If you go to the trouble of installing the 12V receptacle, make sure it is compatible with the plug for your machine…
There are three sizes…
6-volt cigar lighter receptacle and plug
Receptacle inside diameter: 21.34 - 21.46 mm (median 21.4 mm)
Plug body diameter: 21.08 - 21.23 mm (median 21.155 mm)
12-volt cigar lighter receptacle and plug, size A
Receptacle inside diameter: 20.93 - 21.01 mm (median 20.97 mm)
Plug body diameter: 20.73 - 20.88 mm (median 20.805 mm)
Most often used in American automobiles.
12-volt cigar lighter receptacle and plug, size B
Receptacle inside diameter: 21.41 - 21.51 mm (median 21.455 mm)
Plug body diameter: 21.13 - 21.33 mm (median 21.18 mm)
Most often used in European automobiles, and sometimes as a second socket in American automobiles expressly for DC power connections.

If you look at the converter you will see a terminal strip adjacent, you can pick up the 12v there.The same with grnd.Depending on the setup you may even have blank one for a knife fuse.If the run is over 10ft, use 14gage wire for best results.Prior to installation of the female jack, check it by installing your male.You may have to bend the grnd blade over to keep it intact.
I have been running my respironics CPAP on 12v in the MH for 7-8 years now with no problem. As far as wear on the batteries or converter, it is a lot less than the other 12v stuff running, such as the refrig, interior lights, outside lights, fantastic fan, vent fans, heater. The converter is going to run anyway to keep the batteries chargeed. Just plug the CPAP into the new 12V outlet, and leave it there, shore power or not. If shore power goes of during the night, no problem, just keep sleeping and worry about it in the morning.
