Cpap

Is your CPAP dual voltage? Does it say 110v or does it give a range 110-220/240v? If its not dual voltage, then you'll fry the thing if you plug it into a European socket.

Using a electrical adaptor will not work? It is a 110 voltage.

One with a rechargeable battery may be the better solution than getting a voltage converter so you could use the one you have. What you have requires a converter not just a plug adapter.

Coach,

Just to confirm, did you check the Input Voltage specifications on the CPAP power supply? Also, what brand of CPAP machine is it? If you could provide information on these questions, it may be possible to find a solution.

If your present power supply is only designed for operation on 115 VAC electrical systems, it could be used with a transformer voltage converter, however that's not an ideal solution as transformers are inherently heavy and awkward to travel with.

Travelling with a rechargeable battery is also not ideal, as that battery will have to be recharged and it's also going to be large, awkward and heavy to travel with. You'd have to ensure that the battery is capable of operating the device for a full night. Having to recharge the battery on days when you're changing hotels / locations would be a real nuisance.

Most electrical devices these days are manufactured with dual voltage capability. In the US, we use 110 volts which is delivered at 60 cycles of AC current, or 60Hz. In Europe, the voltage is 220 to 240 volts, delivered at 50Hz.

Near the plug, or on the bottom of your CPAP machine will be a sticker with VERY small writing. This will indicate the voltage and the cycles. As I say, most devices will show 110 --240 volts, 50 --60Hz. If yours isn't so marked, you will need to use a transformer which, has been mentioned, is very bulky and heavy.

If you have doubts, go on Amazon.com and find your CPAP unit for sale. Check the specs, and it will tell you if it is dual voltage or not. If it is, then all you need is an adapter for Italy, available for very little money in the RS store.

Edited to add: If you can't find the voltage tag, it's probably better to contact the vendor or manufacturer from whom you purchased the unit to determine the input voltage requirements. Amazon doesn't have everything on its site.

I have a Resmed Airsense 10 and its dual voltage - would be extremely surprised if yours weren't. Worked perfectly fine in Paris, Prague and Rome with a type E/F plug adapter

I also have a Resmed Airsense 10, your response is helpful. For portability I was looking at the travel cpap Resmed offers. Appreciate the response and relaying your experience with your machine.

Coach,

The *Resmed CPAP machines should be provided with a multi-voltage power supply. You can verify that by checking the label on the power supply.

Thanks.. appreciate the responses

Check your Resmed Airsense 10 manual looking specifically at the specification section. Does it look like the following:
