Can an EcoFlow RIVER 2 run a window ac (8,000 btu)?

Q: Can the EcoFlow RIVER 2 run a window ac (8,000 btu)?

No. A window ac (8,000 btu) needs 715 W continuous and a 1,250 W startup surge, but the EcoFlow RIVER 2 only delivers 300 W continuous and a 600 W surge — so it can’t sustain the running load. You'd want a larger unit.
