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. ”
