That's the way the S9 comes from ResMed......I have 3 S9s with that cord

There is a valid engineering reason for using a separate transformer.
These little darlings have been know to generate HEAT, which can damage other components.
Often the transformer dies before the warranty is up--separation can save the company MONEY.
And, of course, the stated weight may not include the heavy detachable power cord!

Its also quite handy when you have differing needs. At home I used the 90 Watt power supply, required for the heated hose. On the boat I run directly from 12V so I don't even have a power supply on board. And when travelling I use the smaller, lighter 60 Watt supply.

As far as DH's question, maybe he should learn to read the spec for himself on whatever machine he wants to use. We don't keep a listing of every machine built or sold in the world, I'm not sure why he would expect us too. Learning to read should be Job #1.

I asked if anybody was actually using a CPAP (or separate humidifier), that was not dual-voltage. I would hope that everybody would at least know his (her) own equipment.

Are yours keys getting lonely again.

so the only point in your question was just to see your DunderHead up on the form again, with another useless post... got it.

THE ANSWER to DumberHead's question:
NOBODY has such a machine-- or they are too embarrassed to admit
they use something that old.
I agree that DH's ONLY interest is seeing his name in print,
No matter how many people his BAD ADVICE and STUPIDITY
HARM.

There was a form? I must have missed the form

Truthfully, I've never heard of any CPAP that isn't dual voltage. The one I had in 1999 is dual-voltage, but had no external power brick.

I am aware that that machine was the only one on the market at that time with integrated humidification.

If you had any other CPAP and needed humidification, stand-alone humidifiers were available. They had their own power source. There was a hose going from the CPAP to the humidifier, and another from the humidifier to the mask. Most of those were not dual-voltage.

Also, it's possible that somebody is using a non-standard power brick that is not dual voltage.
