We have a few limitations - Hypertherm 600 suffers nuisance
cut-outs above 45 Amps. It will also temporarily shut down if the
compressor starts mid-cut. So I let the compressor tank fill, then
shut the pump power off before starting the cut.

I only use my compressor for about 15-30 minutes a day. Right now I'm using
a gasoline generator to run it but I am considering the possibility of using
a belt-driven generator and replacing the AC motor with a 12 VDC motor. For
my purposes it won't matter much if it takes a little longer (lower gear
ratio on the compressor) to fill the tank. I also always manage to find
something to do while compressor is filling the tank anyway. The main
problem I see with a 12 volt compressor is motor life and having to change
the brushes etc.

I also use more human-powered tools than I would if I was connected to the
grid. For example I make custom picture frames and I can either (in most
cases) use a big noisy double-miter saw that uses a lot of power and throws
sawdust all over the place or use a foot-powered chopper that makes hardly
any noise and produces wood chips that I expect will be suitable fuel for
the woodgas generator that I plan to build in the not-to-distant future.

A few people mentioned that cordless tools are ineffecient but hey, it sure
is nice to be able to grab a cordless drill when you only need to drill a
couple of small holes and not have to go start anything up or turn anything
else on.
