My no electricity solution

[jondough]

As you may remember, I was headed off to an island with no electricity and was trying to figure out the best solution considering weight [all travels by small boat] and economics. As most of the solutions seemed to approach $500 and heavy batteries, I finally decided to buy a generator. I purchased a Yamaha 1000W generator. Could not be happier. It is only 27# dry [without gas] and I ran it 12 days on four gallons of gas. The .66 gal gas tank was still over a third full after more than 8 hours a night. The Yamaha has a regulated mode which steps down to a slow speed based on draw, and my AutoBiPap, ran fine at that level, indicating that it was drawing less than 200W. And it is astonishingly quiet! About the sound of a distant small motorboat, I put it behind the woodshead and could hardly hear it in the cabin. I purchased it indirectly off Ebay [search for Yamaha generator] through their phone # as I needed to get some special shipping, but it was the same price each way, midway through the sixes, a lot less than any Honda. I ordered it from Illinois on Friday and it was in Maine on Wednesday. Great service.

Again, it was a great purchase! Be glad to answer any questions.

Did you use the humidifier with that? That seems to be an issue with some of the other "no power" solutions.

If you have a generator that can supply mains power voltage at the energy ratting (in Watts) that both the CPAP unit and humidifer together require, than you can certainly run the humidifier.

A worst case energy scenario for one of the current generation (Resmed S8 etc) CPAP machines run at a high pressure together with a humdifier run "full on" would be a draw that would probably go over 200W, so in the case of the Yamaha generator mentioned above, it would run at a higher speed and use more fuel. However, many users will probably not be running both full pressure and full humidifier.

Older CPAP machines and humidifiers will probably draw more power.

Cheers,

The Yamaha provides pure-sine wave electricity ["better than mains"] so using the humidifier would be fine.
I did not, just took the humidifier and used it as a pass-over which put some moisture in the air.
I should have thought of testing the Yamaha with the humidifier but vacation was disrupted by my wife getting caught in a small gas stove fireball the first night and I fell down some steps on my coccyx the fourth afternoon. We are both recovering.
Still the Maine woods and lakes were gorgeous.
