I have the same issue i take breaks in my caravan where we are always off grid with a huge battery and solar pv , i am currently building a dedicated psu for the 24v machine ,the plug has three components though it looks like a standard coaxial power plug it has ground on the outer +24v on the inside wall and 3.2 volts on the pin in the center.incidentally our local hospital whom supplied the machine was informed we had accidentally left our power supply in Greece on a recent holiday so they happily supplied a replacement to which i scavenged the necessary plug from !. i have got a 10 amp 12 volt dc to 24 volt inverter and built a small circuit to make the 3.2 volt output so now i have a complete power supply built on the bench however i have not yet tested it over any amount of serious service time as i am still waiting for one part to arrive to complete the build ,if this one works satisfactorily i will have to build another one as both me and my wife have the same complaint and purchasing a battery pack is beyond our means.
Hi my name is Shawn ,i have recently been diagnosed with severe sleep apnea as has my wife a couple of months ago .I am about to go to consultants this week and have it all explained to me and possibly have a machine set up prescribed to me too, i am 52 and have suffered for a very long time from irrational tiredness so it has become a way of life for me and up till now had blamed it on my Diabetes (type1) so i am on a new journey hopefully it will be a good one because i am done with bad health and sleep !.
