Home Use During Power Interruption

[MoneyPit1946]

Please excuse this rather long post but my question needs some background.

I've replaced my "ancient" Respironics CPAP for a much better ResMed Airsense 10 Elite.


The problem now is the Ac/Dc adapter cord from my old machine is defiantly different from my new machine. The "brick like" transformer is bigger and the plug on the power cord is larger on the new machine.

Previously, I've used a " lawn & garden " deep cycle 12V battery with a "battery maintainer" hooked continuously to the battery using a wire harness I purchased on-line somewhere? When/if the power goes out, I simply unplug the AC cord from the machine and plugin the DC cord. Simple and has worked for many years.

What I need now is a "harness" with alligator clips to connect to the battery and to connect directly to the power inlet of my ResMed 10. I've seen many of these harnesses on-line but most have the "cigarette' lighter plug, which I don't need and I'm VERY confused as some state 12/24volt, obviously I don't want to damage my machine with voltage differences.

Does anyone have a link/experience with running my specific machine on battery power at home?

Thanks:  Dave

Yes, I have a airsense 10 and I use a 300 wh lipo battery power station along with a 12 v to 24
Adapter cord. It runs directly off the battery and not the inverter.

I bought both on Amazon . With the humidifier on OFF and no heated hose, I can get 35 hrs on a single charge. I also leave water in the tank for a little moisture.

Do a little research on battery technology , Lipo batteries fit the bill.

This is the converter cord I use.

My unit and many others have a cig lighter socket that works with above cord.

You can also buy the above adapter and a cig socket with alligator clips and just use your existing battery.
All on Amazon.

Your Resmed is 24 volts so you need the adapter to convert your 12 volt battery to 24volts. Mine works great along with many others . It’s the only way to use the 12 volt battery supply.

Thanks for your information. That part about my unit being 24 volt my my standby battery being 12 volt was my concern. So this adapter that you're are using will work for both 12 & 24 volt?

Please indicated which one you have in this list. 
Thanks: Dave

The $59.95 one. That will work. Your Resmed is 24 volts. Your Battery is 12 volts. So the adapter permits the battery to power your Resmed.

It’s the same principle as the Resmed transformer brick that came with your unit. It converts 110 volt from your home to run your 24 volt Resmed.

Great. I ordered that one.

And this to I hope.

I'm hoping to use my (old) DC power cord? I'll see what I need when the harness comes in.

Thanks: Dave.

I got in a jam last night. Which power station did you buy?

 Both of those should work with your battery. Did you try them yet?
