2 nights without electricity (so far)

[Janknitz]

i have a system I set up in case of power outages. i tested on battery for couple of days but, fortunately have not needed it. The battery shpuld be able to run the CPAP for 2 or 3 nights without heated hose or heated humidifier (passover should work).

Resmed DC power converter https://www.cpap.com/productpage/resmed ... 0-machines

12 volt 35 AH battery https://www.harborfreight.com/12-volt-3 ... 64102.html

solar panel kit (also has some lights) https://www.harborfreight.com/100-watt- ... 63585.html

The solar panels can keep the battery charged & ready for use too.

This solution does not help us for drinking water from our well. We have a pond to draw on for toilet flushing though.

Thank you!

When we lived on catchment in Hawaii, we'd fill the bathtub before planned outages and use a bucket to flush the toilet. We had bottled water for drinking and kitchen use during power outages. Luckily, they were short so I didn't have to do the pioneer sponge bath routine.

I'd love a tutorial (step by step for dummies!) on how to set up a battery system for PAP starting with a list of supplies to purchase and then step by step what to do, battery maintenance, safety, and bonus points if it also includes instructions how to set it up to recharge by solar. Anybody game to help me with that (it would be a great resource for the forum!)???

Capnloki has a great post about what batteries to get, the charger, all the stuff needed to make a battery system to last an easy week, even more if you get a solar panel for it.

It's in his sig... He knows his battery stuff.

Okay, people who are smarter than me:

First, thank you, Prodigy, for the list of DIY stuff.

I'm also looking at some portable power stations on Amazon that say they can run CPAP (Example: https://www.amazon.com/dp/B07MQQY11K/re ... NrPXRydWU=)

More expensive, but just seems a bit easier and safer to me.

The company recommends a dc converter for CPAP--will this one (https://www.cpap.com/productpage/resmed ... eviews-tab) work with that power station--I can't tell if it has the right output port for this converter?

This power station has regular 110 v outlets and one person said it works well for his ResMed. From the specs, can someone smarter than me tell me if it's really necessary to use the DC converter to get 7+ hours or so of use without the humidifier running or could I get that much time from the 110 volt outlet?

When you have something like this, is it prudent/safe to leave it plugged in so that it will be charged up and ready to go for an unexpected power outage? Or will it hold a charge if I charge it up when it may not be used for many months or even a year?

Honestly, a big pile of lithium batteries (remember the bursting into flame phones and computers a few years ago) in the bedroom might be debatable as far as safety.

Lead acid probably are safer, all things considered... After all, when was the last time your car battery blew up?

[prodigyplace]

The AGM battery I listed is basis no spill lead acid battery similar to the one used in some cars.

You know what's a better guide?

What post there has the electrical details for the ResMed devices to determine needed capacity? That other document has those details.

Which one has a better "guide to build a backup supply"? Not the one that throws far too much information at people that have zero knowledge about the subject and just want to build a nice, safe battery backup system.

My point is you link is not better, just the next step. You need to know what your goal is before you can try to hit it. You need to know how much battery capacity your machine requires before choosing how best to supply the power.

my point is that you're wrong.

Confusing people with a ton of irrelevant information is not helpful.

Capnloki's guide to building a battery system handles all that's necessary, without confusing irrelevancies whether you want to believe it or not,

Okay....CapnLoki has a good primer but it still is TMI for people like me and Jan whose eyes glaze over when we try to read his primer.
Some things I am good at understanding but this battery stuff I just can't wrap my brain around and I really don't want to try very hard either. I got enough stuff on my plate as it is and I know that there are some things in life that I probably will never get a good grip on and I am content accepting that fact.

What I would like to see is someone give me a list...
A "YOU NEED THIS" list so I don't have to fire up the brain cells and think because I just can't think clearly with my eyes glazed over.

Maybe someone could come up with a couple of primer lists....one for at home battery power and one for camping/hiking where weight is a strong factor.
Just give us a shopping list and we go shopping.
Oh...and maybe a list that would include using the humidifier....I don't think I would/could use my machine without my humidifier cranking out moisture. I tried a setting of 2 once long ago and that was a major disaster. I would do without cpap before I would do without added moisture.

That's the first link in his battery thread... maybe I should list it, instead:

You'd just need more, or bigger, batteries to run the humidifier. Also listed in that link.
