How long will a BLUETTI AC70 run a ceiling fan?
Estimated runtime: 3.7 h – 10.0 h
This estimate uses the BLUETTI AC70's published 768 Wh capacity, an assumed 85% inverter/conversion efficiency, and a typical ceiling fan draw of 65–175 W.
The math
768 Wh × 0.85 = ~653 usable Wh. ÷ 175 W = 3.7 h; ÷ 65 W = 10.0 h.
Where the appliance wattage comes from
