Lots of good info in here, thanks for sharing fellas! This turned out to be very timely considering I was just diagoned with sleep apnea today..
What battery cord combo did you use? Trying to weed through the options.Yes, I've used the Air Mini at 2 different camps at 9,960 and 10,300. No problems other than condensation if in an unheated tent. Ive had to take my shirt and wipe out my mask once or twice during the night.
Yes, 10,400’. No problems with effectiveness, but thinner air consumes more batteryAfter researching several of the travel size CPAP machines, they are all rated for a maximum altitude of 8,000-8,500 feet. Has anyone used one of these above 10,000?
The Air Mini comes with several cords that are all kind of proprietary or made to fit the Medistrom battery. The cord to connect them is about 12".What battery cord combo did you use? Trying to weed through the options.
I just started using an airmini. I also have a Sherpa 50 with inverter. DO you think there is any difference between 1) plugging the AC adapter into the inverter and 2) using a dedicated adapter with 12V cigarette lighter type input and getting a cable to connect the Sherpa directly to the Cpap unit like this one https://www.cpapdirect.com/parts-an...om-airmini-output-cable-for-pilot-24-battery?There are few threads, one I contibuted with a lot of info you can search on. My summary:
I backpack hunt and have severe apnea. I use HSM z1 auto pap. It is one pound. It auto senses altitude pressure changes automatically. It works great and use all the time for overnights local business travel too.
I have 3 goal zero Sherpa 50 battery packs. Each wis one pound, but I don’t necessarily take all of them. At 70 degrees I can get 15-16 hours from one. At 34 degrees it’s about 8 hours. I also have a goal zero trifold nomad 20 watt solar charger. In my back yard and tending it will fully charge a Sherpa 50 in 4 hours on a sunny day. In real mountain conditions mixed light it’s an all day process to get it mostly charged. So you may loosed a day of hunting. It’s 1.5 pounds.
I’ve migrated to a base camp and spike out 1-3 nights cause just easier for me to take one or two Sherpa 50. By using a sticky toe warmer on each side when cold I can get battery life up to 10 hours each. Hunting, two 5 hour nights is reasonable so one unit.
The pain about my equipment is I plug a female 12v batter adapter in it and then a 12v male end to the cpap. Seamlessly works but a lot of wires. Newer technology is a usb power, but then you need a battery source that has the higher usb. None on the market that I’ve tested work more than a hour or two despite their claims. Goal zero has discontinued the Sherpa 50 and a new design Sherpa 100 or 150 cant remember has twice the power and a high power usb. Very pricey but that would be my next purchase along with a new hdm with the usb power cord.
Appreciate dentist honesty. Be sure you absolutely know your degree of apnea. Those dental devices are very expensive and have been studied well in mild apnea, causally in moderate. None I’m aware of in severe apnea. My recall in moderate is 25% success measured subjectively in post sleep from patient. Not medically monitored. Would not risk my life and multiple thousands of dollars if you have severe apnea.
If apnea, there is a price to pay to stay safe if you go into backcountry hinting in weight and expense. I for one want to go high and kill stuff.
Yes, converting dc to ac gives up battery run time capacity. I believe goal zero can accurately confirm, but it’s 25% loss or more.I just started using an airmini.

THanks in aadvance for your opinion
Thanks, they did confirm power loss and said there is power loss in using the resmed 12V adapter (12 to 24) as well though less. I think I will try with inverter first and then consider getting the resmed adapter depending on how many hours usage I getYes, converting dc to ac gives up battery run time capacity.

Thanks for the thread bump some good info in here, and "hi" from McCall. Your packers look fun, use them around here?Pretty sure I'm about to get a sleep apnea or similar diagnosis. Appreciate all the info on here. I've got a humless 200 battery pack already, but might need to look into solar panel to use as well.
Luckily I have some help packing in gear.

A year later and this still looks like the simplest solution. ThanksHere is a picture with a checkbook included for size reference. I dont run the Air Mini hose or mask. The hose is also proprietary in size thus the adaptor sticking out.
Surgery last year so no hunting situations. Scouted two weeks ago +11,000 ft and < 40 degrees.Got a new CPAP recently and discussed backpack options with the setup provider. He suggested https://www.amazon.com/dp/B0791Y1WSQ?ref=ppx_yo2ov_dt_b_product_details&th=1
AIMTOM 42000mAh 155Wh Power Station
Charged it a month ago and let it sit and then used it the last 3 days with my older Resmed S9 for 3 full nights, 7.5 hours avg. per night. 6,300+/- elevation, Castle Rock, Colorado. It is August so it's warm, 68 to 65 degrees in house. Bought the DC cable (lighter plug in adapter) as suggested. No heated water and no heated tubing. Pressure setting is 11 ish. It's about 3.5 lbs. plus a few oz. for the dc adapter, plus the Resmed S9. I paid about $137, today it is $115. Seems most one night batteries are $300+. I'm happy with the purchase and should get 2 to 3 nights (4 to 5 days) in higher altitude, a bit colder for September Archery. I've been tied to the Honda EU2000i until now so ready to fill up the Kifaru 44 mag and get with it.
