| Surge / Starting Power | 1400W | 900W | PASS (500W) |
| Battery Capacity | 448Wh total | ~120Wh/hr | 381Wh usable |
| Inverter Type | Pure Sine Wave | Pure Sine Recommended | ✅ Optimal |
| Duty Cycle | 100% (continuous) | 30% | 10.6 hrs real-world |
⚡ Power Math & Safety Analysis
The BLUETTI AC50B delivers 700W of continuous power, which comfortably exceeds the Upright Freezer’s 120W operating draw. This gives you a 580W safety margin.
After accounting for 85% inverter efficiency, the usable capacity is 381Wh. Dividing this by the appliance’s power draw yields approximately 3.2 hours of continuous runtime.
Pro Tip
For cycling appliances, real-world runtime is longer. With a 30% duty cycle, expect 10.6 hours of elapsed time before depletion.
