Camping...I know, I know....

Okay. I have done some searches. And it's apparent that, as Demosthenes said, "We never, ever do NOTHIN' nice...and easy."

Here's the deal:
Going camping in a week-and-a-half. I want to power my cpap (without the humidity thingy) for a night or two...I can power it up now and then by driving somewhere, or stealing power from the camp host's generator.

I have a ResMed S9. (Grow up. Stop hissing at me, and put down that stupid cross.)

What if I buy this 24 volt power converter:

24v power converter by Battery Power Solutions - Amazon listing: "24V Power Converter for ResMed Air 10/S9 Series and Freedom or C-100 CPAP Battery (Battery Not Included)"

AND a battery:

Amazon listing: TalentCell Rechargeable 72W 132WH 12V/11000mAh 9V/14500mAh 5V/26400mAh DC Output Lithium Ion Battery Pack for LED Strip and CCTV Camera, Portable Li-ion Power Bank, Black

The Amazon Gods seem to think that someone has bought this combination before. The Amazon Gods, however, take perverse pleasure in tormenting mortals.

I have camped before without the cpap...and I didn't die. I looked like this in the morning, though:

And because I didn't think about doing this sooner, I can't even get an appt with my doctor to get his recommendation...and work the insurance system for a higher-priced setup from ResMed.

If I buy this combo and a car charger, can I expect it to work for a night or two?

Thanks in advance.

never heard of it, can't recommend, might work, might not, report back.

the resmed converter, which doesn't cost much more, *does* work, 100%... and a deep cycle battery would provide a lot more power, for about the same money.

I would say absolutely maybe.
Why are you getting the off brand converter? To save a few bucks?
And are you getting the cheap lithium pack because you have to carry it a long way? An AGM battery has three times the power for the same price, albeit much heavier.

there is no evidence that the "24V Power Converter for ResMed Air 10/S9 Series" offered on amazon is any less capable than the overpriced one offered by resmed.
personally i would search craigslist or this forum and look for a respironics cpap then go with a 12v wire and agm battery
afaik - insurance does not/ will not pay for battery adapters or supplies
certainly most docs have no clue when it comes to this stuff that would be wasting your time and money

A few more thoughts now that I'm not thumb typing on a late bus ...
First - what's the issue with the ResMed? It a perfectly fine machine, probably the most popular here. It does have the power supply quirks, but there's a simple solution: buy the Resmed converter. Saving $15 with the off brand converter is like buying day old sushi because its 10% off. If you only go camping once a year its not that big a deal; if you camp frequently then you probably want a travel/backup machine that runs on 12V.
The Lithium pack probably works but the general success rate with this type of pack has been mixed so I wouldn't count on it working unless I had a few weeks to play with it. The 35 AH AGM weighs in at 24 pounds, so its a bit of a pain to haul around, but its certainly doable for a short distance. It can be charged with any regular car battery charger, including from the "cigarette lighter" of any car, and the perfect charger for it is a small, safe BatteryTender. It has triple the power of the Lithium pack and is proven technology that would also be suitable as a home backup.

One more thing ...
So I thought I read here that the ResMed A10 and S9 used different proprietary plugs. If so, can this converter really work?

thanks, capnloki and palerider...

A man's got to know his limitations..and one of mine is losing patience trying to figure out electrical stuff. So I went looking for a plug-and-play solution.

my mistake was using a quick amazon search to try to ballpark the cost of ANY solutions. Problem is, amazon vendors' prices are pretty close to retail-ish. Shoulda known better, based on my experience with buying fishing tackle online.

So I dug a little deeper and found a vendor who has the ResMed power converter for A Fistful of Dollars over the off-brand price. Just like you said... ...as opposed to four times the price, as per amazon. Badda bing, ordered it today.

Since I will be in a campground, weight isn't an issue. I will pick up a BFDCB (Big Freakin' Deep Cycle Battery) at Walmart and be good to go for five nights or so, and have a few nights to test drive the camping setup at home.

All For A Few Dollars More than an off-brand setup that mighta worked, and definitely woulda required recharging drama.

Thanks for the help.

here's hoping you have a great trip, and restful sleep.... at least we know you won't be doing the 'bear call' all night long this time

Well done. I do a lot of one week bike camping trips with my Resmed S9. I have the Airsense 10 at home but already bought the DC to DC Resmed S9 converter and the S9 years previous. So I camp bike with the S9. So the only thing I would add is that without the humidifier it really doesn't pull much power. I used a Goal Zero Sherpa 50 - about the size of a small paperback book for power. If it is sunny, I can pull out the goal zero solar cells around 2pm and may get 3/4 charge by sunset. If there is a plug nearby it is much faster. The Sherpa will do 2.5 full nights - essentially 2 guaranteed. Sometimes use the half to give my iPhone or iPad a good charge. So, long post for short answer. If weight is an issue (on a bike, or in a backpack) - pretty good combo - S9/DCtoDC/ Sherpa 50. Sherpa 50 58Wh, 5200mAh (11V) It is more expensive than a deep cycle but for weight and ease of use - works like a charm.

i had no idea the Sherpa 50 would do that well. im about to get the Yeti.....ive read itll get 3 nights on machine alone (no humidifier)

for the price difference the sherpa might be my way to go......

I'm a bit skeptical- 58 Watt hours is not a lot of power to go over 2 nights. At a pressure of 9.5, my respironics 560 uses over 48 Watt hours a 8 hour night and the ResMed S9 power usage numbers are a tad worse. I can only guess that the pressure is low and/or the nights are short. Also, quality batteries often out perform their specs when new and then settle in to their rated power.

In the ResMed doc below, the lowest current draw (at pressure 6) is 0.39 amps which is 37 watt-hours for an 8 hour night.

Agreed, it's all about pressure. When I first got my Z1 (45wh battery) I got almost 15 hours at my pressure of 9. Then another sleep study and I needed to go up to 14-20. Now I get about 5.5 hours on the same battery.

Hey folks,

Any updates to this topic? I haven't been able to camp for a couple of years.
looking to get back into it!

BTW: My Puritan Bennett 420G looks alot like the CPAP Respironics RemStar Pro. Does anyone know if they are the same basic machine?

Thx

Are Fords and Chevies the same, not very Likely, but you know, Jim
