After reading this thread, still not sure got a definitive answer?

I read the CX website (thanks Christep) and also talked with manufacturer (Resmed) re the 115v, 400H power that CX supplies - they said my cpap unit would work properly. And they also just emailed me a document that says the unit meets FAA requirements.

Just wanted to double-check if anyone has actually used it on-board, and what their experiences have been? I normally do the JFK/HK route in business class and sleep for around 5-7 hrs.

FWIW - no flame intended to anyone, but the cpap machine is extremely quiet, passengers sitting next to you wouldn't even know it's on, and certainly quieter than my snoring
