Will the EcoFlow River 3 run a wi-fi router / modem?
Yes — the River 3 runs a wi-fi router / modem comfortably
Its 300W continuous output easily covers the 15W draw.
Estimated runtime
about 13 hours
on a single full charge
Est. usable (AC): 188 Wh
Appliance draw: 15 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 wi-fi router / modem's 15W draw:
188 Wh ÷ 15 W ≈ 12.5 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.
