Here's a topic where the creator built a CPAP power station from 18650 cells.

A lot of good information in there.

This is gold, Jerry! Thanks for fishing it up for me!

I tried a 45 Ah deep cycle 12V battery with the resmed converter, worked all night and charged with my 15 A charger in less than a half hour. I don't think it discharged very deeply. I was running the AS 10 around 10 cm of water pressure, climate line hose, humidifier set to "1". I am going to try t...

Understood. Very grateful to you for explaining that the capacities of these products is referenced to a lithium cell voltage. I was trying to figure out why it weighed so little. I am going to make my own battery. Any idea of the best number and configuration of Samsung 18650 batteries, to achieve ...

Just wondered if anyone has tried the AntiGravity Batteries PS-45? https://www.youtube.com/watch?v=oM0GPV2r4Vg That one would run an Airsense 10 including the humidifier and heated hose all night, at least at my pressure. I can charge it with my 100 W solar panel when I'm up north. I need around 19 ...

If you turn off the humidifier, turn off the heated hose, go into airplane mode and lower the pressure, you *might* make it halfway through the night. I measured the draw of my Airsense 10 at the pressure I use, it is 1.4 A. Two of those batteries in parallel should do the job. The ResMed table siz...

I fought two levels of ResMed tech support and eventually spoke to someone knowledgeable: The 90 Watt DC-DC converter at this link has a dual Voltage input range: https://www.resmed.com/us/dam/documents/products/accessory/air-10-s9-90w-dc-converter/user-guide/air10-s9-dc-converter-90w_user-guide_glo...

Ha! Thanks for pointing that out!

I am going to try connecting the Resmed converter to it.https://www.amazon.ca/gp/product/B0721T ... UTF8&psc=1

I'm hoping the resmed will boost it from 18 to 24, and take care of any interface/protection issues.

Duplicate post. Sorry for my double tap.

Thanks for the pinout electrical details. YOU ARE RISKING YOUR MACHINE AND DEFINITELY YOUR WARRANTY. Understood. A DeWalt battery isn't 24V, right? It's 18. 18*4 = 72Wh No. 20 V, 4 A-h. Would give similar capacity to the Medistrom. https://www.dewalt.com/products/accessories/batteries-and-chargers/b...

This is a12v, 35 Ah battery. That's 420Wh, or almost 5 times. Maybe that gives you some thinking points... The Medistrom 24 V unit seems to be around 4 A-h. As far as I can tell, the Duracell battery you posted could run my Airsense 10 for a week even with the humidifier on, seems oversized. It wou...

Big talk from Americans who are not qualified to vote.

Part of what's wrong with the world is that we're too tolerant of stupid ideas.

Please stop. Good luck in life.

Sorry if it was not clear. Machine is fixed now.

Let's try not to abuse each other okay? There is nothing to be gained by putting others down. I called 4 stores trying to get a repair in Canada, including one in the Toronto area. The one I dealt with is owned by Shoppers Drug Mart, which is a very large company. They all said all repairs are sent ...
