Appreciate the input. After the 1st several replies it became VERY clear that a bottle of pressurized air was not what I needed. What I wanted was to be able to refill a 1-pound (empty) propane tank with air and be able to get as much gas vapor out of it as an original cylinder. The key is that in the original tank the propane is filled at a very high pressure to the point where it is not a gas anymore but a liquid. As the valve is cracked open and a small amount released it quickly warms and expands greatly in volume (remember "PIV-NERT" LOL). Anyway this is why you can run a propane tank for hours & hours before they are empty. Since I have no means to pressurize a tank with liquid air I have moved on. I just bought myself an inexpensive 5VDC pump and 5VDC Lithium battery pack and mounted it to my 2 gallon sprayer. It works like a dream, all for about $25. I can fill the tank 3-4 times off one charge and the pressure is just fine. I made a wide strap that slings over my head on my right shoulder opposite the tank that hangs off my left side. This way both hands are free and thus far my back can handle it. TU everyone for a wonderful discussion.....I have put this dilema to rest.Why reinvent the wheel. This is just one option and there are many sizes, brands and designs to choose from and if needed you can install a longer hose. If you don.t want to install it on an atv or tractor you can use lawn cart for it or even a kids wagon. If you did manage to find a way to make the 1lb propane tank work, you wouldn't get much spraying done before losing pressure and would be constantly changing out cylinders. You would be better off staying with a handheld pump up sprayer
