The Steam Deck OLED is the most accessory friendly handheld there is. It has full USB-C video output, a large battery, and a huge ecosystem of docks, grips, and add ons built around it. That means the question is not whether an accessory works, but which ones are worth your money. This guide sorts the kit that actually improves the experience from the stuff you can skip. For the full review, read our Steam Deck OLED review.

Best MicroSD Card for the Steam Deck OLED

The Deck installs large modern games, so a fast high capacity microSD card is near essential. A 512GB Samsung PRO Plus is the benchmark pick, with strong sustained read speeds that hold up under the Deck's load. Go bigger if you install a lot of AAA titles. See our best microSD cards guide.

Best Case for the Steam Deck OLED

The Steam Deck OLED is unusual in that it ships with a good carrying case in the box, so the real question is not whether you need a case but whether you need a better one. The answer depends on how much you carry alongside the Deck. If you travel with a charger, a power bank, AR glasses, a dock, and cables, a larger hard shell travel case with internal dividers keeps it all together, and JSAUX and other brands make Deck specific versions. If you find the stock case bulky and carry only the Deck, a slimmer aftermarket case shaved closer to the device goes the other way. Whatever you pick, the 7 inch OLED needs a rigid front.

Best Dock for the Steam Deck OLED

The Deck ships with a carrying case but not a dock. A third party dock from JSAUX adds HDMI output, USB ports, and charging in one cradle for less than the official Valve dock, and it works well. Plug in once and the Deck becomes a console on your TV. See our cooling and docks guide.

Best AR Glasses for the Steam Deck OLED

The Steam Deck is the best handheld to pair with AR glasses. Its full USB-C DisplayPort output and large battery handle the connection cleanly, turning the Deck into a giant private screen on a plane or couch. Viture and Xreal are the brands to compare. See our full AR glasses guide.

Best Portable Monitor for the Steam Deck OLED

If you would rather share the screen, a USB-C portable monitor turns the Deck into a desktop setup anywhere. The Deck can drive a sharp 1440p picture over USB-C, so it is worth a higher resolution panel than most handhelds can use. See our portable monitors guide.

Best Power Bank for the Steam Deck OLED

The Deck is power hungry. To charge while you play, you need a bank that delivers at least 45W of USB-C PD, and 65W or more is better. A high output Anker bank in the 20,000mAh to 25,000mAh range keeps the Deck running on the road and doubles as a laptop charger. See our best power banks guide.

✓ Pros

• Keeps the Deck charged during demanding play
• High capacity for long trips
• Doubles as a laptop charger

✗ Cons

• Heavier than a budget handheld bank
• Costs more for the higher wattage

Best Screen Protector for the Steam Deck OLED

The Deck's glossy 7 inch touchscreen gives you a genuine choice most handhelds do not. Clear tempered glass keeps the OLED looking exactly as it does now, with its punchy contrast and sharpness intact, and is the default for indoor or dark room play. Anti glare etched glass tames the reflections a glossy OLED throws back near windows, outdoors, or under bright lights, trading a touch of sharpness for a much more usable screen in glare. Either way, get 9H glass cut for the 7 inch Steam Deck OLED that preserves touch. It is cheap insurance for a pricey device.

Best Grip for the Steam Deck OLED

The Steam Deck OLED is the one device here that does not need a grip to be comfortable. Valve designed it with full sized grips that suit most hands out of the box, so a grip cover is about texture for sweaty palms and a more secure hold during intense sessions, not fixing a flaw. A textured silicone cover from JSAUX or a similar brand wraps the existing grips in a grippier surface without changing the ergonomics Valve already got right, and some grip cases add rear buttons as a bonus. If you dock often, confirm the cover stays on when the Deck is connected.
