My husband and I carry Shumaker power packs from Walmart. We use a version of this http://www.amazon.com/Schumacher-XP2...T9T08FD8NW8ZFA

It has come in handy for all kinds of things. We always try to think, what all can it be used for. Easily charged while we are sight seeing, for the next couple of nights.

If we have power outages in the house, in the night, we can plug in and sleep as normal.

They last for years, and have been well worth it.

Hummm something tells me if you had lost 2 family members to colon cancer due to never having had a routine colonoscope as part of a check up and another who has won their personal war on colon cancer due to early detection via a routine colonoscopy you might not be rolling your eyes at the prevalence of doctors suggesting folks have a colonoscopy.

Saved me. And the procedure isn't too bad if dying of something besides colon cancer interests you.

No matter how many batteries you have consider solar charging to get them back up to full charge.
Two batteries is good though if you are camping in dark cloudy weather or in heavily forested areas where daily sunlight is sketchy.
Two CPAPs can tax one battery as well.
Here in southern California a solar charger is much more important than the second battery though.
My Respironics system One CPAP draws about half of the current draw listed on the tag while not using the heated humidifier. It will use about 10% of a 100 amp hour battery during the typical night.
The humidifier is just a resistance heater. The higher you turn it up the more current it uses. I have found that I can run my humidifier on 1 while on battery power and it does not blow the fuse, and it does not hit the battery too hard. Usually I just leave the heater off and fill the tank for passive humidification.

I would guess that it is usually due to most Americans being overweight. A little flab around the windpipe collapses when inhaling.
Obesity causes many more problems, but a CPAP can keep us around a little longer. I am grateful for mine!
