20V PD USB-C Power Supply for ResMed AirSense 11 Air 11 Airmini 65W 20W ResMed CPAP Charger DC Coverter Cable

An usb-c adapter for the Airsense 11 to work with a power banks or charger: https://www.amazon.com/Supply-AirSense-Airmini-Charger-Coverter/dp/B0BV1J88GV

There's actually a USB C adapter that will run off a standard power bank. https://a.co/d/03y7dsGH It will probably drain quickly so get a high capacity bank though.

I purchased an EcoFlow River 3 Plus for battery backup, then a DC output cable, as that uses less battery than the AC cable. A few months later due to backpacking, I bought the Resmed AirMini, a 40,000 mah 65 w power bank and a USBC power supply for the Resmed 11. Returned the AirMini because it made too much noise, even with the baffle. I kept the power bank and the cord, and I get 2 nights with it and it still is charges 35%. Power banks are much cheaper than battery backups. This is a link to the cord, which is the part that's harder to find. https://www.amazon.com/dp/B0BV1J88GV?ref=ppx_yo2ov_dt_b_fed_asin_titleI just use this and the power bank for camping, and keep the EcoFlow at home, so I can use it for the CPAP and other things if the power goes out.

This is correct. What is even worse is that the battery will waste power putting out AC but your CPAP will waste more convertring it back into DC. While you can get 12volt car adapters its better to get a USBC-PD adapter. Something like https://www.amazon.com/Supply-AirSense-Airmini-Charger-Coverter/dp/B0BV1J88GV/ Just make sure whatever battery you choose has USBC-PD support and at the voltage the adapter wants. The one I linked is 20V. USBC-PD can negotiate the voltage so it's a bit on you to make sure you get source and consumer similar. Mismatched voltage wont happen as its part of the protocol but you can find some devices wont run as they require more power than is available. Think trying to charge a laptop with a cellphone charger. Personally I have a Anker Solix C200 that can run my resmed mini for about 5nights before it needs a recharge. I know it can run the Airsense 11 but I haven't tested how many nights I can get with it. https://www.amazon.com/Anker-Portable-Generator-Traveling-Emergencies/dp/B0D62P85ZR/

Here's another one that works officially for Air sense. https://a.co/d/06ka4cEP

Here it is: https://a.co/d/07U9pacX

I got both the battery and Air Mini power connector from Amazon. https://a.co/d/0bMY10R7 https://a.co/d/06FZc2Us

Yup. USB-C airmini power adapter. Pair it with any good quality 100wh battery that outputs at least 20V usb PD at 65w and you should be good for 2 nights. Need more nights? bring more batteries. Solar might make more sense if you reach the >1 week mark. (note: There was a few generations of Anker batteries that didn't work for CPAPs for some reason. That was an Anker problem, not an adapter problem) I also use a 4ft tube slimtube with the hose adapter so I can use standard tubing and cheaper generic heat moisture exchangers so I don't need to use humidx pucks for containment i keep it all in a stuff sack inside of a ziplock for waterproofness. I also made a beer-coozie type container for my air mini unit made of reflectix bubblewrap. But I did that because I went bikepacking and I wanted to protect it from vibration. I don't think it matters for backpacking. Battery life for USB-batteries is temp dependent, so when it's cold you should keep the battery in your bag with you or I tried putting it in my coozie. I think it worked ok. Turn off bluetooth too. I don't know how much power it wastes, but it wastes power. Disconnect the power adapter unit when not using it. There is a small parasitic draw from the adapter at all times because it is converting 20v to 24v. I believe my setup weighed in the 4lb range all told. It's not ultra-light but also not totally prohibitive.

This was a post I made from hammock camping a few days ago. https://www.reddit.com/r/hammockcamping/comments/1tpbga1/comment/oo7t5um/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button I use a Resmed Air Mini, with a battery that costs 60 bucks and lasts two nights, and a converter. If I'm canoeing, I take a solar panel that charges the battery. When I'm hiking, I just take more than one battery if I'm out for more than 2 nights. The Air Mini uses a waterless humidification system called HumidX. If you're in the desert you'll want the Humid X Plus, otherwise, the Humid X works great. Someone on r/ultralight put me onto the battery and converter a few years ago, and it's so much cheaper and works better than the more expensive batteries I've tried, and it's not prohibitively expensive to replace the battery if something goes wrong. I was updating my lighterpack and just reweighed the cpap. cpap - 300 grams converter - 87 grams battery - 391 grams (each battery is 2 nights/25,000 mah) mask, tubing, humid X puck, dyneema bag - 130 grams

I have used my air sense 11 cpap on an airplane with the following hardware. Works great. FLGAN 20V PD USB-C Power Supply https://www.amazon.com/dp/B0BV1J88GV?ref=ppx_pop_mob_ap_share Anker Laptop Power Bank https://www.amazon.com/dp/B0DCBB2YTR?ref=ppx_pop_mob_ap_share

Hammocks and Cpap? This is my jam! I use a Resmed Air Mini, with a battery that costs 60 bucks and lasts two nights, and a converter. If I'm canoeing, I take a solar panel that charges the battery. When I'm hiking, I just take more than one battery if I'm out for more than 2 nights. The Air Mini uses a waterless humidification system called HumidX. If you're in the desert you'll want the Humid X Plus, otherwise, the Humid X works great. Someone on r/ultralight put me onto the battery and converter a few years ago, and it's so much cheaper and works better than the more expensive batteries I've tried, and it's not prohibitively expensive to replace the battery if something goes wrong. Now for the mechanics of using it! I prefer keeping the cpap in a well supported peak loft, so everything is out of the way except for the mask. In summer, the cpap, mask, and battery. sits in my peak loft in the hellbender hammock or in a pocket in my townsend bridge hammock. The Dutchware peak loft is best in class, and holds the weight extremely well. I keep it all in a small dyneema bag, or if canoe camping, inside a real dry bag surrounded by clothing to cushion it. In winter, I keep the cpap battery in my Dutchware perfect pouch, which is between my base and mid layer when I'm not sleeping to keep the battery operational. So I'm not breathing extremely cold air, I keep the cpap under the top quilt once it's bedtime. It's extremely important not to eat meals which will give you bad gas while doing this Cpap repairs: I have done trail repairs on the tubing which had a small leak. I used some leukotape I had wrapped around my miniBic lighter, and the cpap pressure was restored. Now I keep an igneus repair kit which has gorilla tape which probably would have worked even better. When I started camping with a cpap, I hung my entire giant machine from home in a gear hammock next to my normal hammock and used a 7 pound battery. It wasn't pretty but it was doable, just not fun to backpack with. I'm much happier with my current setup. If you have a warbonnet XLC, the shelf should work great as a place to keep a travel cpap and battery. It should be a great solution!
