Overview
This is ResMed's own mains power cord, the one its catalogue lists for the S9 series in North America. It suits anyone whose cord has gone missing in a move, frayed at the plug, or stayed behind in a hotel room, and anyone who wants a spare.
Fitting it takes a few seconds and no tools. One end has a rounded figure-eight socket that pushes into your power supply, and the other end is a flat two-prong plug for a standard Canadian outlet, with nothing to set up or adjust afterwards.
Key features:
- Made by ResMed: Listed in ResMed's own catalogue as part 36830, the S9 power cord for North American outlets, rather than a generic copy.
- Easy to match: The figure-eight end matches any power supply with that two-slot socket, so you can confirm the fit at a glance.
- Reaches the outlet: Long enough to run from a wall socket behind the nightstand up to a machine sitting on top of it.
- Standard Canadian plug: A flat two-prong plug fits ordinary household outlets across Canada and the United States without an adapter.
- Cord on its own: Sold without a power supply, so a supply that still works stays in service and only the worn part gets replaced.
If your old cord is lost, damaged or packed away for travel, this gets your machine running again without replacing the power supply. Check that your supply has the figure-eight socket, and you'll know it's the right cord before it arrives.
How it works
Connecting it
Push the figure-eight end firmly into the socket on your power supply, then plug the two-prong end into the wall. Use an outlet that isn't controlled by a light switch, so the power can't be turned off by mistake overnight.
Routing the cord
Run the cord where nobody will trip on it, and keep it away from heaters and anything hot. Make sure there's no strain on either end, so the plug and socket stay seated.
Looking after it
Check the cord and both ends now and then. Replace it once you see split insulation, a bent prong, or an end that no longer sits snugly. Never put the cord in water.

Features and use
Where the cord connects
On ResMed's S9, AirSense 10 and AirSense 11, this cord never touches the machine itself. It runs from the wall outlet to the separate power supply, and the power supply's own cable feeds the machine.
- Sold as the cord alone, with no power supply
- Philips DreamStations share this layout, though Philips asks for its own cord
Checking your power supply
Look at the socket where the cord enters your power supply. ResMed's supplies are double insulated, which is why they need only two pins and no ground, and the matching socket is the rounded figure-eight.
- Figure-eight, two slots: this cord fits
- Three slots, like a kettle lead: you need a different cord
Travelling outside Canada
ResMed's power supplies accept household current from 100 to 240 volts, so the supply copes with power abroad. The cord is a different matter, since its plug only fits North American sockets.
- ResMed advises carrying a cord suited to the region you're visiting
- A plug adapter is the usual fix for a short trip
Signs a cord needs replacing
No manufacturer sets a schedule for power cords, so condition is the guide. ResMed and Philips both tell you to inspect the cord and plug regularly and stop using one that shows damage or wear.
- Keep it clear of heaters and hot surfaces
- Route it where nobody will trip over it
- Never let it sit in water or get soaked
ResMed part
ResMed's catalogue lists this exact cord for its S9 series in North America. Replacing a lost or worn one brings you back to the original part, not a hardware-store lookalike.
Figure-eight end
The connector is a figure-eight, a standard shape you can recognise at a glance. One look at your power brick tells you whether it takes this cord, so there's no guesswork at checkout.
Bedside reach
It runs comfortably from a wall outlet behind the nightstand up to the machine on top. That keeps an extension cord, and the clutter that comes with it, out of your setup.
Flat plug
The wall end is a slim two-prong plug that suits a standard Canadian outlet. Your power supply handles the electrical conversion, so the cord's job stays simple.
Common questions
Which CPAP machines does this power cord fit?
ResMed catalogues it as the North American cord for its S9 series. For any other machine, check the socket on your power supply: if it has the rounded two-slot figure-eight shape, this cord fits it. If you're not sure, send us a photo and we'll check for you.
Does the power cord plug into my CPAP machine?
Not on most current machines. ResMed's guides for the S9, AirSense 10 and AirSense 11 all show the cord running from the wall to the separate power supply. The power supply's own cable is the one that goes into the machine.
Is the power supply included with this cord?
No, this is the cord on its own. If your power supply itself has stopped working, a new cord won't fix it, so check whether the supply's light comes on with a cord you know is good.
Will it work with my Philips DreamStation?
Philips' manuals say to use only power cords supplied by Philips Respironics, warning that others may cause overheating or damage. For a DreamStation, we'd follow that advice and use the cord Philips makes for it.
Can I use this cord when I travel abroad?
Only where the sockets take a North American two-prong plug. ResMed's power supplies handle 100 to 240 volts, but ResMed advises bringing a power cord suited to the region, so pack a plug adapter or a local cord.
How do I know when to replace my power cord?
There's no set schedule. ResMed's guides say to check the cord and plug regularly and to stop using them if they're damaged or worn. Replace it if you notice damage anywhere along its length or a loose fit at either end.
