Well,
The way I look at is, we're not trying to fill a 22.5 from ZERO pounds pressure to 120 psi. All I think the OP and many of us are trying to accomplish is "topping" them off. Other than a large industrial compressor with a massive storage tank, i.e. truck tire shop, any repair facility etc. ANY compressor, be it the one on most diesel pushers or, even the small, 120VAC ones that have been mentioned, will have a hard time putting a large amount of volume into either a 19.5 or 22.5 tire, from a low pressure starting point.
But, if you're running say, 95 (just an example)(per established weight measurements) and your tire is sitting at say, 90 in the morning, the 120VAC unit will work just fine. And, if you don't mind running the engine and want to use the engine driven one, it will work too but, a bit more noisy.
Unless a tire or set of tires has some extensive leak(s), it won't drop that much anyway so, "topping" them or one off, is not a big deal with a smaller 120VAC unit like the Sears or Porter Cable unit that I and many have.
