| Duty Cycle | 100% (continuous) | 50% | 24.9 hrs real-world |
⚡ Power Math & Safety Analysis
The Jackery Explorer 300 delivers 300W of continuous power, which comfortably exceeds the Insulin Cooler Fridge’s 20W operating draw. This gives you a 280W safety margin.
After accounting for 85% inverter efficiency, the usable capacity is 249Wh. Dividing this by the appliance’s power draw yields approximately 12.5 hours of continuous runtime.
Pro Tip
For cycling appliances, real-world runtime is longer. With a 50% duty cycle, expect 24.9 hours of elapsed time before depletion.
