I want to carry portable air compressor for emergency, any suggestions? 12 volt or electric? I do have honda 3000 generator in my truck if electric is way to go. appreciate some advise. Thanks

We have the Ryobi air compressor and the Ryobi 18v drill to adjust the jacks and stabilizers. We love it

We picked up a fairly beefy unit for little $ at a WalMart on the road. It claims to be for 'Big' tires and had no trouble getting the tires up to 60 Lbs. on a mountain, and included a nice case and some plugs and tire "Goo". It was the most expensive one at Walley World but that is still cheaper than the cheapest at Camping World. If this will not do the job I call 'AAA RV'!

BTW, it is a 12 v. unit and it is small enough to slide under the seat in the TV but not too small that you forget were it is.

I think this compressor is awesome. I can use it to fill tires, winterize the RV by blowing the water lines, and I have an attachment to blow air if I need to dry something. Bought it on Amazon.

I've used one of these for several years...It comes in a hard plastic case...

12 Volt, 150 PSI High Volume Air Compressor

I installed a Male 12 volt type plug on the end, replacing the clamps, I then installed a female 12 volt plug on the wires from the clamps as a 'adapter' in needed...

I have the same one but came with a cloth case. It's a big big improvement over the old Coleman's.

I have one very similar to Ahab's. Check in with the off-road jeep forums for a lot of discussion on the 12 volt units. They use and modify them heavily.

This is what I bought: VIAIR 450P Automatic Function Portable Compressor : Amazon.com : Automotive

After my research, this is what I determined to be the best that I could buy. I wanted one that would never fail and had no duty cycle, that is, could run continuously.

The HF unit is obviously a good price but the manual says nothing about duty cycle. My experience with HF stuff is that it is cheap and will work, but is not well made for the long term.

Anyone have experience with Viair units enough to know how well this one would work? Thinking of something for LT tires. 80-90 psi.

Bought one of those in late 2012 to use both with the trailer tires and the TV tires (275/55 R20). It does an excellent job, doesn't take too much time to fill the larger tires and seems to be very well built. I don't hesitate to recommend it to people who want a good 12-volt pump that does not take forever to fill the tires.

Ditto on the Viair 88P. I use it on both the trailer and TV. My nephew bought one at the same time to use on his offroader to air up his 33 in. tires and is also happy with it.

I just installed a Viair 400c, real happy with it.

SCOTTinNJ · 03-19-2015, 01:41 PM

Thanks all.

After buying several crappy compressors, I went with a Viair 90P which cost about $70.00 on Amazon. It more than meets my needs for the Silverado and FC. The only drawback is that is requires direct clipping to battery terminals and reach can be an issue. I carry either a small 12v battery or use my jumper cables.

Msmoto · 03-19-2015, 02:10 PM

Gosh, I just realized with the AS I have no source of compressed air as I had on the moho....mmmmm....will need to fix that I guess....correct?

Bluestar99 · 03-19-2015, 02:20 PM

This one is very popular with the offroad guys. I carry one to air up my tires after a day on the trails. It out preforms the Viair. Even the Big expensive model. More then once I have been parked next to a guy with the big Viair and I finished airing up before he did. If you don't want to break the bank. you might consider this one.

This is several years old, but appears to be built well after I inspected the internals.... of course.

RV Air Pump_03.20.15 by Fantinesvoice.com, on Flickr

I have a plug which goes into the RV outlet on the back of my Dodge TV. Along with this I use a 50 foot air hose. One point to be made is that if we use long electrical extension cords, the voltage drop is not good. However, a long air hose has no issue as the air pressure is evenly distributed throughout and there is no loss even in a hundred feet.

Having said all that, this pump was designed for motor cycles, and I suspect it may take awhile to inflate a vehicle tire. I may even do a test run, now that I have wired it for the truck.

I found one here: http://www.sears.com/slime-slm40019-...SPM11206261119

I think this may be a good one as well... much faster:

I had one of those, but I burned it up (I think) by running it too long while winterizing one year. No problem filling tires even to 80 PSI. It was a really great compressor...I really should try it to see if it still works or not. (And if it doesn't, trash it and get a new one.)

Ran it today - the air was coming back out the inlet! I opened it up, and there's not much to it. The motor runs a piston that sucks air in one hole and pushes it out another one. I think there is supposed to be two thin pieces of metal - one on the inlet and one on the outlet - that lets it build pressure, but in mine the metal piece on the inlet holes was gone. There was some debris in the cylinder but not enough to account for the size of the metal piece, assuming it was the same size as the outlet piece. I would've taken pictures, but my hands were dirty. So I don't really know why mine failed - the thin metal piece broke for some reason, but I couldn't figure out why. It didn't seem like it was anything I would've done to cause it.

There's no electrical way that the pump would stop if it built up too much pressure. Seems like there's some max pressure it would build based on the volume of the cylinder when the piston is at the top of its stroke.

Still kind of want another one.
