EcoFlow DELTA 3 1500 Wi-Fi router Runtime Estimate
A four-day router backup planning estimate for the EcoFlow DELTA 3 1500. The estimate uses the same runtime engine as the main calculator and keeps source confidence visible.
meets this planning target
96-hour planning target.
AC inverter
Output path with 1800 W tracked output limit.
This estimate assumes 12 W running draw, 100% duty cycle, 88% efficiency, and 10% reserve.
Runtime Range

Assumptions
These are calculation inputs, not lab-tested runtime claims.
- 1536 Wh nominal battery capacity
- AC inverter output path
- 88% conversion efficiency
- 10% reserve kept unused
- 12 W average load from 1 load
- 100% battery health
- 0% temperature loss
- Fixed station overhead unknown; not included
- This is an estimate. Real runtime changes with load, temperature, battery age, AC/DC output, and device behavior.

FAQ
Short answers for this model and device pair.
How long will EcoFlow DELTA 3 1500 run wi-fi router?
Using the current assumptions, the estimate is 4d 5h. 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.
