All she needs for that is a 12-volt deep-cycle battery and the 12 volt Respironics cord that you can purchase online, as described in this post.
The old REMstars have a separate input power jack for 12 volt power. They can be operated with 12-volt power directly without the need for a transformer or power inverter. The transformer is built into the machine itself, which is one of the reasons I call my old REMstar Pro "The Tank" - it's huge, heavy and built like a tank.
i've been framed by the dust bunnies. the little hole directly above the 120v plug hole was stuffed with dust so bad that it looked like insulation so i never thought it could be a place to plug in a transformer. a blast of air in the hole changed my thinking. plugging a 12v source into it proved you are right. i've had this thing since 2001 so in the beginning i may have known that was a power hole and forgot. sorry for any confusion, folks.
I've finally done it. the first documented case ever of me being wrong, in this thread at least.
