4h 58m
Estimated runtime for full-size refrigerator.
Model by device runtime
A common home-backup question for a 1kWh-class Jackery station. The estimate uses the same runtime engine as the main calculator and keeps source confidence visible.

Estimated runtime for full-size refrigerator.
8-hour planning target.
Output path with 1500 W tracked output limit.
Use the range to plan around temperature, battery condition, and measurement uncertainty.
These are calculation inputs, not lab-tested runtime claims.
Station facts and scenario wattage notes stay separated so the estimate is easier to audit.
Station: Verified. Scenario: Estimated. Last station verification: 2026-06-24.
These computed checks show how reserve, battery health, and temperature assumptions move the estimate before you trust one number.
4h 58m
10% reserve, 100% battery health, 0% temperature loss.
4h 25m
20% reserve, 100% battery health, 0% temperature loss.
3h 48m
10% reserve, 90% battery health, 15% temperature loss.

Short answers for this model and device pair.
Using the current assumptions, the estimate is 4h 58m. Real runtime depends on device settings, output path, temperature, battery age, and measured wattage.
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.
