How long will a EcoFlow RIVER 3 Plus run a flat-screen tv?
Estimated runtime: 1.8 h – 2.2 h
This estimate uses the EcoFlow RIVER 3 Plus's published 286 Wh capacity, an assumed 85% inverter/conversion efficiency, and a typical flat-screen tv draw of 110–133 W.
The math
286 Wh × 0.85 = ~243 usable Wh. ÷ 133 W = 1.8 h; ÷ 110 W = 2.2 h.
Where the appliance wattage comes from
DOE typical wattage table: flat screen 120 W, 19-inch 65–110 W, 36-inch 133 W. We use 110–133 W.
