Best praise vs top criticism for EcoFlow RIVER 2 Pro
“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. ”
“I tried EcoFlow (River 2 Pro) - twice. And each time if failed, miserably. Each one bricked and I asked for my money back (and got it after a lot of back and forth).”
What Redditors Say
Best praise vs top criticism for Generac Guardian Series
“I've installed hundreds of generacs. I've had one with a bad board and it wouldn't go into auto, and one that idled more like a Briggs and Stratton unit than a generac (rough and unstable). We have units from 17 years ago still running with yearly maintenance and happy owners”
“Long story short: He had a Generac Home Generator installed about a month ago. However, since it was installed, it has yet to work. Been DOA, dead on arrival, and he had to go through the Hurricane without it. He and others are claiming that this isn't just a "one off" and that Generac is putting out poor quality generators then what they used to.”
