⚡ Power Math & Safety Analysis
The Westinghouse 5000 Peak Watt Super Quiet Portable Inverter Generator delivers 3900W of continuous power, which comfortably exceeds the Angle Grinder 4.5 Inch’s 900W operating draw. This gives you a 3000W safety margin.
After accounting for 85% inverter efficiency, the usable capacity is 16150Wh. Dividing this by the appliance’s power draw yields approximately 17.9 hours of continuous runtime.
Pro Tip
For cycling appliances, real-world runtime is longer. With a 20% duty cycle, expect 89.7 hours of elapsed time before depletion.
