How long will a BLUETTI AC70 run a laptop?
Estimated runtime: 13.1 h
This estimate uses the BLUETTI AC70's published 768 Wh capacity, an assumed 85% inverter/conversion efficiency, and a typical laptop draw of 50–50 W.
The math
768 Wh × 0.85 = ~653 usable Wh. ÷ 50 W = 13.1 h.
Where the appliance wattage comes from
DOE typical wattage table lists a laptop at 50 W. Many modern laptops draw less when idle.
