Interesting product. Kind of spendy, though, IMHO.
Carbon dioxide tends to diffuse through rubber comparatively easily, so it's not ideal for filling tires, but would certainly be far, far better to driving on underinflated tires. (They might need topping up a little bit more frequently is all—nothing major.)
I have a Fini AirBoss 120V compressor; this is a nice small compressor and works very well. It's probably overkill for topping up tires, truth be told. If I need to add some air to a tire on the road, I'll just have to use the generator that the motorhome already has. While it has a built-in tire valve doohicky, I do bring along a proper dually chuck to use instead.
The 12V mini tire pumps that plug into a lighter socket are nearly useless for motorhome tires; you'll be listening to a hellacious racket for a long time before you get to 80 psi. They're barely sufficient for car tires. I think I would rather use a good bicycle pump than one of them—it's quieter and quite possibly faster.
