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 |

Estimated runtime
42mEstimated runtime: 42mThis 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.

Rated Wh is reduced by efficiency, reserve, battery health, and temperature before it is divided by average load.

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.
- Tracked solar input is 36 W before panel, weather, angle, and controller losses.
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.
- Confidence is not marked verified; keep the linked source context visible before making a purchase or emergency plan.
