Answer
Can the EcoFlow RIVER 2 run Zoeller Model 53 3/10 HP sump pump, 115 V?
Won't run
Won't run. 1,116 W is above the 300 W continuous output, and it is outside the 600 W X-Boost that Willrun will apply to simple heaters. Estimated runtime: no runtime, because it will not stay on.

What watts were compared?
Station continuous output is 300 W. No motor-surge rating is applied. Appliance running draw is 1,116 W.
How was the runtime calculated?
256 Wh × 0.85 = 218 Wh usable, divided by 1,116 W average draw.
Where did the numbers come from?
US/CA comparison table: 256 Wh, 2 AC outlets at 300 W, X-Boost 600 W, 7.7 lb, LiFePO4, 3,000 cycles to 80%+. EcoFlow describes the 600 W figure as surge with X-Boost. Willrun treats it as a resistive boost, not motor-start capacity. The manual language for X-Boost says it suits heating devices. 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.
