I ordered a Fini today. It has the pressure I need at a reasonable level in a small package. I looked at a a 6 gal today but it was just too big and heavy. Thanks for all the ideas.

Everyone has different expectations and needs, so what works for someone may not be "the best value" for someone else. That said, I saw the FINI at Lowe's 3 or 4 years ago, pondered about it until the sale ended so I didn't buy it. Saw it on an Amazon "lightening deal" a year later, said, "What the heck" and bought it for around $60. When it arrived I was very surprised at how fast it reached pressure and how well it worked to air up tires on our truck and trailer. Danny and I talked about it a few times and he bought one. From what he's posted, it sounds like he's also impressed with the small size and capability of the FINI. There are a couple of clones that use a different compressor head, so I can't speak of their performance, but the "red FINI" is a surprising little compressor that should have the logo, "The little engine that could".... No, I'm not a salesman for FINI, just a satisfied user of their little beast.

I think you'll be very satisfied so long as you consider that it's not a 6 gallon pancake and don't expect it to act like one. For a little guy, mine is the "go to" for most quick jobs where I don't want to roll out the 35 gallon "big guy".... I haven't even powered up my DeWalt 6 gallon pancake in 3 or 4 years now, even installing an asphalt roof, this little one keeps on perking without a hiccup.

You would be correct John. When I bought it I was worried about its abilities. When I first pulled it out and saw how small it was I became more concerned and figured it would be like a lot of the other smaller compressors I had purchased and would go on a shelf somewhere. Nope. I was very impressed when I used it to air up the tires from 65 to 80psi before we left. I had bought the little clip on ends that hold the hose to the valve stem for use with the Viair and used them with the Fini thinking it would take some time for it to air it up (I've smoked a smaller electric compressor trying to air a flat up). Poof! Before you know it the tire hit 80psi. I was impressed and still am to this day. It is SO convenient compared to the pancakes.

I am not a salesman for Fini either, just a happy customer/owner. As John mentioned, different folks have different expectations. This will not work like your or my shop compressor, or even a 6 gal pancake - it doesn't hold that much air, but for topping off tires and such it is awfully handy.

I had the Craftsman version of the Air Boss. It was the same as the Fini. It was a great little unit and lightweight. Plenty of pressure and pretty quick to fill the tires.

The only things I didn't like were how stable the base pads kept it standing, and it required 120VAC.

Just bought the fini on amazon. I've been looking at it for years. Had a low tire alert on the trailer a month ago while in the middle of no where. Had to go real slow for 80 miles until i found a tire shop. Not doing that again.
Do you think i can run this off the 110 outlet in the truck?

I'm not sure which truck you have, but if it's a "last generation Ford" (2011-2016) the inverter is rated at 150 watts. The newer generation is rated at 400 watts. Neither will provide enough power for the FINI compressor. So the answer, at least with Ford trucks is NO.....

That said, the FINI compressor is rated at 9.5 amps at 120 VAC. That equates to 1140 watts. So it'll take a 1500 watt inverter to operate it for any "lengthy time". You may get by with a 1000 watt inverter, but I'd suspect it wouldn't last very long before you either overheat it and start having "cutout problems" or start blowing fuses on the inverter. That size inverter requires a direct connection to the battery (no cigarette lighter plug will carry that amperage) so you're looking at either a "large, permanent inverter installation" or a "battery cable clip on connection" to support a 1500 watt inverter. Comparatively, the 2000 watt generators we all use (Champion, Honda, Yamaho or others) are rated at 1600 watts continuous/2000 watts surge, so you're looking at a comparable inverter system which costs about as much.

My recommendation, if you have a 2000 watt inverter generator, just plug the compressor into that if you're in an isolated area.

But, back to your initial question. No, you can't plug anything that draws that much power into the small inverter in a vehicle.

Nope, exactly why I ended up with the cordless. We were dry camping. I had just put the Honda away. Then I thought about adding air. . .

