    Looking to upgrade auxiliary power primarily for camping, specifically running a cpap, and charging devices.

    Eventually I will add light bar, ditch lights, fridge (maybe), all the cool kid toys.

    Trying to learn and figure out energy draw, battery size needed, etc. has got my brain all jammed up. I just want a rechargeable power source (done right) that is reliable and won’t burn my truck to the ground

    Suggestions, thoughts, setups? TIA

    Sounds like the first thing to do is find out the needs of your CPAP. Can you take a look at the specs for volts and watts? Maybe give us the model information and we might be able to find it online. I think most of those are 110v, which can be pretty power hungry. Let us know!

    I have done triple batteries in my truck, as well as run a few different portable power units.

    On my 2006 Taco, I used an . I had to replace the PC1700 a few times as expected but that system worked great for 16 years.

    in 2016 I added a 50W solar panel

    The main load on the battery was an electric blanket on an inverter that kept my wife warm and happy.

    On my 2022 Taco, I'm using the same Odyssey PC1700 and 50W solar panel. But I scrapped the dual battery setup in favor of a lithium jump start battery that offers more versatility.

    I installed three separate auxiliary fuse/relay blocks (engine bay, cab, and taillight) to support power loads in each of those locations. You can find my summary of that setup and links to the details or each here.

    Hope this helps...

    Running a Resmed S9 Elite at 18cm H2O. Their chart says (if I’m reading it right) can draw 0.9 amps @12V DC without humidifier calling for a battery size of 11-13 AH. With humidifier (which I’d like to use draws A LOT) can draw up to 6.59 amps @ 12V DC calling for a battery size of 79 AH

    the sticker on the back of the machine has:
    DC 24V
    1.25A (FG)
    3.75A (SYS)

    I would be sure to use a Resmed DC adapter. I bricked my S8 Escape trying to use an adapter I had for my old Respironics CPAP :anonymous:
    When camping I don't bring my humidifier because as you mentioned it draws a lot of power. I use this heat/moisture exchange thing that helps keep the dryness down. https://www.cpap.com/productpage/heat-moisture-exchange-unit

    I’ve never seen one of these before. Does it stop your nose from drying out? That was always my problem not using the humidifier. Not trying to hijack OPs thread, but really curious.

    It makes a difference vs without anything, but not an equal to humidifier. You can use it for about 5 to 7 straight nights before you need a new one. Totally worth it for weekend camps or traveling.
