Pretty different solutions overall.
capacity, price, portability, ease of use, not to mention battery chemistry which affects # of cycles and shelf life...
Quote from lilgrubbybaby :
Your Ah calculation for this unit is a decimal place off.

Years aren't really meaningful if you're not mentioning usage and capacity loss over those years, the chemistry of the batteries make for pretty different usage. You will be able to discharge more total power from a lithium battery with 1/5th the capacity of a lead acid battery over their lifetimes, the capacity loss really is that different.
The Ah calculation is for the deep cycle battery.

You may be right about about the capacity loss and the different chemistry comparing it to lithium batteries but you will likely have to go with a much lower capacity (as you mentioned) and likely go with an unknown brand taking a risk there. I'm not sure there is a one size fits all solution, BigBlue may be perfect same with off-brand lithium batteries but a traditional deep cycle battery with big power has it's place too.

I've never had the need for backup power but I'm looking for something that can last my cpap for a few days and perhaps I can even plug in a coffee maker but that's of a much lower priority.

You are right.

Actually, there are no such thing as generator. Even your conventional gas generator doesn't generate energy. It is just converting stored chemical energy from the petrol to a usable form like electricity. That's the law of conservation of energy . https://en.wikipedia.org/wiki/Con..._of_energy

Now add a solar panel to this listed product and you will also be able to convert the sun rays to a useable electricity. The good thing is, you will also be able to store that energy from the sun in to this product and use it when it is needed.

Again, there's no such thing as a generator. You cannot generate energy. You can only convert it to one form to another.
there are degenerates for sure though nod

...while you're looking up stuff, look up what "generate" means as well

Bingo and to further compare, one of them you can operate indoors because it doesn't emit carbon monoxide. You can run it all night because it's not loud. Doesn't require maintenance like oil changes, fuel additives, spark plugs...etc.

What product do you use for your CPAP and do you have a link or suggestion?
Ideally you want to get a car adapter for your cpap, it will use a lot less power that way.

This thing is okay. I have the same unit from a different Chinese factory. The capacity is accurate but the 12v output is unregulated. Pretty good for $150.

I moderate solar generator groups on Facebook for three different companies so feel free to ask any questions if you're genuinely interested.
Do you think the Bluettis and Jackerys of the world are worth the premium vs. these no name chinese brands? I have both and am starting to lean towards the cheaper brands.

Did anyone else wonder why it's called "Big Blue," but it's orange?

They don't call it one. Anker sells a similar product and calls it a generator. I think power station is a fair name for it.
did you click on the Amazon link...........

Ehhhh, if you're going to lose power enough in the next 3 years... maybe.
With non replaceable batteries, I wouldn't count on this beyond that.
If you loose power frequently, a small generator can be about the same cost, and should work beyond 3 years.

If you just want to be ready and have any cordless power tools, getting the USB charging adapter is my preferred route. Since you'll get use out of those batteries even if there isn't an outage during the batteries lifetimes.
This is the real trick!

Can a 300W inverter like this one:

https://www.mercari.com/us/item/m20100572029

Its $74, and now you're done ASSUMING you have a bunch of 60V greenworks batteries. I already have 2 from my lawnmower and trimmer. Those things are a beast, like the lawnmower is a 4aH battery, so thats 240wH! That'll keep even a 40W small PC running for 4 hours! Or let you recharge your phone 20 times. Also, more likely to already be fully charged before a blackout....

Your paying for convenience. You could buy 3 8ah lifepo4 batteries from amazon for 90 bucks. But then you'd have to get them to work together in parallel. Plus add in a nice inverter to be able to use it. Don't forget the charger. That only makes sense if you plan to take advantage of it and initially your not saving much if anything and spending more time.
Exactly! It is all about this working - in one case that you can easily carry around. Now, I have an EcoFlow Delta 1300 so I think this is a little small and as you know, won't operate anything significant for long.

Pick the smaller of the two. I would not recommend going that route. I was only using it as an example.
