Visualizing: Steam Deck Docks: Power & Video Specs
The Steam Deck requires 45W to charge at full speed while playing. If you use a dock, the math changes.
The Passthrough Penalty
Most USB-C docks consume 10W to 15W just to power their own chips and ports. If you plug a 45W charger into a dock, only 30W-35W reaches the Deck.
Recommendation
To ensure full speed charging while docked, use a 65W GaN charger. This provides enough headroom for the dock's electronics and the Deck's maximum draw.
