ResMed's DC Converter allows you to operate any S9 CPAP/BiLevel Machine (with or without the H5i Heated Humidifier and ClimateLinte tubing) from a 12V or 24V DC Power Source like those found in many cars, boats, trucks and other vehicles. The total length of the cord is approximately 7.5 feet. A DC Adapter Cable, as shown, with "alligator" clips is also included for powering your S9 machine directly to an external battery.
Usage Information: This cord will not work with ResMed Power Station (RPS) II Battery Packs. For the RPS II use DC Cable Part 24961 sold elsewhere on this site. Using a non-ResMed DC cord with your S9 CPAP/BiLevel may damage your machine.
Info for Tech Savvy
With S9 w/humidifier ClimateLine, AGM battery 12V 35Ahr ran 3 minutes. Off? restart 3 min. off. Batt. of course fully charged. Used 2 12V 35Ahr Batts. wired in series to provide 24VDC input.
Perfect Used 6-7 hours for 3 consecutive nights without recharging
Would have lasted another night (turn temp./h. down for longer power usage) Used an Amp meter when first turned on, readings fluctuate drastically from 0.3 amps- 2.3A like cycles pretty fast, No continuous current drain. Variable.
I guess 24V input could handle the quick current cycle. Never tested in my car.
I have a nice little wooden box just under bed to hold all necessary equip. Portable- sort of 45lbs. You know Power Failure you don't sleep well. If House AC off/On like Storm, I go right to battery power for no interruption regardless if AC restored. Total usage approx. 80 hrs. Owned 4 yrs.

The product performs as expected. Now I can go camping with my CPAP. The packaging was great and the communication with cpapEchange was most cordial and professional. Wait time was minimal. Written by dB, 2014-12-19

The power converter is a quality piece of equipment. However, I would make one suggestion and that is: Putting an extra fuseholder in the hot lead of the alligator clips cord that comes with the converter. While there is a 20 Amp fuse in the nose of the male cigarette lighter plug, there is no fuse preventing a problem in the alligator clips cable itself. While a problem occuring in the clips cord would be rare, the extra protection would be extra peace of mind. My husband and I used to be involved in amateur radio and one thing that was always done with our amateur radio equipment was to make sure that our wiring from the battery to the radio equipment was fused both at the battery and at the radio, better to be safe, than sorry.
