Questions
How do the EcoFlow DELTA 2 and the BLUETTI AC180 compare?
BLUETTI AC180 stores more energy (1,152 Wh).
Which one runs longer?
EcoFlow DELTA 2 has 870 Wh usable in Willrun's math (1,024 Wh × 0.85). BLUETTI AC180 has 979 Wh usable. Runtime still depends on the appliance's average draw.
Can cycle life be ranked between them?
Both quotes are to 80%, so the cycle counts can be read side by side. A lab test is still not the same as a year in a garage.
Where do the numbers come from?
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. Spec table: 1,152 Wh, 4×120 V at 1,800 W, surge listed as 2,700 W, about 35.27 lb, LiFePO4, 3,500+ cycles. The FAQ defines Power Lifting as 2,700 W for heaters, hair dryers, kettles, and blankets, and says not to run an air conditioner or washing machine. Willrun therefore does not treat 2,700 W as motor-start capacity.
