I ended up going with a Blueti AC200P after comparing them to the Ecoflow units. The Bluettis have the advantage of using LifePO4 cell chemistry, which gives them a cycle count in the 2000-3000 range, while the Ecoflows that use the more 'conventional' Li-NMC - like we use in our ebikes - give the expected 800 cycles if treated gently (ecoFlow specs only 500 cycles if charged to 80% on the Delta's spec sheet). Other benefits of LifePO4 are that it is more tolerant of leaving it sitting in a high charge state - so you can leave it fully charged and ready for a power outage for example - and better tolerance for depth of discharge so you can drain it without such severe consequences to cell longevity. Also much less volatile/explosive like the li-ion cells we all know and love so there's a big safety benefit there.
On the flip side, LifePO4 is is less energy-dense, so to get the same kind of performance you need a bigger battery. This was the one drawback that meant anything to me as the AC200P weighs I think 61 lbs as a direct result of the batteries.
They sell an AC200Max that I would stay away from. Teething pains on it. The AC200P is one model back and cheaper. I bought mine while the 200Max had come on the mkt and no regrets. 1599 on Amazon.
I use the AC200P and three 200w portable panels when I go off-grid camping in the lower Sierras to re-charge my ebike. In the pic you can see I am getting over 400w in from those three panels out in the back yard, which can recharge the 2000wh unit fully from about 7 am to 1 pm. the amperage reading of 0.09 was momentary when the pic snapped. I get about 10a and 480-ish watts typically.
those panels, by the way, are pricey. they go on sale with big discounts regularly. I sure as hell didn't pay $499 each for my 3. And there are competitor panels out there that are just as good if not better. The Bluetti panels use Sunpower cells which are maybe industry-best for off-angle collection, but wired in such a way that they suffer severely if there is any shading.

I have an AC300 plus 3 B300 batteries on order along with ten used Sunpower 200w panels I got for $70 each (commercial building take-offs) used that I will be integrating into a quasi-DIY home solar install (I buy the parts and do the solar eq setup, electrician does the tie-in into the home).
