⚡ Power Math & Safety Analysis
The EcoFlow DELTA Pro delivers 3600W of continuous power, which comfortably exceeds the Bench Grinder’s 400W operating draw. This gives you a 3200W safety margin.
After accounting for 85% inverter efficiency, the usable capacity is 3060Wh. Dividing this by the appliance’s power draw yields approximately 7.7 hours of continuous runtime.
Pro Tip
For cycling appliances, real-world runtime is longer. With a 20% duty cycle, expect 38.3 hours of elapsed time before depletion.
