The EcoFlow DELTA 3 Max is a 2,048 Wh LiFePO4 power station at $879 with 2,400 W output, 4,800 W surge and 10 ms UPS switchover, checked November 9, 2026.
As of November 9, 2026 it costs about $0.43 per Wh. Among the 15 stations in our data with 1,900 to 2,200 Wh, the median is $859, or $0.42 per Wh, so it sits right at the middle. You pay for the 3 year warranty and the spec sheet, not for low cost. Wall charging is 1,800 W, solar input tops out at 500 W and weight is 44.8 lb.
The solar limit is the weak spot. The Pecron E2400LFP has the same 2,048 Wh and 2,400 W for $649, with up to 800 W of solar and 1,800 W wall charging. The Oukitel BP2000 Pro is $879 too, with 3,300 W, but only a 1 year warranty. For more output with the EcoFlow name, the EcoFlow DELTA 3 Max Plus is $1,149 for 3,000 W and 6,000 W surge.
Buy it for a 3 year warranty and a quick 10 ms UPS switch with 4,800 W surge. Skip it if you plan a big solar array or care most about cost.
