Est. usable (AC): 784 Wh

Appliance draw: 25 W

Continuous output: 1800 W

How we calculated this

We start from the EcoFlow Delta 3 Plus's 784 Wh of estimated usable energy at the outlet — its 1,024 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the steam deck / handheld's 25W draw:

784 Wh ÷ 25 W ≈ 31.4 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.
