Not sure where to post this, so I'll start here.
I have to get a CPAP machine for sleep apnea, was wondering if anyone else has one and what to expect running it off the batteries when dry camping.
Wont be a problem when at a campground or on the generator, but I do allot of camping where I can't run a generator at night.
I have been told they all run with a DC to AC adapter that has to be ordered extra. Someone said the make a DC one that can be operated off AC also. Just would like some input before I get a machine.
Thanks
Dan

Hi Dan,

Check out this thread. (//heartlandowners.org/showthread.php/9810-CPAP-Requirements?highlight=cpap) This was discussed a while back, hope it helps.

I will be moving the thread to a different area also.

Some really good freinds of ours BOTH use them and I put an inverter in their Teton last year down South. The had machines already that they liked and asked if I would do the inverter since they knew we had one in our rig. No problems at all running both all night on the inverter powered by the batteries.

I use a bipap, which is an auto cpap, and the inverter is the answer. If u have a cigarette type plugin lighter it helps.

I have one that runs 12 volts DC through a transformer that plugs into a standard 110 oulet. It will run on 12 volts real well. If you can run off the 12 volt power outlet with out using an invertor, your better off. Your invertor will consumer some of your power through the conversion process. Also, some electronic devices require a Pure Sine Wave invertor, a more costly unit.

My Wife uses one. We added a 12v outlet right next to the 110v outlet on her side of the bed on our Bighorn. When we stay at a location without power, we just plug a 400 watt inverter into the 12v outlet and her cpap into that. Works just fine. If it is very cool by morning, (below 50), the inverter will sometime squeal a little, but we have never had it stop.

I have had a cpap for several years. Mine has two plug ins. One is DC the other is AC. In the Rv I leave it plugged into the DC (lighter plug I installed in closet) While at home it goes into AC. I also have a sailboat that we spend a lot of time on. This of course is DC. I have two batteries in the boat and I run off of just one (so I always have a fresh battery to start engine with) It doesn't consume enough to worry about. If yours isn't a dual voltage, get a small invertor

Dan, most PAPS (C or Bi) use DC (Direct Current (DC) electric) so why convert from DC to AC (inverter) and back ??? it all makes me dizzy ! The maker of your unit probably sells a DC cord which plugs into a cigarette lighter type receptable. We had our dealer install 2 (female cig recepts) near our bed in our BH. We just plug in and life is good ! I can do without the water (Humid's), Patti can't, however the single house battery runs our Paps all night and we charge it in the genny friendly time. Of course, when we camp non-primative we go to 120 AC and destroy the planet earth by not being green... Look at your unit and I'll bet it will run on 12 VDC and all ya need is a adapter cord and a female cig recept from your dealer. Happy Camping !

I use a RESMED Auto Set II. It has ac and dc plug ins. Have used it for several years. The heater plate went out after about three years and they replaced it free.

I know many campgrounds here in ND that have quite hrs for generators, consider those dependent on medical devices exempt. You should inquire with the specific CG before assuming you are safe. But as far as I'm concerned keeping you alive is something I'm prepared to tolerate, specifically if you have a genset that meets the national park decibel standard.

I have a Phillips Respironics System One Bi-Pap with an auto recorder software sim card to record all my sleep events. Every 3 months they send me the results. It only has a plug in, with no batteries, so it requires electricity. They told there is a battery adapter available in November. My guess is that I will need an inverter or genny to dry camp.

Dan,
I run a Bi-PAP on a 250 watt inverter and a Costco Deep Discharge battery runs all night no problem. I turned off the humidifier but I did run the whole deal one night and the battery had plenty of reserve.

I use by cpap while dry camping. My husband installed an inverter so I can run it off the battery. Works great - have been doing so for 3 years.

