Sounds perfect for me.

In the review I posted about that particular portable unit, My only question ( and I don't know for sure about this) would be the rubber gaskets. They may not be suitable for petro solvents and spirits. That leaves out lacquers "if" so. Properly thinned acrylics should work well though. And that review is aging, there may be solvent capable ones available these days. But then, I suppose, in an apartment environment, most folks these days would likely be using acrylic paints anyway.
Edit: Many of these portable airbrushes can have a hose added between the battery pack/compressor and the airbrush. I saw one unit that generated 48 psi. In a situation like that, it seems possible a pressure regulator could be added. Depends what the flow rate is. IE, it might generate 48psi but under work loads, air flowing it may and probably does drop way out from that optamistic number. Just sayin.
