Best praise vs top criticism for EcoFlow DELTA Pro
Best Praise
+23 pts“What you want is cost prohibitive. Running 1500 watts for 8 hours of the day demands 12kwh. You’re looking at something like an ecoflow delta pro ultra + battery for $7500 just for one day of 30% uptime. It would be amazing to have a box that fits in an apartment and can power appliances cheaply, but that doesn’t exist yet.”

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.”
