How long will a EcoFlow RIVER 3 Plus run a laptop?
Estimated runtime: 4.9 h
This estimate uses the EcoFlow RIVER 3 Plus's published 286 Wh capacity, an assumed 85% inverter/conversion efficiency, and a typical laptop draw of 50–50 W.
The math
286 Wh × 0.85 = ~243 usable Wh. ÷ 50 W = 4.9 h.
Where the appliance wattage comes from
DOE typical wattage table lists a laptop at 50 W. Many modern laptops draw less when idle.
