Runtime evidence · sourced load
Power tools draw 1,800 W while running. 6 stations clear the capacity, inverter, and startup checks at that load.
01 · Runtime ladder
Nominal capacity × depth of discharge × inverter efficiency ÷ sourced average draw.
| Capacity class | Estimated runtime | Evidence |
|---|---|---|
| 300 Whstep 1 | 0.1 hr | Circular saw, 15A (while cutting) load · 2026-07-20 |
| 500 Whstep 2 | 0.2 hr | Circular saw, 15A (while cutting) load · 2026-07-20 |
| 1,000 Whstep 3 | 0.4 hr | Circular saw, 15A (while cutting) load · 2026-07-20 |
| 2,000 Whstep 4 | 0.9 hr | Circular saw, 15A (while cutting) load · 2026-07-20 |
These are comparison projections, not a promise. Temperature, inverter behavior, cycling, and the individual station's measured delivered capacity can change real runtime.

Output-capable fit
Why it fits
5,400 W above the plan's running load (7,200 W continuous output)
Main compromise
4,800 W below the highest output reserve across 6 eligible models
Best all-round reserve
Why it fits
79.7 BatteryRank score — the highest of any station that fits this plan
Main compromise
84 kg heavier than the lightest eligible model (5 of 6 eligible models have this sourced value)
Extended reserve
Why it fits
34.8 projected runtime hours
Main compromise
34.8 hours less projected runtime than the longest-running eligible model across 6 eligible models
