Our answer
On our planning profile the Anker SOLIX F3000 runs a box fan for about 41 hours, or 32 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 box fan runs on 120V and the Anker SOLIX F3000 supplies 120V AC. |
| Continuous output | Clears | A 60W running load sits inside the 3,600W continuous rating, leaving about 5900% headroom. |
| Startup demand | Clears | The 120W start is covered by continuous output alone, so no surge rating is needed. |
| Inverter self-consumption | Unverified | This is a long, low-power load, so the inverter's own draw materially changes the answer. That figure is not published for this station. |
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 60W, which applies a 100% duty cycle to a 60W running draw. Holding back a 20% reserve for battery age, cold, and a longer outage leaves 32 hours. These are calculations, not measurements from a test.
What we could not verify
These gaps are in the published evidence, not in the arithmetic. Each one is a reason to check before you depend on this pairing.
- Inverter self-consumption is not published, and it matters more than the appliance load on a run this long.
Replace our assumptions with your own
Fan speed is the whole story. Running a box fan on low instead of high can roughly halve the energy it uses over a night.
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.
