These are calculated sensitivity cases, not a statistical confidence interval. Conservative uses lower efficiency and battery health, more reserve/temperature loss and higher load; optimistic changes these assumptions in the opposite direction.
Use this as a planning estimate, not a guaranteed runtime claim.
Unverified or missing specifications remain visible. The confidence label describes the station record, not a tested runtime or approval for emergency use.

13h 27m. Within the tracked power limits; compatibility still needs checking. Full-size refrigerator: 500 W · Duty cycle (%): 33% · Efficiency (%): 85% · Reserve kept unused (%): 15%. Runtime is conditional on successful startup, compatible voltage/connectors and sufficient output. Verify the actual device setup before relying on these hours.
This is an estimate. Real runtime changes with load, temperature, battery age, AC/DC output, and device behavior. Runtime is conditional on successful startup, compatible voltage/connectors and sufficient output. Verify the actual device setup before relying on these hours. These are calculated sensitivity cases, not a statistical confidence interval. Conservative uses lower efficiency and battery health, more reserve/temperature loss and higher load; optimistic changes these assumptions in the opposite direction.
