Est. usable (AC): 392 Wh

Appliance draw: 15 W

Continuous output: 500 W

How we calculated this

We start from the Anker 535 PowerHouse's 392 Wh of estimated usable energy at the outlet — its 512 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the wi-fi router / modem's 15W draw:

392 Wh ÷ 15 W ≈ 26.1 hours

Real-world runtime varies with temperature, cable losses, and how hard the appliance actually cycles. Treat this as a solid estimate, not a guarantee.
