Hopefully it works for you and your needs. Most people only use these batteries for phones, drones or similar devices. Maybe a laptop for a little longer outing. This one works great for that. My R600 pro makes my miter saw mobile. Just rolled it around to the backyard and plug it in. No need to deal with any long cords.
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....

Hopefully some cheaper/simpler options exist but I'm too poor to afford Dewalt stuff....
battery: https://www.amazon.com/gp/product...UTF8&
solar array: https://www.amazon.com/gp/product...UTF8&
cpap adapter (specific for dreamstation): https://www.amazon.com/gp/product...UTF8&
This setup works well for me, to maximize uses without charging I turn off heating on my cpap. OPs product is more power for not much more money so I would have probably gone with it if it was available at that price when I bought my setup.
Even if it is just for 30 minutes a day. Just long enough to keep the basement from flooding.

this thing carries around $.04 worth of electricity.
1kwh from mommy power company typically costs are $.16
meaningless for sure, I just found it amusing.

I'm a DeWalt noob, and only bc of the sales they've been running lately.

Stoked to be getting away from fuel powered tools though!
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 [wikipedia.org]
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.
Poor cell quality or charging circuit quality could lead to cell mismatch in a shorter amount of time than expected, often if you lose a cell, you lose the whole battery pack. If the designer didn't include cell balancing for instance, coupled with cheap unmatched cells, this becomes a more prominent potential issue.
Generally I am all for cheap electronics. If they work, they often keep working. But, it becomes a little more hairy with batteries. When you add in long periods of time for sitting on the shelf, it increases the chances you will pull it out and it will be unexpectedly dead when you need it.

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

I'd like to have a good backup for my Cpap and "BigBlue" should do the trick but for less money I think you could do better?
