⚡ Power Math & Safety Analysis
The EcoFlow River 3 Plus Extra Battery EB600 delivers 600W of continuous power, which comfortably exceeds the Cable TV Box’s 25W operating draw. This gives you a 575W safety margin.
After accounting for 85% inverter efficiency, the usable capacity is 486Wh. Dividing this by the appliance’s power draw yields approximately 19.4 hours of continuous runtime.
Pro Tip
For cycling appliances, real-world runtime is longer. With a 100% duty cycle, expect 19.4 hours of elapsed time before depletion.
