| Battery Capacity | 768Wh total | ~400Wh/hr | 653Wh usable |
| Inverter Type | Pure Sine Wave | Pure Sine Recommended | ✅ Optimal |
| Duty Cycle | 100% (continuous) | 20% | 8.2 hrs real-world |
⚡ Power Math & Safety Analysis
The BLUETTI AC70 delivers 1000W of continuous power, which comfortably exceeds the Bench Grinder’s 400W operating draw. This gives you a 600W safety margin.
After accounting for 85% inverter efficiency, the usable capacity is 653Wh. Dividing this by the appliance’s power draw yields approximately 1.6 hours of continuous runtime.
Pro Tip
For cycling appliances, real-world runtime is longer. With a 20% duty cycle, expect 8.2 hours of elapsed time before depletion.
