    I did a driveway test with my 2 pumps about a month ago. Aired 2 of my 35s down to 15 psi and aired them back up to 32 psi.

    My MF-1050 pump (2.3 cfm) did it in 4:21. My Smittbilt (5.5 cfm) did it in 3:23. This was in Denver at an elevation of 5500 feet.

    this was only 1 tire for each pump. I know the MF-1050 slows way down when it gets hot.

    I’ll be curious to hear how yours performs.

    I have the rectangular shaped Ryobi 18V inflator so I don't have to use power from my vehicle. It works just fine, and is speedy enough for me. I have an RV and it was able to get the pressure up high enough for those tires.

    I went with the DeWalt (similar to the Ryobi) because 65PSI is all I'll ever have to fill in my current situation. Works great and can also inflate low pressure applications. Never seems to overheat.

    I’ve had a few of the 12v pumps die unexpectedly or suddenly not want to inflate past 20psi so I keep a small bike pump in the trunk for real emergencies. It could take hours to fully inflate all four tires but you’ll never be truly stuck. Roadside bike pumps are $20-50

    The Air Dragon. I found this at Ollies for $16. Plugs in to 12V or has a built in battery. It has a long cord and a nice case. It stops at the pressure you set on a digital screen. Inflates very fast.

    My Expedition picked up a nail last week on I-95 coming back from Florida. I spotted it in NC and it was fairly fresh (some of the nail was still protruding, bent at an angle). The tire was still holding air, so I left it in and picked up a compressor and a plug kit at the next Advanced Auto that I came across. The brand they carry was "Slime". Ugh, Slime, what a name for a compressor co. Well they also make that Green tire sealant goop that can be used. Well, while I don't use the goop, I did not want to be caught without a compressor if the tire started to lose air. They had about six models of compressors from the $19 Variety to a $147 dual model.

    I decided that I was ok with their "Elite Heavy Duty" model which came in around $79. So I put it the truck and kept on rolling. Well I made it home to MD and the next day pulled the nail and plugged the tire. I broke out my $79 Slime Green Compressor and decided to try it out. I was surprised to find out how much I liked it. My other compressors are not very impressive, so that isn't saying much. But slime model had the Digital gauge, preset fill limit, was relatively quick, and was much quieter that my other compressors. I did not like that its power cord was not very long. I was able to reach the rear driver side wheel from the Expeditions rear outlet, so the cord is "long enough" for this. But my other compressors have like 20' cords. The Slime does come with a curled up green "air hose extension" that will give it more reach.

    It did also come with a small nylon case/bag to contain it when not in use. I like that so I can keep in the truck with its cords coming undone and spreading around (like my other compressors) despite how I wrap them up. I like the digital gauge too as my other compressors have that small 1.5" dial gauge where the different between 20 - 40 PSI is tiny area of the face and I get down in there to see if I'm at 31 or 37 PSI. This one I set it to 35 PSI and turn it on and it will cut off when its at 35. No guessing when to stop the compressor, no having to run again for a few mins because you were 2 PSI short, no having to let air out cause you left it running too long and now you're at 39 PSI. Nice. Plus it was quieter. Its not silent, but I would have to walk away from the others to have a conversation, but this one I wouldn't have to. Nice again.

    I can't speak to its longevity, but so far, like I said, I'm surprised at how happy I am with this one.

    I used to buy whatever was available that pumped air. After them not working at the most convenient times (sarcasm), I tried a viair 84 (with the battery clamps) around 4 years ago. Was quite happy with it. My father pulled rank and acquired it from me. Got another (cig plug), wound up giving it to my aunt when her other brand quit working. I now have my third that stays in the wife's car or goes in the boat when we're gonna be using the atvs for hunting (travel to where the atvs are parked is by boat). I will be adding another viair, probably the 300, to keep with me and stop borrowing hers. lol
