17' Series Sleep App Machines when free Camping

[23chris]

Hello all happy to share we have just upgraded from a eagle to a 17.56-2 OB very happy with the move up no more long setup times in the rain


how ever looking at ideas and thoughts if there is others that need sleep App units while free camping if they have then ran on 12v direct all run through a inverter?


thanks in advance Chris

i killed a inverter 150w pure signwave with a resmed S9 so brought a proper 12v for it.
Sorry cannot remember the voltage drop I run with a humidifier normally, only used it over nights so not been worried about power the next day as leaving..
I think a couple of bad days sun wise it would hurt you, I know people who setup a seperate battery for there CPAP. Which is something I am thinking of if we free camp more.

I got mine from here $119.. Our old 17.58 I used the S9 from the 12v and left the 240v power supply at home. Need to wire in a 12v on the 22.68 near bed and will do the same.

My wife is a nurse she said you really should run the humidifier all the time as better for you.
Yes if trying to save battery power I think I wouldn't although we have not been free camping only over night stops on 12v

Resmed has current draw on the below.. so 12's your looking at 13 no humidfier and 54 with one. Hence I said a couple of cloudy days you might struggle on one 100 AMP battery,
