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. ”

+7 pts“Ya I watched this video of him running the delta pro with solar and he showed how long it would run his fridge on solar only solar good video”

ViewTop Criticism
+1 pts“I've been looking at doing exactly what you describe: 2 Anker F3800+'s with the dual hub connector can provide up to 12KW same as your generator. 2 Ecoflow Delta Pro 3's can be similarly combined for 8KW. Costco had a sale for the 2 units for $4200 that just ended. Ecoflow looks cheaper, but their support from China is worse... firmware updates can turn the system into a brick. Ecoflow also advertises you describe with their smart generator started/stopped by the battery... they claim something like a 40% increase in efficiency by letting the generator run at peak performance. Your idea also lets you use a much smaller generator as you only need to supply the average load vs. the peak loads. It's also a lot quieter when only running the generator to top off the batts... probably won't run at all over night.”
