I've been on CPAP for years and run mine on 12V in the RV. Mine's a Puritan Bennett GoodNight 420 (12V in) that claims to draw 1.5A max - varies based on pressure setting. Mine draws much less than that, and I've run it for 3 nights on a Schumacher PP2200 22ah, 400W portable power pack (tent camping). Of course, this is NOT using the humidifier heater, which draws considerably more amperage.
