Best praise vs top criticism for EcoFlow RIVER 2 Max
Best Praise
+10 pts“LiPo (lithium polymer) batteries are old style Li-Ion cells and are dangerous batteries. The River 2 series uses LiFePO4 (also known as LFP) not only have a longer life, they don’t burst into flames when something goes wrong.”

+3 pts“Startup/Shutdown Amps on my Vevor DH, not quite 1 year old yet, requires around 12A. Make absolutely sure any power station you buy can output more than DC 10A because A LOT of them don't. My Ecoflow River2 Max does not output more than 10A so I can't use DC off of it to run my DH. I reverted to using a 30Ah LiFePO4 and it will run my DH just fine for about 7-8 hours at an outside ambient temp of 25f to a low of 17f, is what I experienced and the battery was around 20%. That was with settings where inside my tent was around 51f - 55f. I do have both solar and DC-DC charger but will be looking to upgrade to a LiFePO4 battery in the 200Ah range.”

+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”

+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.”
