⚡ Power Math & Safety Analysis
The MARBERO Portable Power Station 88Wh delivers 80W of continuous power, which comfortably exceeds the Electric Knife Sharpener’s 30W operating draw. This gives you a 50W safety margin.
After accounting for 85% inverter efficiency, the usable capacity is 75Wh. Dividing this by the appliance’s power draw yields approximately 2.5 hours of continuous runtime.
Pro Tip
For cycling appliances, real-world runtime is longer. With a 1% duty cycle, expect 249.3 hours of elapsed time before depletion.
