Anker SOLIX C300 Refrigerator Runtime Estimate
A compact Anker refrigerator check with SurgePad caveats and compressor cycling visible. The estimate uses the same runtime engine as the main calculator and keeps source confidence visible.
meets this planning target
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.
- 288 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
- Fixed station overhead unknown; not included
- 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.
- The largest startup surge (2900 W) is above the selected station surge rating (600 W).

FAQ
Short answers for this model and device pair.
How long will Anker SOLIX C300 run full-size refrigerator?
Using the current assumptions, the estimate is 1h 20m. 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.
