CPAP on 12V

You need to get the 12v cigar plug cable for your CPAP machine from the supplier. Although most people use their machines at home, the device actually uses about 9 to 10 volts of DC current natively which is converted by the supplied 110 cable when in home use. You don't need to convert your 12v supply to 110v and then back to 12v needlessly. You just waste energy in the process.

In your AS, running just the CPAP, you can usually get two or more nights of battery time from your battery bank after the normal late dinner and pre-sleep reading time light use. Your machine's wattage can be read off the label or supplied to you by the manufacturer; most are quite low.

My AS came with a 12v cigar plug outlet in the bedroom and beside the dinette.

I think that depends on the CPAP machine, actually. Mine doesn't have an external "brick" power supply, the 120v cord connects directly to the pump section via a Sony-style symmetrical 2-conductor connector. Mine's a Resmed S8 Compact, and it says 100-240 VAC, 50-60 hz.

I'd be interested to learn what models have their power supply on an external brick and take DC in like my laptop, they'd be high on my list for the next one.

Check out CPAPSupplyUSA.com. The Aeiomed Everest is a nice small portable and has a battery pack to go with it when traveling to a place without overnight power. DirectHomeMedical.com has a variety of power connectors for CPAP and BiPAP machines.

In your case, a small inverter (under 150 watts) can be had pretty easily and will allow use via the cigar plug outlet.

AEIOMed seems to have ceased production after a factory fire.

It looks like it was a very nice product, I'll check out competitive items.
