What watts were compared?
Station continuous output is 1,800 W. No motor-surge rating is applied. Appliance running draw is 1,116 W.
How was the runtime calculated?
1,024 Wh × 0.85 = 870 Wh usable, divided by 1,116 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. Zoeller lists the Model 53 at 3/10 HP, 115 V or 230 V, and 4.8–9.7 A. The 115 V automatic model in Zoeller's 50-series technical table is 9.7 A. Running watts used here are 9.7 × 115 = 1,115.5 W. Startup amps are not published. How often the float runs is site-specific, so no duty cycle is stored.
