What Redditors Say
Best praise vs top criticism for EcoFlow DELTA Max
Best Praise
+1 pts“I bought a cheapo off Amazon to see how it would work for me. I use it to run my cpap when I’m camping and can get about 2 solid nights of use. I really loved the design of the ecoflo and recently upgraded. To the delta max. It’s not cheap but I would recommend. I bought a refurbished unit on a major sale. I have some portable bi facial panels but usually just charge on a wall outlet right now. They make a great little unit to charge that installs in your vehicle. I have the ability to expand and add more batteries. My buddy just got the Anker Solix and we will be testing that this weekend.”

Best praise vs top criticism for EcoFlow RIVER 2 Pro
Best Praise
+7 pts“I have found my Ecoflow unit to be a good value for short outages, limited load situations. (I have a River 2 Pro) It runs my fridge for 8+ hours, and easily charges all our portable electronics many many times. I pull it out long before I even consider starting the generator. They seem to make good stuff.”
