What Redditors Say
Best praise vs top criticism for EcoFlow DELTA Max
“check out ecoflow, I used one of the more expensive models to run the refrigerator and a portable ac unit after the hurricane. You can charge them with solar panels.”
“Back to back snow storms both being blizzards is pretty crazy. I lost power for a little over an hour this morning and of course my Ecoflow that I normally dedicate to the refrigerator was off getting its warranty tested.”
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.”
