Cpap and camping
I know this subject has been discussed here before but honestly most of this is over my head so I'm looking for a simplistic answer if that's even possible. DW has a Phillips IP22 Cpap. 12v 6.6 a. Use...

Ok, Since it is 12 volt forget the Inverter, use 12 volt direct.. Both the inverter and the power converter (Wall wart or brick) are less than 100% so you loose power converting to/from 120vac.
Now 6.6 amps means 6.6 amp hours per hour. or in an 8 hour night
52.8 amp hours.JUST FOR THE CPAP..... A Group 27 at best has 95 Amp Hours..
You can only safely use about 25,, YOu need more battery
Upgrading to a pair of GC-2 in series gives you 220 amp hours (Give or take about 10) and over 100 usable.. That's more usable battery power LEFT OVER come Morning than you now have in the RV. I highly recommend the upgrade.
