External 30 Watt Power Supply S9 Machine

If you're not planning on using the humidifier with your S9 CPAP Machine, this 30-Watt External Power Supply is all you need to keep your S9 Machine running. If you want to run the humidifier, you'll need to purchase the 90-Watt Power Supply for S9, as the 30-Watt power supply sold here doesn't have the required wattage to power both devices.

Your purchase includes four (4) different adapters to plug into the wall outlet to work in the United States and abroad. This power supply is also smaller and lighter than the 90 Watt version used to power both the machine and humidifier.

What's Included:

  • 1 Replacement 30-Watt Power Supply

replacement power supply

Verified purchase | Sep. 13, 2019 | Verified CPAP.com Customer
International power supply to replace my old burnt one. Comes with most of the plugs needed for international travel as well as the US. Also smaller than previous power supply. Works great.

OK

I bought the 30 watt model thinking that it would be smaller and lighter than the 90 watt model. It is a bit smaller and lighter, but not by much.

Fits the bill

Nice lightweight power pack for travel. Wish I had bought it years ago! Adapters for international travel a big plus.

Great Travel Power Supply!

Verified purchase | Aug. 12, 2015 | Verified CPAP.com Customer
I have a ResMed S9 and it's great! I travel for business often so I have an extra mask and hose that I use when I'm on the go. But I go tired of having to unplug power adapter that came with the S9 each time I had to travel. This 30W unit is perfect! I don't take the humidifier when I travel, so this is a great lightweight option that powers the CPAP unit just fine!

Nice for travel

Verified purchase | Jul. 28, 2015 | Verified CPAP.com Customer
What is nice about this is the power supply completely fits in a shoe rather than being this big brick that takes up it's own space in the bag. Works well.

I am glad I purchase this smaller power pack rather than the heavy original one. I was getting tired having to lug my S9 machine whenever I travel.
