Can be used with the H5i humidifier attached to your machine
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. The best part is you can bring along your humidifier! For the first time, ResMed has designed a power converter that can power both the machine and humidifier from a 12V or 24V power source such as in a car, boat, or other vehicle.
