Valve Steam Deck Docking Station - Official Dock. I purchased this new along with a Steam Deck, but I haven't had much opportunity to use it, so I'm selling it. It's in excellent condition with no noticeable damage. --- The Steam Deck Docking Station is designed to add expandability to your gaming setup. Connect your Steam Deck to your living room TV, set it up on your desk, or charge it on your side table. The dock is perfect for expanding where and how you use your Steam Deck.
