⚡ Power Math & Safety Analysis
The MARBERO Portable Power Station 88Wh delivers 80W of continuous power, which comfortably exceeds the Alexa Smart Speaker’s 15W operating draw. This gives you a 65W safety margin.
After accounting for 85% inverter efficiency, the usable capacity is 75Wh. 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 100% duty cycle, expect 5 hours of elapsed time before depletion.
