1-hour planning target.
AC inverter
Output path with 300 W tracked output limit.
This estimate assumes 500 W running draw, 33% duty cycle, 85% efficiency, and 10% reserve.
Runtime Range
Use the range to plan around temperature, battery condition, and measurement uncertainty.

Assumptions
These are calculation inputs, not lab-tested runtime claims.
- 245 Wh nominal battery capacity
- AC inverter output path
- 85% conversion efficiency
- 10% reserve kept unused
- 165 W average load from 1 load
- 100% battery health
- 0% temperature loss
- This is an estimate. Real runtime changes with load, temperature, battery age, AC/DC output, and device behavior.
- The combined running load (500 W) is above the selected station continuous output (300 W).
- The combined running load is above 80% of the station rating. Leave headroom for heat, altitude, and measurement error.

FAQ
Short answers for this model and device pair.
How long will EcoFlow RIVER 3 run full-size refrigerator?
Using the current assumptions, the estimate is 1h 8m. Real runtime depends on device settings, output path, temperature, battery age, and measured wattage.
Is this a guaranteed runtime?
No. It is a planning estimate from source-linked station specs and scenario wattage assumptions. Use a watt meter and manufacturer guidance for critical backup planning.
