Was wondering if any one uses these while out camping and any idea of how much power they use ?? I use one (just started recently) but havnt been camping since Ive had it and have no idea how much power it will suck from the battery overnight, As much as a fridge ?? I have no idea. Any help would be appreciated as we are going away for the long weekend and need to set up properly. Do I need an inverter ?? if so what size ?? .................

Hi Kimba,
I have used one 4WD camping for a few years and have had no problems powering it off a 300 watt true RMS inverter powered by a 85 AH AGM battery overnight without a problem. The same battery also runs a 38ltr Engel. I usually drive at least 4 hrs each day. I have a Ranox battery booster and never have battery problems as this is plenty of time to fully charge the battery.
Other relevant factors are what type of CPAP do you have and do you want to use a humidifier with it ?
I have a Resmed S9 Elite and when camping I don't use the humidifier as this greatly increases the current required. This doesn't seem to cause me any problems with dryness of the throat for a week or so away.
You need to have a look at the current requirement of your machine and work out the power required by the inverter to power it.

God luck with the machine.

Ken

Hi Ken, I dont use the dehumidifier at the moment, it has one attached but I have it turned off. Its only a trial machine at the moment and I need to actually purchase one but want one obviously for home and when camping. The one I have is a Phillips 2 grands worth but just checked on one of the website that was mentioned from the search on this site and there was one which was only $600 plus the dehumidifier not sure how much that is extra but reckon I would need it in winter time. Im currently on a diet and trying to drop my weight write down and see if it has any affect on the breathing/snooring at night. Only got really bad since I have put on additional 7kg on top of my over weight already. Put on the extra 7 kg since I stopped smoking last June so now is the time to pull my finger out and lose the weight as well....Will see what the power usage is on a few of them. I dont want some cheap noisy crappy thing I want some thing that is going to last. The one Im using at the moment ramps up and down (if thats the correct term) and adjusts itself to my breathing as well. My oxygen satuartion was under 50% (very bad apparently) Will post the results of the trial when I get home dont remember them exactly.Cheers Steve

Ok , rather than just saying search . I have some real answers . What brand is it ?I have resmed that came with a 12 volt adapter . The amount of amps depends on how much air it is pumping . Using the dehumidifier uses a lot more power . Google resmed battery guide , you might not have a resmed but it will give you some handy info . cheers .

Hi Glen

If you use the "search" function on the forum you will also get some results for resmed :)

The search function in the forum should be every users first port of call – lots of subjects have been covered before. Things change and people have different requirements etc. so no guarantee of success of course but you may find the answer you seek. This was all that was being suggested by J&V. Your advice to use Google (a "search" also I would have thought :) is also good advice though you can get overwhelmed by the information available. One good thing about the forum - more specific "real" information related to outdoors in Oz.

Cheers

http://www.cpapaustralia.com.au/shopping/universal-portable-battery-pack.html

Am I reading the chart wrong, 7 hours or 20 depending on model ?? $600 and only get 7 hours from it, better of buying a jumper start for 1/2 the cost and last longer or a 100amp hour duel batt ?? ............
