If you own a DELTA 2
Its user manual gives 1,024 Wh of LiFePO4 cells rated 4,000 cycles to 80%, AC outlets sharing 1,800 W (2,700 W surge), 1,200 W wall charging and 500 W of solar input. It takes one Smart Extra Battery. To see what it runs, enter 1,024 Wh in the watt-hour calculator: the same capacity as the DELTA 3, so the DELTA 3's runtime table applies to it as well.
A full-size refrigerator averaging 41 W runs about 21 hours on a full DELTA 2, by the calculator's 85% allowance for inverter losses.

Questions buyers ask
Is the EcoFlow DELTA 2 discontinued?
EcoFlow's US store no longer lists it: on Oct 11, 2026 its DELTA 2 page opened the DELTA 3 instead, and the store's search showed only the DELTA 2 Max. The DELTA 3 keeps the DELTA 2's 1,024 Wh and 1,800 W.
What changed from the DELTA 2 to the DELTA 3?
By the two makers' sheets: surge from 2,700 W to 3,600 W, wall charging from 1,200 W to 1,500 W, and a stated UPS switchover under 10 ms, which the DELTA 2's manual does not give. Capacity, continuous output and the 500 W solar input are the same.
Is the DELTA 2 Max the same as the DELTA 2?
No. The DELTA 2 Max holds 2,048 Wh, twice as much, gives 2,400 W and weighs 50 lb against the DELTA 2's 27 lb. EcoFlow still sells it at $1,029 at EcoFlow, checked Oct 11, 2026.
