4d 4h
Estimated runtime: Wi-Fi router. Within the tracked power limits; compatibility still needs checking
A long router backup estimate for the Goal Zero Yeti 1500X with reserve included. The estimate uses the same runtime engine as the main calculator and keeps source confidence visible.

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.

4d 4h. Within the tracked power limits; compatibility still needs checking. Wi-Fi router: 12 W · Duty cycle (%): 100% · Efficiency (%): 88% · Reserve kept unused (%): 10%. 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.
