YES — Fully Compatible
This power station can reliably run your appliance.
The BLUETTI AC50B is fully compatible with a CPAP with Heated Humidifier. It delivers 700W of continuous power, giving you a 640W safety margin over the 60W draw. Under typical conditions, expect around 6.3 hours of uninterrupted runtime, or approximately 6.3 hours with real-world duty cycle factored in.

| Battery Capacity | 448Wh total | ~60Wh/hr | 381Wh usable |
| Inverter Type | Pure Sine Wave | Pure Sine Recommended | ✅ Optimal |
| Duty Cycle | 100% (continuous) | 100% | 6.3 hrs real-world |
⚡ Power Math & Safety Analysis
The BLUETTI AC50B delivers 700W of continuous power, which comfortably exceeds the CPAP with Heated Humidifier’s 60W operating draw. This gives you a 640W safety margin.
After accounting for 85% inverter efficiency, the usable capacity is 381Wh. Dividing this by the appliance’s power draw yields approximately 6.3 hours of continuous runtime.
Pro Tip
For cycling appliances, real-world runtime is longer. With a 100% duty cycle, expect 6.3 hours of elapsed time before depletion.
