Inverter for Fans and CPAP?

Help a piano teacher and demo architect out here. My husband and I are often on the road for weeks at a time. We would like to be able to do 2 things. 1. Run a fan in the TT when stopped during the day for my husband's work calls. 2. Be able to boondock in Montana this summer. My husband has a cpap that isn't optional. For his healthy and to keep me out of jail :)

What do you recommend as far as being able to accomplish these two goals? We just bought a new 2015 North Trail NT 26LRSS by Heartland. I'm super excited about the new rig. It's an upgrade from our first one that we got last year. That was a 2008 Passport Ultra Light. It's small enough I can still take it out alone to sheep and wool festivals, but big enough for us to full-time while we build a house next year.

Thanks!
  • Welcome to the forums.

    Start with an energy audit.

    If you plan on boondocking with no shore power then consider adding a solar system.

    As to fans, Fantastic Fan (usually overhead vent) runs on 12V. FF also makes Endless Breeze fans, with 12V cord; these are portable to the length of the cord.


    X2, cords are much cheaper than an inverter. JMO
  • I have also tent camped with my CPAP by using a automotive jump box and a cigarette plug adapter for the unit. You can then make a double ended cigarette plug and plug it into the engine side of the coach or TV to charge when driving.

  • Boondocking & CPAP.

    Yes, run the CPAP & or humidifier directly from any 12 volt outlet directly, no inverter, when shore power is not available.

    I would also suggest a small generator or 100 watt minimum solar install to keep the batteries charged & not let them get below 50% SOC.

    Check your converter & determine if it has a 3-4 stage built in charging system. I doubt it does, but that would be beneficial to maintaining a good charging profile for the batteries in conjunction with shore power or the generator

    I personally run my CPAP from a dedicated 35amp 12 volt AGM battery, so not to use the coach 12 volt system, recharging it as needed.

    If you want an inverter and fan, I have had great results from a little $10 portable box fan from Walmart and a 100W Duracell inverter.
