ResMed's S9 Series CPAP systems use an external power supply with AC Power Cord. There are two versions of the power supply: a 90W version which is supplied as standard with the system, and a 30W version available as an optional accessory (for use without humidifier).
The 30 Watt Power Supply includes four plug adapters, including adapters for US, Europe, Australia and Great Britain.
The 30 Watt power supply offers less bulk (it's 2.5 inches shorter than the 90W power supply) and less weight (it's about 3/4 the weight of the 90W power supply). It's a great choice for CPAP users traveling without a humidifier.
When using this power supply with a humidified machine the heater plate and tubing need to be turned off so that the unit is working in passover humidifier mode only. Please note that this 30W power supply is not designed to power a ResMed S9 machine with a humidifier. If you're using the S9 H5i heated humidifier, then you need the 90W transformer which came with your device.
Also note that this 30W transformer works with all S9 devices, including the S9 VPAP bilevel devices.
I bought a Medistrom Pilot-12 battery to run my CPAP on the plane. I had to ask questions by email to choose my battery before purchase. The responses were returned quickly and were perfect . My online purchase was delivered very quickly and exactly meets my expectations.

Great service & prices !
I was on a clinical trial in a Montreal Hospital. The trial was nearing the end and it was time to return the trial machine and get my own. I shopped around Montreal and then online and found this site. They had the best prices (I saved around 800$ compared to Montreal prices!) and the service is great! They answered my e-mail very fast and did a follow-up. I am happy I found them.

My initial purchase of a Z1 CPAP in January 2016 was very satisfactory staff interaction -fast, efficient delivery, and great product. This fall I received an error message on the machine and phoned for assistance. Dominique immediately asked me to return the Z1 for examination, and promptly informed me that I would get a Warranty replacement from the manufacturer. He was very professional and helpful, kept me informed, and now I have received a brand new unit. Just excellent service and personal assistance.
