about 24 hours
on a single full charge

How we calculated this
We start from the EcoFlow River 2 Pro's 587 Wh of estimated usable energy at the outlet — its 768 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the steam deck / handheld's 25W draw:
587 Wh ÷ 25 W ≈ 23.5 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.
