Valve make a reservation now for its official Steam Deck Docking Station. The dock costs $89. When I made my reservation just minutes after the reservations opened, I got an expected order window between October and December.
Valve’s official dock aims to make it easier to connect the portable gaming PC to a monitor or television. It has three USB-A 3.1 Gen 1 ports, a gigabit ethernet port, a DisplayPort 1.4 port, and an HDMI 2.0 port. The dock connects to your Steam Deck via a USB-C cable that plugs into the USB-C port on the top of the device. It will also come with its own power supply.
