Goal Zero Yeti 300 Wi-Fi router Runtime Estimate

A half-day router backup estimate for the Goal Zero Yeti 300. The estimate uses the same runtime engine as the main calculator and keeps source confidence visible.

Goal Zero Yeti 300 portable power station

Within the tracked power limits; compatibility still needs checking

Planning default · ≤ 19h 36m

AC inverter

Continuous output rating (W): 350 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.

  • Battery capacity (Wh): 296.96 Wh
  • Device wattage (W): 12 W
  • Duty cycle (%): 100%
  • Output path: AC inverter
  • Efficiency (%): 88%
  • Reserve kept unused (%): 10%
  • Battery health (%): 100%
  • Cold weather loss (%): 0%
  • Device startup surge (W): Not required
