Valve's new handheld gaming PC is still a developing technology, but its accessory market is already crowded enough that we decided to collect the best Steam Deck accessories for Prime Day. Not many big companies are making accessories for Deck yet, so much of what you can find on Amazon right now varies in quality. We not only sorted through Prime Day accessory prices to find the best ones, but also tested many of these products ourselves.

Below we have compiled a list of what we recommend. There are docks, screen protectors, cases, and even backup chargers. You'll also find at least one product that is an absolute must-have for Deck owners, including a microSD card that can instantly expand Deck's memory at a significantly reduced price.
