Questions
How do the EcoFlow DELTA 3 Plus and the EcoFlow DELTA 2 compare?
EcoFlow DELTA 3 Plus and EcoFlow DELTA 2 publish the same capacity and continuous output, so the useful differences are chemistry, surge, weight, and ports.
Which one runs longer?
EcoFlow DELTA 3 Plus has 870 Wh usable in Willrun's math (1,024 Wh × 0.85). EcoFlow DELTA 2 has 870 Wh usable. Runtime still depends on the appliance's average draw.
Can cycle life be ranked between them?
The cycle quotes do not share a published endpoint, or one of them is missing. Willrun does not rank 70% retention against 80% retention.
Where do the numbers come from?
US spec table: 1,024 Wh, 6 outlets, 1,800 W (surge 3,600 W), X-Boost 2,200 W, about 12.5 kg (27.6 lb), LFP, 4,000 cycles to 80%+. US product page: about 1 kWh, 1,800 W output, X-Boost up to 2,200 W, LiFePO4, 3,000+ cycles. Weight, size, and the 4 AC outlets are from the EcoFlow DELTA 2 user manual. The manual line that pairs 1,800 W with a 2,700 W surge is printed next to 230 V, so that surge is not used for this 120 V entry.
