The ResMed DC Converter for the S9 series CPAP machines is the best way to power your CPAP when you are away from your home, and it works easily with the humidifier! As ResMed's first power converter of this kind, this converter can power both the machine and humidifier from a 12V or 24V power source such as deep cycle marine battery. Not recommended to power your CPAP directly from a car battery, use a deep cycle marine battery instead. 

This converter is compatible with ResMed S9 series machines only.

This product is compatible with the following machines: 

  • ResMed S9 VPAP™ S Bi-level
  • ResMed S9 VPAP™ Auto Bi-level Machine
  • ResMed S9 AutoSet™
  • ResMed S9 Elite™
  • ResMed S9 Escape™

This machine is also compatible with the H5i™ Humidifier and ClimateLine™ Tube.

If you're going to be away from a power source, we recommend a lithium ion CPAP battery with a solar charging panel and an inverter.

This is a must have for a traveler like me I love going camping but taking cpap was always a hassle now its easy run cpap off battery power of the truck works great love it. Scott Sizemore, 02/28/2019
The reviewer that calls this an "empty black box around a wire" does not know of what he speaks, The ResMed CPAP machine runs on 24 V DC. This device is a voltage doubler that permits the CPAP to be used on 12 V DC. ledlighter, 05/02/2018
This is a rip off for a empty black box around a wire. 12 volts DC in to 12 volt DC out with a ResMed propitiatory plug !!!!! What a price for a wire and plugs! Name..., 05/31/2017

I use one of these converters on my ResMed Auto 25 while on our sailboat. It works great. When we travel on the boat (39' sailboat) we are often not with shore power thus it is important to ensure the boats house batteries are fully charged. Cal Holser, 05/13/2014
