How long will an Anker SOLIX F2000 (PowerHouse 767) run a refrigerator?

Will an Anker SOLIX F2000 (PowerHouse 767) run a fridge, and for how long?

About 29.0 hours on the base battery — calculated, not tested, with one caveat: the manufacturer publishes no surge rating for this model, so the compressor-start check could only use its continuous rating (2,300 W), which covers the fridge's draw while running. It depends on your fridge: a modern unit drawing 150 W while running, compressor on 40% of the time, is the load assumed here.

29.0 hours

Base battery (2,048 Wh), 150 W running draw at a 40% duty cycle, 0.85 AC efficiency. Continuous-run floor: 11.6 hours.

Start check: unverifiable, stated plainly. A fridge compressor can demand about 2,350 W at start (150 W + 2,200 W additional, Generac/Lowe's worksheet). The manufacturer publishes no surge rating for the Anker SOLIX F2000 (PowerHouse 767), so we cannot confirm it clears that spike — our calculators check it against the continuous rating only, and say so.

Load assumptions, graded: fridge running draw 150 W — the default in our fridge calculator, typical of a modern fridge while its compressor runs (check the label inside yours). Compressor duty cycle 40% — INFERRED, a WattLong planning assumption. Additional starting watts 2,200 W — Generac/Lowe's sizing worksheet, REPORTED (Generac's manual chart says 1,600 W; we use the higher figure). Runtime = capacity × 0.85 ÷ (150 W × 40%); the 0.85 factor is Bluetti's published formula factor, REPORTED. Base battery only — expansion batteries raise the hours in proportion. Generac's worksheet also lists a conservative 700 W sizing figure for older/larger fridges; sizing with it under-promises, which is the safe direction. Full methodology: how we calculate.

Food-safety note: a fridge keeps food safe for only a limited time without power, and runtime estimates are estimates. Follow USDA/FDA guidance on perishable food during outages.
