher pressures.
