Runtime evidence · sourced load
A Wi-Fi router draws 18 W while running. 63 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 | 12.8 hr | Wi-Fi router + modem load · 2026-07-06 |
| 500 Whstep 2 | 21.3 hr | Wi-Fi router + modem load · 2026-07-06 |
| 1,000 Whstep 3 | 42.5 hr | Wi-Fi router + modem load · 2026-07-06 |
| 2,000 Whstep 4 | 85 hr | Wi-Fi router + modem 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.

Easy-carry fit
Why it fits
7.8 kg, 7.2 kg below the 15 kg preferred limit
Main compromise
1.4 kg heavier than the lightest eligible model (62 of 63 eligible models have this sourced value)
Best all-round fit
Why it fits
72 BatteryRank score — the highest of any station that fits this plan
Main compromise
7.7 points below the highest-scoring eligible model (62 of 63 eligible models have this sourced value)
Extended runtime
Why it fits
96.7 projected runtime hours
Main compromise
483.6 hours less projected runtime than the longest-running eligible model across 63 eligible models
