Tire Inflator

I would like to hear anyone's thought on tire inflators. 12v. vs. 120v. I do have a generator onboard but I'm open to all recommendations. Are 12v. too light and slow. Cost vs. efficiency. Size must be considered for storage. While we are on the subject of tires. What works best for tire change. The tire aid looks great in concept but some say it still doesn't get the bad tire ground. Am I better off w/ a 12 ton bottle jack for my fifth wheel. Would appreciate all comments. Thanks.

JMHO - I carry an air tank with 110psi pressure inside, instead of an inflator. If I was to buy an inflator, it would be a 120V. 12V are somewhat slow.

As for changing tires, I carry a TrailerAid. Have not had to use it on the road, but did try it at home, and it lifts my fully inflated tires off the ground just fine.

I have a 120v small unit on the road for topping off tire pressure. Not fast, but I am not in a hurry. Also works for bike tires.

I carry 2 x 10 leveling blocks and 2- 6 ton bottle jacks. I have changed many tires with that combo. Pull the good tire up on a few, then use the bottle jack to lift the axle a few inches to allow the blown tire to be changed.

I just bought a Craftsman Model 15309 (recommended by several forum members) after about a week of internet searching and store shopping. It's 120V and has a 1.5 Gal tank. It does an excellent job of quick inflation on my 75 - 80 lb tires.

Storage space is also an issue for me, and this unit is bigger than I wanted, but I didn't see anything smaller I trusted. IMO the 12V compressors are over worked and fail quickly. The attractive feature is their size.

Also, there are some good threads in this forum about maintaining tires. If you do a "search", you'll get some good ideas.

Being an avid tent camper from days past I learned to carry the 12VDC TANKLESS model portable compressor - The light weight compressor and all accessories all fits in a small tote bag...

I use the Q Industries portable MV50 12VDC 150 PSI Air Compressor for airing up tires and with the CAMCO 36153 Blow Out Adapter for blowing out the water lines... Since this unit is tankless it slowy build up air pressure which makes it very safe to use for blowing out plastic water lines. Everything available from AMAZON

I too have a generator but having the portable 12VDC version compressor fits my PLAN B situations much better.

This 12VDc compressor being setup on the tailgate of my truck when in travel mode taps into the 12VDC batteries on the trailer tongue can service all tires both truck and trailer..

This unit is also my source of air for BLOW OUT of the water lines when unexpected cold nights catch you off-guard by connecting to the fresh water inlet using an adapter. The compressor without the AIR TANK builds up pressure slowly and allows me to walk around to all of the water spigots to blow out all water lines. I can winterize in a very short time frame and can revert back to normal by just adding water to the tanks.

My 12VDC tankless compressor serves the kids at the camp grounds for airing up their bicycle tires and on a few occasions aired up some air mattresses for the tent campers... When the word gets around you become king of the neighborhood hehe...

I carry my 12VDC compressor under the back seat of my truck

x2 on the 12V version. I carry it for off road conditions or dry camping situations. I also have a 120V pancake compressor, but do not travel with it. You need to look at the delivery rate to compare models too. 120V or 12V is not the only measuring device here. I have the same as Roy above and it does fill my E rated tires to the required pressure in about 3-4 mins from 20PSI.

You might not want to do this but I use a hand pump. I have a very nice shop quality hand pump that we use on our road bicycles. The pump is not even working hard to do the low pressure of RV tires, it's designed to do 120psi with ease. It also has a very good gage built in. I have shop air at home with 100 feet of hose and I still hand pump my trailer tires.

I like my 12volt as is easy to store. And all the kids in the campground know that I have it. If would charge for ever bike tire that I have filled wouldn't cost to much to camp. But I don't.

I looked at inflators but since we need 110 PSI for our tires, I went with the sears 1.5 gal compressor, it does a great job.
