⚡ Power Math & Safety Analysis
The EcoFlow DELTA 3 Plus delivers 1800W of continuous power, which comfortably exceeds the 5L Oxygen Concentrator’s 300W operating draw. This gives you a 1500W safety margin.
After accounting for 85% inverter efficiency, the usable capacity is 1306Wh. Dividing this by the appliance’s power draw yields approximately 4.4 hours of continuous runtime.
Pro Tip
For cycling appliances, real-world runtime is longer. With a 80% duty cycle, expect 5.4 hours of elapsed time before depletion.
