HELP Can you give advice on backup battery for cpap?

In May I started using a cpap machine. I didn’t think I’d ever “get used to it”, but now I’m not so sure I’d be able to sleep without it.

What do you use for battery backup for this in the event of a power outage? I found some “mobile power packs” on amazon but not sure they’d work. I read something about getting an inverter and having it run dc but have no idea how this works or what I’d need.

Can you please post any tried and true links / sources / info that might guide me in the right direction? I appreciate it very much! Thank you!

My dad has one of those back up power things that will run a computer in the event of a power outage. It looks like a surge protector on steroids. I'm not sure if that will work or not but it might be something to look into.

Might also want to cotact the manufacturer or where you bought it from to see what they recommend. As a standard though a RV class deep cycle battery and an inverter big enough to run it should get you through a night or two I would imagine. And then of course a battery charger as well.

I use a car battery and an inverter 750 watts, continuous with a peak of like 1500, will run the wife's and my bypaps for 2 nights without a recharge. Also use this setup for camping, and sometimes we also run a fan with it to keep cool. Of course I also have a battery charger for when the power comes back on.

I was put on a cpap around 12 years ago. Used it every night. Could not sleep without it. Then my wife bought me a recliner and I started falling asleep on it. What I needed was to have my head in a raised position. Now I don't worry about no having power for my CPAP.

Does yours run on 12VDC? (mine does). If so a battery and a small charger will take care of it.

Kathy in FL also made a good suggestion. A computer UPS will, indeed, work. I had one on my cpap for a long time until it died. I need to get another one one of these days.

If you are running off battery, make sure that you turn off the humidifier since that uses a lot more current than the CPAP alone.

It would help immensely to know the make and model of your machine. If you think you might lose power for more than a day or two you might be better off to buy a generator.

My W uses a cpap, was forced in the RV to make these mods. I run 6v golf cart batteries work better than a deep cycle battery, I use a 1500w inverter good grade, and solar panels to recharge batteries. Have found that during day use of generator would not fully charge batteries and had to run generator at night. There are formulas on internet for sizing batteries for load.

Right. You have to decide how long you want to run the machine. Then read the data plate for its power draw. Then size the battery for power consumed x hours desired (I’d add 20% to the number). Then buy the battery/inverter accordingly.

Note that recharging WILL be necessary, so you’ll need a recharging system as well.

Providing power to things is not just going to Home Depot and “buying a thing.”

Battery backup units for PCs are really unnecessary these days since most people have migrated off desktops for laptops.

Just passing through...
...but I can say with some confidence that a CPAP that is designed to run off of 12V DC will be much more efficient than something that has to covert battery power to 120V AC.
