Can an EcoFlow RIVER 3 run an oxygen concentrator?

No — the EcoFlow RIVER 3 can't run an oxygen concentrator.
The oxygen concentrator draws about 350 W running, with a 600 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 an oxygen concentrator?

No. An oxygen concentrator needs 350 W continuous, but the EcoFlow RIVER 3 only delivers 300 W continuous — so it can’t sustain the running load. You'd want a larger unit.
