Runtime Starting Points
These are formula estimates using the tracked capacity, a 10% reserve, and each scenario's default wattage and duty cycle. They are planning starters, not measured runtimes.
| Scenario | Default load | Estimate | Scenario confidence | Station page |
|---|---|---|---|---|
| Full-size refrigerator | 500 W at 33% | AC output unknown | Estimated | Use calculator |
| CPAP without heated humidifier | 40 W at 100% | AC output unknown | Estimated | Use calculator |
| Starlink Mini | 32 W at 100% | AC output unknown | Estimated | Use calculator |
| Wi-Fi router | 12 W at 100% | AC output unknown | Estimated | Use calculator |

Estimated runtime
1h 10mEstimated runtime: 1h 10mThis setup is tight. Reduce load, use DC where possible, or choose a larger station.
Conservative assumes harder conditions; optimistic assumes favorable conditions.
- This is an estimate. Real runtime changes with load, temperature, battery age, AC/DC output, and device behavior.
- The selected station output rating is unknown, so running-load compatibility is not verified.
- Usable energy

- Average load
- 60 W
- Fixed station overhead

Rated Wh is reduced by efficiency, reserve, battery health, and temperature before it is divided by average load.
- Rated battery
- 91 Wh
- Battery capacity (Wh): 91 Wh
- Usable energy
- 70 Wh
- 91 Wh x 85% x 90% x 100% x 100%
- Average load
- 60 W
- 60 W running, 60 W average after duty cycle and quantity
- Fixed station overhead
- Unknown (not included)
- 60 W / 85% = 70.6 W battery draw; fixed overhead is unknown and excluded
- Estimated runtime
- 1h 10m
- 70 Wh / 60 W = 1h 10m
- 91 Wh nominal battery capacity
- AC inverter output path
- 85% conversion efficiency
- 10% reserve kept unused
- 60 W average load from 1 load
- 100% battery health
- 0% temperature loss
- Fixed station overhead unknown; not included

Good fit when
- Capacity is a compact class; use it for small electronics and short essentials rather than high-wattage appliances.
- AC output is unknown in the current source record, so do not assume it can run AC appliances.
- USB-C output is tracked at laptop-class power, useful for direct DC charging when the device supports it.
Watch out for
- Surge output is unknown, so do not assume compressor, pump, or power-tool startup will work.
- Still unknown in the source-backed record: ac output, surge output.
