Is there any reason a driver with a jump starter power station could not use an inexpensive (read modified sign wave) inverter to keep a jump starter topped off. Mostly I need to know to use this to power a CPAP. I know this will use more power than a straight cable, but the indicator lights work with AC Thanks

it should work as long as the wattage of the jump box is less than the normal output of the inverter. Also, make sure you are running the engine when using the inverter as it will drain your chassis battery.
