VIAIR 30033 300P Portable Compressor Review

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…

I used it for the first time today and am so happy with it! The stock tires on my 2018 Tacoma are pretty much the size that this supercharger is designed for and are easy to inflate after I hit the beach. Going from 20psi to 30psi was a matter of about 30 seconds per tire, which helped me cut my run times in 90-degree heat. I foresee a long useful life. I will echo what others have said regarding the length of the power cord, wishing it was a little longer, but the black coiled hose that comes…

The compressor works well but has a design flaw. The pressure gauge is located next to the tire and the switch is located on the back of the compressor. I called support to see if they had a fix for this small issue. Her answer was $100 more. They didn't seem to realize there was a problem. I copied the design from another Revain reviewer. I used electroplated fittings to place the pressure gauge in the correct location on the back of the compressor. That way I can turn it off when it reaches…

bought a few years ago. Pumps very well but has some serious limitations. First, the short power cord combined with the rolled-up air hose makes inflating the rear tires unnecessarily difficult. Especially on my F150 truck. To get to the rear wheels you actually have to straighten the spiral hose, which causes the compressor to tip over and you have to walk between the gauge and the pump switch. Over the years, the fork no longer "jams" on the tire, so it has to be pressed against the tire…

I've had this compressor for over a year now. I bought it mainly for emergencies but I use it to maintain proper tire pressure. I don't really like the twisted hose that comes with it because I have to stretch it quite a bit to get to the rear wheels and it doesn't reach the trailer wheels. What I also don't like is that the pressure gauge is on the tire - so you have to switch between tire and compressor (switch off compressor, check tire pressure, switch on compressor, etc.). I have a 50'…

I wanted a portable, reliable, quality, fast and powerful tire inflator. This product has all of these qualities to the fullest! That's probably a lot more compressor than I need for my three passenger cars: a small commuter, a minivan, and a large van. This seemingly robust product comes with a quality carrying/storage case. Inflates quickly! Do not move away from this product while using it (there is no automatic shut-off, and again with normal sized car tires this quickly builds up…
