ok guys and gals I need some advise, I have a 2018 3920, in my 3920 I have 2 deep cycle batteries from CW. I was looking at a portable battery unit for my cpap but that is turning out to be more a chore then what its worth.

Im looking at when I travel sometimes I spend the night at rest stops and instead of firing up the generator/inverter to run my cpap at night I wanted to get a battery but my CPAP requires 6.67 amp at 12 v DC. The portable battery units only supply 5 amps.

so questions is would the rig be able to power the CPAP through the night using the 12v DC connector behind the TV without totally draining the batteries or ruining them? Would the batteries charge during the day while I drive hooked up to my truck and I'm sure they would charge when im plunged into shore power.

Thanks !!
