Tire inflation air compressor

I am considering a portable tire inflation compressor. The Interdynamics 120v power air looks like it will do the job and is priced right, about $40. I'd like to have something available on board since gas station air is not always easy to reach with the RV. At the same time needing air is a "once in a while" event and not something I want to spend a lot on.

Has anyone used one? Opinions?

One specific possible problem that I noticed is that the inflation chuck is permanently fixed on the air hose. You can not replace it with a dual-footed chuck to reach the outer dually tire. That being said, the chuck provided does have a lever to lock it on the valve and it LOOKS like it might manage to be attached to the outer wheel. The package in the store is sealed and so I can't take it out to try it first. I'm hoping someone else may have already tried.

You can probably cut the factory fitting off the hose and add your preferred end to the hose (like the dual footed type). You could even change the end for a quick connect chuck type then use any type of fitting you choose.

A small compressor like that won't deliver much volume of air at higher pressures. If you need more than a pound or two at something like 80-100 psi, you could spend quite a while waiting for it to pump it up.

It's simple to deliver high output pressures but not to produce a large air flow (CFM). That takes more hardware and that's where the low priced compressors fall down.

Having had a portable compressor lock up and strip the geartrain while topping up the spare on the side of Interstate 45 after a blowout, my only advice would be:

If you're going to rely on it to get you out of a jam, don't cheap out! I now carry a Campbell Hausfeld pancake (tankless) compressor.

There is a nice compact DeWalt compressor @ HD that has a tank pressure of 200psi, and a Rigid that goes 175psi. These two are good choices for tire pressures; each has regulator to dial down the output pressure.
Also, you can permanently mount either by dividing the tanks & regulator & compressor into parts, & replumbing as needed for your space. I'm thinking of installing the DeWalt compressor plus regulator/gauge package but going to a remote aluminum tank for weight and putting the gauges/switch control where they are handy. The space behind my steering box is just wasted otherwise; why not carry a real compressor there with an air chuck plumbed to the front & one to the rear patio side?

I've tried a number of small compressors and found them all wanting. I just purchased a 12 volt, high volume, 150 psi compressor from Harbor Freight and used it yesterday to top off all my tires. I like it so far. Take a look.http://www.harborfreightusa.com/usa/...bCategoryName=

Check out the Air Lift air compressor. It's pricy, but works VERY well. It comes will all the fittings, extra hose, gauges and is a very small unit that is easy on storage space.

Check out VIAIR compressor. they are pricy but they will do the job. Check out Amazon and read the comments. I have used those cheap models over the years and they take forever to add 2 or 3 pound to an RV tire, plus they won't last.

On the Harbor Freight compressor that I purchased, I also bought their 2 year replacement plan for ten bucks because I've also burned out a number of the cheap ones. In the store where I bought it, the clerk said even if I think it might not be running correctly before the two year point, bring it back and get a new one.

I agree with Bruce H; I too have bought a less expensive tank type compressor and it is now it's in my garage. Spend your hard earned bucks on a tankless compressor that will go at least 150 psi. Good luck!

I just took a look at the viair 150 psi model. It looks and has similar specs to the Harbor Freight model I posted a link to. With the 2 year replacement plan it looks like it MIGHT save you $100.
