Portable air compressor

The manufacturer recommends I keep my RV tire pressures to 110 psi. What is a good portable air compressor that is battery operated that will do the job?

Dewalt DeWalt 20V MAX 20 V 160 psi Inflator.
Battery, 12v cord or 120vac adapter.

I also use it with an adapter connected to the freshwater port to blow out the water lines when winterizing

Takes up more room than what I like, but I use a Craftsman 6 gallon pancake air compressor I already had on hand for utilizing a pin nailer out in my woodworking shop.

I have a slug of Ryobi 18v tools so also have their compressor. It’s worked great for keeping the truck and trailer tires topped off and also air beds or floaties for swimming. It does 110psi nicely.

Check out Viair portable 12v compressors. Not battery powered but has long leads with alligator clips to quickly connect to your RV or Truck batteries. The new RVS series are specifically designed for RV users. They are pricey but very high quality.

This one is 1.2 gallon. Small and handles 110 lb tires. Carry it everywhere. Use for tires and air hitch.

The one I bought wasn't bundled with nailer.

Not battery operated, but I also have a Craftsman 6 gallon pancake air compressor.

I had a Harbor Freight one I purchased about a year and a half ago. It worked fine a couple times and then it wouldn't pump air any more. If I disconnected the hose, it would spit air. When the hose was connected, nothing! I replaced the connection with two different quick disconnects for the hose. Nothing worked. I threw the thing away and got a Craftsman. And, I've had BAD success with everything I've purchased from Harbor Freight. I'll never buy from them again for anything.

I carry a Porter Cable 120vac 6 gal. compressor along with a ViAir 400P for those times I don't have 120vac. The 12vdc compressor will work wherever you are but you have to get it connected to 12vdc. The pancake just plugs into the outdoor outlet and I can air up the truck tires after I have aired them down and top off the trailer tires when required is stationary. I "could" get by with just the ViAir but I've got plenty of room and the pancake is so much easier to deploy.

I use a Kobalt Quiet Tech and it sits in side storage compartment and plugged into a 120V receptacle at all times. Carry a 50' air hose to reach anything I need it for. In the case of not having power I start the generator.

I also use the ViAir but modified the plug so I can utilize my trailer plug instead of messing around with the clips.

ViAir for me. A little pricey but works like a charm

We have gone from pancake to ViAir to now Milwaukee 18volt. Most convenient ever IMHO.

Viair 450 RV is what I use. I love it. Its 12v so it runs off camper batteries, or the truck.

Another vote for the Vlair. Don't have one in the RV yet, but we put one on a 36 row JD (Precision) planter to keep 36 individual air bags at about 30 PSI (depending on conditions) for down force on the closing wheels.

I never thought it a viable option, but the little thing has ran 2 seasons now, sometimes 18 hours a day in an insane dusty environment for 5 or 6 weeks a season now, and shows no sign of quitting! Amazing little compressor.

We did upgrade the air filter system right out of the gate because of the dust.
