What watts were compared?
Station continuous output is 1,800 W. No motor-surge rating is applied. Appliance running draw is 533 W.
How was the runtime calculated?
1,024 Wh × 0.85 = 870 Wh usable, divided by 533 W average draw.
Where did 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. ENERGY STAR lists 8,000 Btu/h, CEER 15, 115 V, variable-speed compressor, and 400 kWh/year. Rated input is 8,000 ÷ 15 = 533.3 W, which matches 400 kWh at 750 hours. Startup watts are not published.
