Using a C- Pap

[SkiSmuggs]

I use a CPAP and tried a large jump start battery with 300 Watt inverter when dry camping 4 days last year. Left it at the Ranger station every morning and it didn't get enough charge to last the next 3 nights. So you need direct 12 volt. Most cpap devices will run 12v so order the cable from CPAP. Com or such. If you have a single 12v in your RV, suggest separate 35 amp deep cycle or convert to twin 6 volt like I am doing now. I was okay with just CPAP, but add a fan for cooling and it gets marginal. I also got a 100 Watt portable solar unit as I want to dry camp more.

The website at the following link should have info on your CPAP machine and whether it can run on ac and 12v with the right accessory.

Wow. Thanks for all the help. I went to Harbor Freight and bought one of the 5 in 1 portable power packs. My wife used it and it works fine.
