Est. usable (AC): 1,567 Wh

Appliance draw: 25 W

Continuous output: 2400 W

How we calculated this

We start from the EcoFlow Delta 2 Max's 1,567 Wh of estimated usable energy at the outlet — its 2,048 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the steam deck / handheld's 25W draw:

1,567 Wh ÷ 25 W ≈ 62.7 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.
