Do you know if any of the various CPAP sites out there publish the actual current/power draw of the units. Saying it comes with a 90 watt power supply doesn't mean that's what it actually draws.
Another question I have, is what is the likelihood that I would need a humidifier under the conditions I described above? High humidity and warm temps. It seems that the bulk of the power goes to the humidifier.
Thanks for the suggestion and info.
Posting links on this site is a good way to increase one's warning level. I'll just point out that a number of people I know are running the Respironics DS560 on a Poweradd Pilot Pro 32000 Ahr battery up to two nights with no additional connectors other than what comes with the battery recharger kit. If you have Prime, then you know where to look.
Also, Philips offers a 12 Volt DC Power cord, that directly connects to a cigarette lighter or battery. You could make your own with coax adapter for the machine for next to nothing. 12 Volts, and the machine runs. The machine maximum startup rating is 12 VDC, 6.67 amps. Normal power use is around 1.8-2.0 amps without humidifier or heated hose.
You're floating on tropical oceans. You don't need a humidifier.
