Best praise vs top criticism for EcoFlow RIVER 2 Pro
Best Praise
+10 pts“Literally just came out of a 5 day blackout due to an ice storm. We have the ecoflow river 2 pro and it was worth its weight in gold. We have a gas generator that we run twice a day for the fridge and freezer. We'd also do kettles if hot water for dishes and we would recharge our ecoflow then too. So why was it so great? We could power a kettle midday for coffee and tea without having to fire up the generator. It charged our phones, flashlights and my father in law's electric razor (just because he needed to shave). It powered the blower on our woodstove as the temperatures up here were still around freezing. And lastly we used it to power a crockpot to heat up food. It was absolutely amazing and fantastic for the in between times of running the generator. ”

Best praise vs top criticism for EcoFlow DELTA Pro Ultra
Best Praise
+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.”
