Now I remember why I'm on CPAP therapy. I was dead tired after two days of cycling and didn't sleep well due to a combo of cold and no CPAP. I will need to look at battery / travel options for those rare times when 120V power is not available for my S9.
Needless to say, last night was a much better sleep (back at home with power for my CPAP).
Soooo....anyone have any ideas about a easy / light way to do CPAP for a day, maybe two, when power is not available?
