Netherlands & C-Pap use

No converter needed. CPAP’s will work fine as electronics these days will automatically convert. All you need is a standard Euro plug adapter.

I concur with Jay - all you need is an adaptor. Have a great trip!!!

Do not worry. C/PAPs are dual voltage, just a european plug adaptor as for all electronic devices.

Thank you for quick responses. So does that also apply to charging cells.phones, etc., just need the adaptor?

I leave my CPAP at home. In many cases, skipping the CPAP for a week is not a life threatening event.

But I do get tired of my wife poking me in the ribs in the middle of the night telling me to rollover.

That might be true, but you need to double check that your machine is multivoltage. Otherwise, you might get some unexpected fireworks. If it says 110-240V on it you're fine and you just need an adaptor.

Yes, my CPAP, and most modern electonics like phones and tablets, are multi or dual voltage and just need a simple plug adapter. Do check for the label on the CPAP about voltage.

So does that also apply to charging cells.phones, etc., just need the adaptor?

Yes, I haven't brought a converter to Europe in over a decade - just about everything is dual voltage. And keep in mind that USB connections are universal, so you can just plug some devices directly into a USB port without an adaptor.
