Will the Anker SOLIX C300 DC Portable Power Station run a steam deck / handheld?

Yes — the SOLIX C300 DC Portable Power Station runs a steam deck / handheld comfortably

Its 300W continuous output easily covers the 25W draw.

Estimated runtime
about 9 hours
on a single full charge
Est. usable (AC): 220 Wh
Appliance draw: 25 W
Continuous output: 300 W

How we calculated this

We start from the Anker SOLIX C300 DC Portable Power Station's 220 Wh of estimated usable energy at the outlet — its 288 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the steam deck / handheld's 25W draw:

220 Wh ÷ 25 W ≈ 8.8 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.
