Great price for a delta max 1600 with expanding capabilites. can handle 2000 watts and surge to 5000w. also has the ability to add two extra max batteries bringing this capability up to approx 5600 watts.
This is a refurb with a 2 yr ebay warranty.
And before the critics chime in, it is Li-on but great for emergency infrequent use as a home power backup source for major appliances.

Sure, that is true. But doesn't make it a generator.
For occasional backup or portable use, Li-ion is the way to go.
For frequent use, LiFePo4.

edit - maybe good for camping?

The two main uses are emergency backup power, and off grid use (camping).
The first use is the main reason I bought mine. Wildfires, high wind events, etc PG&E likes to turn off the power for undisclosed amounts of time. Obviously, I have a generator suitable to run the whole house, but it's not a good idea to run it constantly just to keep the fridge cold, especially when roads are shut down and gas supply is dwindling. Instead, my ecoflow can run my fridge and internet (only communication where i live) for 28hrs on one charge. Run the gen for 1.5hrs and I'm good for another day. I also have 250w worth of solar panels to keep it topped off for those major outages.
Even for shorter outages, I'll plug the TV and fridge into it so I don't have to lug out the generator for a short 6hr outage.
Also a plus for camping, running lights around the campsite or when we have older family members with us to run small appliances they just can't live without.
These aren't for everyone if you don't have a use case, but if you do have a use case, they are great. Mine has almost paid for itself in gas savings alone, plus the PG&E rebate I got on it too ($500 rebate.)

If you think about how long your ups batteries last (3-4 years, then it barely gives you 2 minutes) youre still aging out the batteries.
You can certainly set the parameters on these (not all mfg give you the ability to set the top off percentage) so that you could leave it at 85 percent for longer life.
Do realize however that these have non serviceable batteries, unlike real ups units.
To each their own (and I have many of these types of units) but I run real ups units for critical loads like the fridge and internet. You can get 1500w ups units for around 120ish. Replace battery every 3-4 years for about 40 bucks.
Realistically a lot more things are using lithium instead of sla, including backup batteries for modems, phones, and routers. I've torn apart second hand battery packs for these for 18650 reuse, and probably 98 percent still worked well during a charge discharge testing cycle. (with a sample size of a few hundred).
Those packs were in machines at full charge for most of their duration of use (3 years before the mfg replaced them). For them to still perform well after 7 years of being mfg tells me that I shouldn't be too concerned with overall longevity.