In August, I picked up a Klutch tire inflator from Northern Tool & Equipment. It is a 12V, 45 amp unit that is rated at 150psi and 5.3cfm. My decision for a DC inflator was based on a worst case scenario of being on the road or dry camping and needing to fill a spare up to road pressure. The only drawback is that the cable provided is a touch short for reaching the off battery side of either the truck or the 5er; so jumper cables are a must. The other thing that I dislike is that the connector for the tires is a screw on type. Other than those items, it works well at topping up tires quickly and boasts a 20 minute run/30 minute cool cycle.

2018 Ram 2500. I'll check and see what is rated at. I don't always take the generator if we don't need it camping.

When a tire loses 20% of the required pressure it is considered "Flat" by the tire industry and should NOT be driven on. While you might be able to travel down the road at a reduced speed you would most likely be doing permanent damage to the tire structure which may come back to bite you weeks or months later when the tire suffers a catastrophic failure.

How low a pressure obviously has an impact on how much damage is being done.


You also need to remember that the companion tire has to "pick-up" part of the load so you could be doing damage to that tire too.

Safety Warning

It is one thing to need to add 5% to 10% of the pressure needed to "top-off" your tires. If however you have lost significant amount of air (20% or more ) and had been driving on the tire before discovering it there might be damage to the tire structure which could result in an explosive rupture when re-inflating.
This is especially true for steel body tires. A tire shop safety cage is the ONLY way a steel body tire should be inflated if the tire was ever run with low air.

110 psi tires OE?

One question. Did your 110 psi tires come OE on your trailer or did you "upgrade" your tires?

I get the point and passion, but are you only talking about trailer tires? I would just pump it up on the side of the road and drive it. I am pretty sure 90% (Dilbert estimate) of people would not replace the tire because it went "flat" at some odd percentage of full inflation. Which, BTW would only be 6 lbs low, on my Subaru by your 20% number (if this is all tires). If I did decide to replace it, I certainly wouldn't even replace it until I got back home. To me it sounds like an anti-lawsuit nanny state answer, versus a common sense recomendation.

If a tire goes low and there is ANY road wear on the sidewall REPLACE it.

This happened to ME...tire went flat/rolled off the bead of the wheel on my car hauler while my off highway Jeep was on it. I put the spare on, took the flat in to Discount Tire, the 18 year old expert there examined the tire, said there was nothing wrong with the tire, remounted it and aired it up for me. I threw it in the back of my Jeep Cherokee, I made it about half way home and the tire EXPLODED...scared the bejeezus out of me.

Understand, but what you described is far from 20% under-inflation.

The 20% is an often stated number. This applies to all tires.


The average user is not qualified or equipped to properly and completely inspect a tire that has been run when low on air and make an informed opinion on the long-term durability of the subject tire. The 20% figure is the arbitrary level of underinflation where years of experience indicate that the tire has probably been damaged enough to result is a significantly shorter life ending a probable structural failure.
Obviously, some tires can be run at a lower level and not fail while other tires may fail even if the inflation had not dropped to the 80% figure. What was needed is a guideline. What hasn't been discussed on how far the tire was run underinflated. Before the introduction of TPMS some tires might be run hundreds or possibly thousands of miles underinflated. A better answer might be a chart of miles vs underinflation but that requires a lot more data and also requires that a TPMS be used and followed.



The concern is not just based on the possible lawsuit but on the possibility of personal injury to others.


Cars are a poor example as many have significantly larger reserve load margin than almost all RVs with many RVs having negative reserve margin so in the RV the 20% may be too conservative and a loss of 10 to 15% might be more appropriate.

From a corporate perspective, that is the definition of concern of a possible lawsuit.

For compressors, volume CFM is as important as PSI. I have a compressor that will pump 275 PSI, it will fill a car tire in about three days. CFM is important, I don't have tires that require 100PSI (except my bicycles) for me 125PSI is enough.
