I also found this on a South African info site: Tourists to South Africa should be aware that: The South African electricity supply is 220/230 volts AC 50 HZ. Most plugs are 15 amp 3-prong or 5 amp 2-prong, with round pins. If an adaptor is called for, consider bringing one with you, although they c...

It says: AC 100-240V 50-60Hz DC +24V 3.75A Does that mean it has it's own transformer and a socket adaptor will be enough to protect it. We'll plan to buy a local surge protector in any case. I'd take one but then we'd be back in the same continuous use problem. Thanks so much for your help.

It is a ResMed Series 9. I will go check the machine again for the other info from the plug.

Well, that didn't seem to work. Can you tell me how to post an image?

Thank you. You are very kind to take this much trouble. And since you are, perhaps should be a bit more specific. We will be in Cape Town, South Africa where the current is between 220 and 240. I don't know if SA has alternating or direct current. Here are the pix I was able to take of his 2-part CP...

Thank you for your reply. Not sure my feeble brain understood a word past "look on the back of the machine". But I've asked ResMed the same question and I'll pass on your and their reply to my husband. I'm hoping he'll be able to understand it and take appropriate corrective measures. Thanks again!

My husband relies on a standard CPAP equipped for American 110 volt current. We will be staying in a 220 volt country for 3-4 months. I have gotten the appropriate socket converters and current transformers. However, each transformer I found had the warning that it was for intermittent use and conti...

OK. One more attempt to clarify it from my perspective. If people get it, they get it. If they don't, they don't. I can get to sleep just fine and I can return to sleep when I wake up to pee or just because. My sense is that I sleep just fine and I cope with my days without feeling unduly tired. I w...
