I've just finished screwing about with this myself.  Basically, I took out
the circuit breaker and replaced it with a GFCI socket (with a power on
light), and wired up a 220W inverter in that hidden area going to a switched
socket - I now have 2 GFCI sockets plugged into the 110V line, and above
that a single 110V socket that I turn on when I need it.  I also extended
the power warning light from the inverter so it sits in a little hole I
drilled in the socket front cover, so I know the inverter's running.  I
figure it's enough to charge a laptop, or the camera battery.  I don't want
to run a hairdryer or anything similarly crazy, so it works out just fine
for me :o)
