Vair makes ones between $50 & $300. They generally look similar in photos. The more expensive ones are a lot more powerful & unsurprisingly pull a lot more amps. Pile of different accessories, auto-shutoff & permanent mount options too. Obviously bigger motors in the bigger ones, but probably bigger pumps too. They have varying duty cycles as well. They have charts with pressures & CFM on them, so you know the actual capabilities. Nice comparison guide on their site somewhere too.No, actually, it's not.
The Viair 78P which was the top rated compressor in the Wirecutter review that PhysAssist linked is currently on sale on Amazon for $38.25 (regularly $45.95). That sale price is just a couple bucks more than the HF Pittsburgh 100 PSI tire inflator. The Viair 78P also has a 30 minute duty cycle at 30 PSI. If my wife's car had been able to handle the 15 amp rating on it, I'd have jumped on it. (The larger 88P I got for my truck runs $59.39, and is well worth it if you are inflating large tires.)
I have a 400 automatic on my Christmas list. Would like to permanently mount it on the truck, but not sure how likely that would be if I even get one. A bit overkill, but I hate fighting to turn them on & off, that the smallest auto one i saw.
