12 volt air compressors

So the one from Amazon is not the same on that I bought. It is the one that isn't controlled by a computer of sorts. Mine you set the PSI and walk away.

It only took about 10 minutes to fill my tires from 12psi to 30psi. So a 30 minute run time is not an issue.
 
I bookmarked this monster a while back. Seen it on YouTube. 80 amp draw. 8 out of 10 min run time. Probably pretty expensive. http://12-voltair.com/products_12v6cf.php

This one looks really cool! https://www.extremeoutback.com/product/extremeaire-high-output-12-volt-compressor/

Continuous duty but the cfm is pretty low at 100 psi. You also probably don't need 100 psi real often. I would just set it up with a tank for sure.
I've used the Extreme air unit before. Borrowed it from Larry for a couple of trips. His came in it's own toolbox. It's massive. But it fills tires in no time. Truly a beast. The downside is the size. The toolbox takes up a ton of space.

wrong one was listed; Amazon does have it
 
Used it in Moab this last weekend. The hardest part about it was setting it up, it wasn't hard to set up just took a minute cuz you have to you know take the valve caps off, once it was set up it worked great no issues.

Steven Watson and I talked about maybe running like shorter hoses to a central system with connections near each wheel with the compressor plugged into a main line or something like that.

Would not be hard to make the system the only benefit would be not having the coil up the longer hoses.
 
I built a 4-way setup, with a stop at Harbor Freight and some parts on-hand. Basically it's a manifold that has a standard air-tool fitting and a ball valve as an inlet, a pressure gauge on top and then 4 yellow plastic hoses going out. At the end of each hose is a valve stem clip, kind of like this:

These theoretically don't leak when they aren't attached to anything, so you can use the system as a 2-way or whatever. This also works for airing down and puts all 4 tires at the same pressure. I don't recommend those clips, as they like to pop off. I'd like to try something more like this:

To preserve the normal "just air up one tire" hose from the compressor, I soldered a brass valve stem fitting to some brass fitting with NPT and attached a standard air tool quick disconnect. That's what connects to my manifold described above (or whatever else).
