air compressors

Usually if it clamps on the battery terminals it will do fine. Cigar plug? Probably weak.

I use an MV-50 for light use over the last 15 years.

I carry a hot dog compressor from Harbor Freight, 120 volt. It has worked fine for truck and trailer tires. Around $50.

I have a VIAIR. rated to 120PSI. Never took it that high but I have used it to set truck tires to 80.

Look for one that uses alligator style battery connections not a cigeratte lighter plug

I've got the Milwaukee M12 inflator, handles 65 PSI just fine but I don't have any 80 PSI experience. I did inflate a gentleman's spare that was reading 0 PSI when I hooked up to 65 PSI with just one rest (hose was starting to get hot so we mounted the tire while we waited, by the time we were done jacking the corner higher and putting on the lug nuts it was cool enough I was comfortable enough to go from 55 to 65). I'm using 6 Ah batteries I bought off Amazon for $40 for 2. It's not the cheapest solution but it's probably the smallest that can handle RV type pressures, combined with the ease of use vs corded units I thought it was well worth the investment.

I just topped off the tires today to 85 psi on my A. Used this little
Kobalt.

Took my 19.5's up 10 lbs in less than 5 min each.

Let’s be clear, while I’m happy with my Ryobi, I use it to bring tire pressures up to the desired level. Not to inflate a flat tire.

Depends on how much time you have on your hands..

Very small compressors = very long time to pump up to high pressures in large tires.

Medium size compressors = shorter time

Industrial size = extremely short time.

12V?

120V?

Tank?

No tank?

all makes a difference..

For small high pressure tires like a bicycle tire a simple $10 12V compressor like this..



on at Harbor Freight can fill a small bicycle tire in a minute or so..

A large truck tire to 80 PSI would take considerable amount of time but possible with a lot of rests.

There are more robust 12V air compressors which can handle higher pressures better but you are looking at $75 and up for those and still may need to rest the compressor..

Most 12V compressors are tankless and often are slower to fill tires.

HERE is a search for those at Harbor Freight..

There are tankless 120V compressors out there, they tend to be slow filling like 12V tankless versions..

120V tank versions there are a lot of those that can easily fill large tires to 80 PSI fairly quickly and the tank gives a reserved supply of air that helps the compressor cope with the amount of air that larger tires take.

You can find a variety of those HERE

The larger the tank, the easier and faster it gets for filling tires. Small pancake or hot dog styles are nice for portable use and often can be stowed away in a RV..

Ryobi, battery powered and I recharge while driving with the 1500’s 120 volt plugs.
