DC Travel CPAP/Battery for One Week Trek

[CardiacProtest]

Note: Solar panels are not likely to work in the Highlands of Scotland so I'm ok with carrying two light batteries and limiting use to 6 hours a night.

What is the best setup (travel CPAP, battery(s), DC adaptor) for a weeklong trek where I use a DC CPAP on a battery each night? There are so many options and no batteries give a good sense of how long they will actually work with a DC adaptor for a particular model. I've seen what look like good Li ion batteries that weigh under 2 pounds, and as I'll be carrying them in my pack, weight is an important factor.

Thanks!

There is a thread describing custom packs used for an ascent of Kilimanjaro:

It would help a lot if you described what your pump is, what pressure you use, and whether you'll be able to charge at all during the trip. A full week will be a challenge - I'm guessing you'll need three packs of the size certified for airline travel.

There's much info in the thread listed in my sig.

My at-home machine is an Airsense 10 Autoset, but for travel I have a Resmed Airstart. For camping with the Airstart, I initially bought a Freedom Travel Battery from cpap.com. At a fixed pressure of 14, I only get about 13 hours, so I recently purchased a Maxoak battery from Amazon. Again at fixed pressure of 14, I get 36 hours.

@CapnLoki I'm getting a travel CPAP that can use DC power, so I haven't decided which one. Something light and cost effective. My pressure is 11cm. Thanks for the link!

@Hopeful50 Which Maxoak? How heavy?
