⚡ Power Math & Safety Analysis
The Jackery Explorer 300 delivers 300W of continuous power, which comfortably exceeds the 55-Inch Smart TV’s 120W operating draw. This gives you a 180W safety margin.
After accounting for 85% inverter efficiency, the usable capacity is 249Wh. Dividing this by the appliance’s power draw yields approximately 2.1 hours of continuous runtime.
Pro Tip
For cycling appliances, real-world runtime is longer. With a 100% duty cycle, expect 2.1 hours of elapsed time before depletion.
