Answer
Can the EcoFlow RIVER 2 run BLACK+DECKER BDM05C 5,000 Btu/h window air conditioner?
Won't run
Won't run. 347 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 347 W.
How was the runtime calculated?
256 Wh × 0.85 = 218 Wh usable, divided by 347 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. ENERGY STAR lists 5,000 Btu/h, CEER 14.4, 115 V, variable-speed compressor, and 260.4 kWh/year. Rated input is 5,000 ÷ 14.4 = 347.2 W. That matches the listed annual energy at the DOE room-AC assumption of 750 hours (347.2 × 750 ÷ 1,000 = 260.4). The 347.2 W figure is the draw while cooling at the rated condition, not a whole-year average. Startup watts are not published.
