Good day,

I came upon this wonderful forum and am looking forward to participating in this community.

I have a ResMed S8 Elite and was wondering what would be the best (yet, most cost efficient) power supply for such a device.  I would like to be able to go camping for 2 days but if I go to a place with no electricity, I essentially have to pass and stay home.  I would like to have something that is available in case of a storm that knocks out power for a couple of days, and for trips out.  I understand the eliminator brand from Canadian Tire is good, but would like to confirm with someone who has a similar make of CPAP how long (without a humidifier, at level 15) it will run for.

I greatly appreciate any advise you can provide me with.  Thanks!

Do you mean camping like KOA camping or deep in the woods Yukon camping? At KOA or similar campgrounds, we would do the tent thing but now with having to bring the PAP we opt for a cabin. which has electricity. Its a few bucks more but it has what i need with almost the same feeling of the outdoors.

I would prefer cabin camping with electricity; however, my wife's friend invites us every year to this "cabin" that she owns.  It has no electricity and no running water, but it has a roof and walls (barely).  But, of course, we can't stay overnight and the 2 hour drive often discourages us, since we would have to leave early in the morning and then leave late at night in order to get a full day in.  That includes no drinking after a particular time since we will be driving later that evening.  I just want to be able to bring the CPAP machine along (with the power source) and not ruin the fun for everyone.  I also always worry about power outages and how if it prolongs into the night, that I can simply plug in the CPAP instead of waiting for the power to return.

You said no heat-humidification.. that makes this simplier.

But, I would try not using heat/humidification at home before you go on the trip. You can fill the chamber with water and just not turn the heat on.

I can't go more than 1-2 days without heat/humidification before it feels like someone took a bottle brush and rammed it up my nose.. (not pleasant). The nasal irrigation sprays.. like NeilMed makes help.

ResMed makes a 12-volt power cord. You can get the amperage draws for your CPAP at various pressures from the ResMed web site.

I've used the 12/V cord sleeping in the back of the van locally with no problems. Also consider how cold it will be when and where you are planning to camp. You need to be careful about hypothermia. Think about that unheated volume of air being blown down into your lungs.

I sleep in a semi-truck on CPAP. When trying not to run the engine on nights in the 50-60 degre range. waking up shivering is not uncommon. I just helped another truck driver who woke up.. delerious semi-concious.. he had stopped shivering and was probably in a later stage of hypothermia.... sleeping in an unheated truck on CPAP on battery power.


also google - check   batterypowersolutions    they were a vendor at the American Academy of Sleep Medicine conference. They market a series of battery packs and invertors designed for running CPAP either camping or as a back up for power failures.


Good Luck

I camp a lot with my cpap, but we have a trailer which has the 12V outlet, so I bought that power cord (it was $75!!). We have 2 batteries on the trailer and a solar panel which charges them. The trips where it's been cloudy I can go about 3 days before the batteries die. My pressure is 10. I also leave the humidifier on the machine, but turned off. This last time I was awoken early in the morning to my cpap turning on and off, so I took the humidifier off and it worked fine for a few more hours. Not sure why. Hubby thinks maybe we need new batteries.

Before we had this trailer I borrowed a friend's generator and plugged it into that. Not ideal, as his generator would run out of gas after about 4 hours of sleep, plus it was loud!

I guess I forgot to mention that I have the same CPAP as you do.

If you are camping in cool weather, the Aussie heated hose, which operates from 12 volts, may be a good deal.  During the winter I let my bedroom get cool; into the 50's, and the Aussie heated hose keeps the air bearable.

I haven't checked with my new CPAP, but my old one ran just fine (sans heat on humidifier) from a 1500 watt (i think it was) sine-wave inverter off of a couple deep-cycle batteries during an almost weeklong power outage.

Hi everybody!

First of all, I want to thank my daughter, JKL, for finding this forum for me!
I'm a 68 year old male, and have used a Tranquility Quest for the last 12 years.
I've taken it to Europe, where it works, because it can take either 100-120 or 200-240 volts,
although I need an adaptor plug, which you can get at the Las Vegas airport.

I am about to go on a camping, and I want to thank Gman for giving me a solution: get
a battery pack and an inverter.  

Here is my question: How much power does the Tranquility Quest draw?  How many watts?
Or, how many amperes at 120 volts?  Does anyone know?  I'm trying to find out  

Thanks.

12 years.......same machine.
I doubt too many here will know a lot about the Tranquility Quest...........I haven't heard it mentioned in many years.
I think you should contact the DME that sold you the machine. They may have the data.

Daniel.

Hi,

I found the answer on a respironics web site: http://global.respironics.com/UserGuides/UserGuideTranquilityQuest.pdf
The Tranquility Quest should not draw more than 3 amps under normal conditions.
