Is anybody using a CPAP machine that is not dual-voltage?

Does anybody live in the U.S., Canada, or any other 110 volt country have a machine that won't work in a 220-volt country without a converter? Conversely, does anybody live in Europe, most of Asia, or any other 220 volt country have a machine that won't work in a 110-volt country without a converter?

I don't believe that such a thing has been made for at least the last fifteen years, but perhaps I'm wrong or perhaps somebody is using a very old machine.

What do you think, and why do you think that would be important to the world? Jim

Are yours keys getting lonely again.

another example of DH stupid.

Resmed and Respironics provide a power supply that caters for 110 to 240 voltages. It's the box between your machine and the wall power socket and it will adjust to whatever voltage it's plugged in to so I'd say you are wrong. I've just received a machine manufactured in the US (which uses 110 volts) which works perfectly with the 240 volt system here in Australia.

Holden, that box does not come automatically with machines - yours must have been ordered specifically by someone who knew you needed the conversion features.

Holden calls the "box" the power supply, AKA the power brick, it is supplied with the machine.

I really don't think any are made (any more) that aren't dual voltage. I would think maybe a very old CPAP machine might not be dual voltage. Also, some of the older stand-alone humidifiers might not be dual voltage.

I'm asking this because every once in a while, somebody asks about needed a converter for travel. It would be nice to be able to give a boiler-plate answer that no CPAP ever-made (or made after 2001) would need a converter.

The "boiler-plate' answer is: "Look on the power supply and see what it says." Any other advice is negligence. Its easy to say that most modern devices handle a range, but there are many exceptions. Even a common device might be shipped with an alternate power supply, its always best to check.

To which I might add the need to adapt the plug configuration. The US standard three prong (if grounded) is definitely not universal. The data tag on the power supply will not, if I am correct, provide that information.

Actually you are incorrect, many machines come with a power supply (glorified Wall Wart) that does just that Cord, Box, lead in wire and plug! No power system in the XPAP. Most are Universal in power ratings, 110 to 220 volt 50 to 60 cycle power.
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.

The "wall wart" is integrated inside my Devillbiss, and all the power info is on the bottom of the blower.

I think that's built into Julie's machine. (internal power supply)

I really don't think.

I fixed your punctuation for you.

you're welcome.

Hello Julie

Mine comes with the external power brick as did my S9 loaner.

It looks similar to this and ranges from 110v to 240v AC power: They are quite common and are also used for laptops plus other electrical devices.

I believe you, but just never saw a machine (before) with the box on the cord like that, so presumed (should really quit doing that) that it was a 'special' of some kind. Nice to know mine's apparently built in, though I'm not planning an overseas trip soon.
