CPAP Battery for Boondocking

We have a week long houseboat trip planned for next summer. Both my wife and son are on CPAP machines and the boat specifically advises against using their power for CPAPS. My son and I both came to different solutions.

He bought a Jackery power station and the foldable 100 watt solar accessory. He used it on his Dream Station machine for a night and it drew down 8% of useable power.

I bought a Battle Born 100AH Lithium battery for our trailer and plan to install it in my MinKota battery carry case and take that. I will also take my 60 amp trailer charger with us to top off the battery if it gets low. Should take about an hour on the daily generator run. The case makes it easier to carry (32#) and serves an additional use for my trolling motor. We bought a 12V power cord from Amazon (around $40) and have tested everything in our trailer, works good. The battery was expensive but offers me many other advantages with the trailer. I didn't mind, can't put a price on health.

i used two battery chargers with built in inverters while i was hunting in idaho wilderness each one lasted 6 hours per night for 2 nights so if you are able to charge them during the day you would only need one they cost a little over a hundred bucks but were well worth it walmart carries them they have 120 volt plugs on them. Stanley peak 1200 amp chargers are what i see on their website now

So, just circling back to close out the thread. I ended up buying a DC power plug for my CPAP, and this from Amazon.

Tried it last night. After wearing the CPAP for 8 hours, this still had 83% battery life left. So, for anyone looking for a solution, this one seems to work.

After almost 7 years of using my CPAP on the coach's 12V battery system, I added a small electric refrigerator and there was no longer enough juice to go around. My solution was to purchase two small lithium "solar generators." They won't run the CPAP on 12V (not enough amps on that port), but the CPAP runs fine when using their built-in inverters. Each cost less than $200 with coupons found on Amazon or on YouTube reviews, they are light enough for me to lift easily, they recharge quickly from the truck alternator when I drive, and each powers the CPAP for 2 nights without humidifier.

Caution: The results for your Dreamstation will be different. My camping CPAP is an old Phillips 60W. My HMO recently stopped supporting my old faithful CPAP and they gave me a new one which draws 90W and won't work on my RV's electrical setup. The old one still works and I can buy filters and such from CPAP.com, but my insurance won't pay for that. Insurance also did not pay for the 12V cord to use in the RV or for my two little power supplies.

Buying two may not be what you need, but think about it. Two small ones are cheaper than one big one, you can charge one while you use the other, and if one fails you still have the other one.

If you can put in a 12v outlet near the bed, this 12 volt cord will probably work fine. Like others have said, the heated humidifier is the biggest power hog on the machine

Concur ! Much more efficient than running the CPAP off of an inverter. If you have a pair of 6v golf cart batteries and are NOT running any other items over night, I think you will do fine.

Spend the money and get a battery monitor like a Victron BMV-700. This way you will know exactly how much power you have in the batteries.

since bionic man has insurance, why are folks suggesting he pays out of pocket for one? as far as masks go, I have settled on a ResMed swift FX Bella gray after trying at least a dozen different masks. as far as set up/etc. the amount of pressure required should have been established initially by the Dr. and mine hasn't changed for 20? years. is 9.

I don’t mind paying cash for this. The respiratory therapist gave me a pamphlet on one made by the company that makes the cpap. But also advised me to just go on Amazon and pick one up.

I was thinking something like this.

Ahh. Houseboat. Different scenario indeed.

Since you have about a month before your trip, I would pick up a Kill A Watt and plug your CPAP into it to see how much power you're actually using per night. Then you can compare your nightly usage to the capacity of the battery to see for yourself whether it will work.

And here's a workable link to the battery: CLICKY.

Good luck.

Clicky doesn't work but url does. That unit *should* work, but you'll need to verify the power consumption of the Cpap to make sure.

Even if you are camping far away from others, running a generator eighth hours a day is a pain. With adequate solar panels and batteries on most days you won’t need the generator at all. Since this will unfortunately be a continual issue, get solar.
