⚡ Power Math & Safety Analysis
The EcoFlow DELTA 2 Max delivers 2400W of continuous power, which comfortably exceeds the TENS Pain Relief Unit’s 5W operating draw. This gives you a 2395W safety margin.
After accounting for 85% inverter efficiency, the usable capacity is 1741Wh. Dividing this by the appliance’s power draw yields approximately 348.2 hours of continuous runtime.
Pro Tip
For cycling appliances, real-world runtime is longer. With a 60% duty cycle, expect 580.3 hours of elapsed time before depletion.
