Hey All! I did a search for all threads with "cpap" in the subject line and read a handful of them... and this one was the longest and had the most details, so hopefully it's also the best place to post my question!
The SF Bay Area has had a lot of blackouts and my girlfriend's elderly Grandfather wants a battery backup for his ResMed AirSense 10 Elite CPAP machine.
From what I'm reading, there are a few things I'm contending with:
- He wants it to basically act like a UPS where he's got it plugged in all the time, and if power goes off, it will still be functioning just fine (from what I understand, most power systems / boxes will turn off if not pulling current, so he'd have to manually turn on the power box, no?)
- He'd like it to last 2-3 days with the humidity / heater on (if I'm reading the threads correctly, this uses about 200Wh per night)
- This unit uses 24v (I could use a 12v DC to 24v DC voltage converter... but I think the plug is weird... see my next point)
- It has a proprietary plug (I think there are some on Amazon that plug into cigarette lighter adapters and also do the 12v to 24v conversion)
Again, this isn't for camping, and ideally he could always just have it plugged in and working off the battery... with some kind of always-on pass-through charging from a wall adapter to the battery, then the battery to DC 24 volts (either using a cheap 24v up-converter or one off amazon)... but I'm not sure if this is the way to go?
So, what would you do? Would one of the "solar generators" like the Ecoflow, Bluetti, etc. work, or are they not designed to be on 24/7 and only pushing power 8 hours a night?
THANK YOU!!!
