⚡ Power Math & Safety Analysis
The EcoFlow DELTA 3 Plus delivers 1800W of continuous power, which comfortably exceeds the Portable Shower Heater’s 350W operating draw. This gives you a 1450W safety margin.
After accounting for 85% inverter efficiency, the usable capacity is 1306Wh. Dividing this by the appliance’s power draw yields approximately 3.7 hours of continuous runtime.
Pro Tip
For cycling appliances, real-world runtime is longer. With a 15% duty cycle, expect 24.9 hours of elapsed time before depletion.
