CPAP for multi day trips

I’m looking for info on your experiences with a CPAP machine on multi day trips.

I am planning a Deso trip for April with my dad who uses a CPAP.

What brands, models, batteries and charging methods work best?Packability efficiency is also a bit of a concern.

Thanks!

I use an old Philips Respronics CPAP I got at a garage sale on off the grid trips. I don't use my nice new machine where damage can be done. Whatever machine you use make sure its 12v that way you don't have to invert power to 120v, Inverters are very inefficient. Most of the consideration goes into the battery. I use a knock off 12v Milwaukee cordless tool batteries the BIGEST ones u can get like 9AH(helps make it through the night). Then you get the 12v adapter not the Milwaukee one but the one that has wires sticking out and is 3D printed by some guy in his basement (The reason for that is the factory adapters will not allow you to draw enough power to run you machine) take those two wires and put a cigarette charging port on it or whatever 12v connector goes to your machine(make sure to pay attention to polarity sometimes it matters) Plug it in to your machine and do some test runs to see how long your machine will run on one battery. the advantages to this setup are the batteries are inexpensive for the AH, setup is SUPER light, Very compact, Lithium batteries will take a deep discharge, versatility of batteries and cost. CPAP machines are VERY voltage sensitive(both over and under) so if you try to use a Lead acid battery you will only get about 2/3 of the juice out of it before the voltage drops and you machine will shut off so avoid them at all cost. 6 batteries, a 12v adapter and a cigarette plug is about 200$. Make sure to do some test runs every machine is different. Matt

I forgot to mention. I use a cigarette lighter attachment because it has fuses and with batteries sometimes you need them. Pack extra fuses
