Best praise vs top criticism for EcoFlow DELTA 2
Best Praise
+52 pts“A shame that the original post has gone, but I'll share my experiences anyway. I used to own an Ecoflow Delta 2 for my log cabin which I loved - it worked really well with about 1.8kW power delivery (could boil a travel kettle using it), but I found that it wasn't quite enough capacity to last a full weekend. We had a 50W coolbox attached to it, and it would be flat after a day. One thing you've got to realize is that the capacity that the manufacturer says you're getting is not what you actually get - this is because the inverter, display and fans all take energy, and in fact the useable amount of capacity on the Delta 2 was only about 800Wh. Talking of fans - the fans on the Delta 2 were REALLY loud, and that was one reason I decided to sell it. About 6 months ago I upgraded to an Anker power station (it's the Solix F2000 for anyone who's interested). It's got the all important Li-Po battery tech and a much more chunky 2048Why of capacity - (of which about 1700Wh is useable). I've coupled this with some solar powers and can now last almost indefinitely on free solar if I'm reasonably careful with what I use through the day. Overall I'd definitely recommend these things but they're not cheap - make sure you get a decent warranty - most of the big players are offering 5 years now as standard. I've not had any technical problems with either manufacturer though to be fair - hopefully it'll last me a long time!”

Best praise vs top criticism for EcoFlow DELTA Pro Ultra

+30 pts“I watched countless YouTube videos and read countless reviews about this market over the last two weeks and Ecoflow comes out on top basically every time. The only thing I’m not getting through Ecoflow is the panels and that’s because you can get a lot more for your money if you don’t go for foldable ones. I wish I would have bought on the last Amazon Prime sale, but I’m going to get the Delta Pro Ultra on Black Friday. I’m just some dude though, so what do I know.”

+1 pts“I might just need one F3800 with two expansion batteries, which provides 12kwh power to run my essential appliances. I just checked their website and found out they're around $6K. That looks reasonable. Bluetti ac500 and ecoflow delta pro might not in my lists cuz they cannot support 6000W, while delta pro ultra is too expensive. I need one can go up to 6000W and support high-voltage appliances like AC, fridge and my LG dryer.”
