Here's the problem guys.
You need electricity to run an air compressor.
so now you need to solve that problem.
unless it runs on a 9 Volt battery.
I think that is already included in the $2 price to fill it up. There are many ways to get electricity. There's coal, nuclear, wind, solar, and many other ways of getting it. It's the other things I would like to have explained.
