Converter, not inverter...

Thanks for all the helpful suggestions and information.
To provide more information, both machines are new...3 months and 1 month each so they are newer models. (We both just starting using them so we have no experience with this trailer issue....) We would definitely not be running the humidifier options on either machine.
We would have to get a converter in order to plug into the cigarette lighter and run on 12v. But those cords are only 7 feet long and the cig outlet is under the dinette in the Escape...pretty far from the head of the bead in the loft.
If we stayed with the standard power we would have to use our inverter and run off the one outlet that is powered by it. They do make battery packs for these CPAP machines but they are quite pricey...we'll just have to think about it...maybe just one machine on the inverter and see how it draws the battery down for one night.

I think I'd try to get 12V routed up to the bed area to use the simplicity of a converter vs inverter and/or dedicated batteries. Also keeps the floor area free of cords in the middle of the night.

Hi: FMLNM... This issue is why I elected to have a dental device rather than the CPAP machine. It's very portable, takes no power except hot water, but some getting used to!!!
As for a kiss goodnite... either way forget it!!! Alf

I use a Phillips Respironics auto CPAP in the trailer. It runs on 12v with an optional cord so I had an outlet installed near the overhead where it resides. I fill the humidifier reservoir but don't turn on the heat.
We mostly have electric hook ups, but have operated it for 4 nights on one trip with a just a portable 50w solar panel and didn't notice any significant low battery condition.

That's great info! Ours are both Phillips Respironics auto cpaps too. Could we just tap into the lights in the loft to get that 12V supply?

Do you remember which 12v cord system you used and where you bought it?

Its a Phillips brand I got at CPAP.com (I've been very happy with their prices & service).
CPAP.com - Shielded DC Cord for PR System One 60 Series Machines
I see there is also a generic one listed for a number of brands.
You may have to send them a copy of your prescription if you want to buy machines or masks from them, but the cord should be a simple transaction.

I'll leave this question to the electrically inclined - we live close so I took our 17 up to ETI and Reace installed the outlet & a couple other things.
I just ordered our 21 with outlets where I needed them.

Thanks. I too have the System 1 60 series machine and that's exactly the cord that I thought I would need for my machine. My husband's machine is a Resmed S9 and requires a more expensive DC cord...but it only pulls 3.7Amps. The System One wants 6.7 amps. Sounds like it could all work out with the correct cords and cabling.
