How long will the EcoFlow River 3 run a gaming monitor (27")?

Will the EcoFlow River 3 run a gaming monitor (27")?

Yes — the River 3 runs a gaming monitor (27") comfortably

Its 300W continuous output easily covers the 35W draw.

Estimated runtime
about 5 hours
on a single full charge
Est. usable (AC): 188 Wh
Appliance draw: 35 W
Continuous output: 300 W

How we calculated this

We start from the EcoFlow River 3's 188 Wh of estimated usable energy at the outlet — its 245 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the gaming monitor (27")'s 35W draw:

188 Wh ÷ 35 W ≈ 5.4 hours

Real-world runtime varies with temperature, cable losses, and how hard the appliance actually cycles. Treat this as a solid estimate, not a guarantee.
