Also consider whether your batteries will sustain the continuous overnight power drain of a CPAP. You'll be glad you have that solar panel--and you may even want to add another! :-) Most relatively new CPAP machines run on 12v directly and the current consumed is minimal. The manufacturer of the unit I use, will be happy to sell you a 12v power adapter for about $40. I just chopped off the exisitng connecter and used a pair of Anderson Power Pole connecters (which I standarized in my vehicle) so it could be plugged in to house power directly. Cost about a $1 each (x2). My unit draws maximum current only when the blower is running full tilt, but that only happens if you remove the hose and turn it on. uses about 2 amps in that condition. With a load on it, i.e. using the mask, the draw varies based upon my breathing, but is always less than an amp. In other words, the power consumed by a modern CPAP is virtually negligible.-Dave

I don't know how many CPAP users have that type, but that's what I had in mind when I cautioned that power use when boondocking might be an issue--I've been told that it is for some people.Andy Baird http://www.andybaird.com/travels/

It can be. My machine has a heated humidifier, which is powered by AC, but I have not measured how much that consumes, although I doubt it is more than 100 watts or so. There is only about a half-cup of water in it that is warmed only slightly. If I am boondocking somewhere, I just skip heating the water. The machine works just like normal, except the water is not heated. Has not been a big deal for me.-Dave
Re: crock pot and voltage Reply #29 – January 05, 2008, 06:56:13 pm Yahoo Message Number: 87941Judy I have been using a CPAP machine for sleep apnea for 5 years. My present machine is 110 volt which I plug into a small inverter when I don't have campground electric. My previous machine was also 110 volt but also came with a 12 volt adapter. Stan
Re: crock pot and voltage Reply #30 – January 06, 2008, 09:10:11 am Yahoo Message Number: 87950I'm not sure how long it would take to drain your battery if parked, but perhaps while on the move, using a regulation Crock-Pot would work. I have a six-cup sized Crock-Pot that uses just 80 watts when it is running. This will cook a good-sized roast, bake apples, bake potatoes, cook pre-soaked beans, and simmer soup or lentils quite easily. Since there is no temperature control (it is always on "Low"), I usually put the food into it when the food is HOT, having heated (or browned) it beforehand. This seems to be sufficient to keep the food at an occasional boil.Surprisingly, I have had no luck with cooking white rice in this manner. It does brown rice, wild rice, or any mixture of the longer-cooking grains like barley, quite nicely. I guess it does best with things that require a long time to get done, rather than the shorter amount of time for things like white rice.I don't know the wattage draw of a regular Crock-Pot, but I would think it would be safe to use it while the engine is running during a travel day.Virtual hugs,Judie Grounded (temporarily) in - Tucson, Arizona
