Jackery Explorer 300 Plus Refrigerator Runtime Estimate

A compact Jackery refrigerator check where AC output and compressor surge are the limiting questions. The estimate uses the same runtime engine as the main calculator and keeps source confidence visible.

Exceeds a tracked power limit — do not rely on these hours

AC inverter

Continuous output rating (W): 300 W

Full-size refrigerator: 500 W · Duty cycle (%): 33% · Efficiency (%): 85% · 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): 288 Wh
  • Device wattage (W): 500 W
  • Duty cycle (%): 33%
  • Output path: AC inverter
  • Efficiency (%): 85%
  • Reserve kept unused (%): 10%
  • Battery health (%): 100%
  • Cold weather loss (%): 0%
  • Device startup surge (W): 2,900 W
  • 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.
  • Exceeds a tracked power limit — do not rely on these hours
  • The combined running load (500 W) is above the selected station continuous output (300 W).
  • The largest startup surge (2,900 W) is above the selected station surge rating (600 W).
