How long will a EcoFlow DELTA 3 run a laptop?
Estimated runtime: 17.4 h
This estimate uses the EcoFlow DELTA 3's published 1,024 Wh capacity, an assumed 85% inverter/conversion efficiency, and a typical laptop draw of 50–50 W.
The math
1,024 Wh × 0.85 = ~870 usable Wh. ÷ 50 W = 17.4 h.
Where the appliance wattage comes from
DOE typical wattage table lists a laptop at 50 W. Many modern laptops draw less when idle.
