Estimated runtime

on a single full charge

Est. usable (AC): 196 Wh

Appliance draw: 10 W

Continuous output: 300 W

How we calculated this

We start from the EcoFlow River 2's 196 Wh of estimated usable energy at the outlet — its 256 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the phone charge's 10W draw:

196 Wh ÷ 10 W ≈ 19.6 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.
