Our answer
On our planning profile the Anker SOLIX F3000 runs a household refrigerator for about 47 hours, or 38 hours if you keep a reserve back.
The checks behind this answer
Stored energy is the final check, not the first. Voltage, continuous output, and startup demand must clear before runtime means anything. Missing published evidence stays marked unverified instead of being treated as a pass.
| Check | Result | Why |
|---|---|---|
| Voltage | Clears | A household refrigerator runs on 120V and the Anker SOLIX F3000 supplies 120V AC. |
| Continuous output | Clears | A 150W running load sits inside the 3,600W continuous rating, leaving about 2300% headroom. |
| Startup demand | Clears | The 1,200W start is covered by continuous output alone, so no surge rating is needed. |
How the number is built
A battery holds back some of its rated capacity, and converting to household AC costs more on top. Of the 3,072Wh rated here, roughly 2,433Wh reaches the outlet under a conservative planning model.
That energy meets an average load of 51.5W, which applies a 33% duty cycle to a 150W running draw. Holding back a 20% reserve for battery age, cold, and a longer outage leaves 38 hours. These are calculations, not measurements from a test.
Before you rely on this
These limits decide whether this appliance belongs on a portable battery at all.
- A closed refrigerator keeps food safe for about four hours without power. Backup power can extend that, but the temperature still needs checking.
Replace our assumptions with your own
Room temperature, how often the door opens, how full the refrigerator is, the age of the door seals, and whether an automatic defrost cycle falls inside the outage all move the daily energy figure more than the model name does.
Read the nameplate or data label for voltage and rated amps or watts, then run the appliance through a normal cycle on a plug-in energy meter for 24 hours. Use the measured watt-hours in the calculator instead of the default on this page.
