Portable air compressor?

There are only a couple of decent 12 volt compressors, and they pale in comparison to the cheapest 120 volt pancake compressors.

Have used a Craftsman version of this one for many years. Easily brings my tires up to 80#.

Have you noticed that your profile's Jayflight picture is upside down?

I am OFF-GRID alot with my camper setup and having a portable air compressor is a must have item.

I use the TANKLESS type 12VDC Air Compressor that comes in a small carry pouch and keep it under my truck back seat area.

I can sit this on the tailer tailgate of the truck and can walk around to all tires with the long air hose. Sitting on the truck tail gate allows me to hook into the trailer tongue mounted batteries...

I also use this tankless air compressor to do a quick blow-out winterizing when camping late in the season and it gets way below zero temps...

I agree the tankless type air compressors are not the most robust but it gets the job done for me airing up my tires in the high 60s and low 70s air pressure. Mines gets pretty hot as well pumping away haha... Always have to remember to wait until it cools down before stowing away in its carry case...

I become king of the camp grounds when the word gets around I have a working small air compressor. Kids always glad to find some air in the campgrounds...

I have used this type of tankless air compressor alot back in the 50s and 60s when I was getting off road alot in my Jeeps... We always liked to air down the tires to get more traction. Then you had to air them back up....

Mine is the Q Industries MV50 SuperFlow High-Volume 12-Volt Air Compressor AMAZON and they have a couple of similar same quality like compressor listed...


AMAZON also lists the VIAIR models that are popular units...

I use one of these air adapters from AMAZON to blow out my trailer air lines... Screws into the city water port.


The beauty of using a tankless air compressor it does not come up to full pressure as soon as you turn it on. This gives me plenty of time to start the tankless compressor on the truck tailgate and do a walk-thru in the trailer turning on/off the various spigots blowing out the lines down the drains - then I add a little bit of the pink stuff to the p-traps... Then I drain the fresh water tank...

A must have item for me in my OFF-ROAD POPUP trailer operations...

We use a Viair 90. Perfect for airing up the trailer tires to 65 psi. Not sure I would use if to pump up my truck tires to 80. Never tried.
Viair 90p

I've had pretty bad luck with 12VDC tire inflators. They don't seem to last long or work well.

However, I've had this 110VAC inflator for many years and it works just fine. Loud but durable and effective. Picked it up at WalMart.

I have a Viair 300P. It will easily hand 65 psi. It runs off 12v. The advantage to a 12V compressor is you may not always have access to 120v.

I am looking to get an air compressor for my next trip. Does anyone have a suggestion for one than will handle 65psi.

Why just buy a compressor? Buy one of the all in one's that can do a whole lot of things when RV'ing.

Airs up tires, jump vehicles, charge electronics, runs small TV overnight without charge and to power a lamp in the RV when I wanted to save my coach battery.

I think I've helped about 20 other RV'ers over the years with this little powerhouse.

I have one of these on board at all times when I travel.
I don't leave home RV'ing without it. :C

The best for RV use is the Viair,12 volt and will put out at least 120PSI. More than enough for your needs.

I use This one

120 volt compressors are great but are noisy and of course, need 120 volts. I took my Porter-Cable on a long trip last year and one morning I needed to add air before the end of quiet time - it's very noisy. We drove off down the road looking for somewhere to plug in and didn't find anything until many miles later when it was too late as the tires had warmed up.

Not sure how noisy 12 volt compressors are, but you can always drive a short distance away from fellow campers to air up.

Viair is top of the line and makes a number of 12 volt compressors. If you want one of theirs, check the specs and duty cycle. The "P" series are the portable ones. The 90P has a 15 percent duty cycle, the 400P is 33 percent and the 450P is 100 percent. Great compressors but expensive. Their two RV versions have extra hose and an extra accessory or two and are the same as the non-RV models. The 450P-RV is over $300 on Amazon.

Q Industries has an MV-50 model which has a lot of positive reviews. Costs a lot less - $73 on Amazon for ex. IIRC, has a 40% duty cycle.

Am currently on the hunt for a 12 volt compressor and if I can't find a decent price on a Viair, new or used, will get the MV-50.
