Can an EcoFlow RIVER 3 run a well pump (1/2 hp)?
No — the EcoFlow RIVER 3 can't run a well pump (1/2 hp).
The well pump (1/2 hp) draws about 1,000 W running, with a 2,100 W startup surge; the RIVER 3 delivers 300 W continuous and 600 W surge. That's not enough continuous output.

Common questions
Can the EcoFlow RIVER 3 run a well pump (1/2 hp)?
No. A well pump (1/2 hp) needs 1,000 W continuous and a 2,100 W startup surge, but the EcoFlow RIVER 3 only delivers 300 W continuous and a 600 W surge — so it can’t sustain the running load. You'd want a larger unit.
