YES — Fully Compatible
This power station can reliably run your appliance.
The EcoFlow DELTA 3 Plus is fully compatible with a CPAP Machine. It delivers 1800W of continuous power, giving you a 1770W safety margin over the 30W draw. Under typical conditions, expect around 43.5 hours of uninterrupted runtime, or approximately 43.5 hours with real-world duty cycle factored in.

⚡ Power Math & Safety Analysis
The EcoFlow DELTA 3 Plus delivers 1800W of continuous power, which comfortably exceeds the CPAP Machine’s 30W operating draw. This gives you a 1770W safety margin.
After accounting for 85% inverter efficiency, the usable capacity is 1306Wh. Dividing this by the appliance’s power draw yields approximately 43.5 hours of continuous runtime.
Pro Tip
For cycling appliances, real-world runtime is longer. With a 100% duty cycle, expect 43.5 hours of elapsed time before depletion.
