Default Portable Air Compressor

OK, y'all have convinced me that a portable, 12 volt air compressor would be a very handy addition to my camping equipment lineup. I am assuming that the $ 19.95 ones are not worth the trouble. My primary need is to be able to re-air the TM tires after repair or pressure lowering on rough roads. Also, I'm hoping to find an acceptable compressor for under $ 100.00. Any suggestions?

I use this one:

It has worked well for me so far. Screw-on chuck, fairly fast, fairly quiet, and the gauge on it is even removable.

Default Air Compressor

I bought a Black and Decker air station at Lowes. It works on 12 volt and 120 volt. It cuts off at set pressure also.
Here is a link to Amazon.com

This Ryobi cordeless compresor has worked very well, for our TM, truck and anything else wanting air..

OK Dave-(Screw-on-chuckj) I have had compressors that have a fitting that the handle flips up to remove-but in doing so you lose most to the air you put in and some of the air that was already in the tire or air mattres or beach ball or anything. Do you lose air when you unccrew this tool?

Yes, a little bit. But any air compressor will do the same thing. You get minimal air loss out of the hoses that just press onto the valve stem, like at the gas station. But unlike the huge gas station compressors, a portable 12v compressor delivers such low volume that it takes much longer to fill. I'd be annoyed with having to hold the thing on there for a few minutes.

So I just pump in a psi or two above what I'm targeting for, and release.

Mario:

Sorry about the dumb question, but how do you get 18 volts from your car battery?

It's not dumb, I think most of the posts on here are about compressors that you plug into an AC o DC power souce. So that makes my suggestion a little misleading. The funny thing is when I first read this thread my thinking was "Why are the using 12 V rechargeable when 18V is so much better.. ? ". It's all a matter of mind set.

The Ryobi compressor uses 18V rechargeable batteries like those for a cordless drill.

Which then brings up the question.

How do you recharge those 18 volt batteries from the 12 volt batteries on the TM or in the tuck. Or do you always take your generator with you? I have no shore and no shore power.

If I deflate 8 truck tires and 4 trailer tires to drive in the sand, will that charger air up all 8 truck tires to 75psi plus my TM and ATV trailer tires?

How long do you think it would take to air up 8 truck tires from around 30-40 psi to 75 psi?

I'm interested in covering the situation where I drive in sand with very low pressure and then get on a freeway.

Those small air compressors take forever to fill a tire. The one that I have says it will fill a 13" car tire to 30PSI in 8 minutes (ya.....right). If it does fill that tire in 8 minutes, it will take about 20 minutes per tire to take your truck tires from 30# to 75#. If you have 8 tire, you'll be there for about 2 1/2 hours. It may be slightly less if you have a large mini-compressor but a mini- compressor is a mini-compressor and they just are not designed for what you are talking about.

If you have all that off-road stuff, you may want to invest in a generator and a 110V compressor with a 2hp motor and 8-10 gal tank......like this one:

Even that compressor will take a while to do the job that you are asking.
