EcoFlow RIVER 3 Wi-Fi router Runtime Estimate

A half-day router backup estimate for the compact EcoFlow RIVER 3. The estimate uses the same runtime engine as the main calculator and keeps source confidence visible.

EcoFlow RIVER 3 portable power station

Within the tracked power limits; compatibility still needs checking

Planning default · ≤ 16h 10m

AC inverter

Continuous output rating (W): 300 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.

Assumptions

Use this as a planning estimate, not a guaranteed runtime claim.

  • Battery capacity (Wh): 245 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
  • Fixed station overhead unknown; not included
  • 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.
