AC inverter
Continuous output rating (W): 600 W
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.
Runtime range
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.
