CPAP Lightweight Battery Pack
Jan 11th, 2016 at 4:38pm

I was talking with Old Salt ( a CPAP user)  about what I use for a battery setup for my CPAP machine when I  go paddling in the Q. He suggested I post it in the QJ Gear Forum.

In 2012 I bought a Lightweight Travel Lithium Battery Pack for ResMed CPAP Machine from a website (You need to Login or Register to view media files and links)

I am not sure if the battery technology has gotten better since I purchased  this CPAP setup in 2012 but this Lithium Battery Pack has served me well. It is a bit on the expensive side $299 but it is the lightest system I could find. Right now on sale at  cpapxchange for $297.99

The unit consists of a 12 volt converter that plugs into 12 rechargeable Lithium ion batteries tied in series and then plugs into my Resmed9 CPAP machine. I take off the humidifier when I go paddling since it uses more battery power. I can get 2  nights sleep per battery pack averaging 16 hours total per battery pack. I bring along 4 lithium battery packs with me and they weigh about 1.5 lbs. each. I do not recharge them on my trip.

I found this system to be lighter than most battery setups but I am still hoping that I can someday get the weight down even further.  There is a new light weight travel CPAP machine called "Transcend" that is advertising on the radio that looks like a possibility.

3 years ago I was diagnosed with severe sleep apnea using a sleep test and my Resmed9 machine and my Resmed AirFit P10 mask has been a God send. I can't sleep without CPAP. I have tried oral devices etc. and these substitutes just don't measure up. 

I have used this set up the last 3 trips to Quetico and it has worked well. CPAP users may want to give it a try.

Mike,

I enjoyed our visit last night, and especially appreciate your recommendations. Coincidentally, MP sent me a pm regarding CPAPs. When two QJers contact me on the same day, concerned for my health, I listen. Wink This looks like what I have been looking for for many years. If you depend on CPAP, look into this. When I buy one, it will not only serve me well for Q, but also for any travel, (I like to go to Alaska), but also for those inconvenient times when the power goes out.

Sleep apnea is a killer, especially when combined with other health problems, so look into it. Thanks! Cool

Rich,

I just talked to a gal at CpapXchange and she told me that you would have to "special order" the lithium 12 AA battery pack with connector for $184 per pack...ouch   One battery pack comes with the $279 package with converter and bag etc. But since one battery pack will only do 2 nights on a Resmed9 you will have to order extra battery packs for your overnight trips ... unless you can figure out a lightweight and reliable system to recharge them in the wilderness. Solar ?

Mike

If you cook with a fire, this might do the trick IF it can charge those Lithium batteries? Solar can be iffy, but you can always find something to burn.

Wally 13 thought it was worth mentioning but I get a eye roll and this  Lips Sealed

IF you didn't/don't want feedback from the Open Forum you should take it private.

I dunno. Perhaps you're correct, a wood burning camp stove is a good way to recharge lithium batteries? It could be. Please run a few tests and post results.

All the battery manufactures try to pack their batteries in the smallest pack they can and they all get about the same power density.  So the weight or volume of a certain capacity battery by different companies will be about the same. Using this information on the cpapXchange battery I would estimate it to be about a 8000mAh battery.  That may help if you are considering a different battery system.

I'm wondering if one could hook up 12 rechargeable lithium AA batteries in series cheaper than their option? MP? I certainly wouldn't want to void the warranty... Cool

These reviews seem very positive about the BioLite's charging ability, the question then is could it charge that Lithium Power-pack?

MP is the electrical expert here; maybe he could speak to it?

These are for the larger Basecamp model.

Biolite makes many charging type units that “might” be good for things like fish finders  IF they produce enough power?

IF your cooking a evening meal and could keep your batteries "topped" off at the same-time, it "might" be a good thing?
