capacity, price, portability, ease of use, not to mention battery chemistry which affects # of cycles and shelf life...
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.
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.
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.or
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.
...while you're looking up stuff, look up what "generate" means as well

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.
Can a 300W inverter like this one:

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....

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