The resmed auto set 11(great machine) is 110v or 12v if you purchase the seprate transformer cord. I only dry camp and never have any problems with the cpap machine. I use an 8D battery in the trailer and one one on the truck. The one battery on the truck is charged while the truck is driven around during the day. Then at night I hook the truck to the trailer (battery), with plug in connectors.This has worked awsome for me, and really cuts down on the generater time. Due to the extra battery charging needed, an extra battery charger is hooked up to help charge when the generator does run. The extra battery is a must as the resmed will cut out if the voltage drops to low. Also when on 12 volt the cpap humidifer does not work as it uses the most power. If the truck is not driven, the genset needs to be run every third night, this allows one night of moist air! Camping in the mountains and running a small genset is not a problem, as I use a small honda with a long extention cord. Good luck!!!

I am planning a summer vacation with my new elkridge. I have been concerned about how to camp with my new cpap machine. I feel a lot better after reading all your comments. Our fist outing is a dry camp.

thanks

I think you would be fine with an inverter off of the camper battery or a separate battery. I purchased a second battery from Costco to run in parallel on my Bighorn. It can use it just for the inverter if I think the camper battery will get used up on cool nights with the heater running. I did on my JAyco but haven't had enough dry camping on the Bighorn to find out yet. But if its warm enough you won't use the heater, you should have enough capacity on the camper battery to run all night. The inverter I have is only 250 watts non sine wave and it runs the CPAP and heater fine. What type of CPAP do you have?

If yours can run directly off of the 12 volt, it will use less energy to run it. I have had 2 different machines, both have a transformer reducing 110 AC to 12 volt DC, I found the correct plug at an electronics store that matched the one on the transformer cord and wired to a cigarette plug. My batteries do run down as much this way.

My first Heartland (BH 3070RL) is on order. Factory rep at the RV show so am getting a DC plug installed at the factory in the bedroom for $50. Just still need to figure out about DC adapter cord and about keeping batteries charged---may get at least one extra like recommended in this post. But this summer plan to stay in Newhalem Creek (WA) national forest campground for a week --- need to figure best way to keep charged. I have a year old Phillips Respironics

You have the same machine as I do, you can run it on 12 volt DC if you don't use the humidifier. You will have less power consumption than if you run it through a inverter.

I have used a ResMed S8 Elite CPAP w/humidifier since 12/28/07 due to severe sleep apnea. One of my major concerns after being diagnosed was how was I going to dry camp. I solved that issue by installing two dedicated RV Deep Cycle Batteries in the bedroom which are recharged from shore power by a charger/maintainer while parked at home. I power the CPAP with a 600W/300W pure sine wave inverter hooked up to the dedicated batteries. I also have a 15A automatic type battery charger that I can use if needed to recharge the batteries while dry camping by running a generator during the day. I have found that I can get at least 4 nights of sleep without needing to recharge my CPAP dedicated batteries. When we traded our older 5'r in last year for the new Elkridge, it was easy to transfer all this to the new rig. In our old rig the batteries were installed in the closet next to the bed, but in the Elkridge they are installed under the bed(contained in a large plastic tub). I always make sure there is adequate ventilation when recharging the batteries. In almost 5 years of CPAP use, I have only missed 3 nights use due to the inverter blowing a fuse while camping, and those were 3 of the worst nights without much sleep. I now carry extra fuses and know how to replace them in the inverter. You can confidently use a CPAP while dry camping!

ICamel, this same question has poped up several times or more :-)... Most CPaps want 12 DC voltage. If you invert to 120 VAc then convert to 12 VDC you are wasting time and energy !. If you go onto your CPaps website they probably sell a 12 VDC adapter kit (used for car use, etc)... I had 2 - 12 VDC female sockets (cigarette type) installed next to our main bed (my wife and I use CPaps) and tied into the house battery. We just plug in and we're good to go. You DO NOT NEED to invert > convert etc. etc. Your CPaps just needs 12 VDC power. If you put an osciloscope on a 12 DCV battery, you will NOT FIND cleaner 12 VDC power anywhere ! It's the way to go and it's your most simple way. I actually posted a thread a couple years ago explaining this under medical on this site check it out. Happy Camping :-)

Yes, my CPAP can be powered by 12V DC, however the humidifier will not be powered according to the owners manual - "Note: If your flow generator is powered via the DC input, the HumidAire 3i is not powered and humidification output will be reduced". Thank you for your input, but I will stick with what works for me.
