I call upon the VURD - especially those of you with some electrical/mechanical know-how...
I use a CPAP machine when I sleep. It runs on standard household AC power. I can sleep without it, but I really prefer to have it.
I have a couple of camping trips planned in the next month or so. One of them I know I will not have access to electricity, the other I'm not sure, but not counting on it.
They make and sell a rechargable Lithium Ion battery pack (rechargable via car battery or AC outlet). However, it is $300.
There is a DC adapter (cpap to male cigarrette lighter plug) and direct 12V battery adapter (gator clips to female cigarrette lighter plug) available for $25 each.
Any ideas on how to "create" my own or ideas for another alternative power source that is significantly less than the $300 price tag for the LI ion battery?
I need something that will last me at least a couple of nights (~6 to 8 hours each night). Recharging may be an option during the day, but I don't think I can count on it.
