I'm talking "converter" not inverter. I want 12volts DC from a 120AC
outlet.
Plug a power cord into a 120 volt AC. Plug the female end into the DC
converter. Wire the converter output leads to a Piper APU plug. Plug it
into the nose socket to supply 12 volts to the system.

That's easy. Get a bigger charger than what you originally were talking
about. Like this one from Sears.
