Power outage CPAP solution

[Jsf721]

I did not post this because it was never battle tested. Now it has been. I purchased this unit when I purchased my second jump pack from them.

The company is Antigravity battery. Sold on line.
My unit was purchased sometime in late 2021 or early 2022. It was charged fully and put away.

I had power go out last night around 1pm. My CPAP went out and it woke me up instantly. Took my some time to find this thing but once I did I hit the power button and boom it was 100 percent charged. Ran it Fromm 1:30-3:45 when the power jumped back on I plugged it back in the wall and shut this down. it was at 98%. If it burns 1% an hour I’ll be thrilled. Not sure is discharge is linear.

Good solution for CPAP and also charging phones off the grid. They make a solar panel to charge this for travel off the grid and I may but that now bc this thing has proven worthy.

I use a 3D printed adapter for an 18v Milwaukee battery, with an 18v to 24v converter. It works well for camping, and a big battery will last the night.

Which output are you using? Most ResMed machines run on 24VDC, and if you can find the right adapter for your machine and if it works from the 24V output, my guess is you'll more than double the run-time by pulling DC from the battery vs pulling 120VAC and double converting through your AC power supply. ResMed also makes 12V car powered supplies that should be equally efficient (though more expensive).

Not that I'm suggesting you run without humidifier in the winter, but humidifiers (depending on your pressure), can be 75% of your CPAP energy budget. The disposable humidifier made for the Air Mini (travel CPAP) in basically an in-line ERV that works in your hose and retains your exhaled moisture. It's not as good as a heated water tank, but for prolonged outages (from a hurricane, not a windstorm like this), that can also greatly stretch your battery capacity.

Jeff, do you have an adapter like this:

I run my CPAP machine (ResMed AirSense 10 Respond) with distilled water nightly, but without the heater turned on...
It's able to keep my sinus and throat from drying out at night...
I didn't like the water condensing in the heated tube causing a gurgling sound from collecting in the hose low spots...
Running it without the heater would certainly extend the battery life...

Condensation in the tube is bad for many reasons. Gurgling can turn into a tidal wave of water that shoots into your nose when the puddle that's collected in a low spot is disturbed as you turn over. It's also a breeding ground for bad stuff, so yeah, keeping the hose dry is critical.

But if you're getting rain out (what it's normally called), either your tube isn't heated enough (wrong setting?), or your room is too cold (like me). I found that a fleece hose cover that helps keep the tube warm can make a big difference. But I was still getting rain out in the last foot of tubing that's part of my mask (so it has no heat). I just made a cover for that bit a few days ago, and now I am able to humidify at auto-auto without any gurgling.

My backup solution:

 

[reader2580]

I have an Anker 521 Power Station that will power my CPAP for a night with humidification, or two to three nights with no humidification. I have a Dreamstation CPAP that is 12 volt and used a genuine Philips Respironics 12 volt cord.

My understanding is the Power Station can be used as a UPS to back up a CPAP in case power fails. I used mine for tent camping at an event for two weeks, but I had access to power during the day to charge the Power Station. I had the humidifier turned off so I only charged every second or third day based on how much was left in the morning.

You need to edit the title to outage instead of outrage

Thanks for the info. I plugged into the outlet on the above unit. I’ll post a better picture. So far it’s been great the one time I used it.

I don’t run a humidifier- ever and yes it dries me out but I know me and I won’t clean it as often as I should and I’ll muck it up. lol. I can suffer through a lot with a smile.

What is that cord used for ?

Done

 

[rlitman]

...What is that cord used for ?

It's from a different CPAP battery bank, meant to plug into the 24V output plug and bypass your machine's power supply entirely, powering the machine directly off of the unit. The top adapter plugs into an S9, the middle one with the yellow end works in an AirMini or Airsense 11, and the wire goes straight into an Airsense 10.

I've just always plugged into a small UPS. Clean power and battery backup if needed.
CyberPower 625VA. Also has USB charging outlets for my phone & watch.

Must be noisy sitting next to the bed.

It's noisy for my neighbor's bedroom since it's at the back of the house.

I have one of these and have used it several times to run my CPAP. Anywhere from about 4 hours to a full 8 hours and it has never let me down. My CPAP runs on a pre-programmed setting of 16 which, if you know CPAPs, is very high. I believe the highest setting is 18. I always run the humidifier. Usually on a setting of 1 or 2 depending.https://www.amazon.com/gp/product/B07D29QNMJ/?tag=atomicindus08-20

I'm building a portable Power Station with a 100 Ah battery. Originally I planned to run my ResMed Air mini on an inverter but found the dc adapter cord mentoined up thread. I wired in a 7 pin receptacle with just hot and ground wires and I will plug my horse trailer into it to power all the 12 v lights and USB / lighter outlets I installed in the tack room.

Step 2 (next weekend) will be to wire in the solar charge controller. Found a couple second hand 100 watt solar panels

step 3 will be to install an inverter and fan in the case.
