Runtime evidence · sourced load
Yes. 48 sourced stations in our current catalog clear the capacity and inverter checks for this load.
01 · Runtime ladder
Nominal capacity × depth of discharge × inverter efficiency ÷ sourced average draw.
| Capacity class | Estimated runtime | Evidence |
|---|---|---|
| 300 Whstep 1 | 11.5 hr | Portable fan (10-inch) load · 2026-07-06 |
| 500 Whstep 2 | 19.1 hr | Portable fan (10-inch) load · 2026-07-06 |
| 1,000 Whstep 3 | 38.3 hr | Portable fan (10-inch) load · 2026-07-06 |
| 2,000 Whstep 4 | 76.5 hr | Portable fan (10-inch) load · 2026-07-06 |
These are comparison projections, not a promise. Temperature, inverter behavior, cycling, and the individual station's measured delivered capacity can change real runtime.
