Power my Resmed 10 airsense

[Bill johnson]

I have almost every connection to run my CPAP from a battery, but I want to make another one. I bought a powerpack for jumping cars that has a 12 volt connection using a 5mm od and 2.5 mm id. I know I will never find that so I'm looking for bare wires going to a 12 volt inverter that raises the 12 volt to 24 volt with the Resmed 10 connector on it. Has anyone seen one. I don't want to buy a cigarette plug on one end and cut it off if I can find bare wires on that end. I bought a package of barrel plugs I can solder on. Right now I use the lithium power pack to run my portable fridge/freezer. I think it would work great as backup power. I also bought a Dewalt compatible pure sine wave inverter off Amazon for less than 90 dollars. I have four 60/20 volt 9 ah batteries that plug into the inverter that I can run the fridge on and the CPAP. Mine will hold 2 batteries but there is another one that holds 4 Dewalt batteries of any size. If someone plugs in 4 different ah batteries it will watch the voltage and draw from the batteries with the highest voltage. if there is a 9ah and a 2ah battery it will pull off the 9 ah until the voltages are equal and then pull off both or all. It also has auto shutdown if the batteries get low. Let me know if there is anything out there like that, Thanks
