Best praise vs top criticism for EcoFlow RIVER 3
Best Praise
+3 pts“Was just going to post this. Plug it in the wall then plug in the computer or TV or whatever. It will always be ready. Have a number of them. The Ecoflow River 3 line is quite impressive for charging those devices.”

ViewTop Criticism
+2 pts“I have the EcoFlow River 3. It is great for running an LED light or two during a power outage. However, charging a couple phones and tablets knocked the battery down significantly. River was dead after second charging of all devices. I feel you will be greatly disappointed in its performance running those appliances on it.”

Best praise vs top criticism for Generac Guardian Series
Best Praise
+14 pts“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”
r/preppers
ViewTop Criticism
+81 pts“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.”
