⚡ Power Math & Safety Analysis
The EcoFlow River 3 Plus Extra Battery EB600 delivers 600W of continuous power, which comfortably exceeds the External Hard Drive’s 10W operating draw. This gives you a 590W safety margin.
After accounting for 85% inverter efficiency, the usable capacity is 486Wh. Dividing this by the appliance’s power draw yields approximately 48.6 hours of continuous runtime.
Pro Tip
For cycling appliances, real-world runtime is longer. With a 30% duty cycle, expect 162.1 hours of elapsed time before depletion.
