⚡ Power Math & Safety Analysis
The EcoFlow DELTA 2 Max delivers 2400W of continuous power, which comfortably exceeds the Portable Shower Heater’s 350W operating draw. This gives you a 2050W safety margin.
After accounting for 85% inverter efficiency, the usable capacity is 1741Wh. Dividing this by the appliance’s power draw yields approximately 5 hours of continuous runtime.
Pro Tip
For cycling appliances, real-world runtime is longer. With a 15% duty cycle, expect 33.2 hours of elapsed time before depletion.
