Viair portable air compressor does the job!


Andy Pargh, the Gadget Guru, demonstrates the Viair 400P portable air compressor. The small compressor will fool you as it’s a fraction of the size of a typical air compressor but has enough power to inflate a full-size motorhome tire. editor Chuck Woodbury travels with a similar model and loves it. In this 14-minute video, Andy thoroughly explains the unit and shows it in action. If you are interested in purchasing the compressor, it’s listed along with similar models at

When you remove the red plug, there is a round filter you should screw in to help ensure trash doesn’t get into the workings of the compressor.

I’ve used a Viair compressor for eight years now. I keep it in my truck and it has never failed me. The model I have is rated for continuous use and never overheats. Makes it very easy to pump up my tires whenever I need it. I really recommend this pump…


Sounds interesting, I was wondering how you can put in 115 PSI, when the the VIAIR has a 110 PSI cut off switch. I’ve used just about every type of portable air compressors in my 50 years of off roading. My first was an Engine Air Compressor, you . had to take a spark plug out & screw in a valve & turn on your engine & the slower it ran the faster it filled your tire, actually it was great except for the 500 degree fitting when you went to unscrew it from the engine. I have a York compressor from an air conditioner unit adopted to my 2006 Jeep, works awesome especially at 10 CFM. I like using my Diesel compressor as it has a 18.5 CFM output, really awesome
Thanks for listening

Does it come with a warranty?


It’s a lot easier to make the connections if the hoses aren’t pressurized. So first connect everything and then turn on the compressor.
