The other thing about those little units is they don't deliver a lot of 
volume.  There's pressure, but not enough moving air to blow away much dust.

Before I bought a real air compressor, I used a 7-gallon portable air 
tank and filled it at the gas station.  I've heard of using an 
inner-tube, too, as an air source for air brushes etc.
