| Battery Capacity | 293Wh total | ~2Wh/hr | 249Wh usable |
| Inverter Type | Pure Sine Wave | Pure Sine Recommended | ✅ Optimal |
| Duty Cycle | 100% (continuous) | 100% | 124.5 hrs real-world |
⚡ Power Math & Safety Analysis
The Jackery Explorer 300 delivers 300W of continuous power, which comfortably exceeds the Pulse Oximeter’s 2W operating draw. This gives you a 298W safety margin.
After accounting for 85% inverter efficiency, the usable capacity is 249Wh. Dividing this by the appliance’s power draw yields approximately 124.5 hours of continuous runtime.
Pro Tip
For cycling appliances, real-world runtime is longer. With a 100% duty cycle, expect 124.5 hours of elapsed time before depletion.
