A portable air compressor comes in many shapes and sizes. We are only truly portable if we don't get too big. As long as we can be moved around easily and used where needed then we are considered truly portable. Once we get too big, then we are relegated to shop work and other stationary jobs. I pity these poor fools. It would be boring to just sit in one shop all day. I like getting out and seeing different places and meeting different people. I think it keeps me young.
You will need at least one regulator and a water trap in line before the regulator. These are not costly. A regulator allows you to set the correct air pressure for the tool you will be using (say, 80 PSI) instead of tank pressure (say, 175 PSI).
I returned to the job site with my new goodies and soon discovered that I had indeed made the right choice. The compressor started right up and was soon pressurized and ready to go. I hooked up the hose and gun, filled the reservoir with stain, and started systematically applying it to the siding. The portable air compressor was on wheels, and easy to maneuver. I could see the dry wood soaking up the stain and I was happy I'd opted for this method of application. I dreaded the idea of having to brush stain on for hours on end. Once I had the first coat on I let it set for a couple hours while I took a break, then went back out and applied a second coat. This probably would have been sufficient, but I had read that the very best thing to do when applying stain with a sprayer is to go back and brush over the job. Doing this really drove the stain into the wood and allowed it to fill every little pore.
