YES — Fully Compatible
This power station can reliably run your appliance.
The BLUETTI AC70 is fully compatible with a CPAP with Heated Humidifier. It delivers 1000W of continuous power, giving you a 940W safety margin over the 60W draw. Under typical conditions, expect around 10.9 hours of uninterrupted runtime, or approximately 10.9 hours with real-world duty cycle factored in.

| Battery Capacity | 768Wh total | ~60Wh/hr | 653Wh usable |
| Inverter Type | Pure Sine Wave | Pure Sine Recommended | ✅ Optimal |
| Duty Cycle | 100% (continuous) | 100% | 10.9 hrs real-world |
⚡ Power Math & Safety Analysis
The BLUETTI AC70 delivers 1000W of continuous power, which comfortably exceeds the CPAP with Heated Humidifier’s 60W operating draw. This gives you a 940W safety margin.
After accounting for 85% inverter efficiency, the usable capacity is 653Wh. Dividing this by the appliance’s power draw yields approximately 10.9 hours of continuous runtime.
Pro Tip
For cycling appliances, real-world runtime is longer. With a 100% duty cycle, expect 10.9 hours of elapsed time before depletion.
