Yes, you are right D.H.. Thank God that AC is usually available everywhere, and modern CPAPs will work just as well as laptop computers everywhere in the world without any trouble at all.

My thinking about DC power inverter capability is for the situation where there is a power failure for a prolonged period of time (e.g. if there was a hurricane, earthquake, ice-storm etc.). As we all know, situations like Katrina or the tsunamis in Asia occur more and more frequently these days due to global warming.

Of course CPAP users will be in trouble. They will need to rely upon DC power in the form of marine or RV type batteries, car batteries or else gasoline generators.

If CPAPs had DC capability, users could outlast a brief power outage by plugging the unit into the cigarette lighter of their car. Perhaps the CPAP industry could sell long-long cords of about twenty metres so that the user could run the cord out the bedroom window and into the car.

If the CPAPs could run on DC, the user would not have to worry about putting an inverter between the power source and the CPAP. Some generators come equiped with pure sine wave inverter technology, but there are few models like that. Solar power can be used to charge a dry cell, but again DC power would be required. I have read an account of one guy who went on a camping trip using solar power. He said that solar power worked just fine to charge the car battery and run his CPAP.
