This is the 3rd 12V Air Compressor of this type that I have ordered. The first (2) were from different sellers and would not pump up my RV Tires past 95 lbs so they were returned. This compressor seems to work well and was able to inflate my tires to 110 lbs with no issues. The only thing I found negative is the alligator clips for the battery are flimsy and bend easily and the tire pressure gauge is not accurate. I have a separate pressure gauge so that is not an issue for me.

I returned as it was just to heavy and large for my needs. Yet it is a terrific product and powerful. If you are ok with the weight his is a great
product.

Great product.

This compressor appears to be sold under a few brand names and at various prices. The pictures are the same. I chose this particular one because of its cost.

Now to the compressor itself: I chose this because it has the highest output that can be used for a single tire. From my understanding, a single Shrader valve (standard tire valve stem) can handle about 7 scfm. The twin piston pumps start at around 10 scfm. My primary use will be to fill all four tires of my Jeep at the same time, but I'm willing to have it take a little longer to air up if I can use it to air up a single flat tire. I took a short trip to Colorado and used it to air up three times. It did a good job. I wasn't paying a lot of attention to the pressure gauge (I watched the pressure display on the dash to determine when to shut off the compressor), but it agreed with the on TPMS display fairly well. The clip on attachment worked and would be a time saver if you were airing tires up individually, I chose not to use it so I could have less restriction to air flow from an additional Shrader valve in series ( the clip on attaches to the main hose by a screw on Shrader valve).

Pay attention to the fact that at sixteen pounds, this is not a lightweight compressor. It is solidly built and has the heft that comes with that. The case did not require a perfect placement to get everything back in and appears sturdy enough for my occasional use. If I was using it every week I wouldn't expect it to hold up for several years. The compressor did get hot as expected. I pulled the rubber cover back from the connector on the hose and wore a glove to get a good grip and remove the hose. The clamps attached to the battery securely and the cord did not heat up while the compressor was running.

I used one of the inflation harnesses that uses 1/4" coiled tubing and plan on upgrading to a larger tubing size to make it easier to handle and maybe shave some time. I did notice that it took longer to refill my tires at 10,000 feet than my trial run at home. Since the air is much thinner at altitude, that is to be expected. Since this was my first rodeo with airing up at altitude, I didn't know how much change in pressure to expect when I went to lower elevations. The Jeep's tire pressure screen is set for 37 psi and the tire pressure flashes when a tire is below that. I aired back up to 37 psi the last time at about 8,000' and my pressure on the drive back to Texas was in the range of 42 psi.

In summary: I'm pleased with my purchase and expect it to meet my needs and have a good service life. I will probably DIY a custom inflation harness that will connect directly to the compressor but will keep the supplied hose and fittings for inflating single tires or assisting another vehicle if needed.

Airs up my 32" tires from 15psi to 30 in 60 seconds.
Make sure to run the vehicle while useing the compressor.
