... for the resmed you can buy a complete ready to use 12-24 DC to DC converter either from resmed, or from battery power solutions. BPS converter when I bought it was just over $50. works on the airsense 9 or airsense 10. comes complete with the correct plug.
The Resmed price is very high, but the BPS costs only $68 (Amazon). :) It is certainly more compact and convenient than build-your-own. If I'd seen it, I would have bought it.
BPS products are IMHO very high quality and reasonable prices. they started and continue to focus on cpap battery solutions with many good products.
for anyone looking for adapters, inverters, battery packs for cpaps etc. check them out.
When they first started I bought one of there 250WH (roughly 20AH) lithium ion battery packs. still have it, works great. they also at the time had a 500WH unit. at that time 250WH units could be checked as baggage or carry on for airplanes. Now I notice they no longer offer each, biggest is around 100WH, likely due to certain transportation and shipping restrictions.
The 250WH unit will run my resmed or old remstar unit for many nights if I don't used heated humidifier.
