Battery operated air compressor --small

I had several of those cheap 12V pumps and they usually are good for couple of 35psi tire inflations.
Than few years ago I bought Firestone pump design for air helper bags.
I made it portable and used on 90 psi trailer tires and air bags at least 20 times and is still pumps up.

Roy B I have the same one works great
I have had it for over 5 yrs :)

For me the Q Industries MV50 Portable 12VDC Portable Tankless Air Compressors (AMAZON) works just fine. I can air-up my trailer and truck tires and also use it for blowing out my water lines in the trailer when the temps drop below freezing...

I have used this model from way back in my Jeep/tent camping days.. Stores easy in its own carry bag and fits under my truck back seat area. I can sit this on my dropped tail gate of the truck and connect directly into the trailer battery bank terminals. The long hose reaches everything from this spot.



I use this adapter from AMAZON to connect to the city water port to blow out my water lines in the trailer and then fill the P-TRAPS with RV pink stuff. With the tankless compressor the pressure is slow to build-up which allows to get to the spigots everywhere to drain the water out without fear of over pressure on the lines.



Great small footprint items to have around for my off-road trailer...

Works great with my OFF-ROAD POPUP trailer and F150 TRUCK Tires. I can air up 65-80LBS real easy... The MAX air is rated at 150lbs. As old as mine is now I doubt I could ever get that much haha...

I carry an air tank. Works quickly, doesn't need a 12v connection and has enough volume to at least partially fill a truck tire in a pinch.

As a CG Host at a National Park site with no hookups I was popular with the air mattress set last summer too. :)

I have one of these and it would do the job I think:

Runs off of the Ryobi 18V Lion battery system that can power any Ryobi tool...

A hand pump works well on bags since there is little volume you need to fill.

Viair is probably one of the better 12 volt jobs.
