How long will a BLUETTI AC180 run a refrigerator?
Estimated runtime: 12.6 h – 13.4 h
This estimate uses the BLUETTI AC180's published 1,152 Wh capacity, an assumed 85% inverter/conversion efficiency, and a typical refrigerator draw of 73–78 W.
⚠️ Compressor startup surge is not published in our sources. The BLUETTI AC180 lists 2,700 W surge; most fridges start well within that, but check your model.
The math
1,152 Wh × 0.85 = ~979 usable Wh. ÷ 78 W = 12.6 h; ÷ 73 W = 13.4 h.
Where the appliance wattage comes from
Average draw derived from DOE/EREC annual use of a frost-free 16–18 cu ft refrigerator (642–683 kWh/yr ÷ 8,760 h). Running/defrost nameplate wattage listed as 725 W; compressor startup surge can be higher and is not published.

For the most accurate number, check the watts on your appliance's label or measure it with a plug-in meter, then use the calculator.
