Best Steam Deck Accessories

The Steam Deck is a more complete product out of the box than most gaming handhelds — it ships with a carrying case, has a decent screen, and runs a full Linux OS with access to most of your Steam library. But a few accessory categories genuinely improve the day-to-day experience in ways the stock hardware doesn't cover: storage expansion, protection for travel, and docking for TV play. Here's what's actually worth buying, in priority order.

Priority Order: What to Buy First

If you're buying accessories for the first time, here's the order that makes the most practical impact:

1. Screen protector — the stock screen scratches easily; this is day-one protection
2. MicroSD card — unless you have the 512GB or 1TB OLED model, you'll need more storage fast
3. Carrying case — the included case is adequate but doesn't store a dock and cables
4. Dock — only if you want to play on a TV or monitor

The Deck's biggest friction points are storage space and protection during travel. Start there before anything else.

Screen Protector — JSAUX Tempered Glass

The Steam Deck's display isn't sapphire glass. The OLED model's display is slightly more durable than the original LCD, but both will pick up surface scratches from dust particles during routine handling. A tempered glass screen protector adds hardness (typically 9H rated) without meaningfully affecting touch responsiveness or display quality.

The JSAUX tempered glass protector is the most consistently recommended option — it fits the bezel without gaps, doesn't interfere with the thumbsticks during installation, and ships with an alignment frame that makes bubble-free application much easier than it sounds. It's around $10–$12 for a 2-pack, which means you have a replacement ready if the first one ever chips.

What to avoid: cheap TPU (soft plastic) protectors. They dull the display slightly and are harder to apply without bubbles. Tempered glass is worth the small premium.

MicroSD Card — SanDisk Extreme 1TB

Storage is the practical limitation of any Steam Deck model with less than 512GB of internal storage. Games routinely hit 50–100GB, and having your library on a fast microSD card makes the Deck feel dramatically more capable.

The SanDisk Extreme 1TB is the reliable choice. It's rated at 190 MB/s read and 130 MB/s write, which keeps game load times competitive with internal storage for most titles. The critical spec to understand is the Application Performance Class: the SanDisk Extreme is A2-rated, meaning it handles the random read/write operations that games require (not just sequential speed) at sustained throughput.

Why A2 matters: A cheaper microSD card might advertise 150 MB/s read speeds but only be A1 rated, meaning random read performance — which is what actually affects game loading — is much lower. Always check the A1/A2 rating, not just the headline speed.

What capacity to buy: 512GB covers a solid library. 1TB is worth the price jump if you have a large game collection and don't want to manage what's installed. 256GB fills up surprisingly fast if you play modern AAA games.

Current pricing: SanDisk Extreme 512GB runs ~$49; 1TB runs ~$79–$99.

Carrying Case — JSAUX Modular Case

Valve's included case protects the Deck fine for simple storage but has no room for a dock, extra cables, or the power brick. The JSAUX Modular Case solves this with a design that lets you attach or remove external zippered pouches to carry whatever you need for a given trip.

The main case holds the Steam Deck with or without a protective shell attached. The modular pouches attach via a zipper system on the outside and can carry a dock, charging cable, USB hub, or SSD separately. For travel where you want the Deck as a desktop replacement (dock for a hotel TV, keyboard for typing, external drive for extra games), this is genuinely useful organization. It's ~$35 for the base case, with optional pouches adding ~$10–$15 more.

Alternative: If you just want the simplest carrying solution and don't travel with a dock, the tomtoc Carrying Case for Steam Deck (~$25) is thinner, lighter, and has a clean interior that fits the Deck snugly with a small accessory pocket for cables. Less versatile but simpler.

Dock — iVoler 6-in-1 Docking Station

Playing the Steam Deck on a TV or monitor requires a dock that handles video output and keeps the Deck charged while in use (the USB-C port can do both, but a dock makes it practical). The iVoler 6-in-1 is the most popular third-party option: it outputs HDMI 2.0 (4K/60Hz capable), has two USB-A 3.0 ports for controllers or keyboards, Ethernet for a wired network connection, and USB-C power delivery.

Why Ethernet matters: the Steam Deck's Wi-Fi is reliable, but a wired connection noticeably improves streaming performance and reduces download times for large game installs when the Deck is docked.

Specs: HDMI 2.0 (supports 4K/60Hz or 1080p/120Hz), 2× USB-A 3.0, 1× USB-C (power delivery), 1× Gigabit Ethernet, pass-through charging up to 100W. Price: ~$35–$40.

Valve's Official Dock: Valve sells an official dock for ~$89 that has the same basic specs but a more stable base design and Valve's support. It's notably more expensive for functionally similar output. Third-party docks work well.

Important: Some early third-party docks caused firmware issues on older Deck units. The iVoler has a strong track record of compatibility. Avoid extremely cheap no-name docks under $15 that lack proper USB-C power delivery spec compliance.

Charger — Anker 45W USB-C Charger

The Steam Deck ships with a 45W USB-C charger. It's adequate but large, and if you want a second charger for travel or desk use, the Anker 737 Nano III (45W) is a much more compact option that delivers the same wattage. Anker's USB-C PD chargers are among the most reliable third-party options — they handle voltage negotiation correctly and don't cause the charging warnings that some cheaper adapters trigger.

Why wattage matters: The Deck charges at up to 45W. A 30W charger will charge it slowly while gaming; a 65W charger will work fine (USB-C PD negotiates the right voltage). Don't use a charger below 30W if you want to charge while playing intensively.

Price: The Anker Nano III 45W runs ~$22–$28, significantly smaller and lighter than the included charger.

Grip — Satisfye ZenGrip Pro

The Steam Deck is wide and the grips are shallow for people with larger hands. The Satisfye ZenGrip Pro adds extended rear grips that make the Deck feel more like a traditional game controller — less cramping during long sessions, better ergonomics for palm-grip users who find the back of the Deck too flat.

It's a rubberized grip attachment that clips onto the Deck without adhesive (so it won't damage the unit). It adds some bulk but makes the Deck significantly more comfortable for 2+ hour play sessions. Price is ~$35.

Who needs it: Players with medium-to-large hands who find the default grips cause hand fatigue during sessions over an hour. Players with small hands generally find the stock ergonomics fine.

Storage Expansion: microSD vs. External SSD

For most users, a fast microSD card covers storage needs. But if you have a very large game library and frequently swap between large titles, an external SSD connected via the dock's USB-A port is noticeably faster for large game installs and nearly as fast for load times.

A 1TB Samsung T7 SSD (~$79) connected via USB 3.0 gives you faster random read performance than any microSD card. The trade-off: you need to be docked to use it, and it's another device to carry. MicroSD works always, including undocked.

Recommendation: Start with a 512GB or 1TB microSD card. If you find yourself regularly hitting its limits, add an external SSD for docked use.

Frequently Asked Questions

Do I need a screen protector if I have the OLED model? Yes. The OLED's display is slightly harder than the LCD model's, but it still scratches with sustained exposure to dust and debris in bags. Tempered glass protectors are inexpensive and eliminate the risk.

Will any USB-C hub work as a dock for the Steam Deck? Many USB-C hubs with HDMI output will work for basic TV connectivity, but not all handle USB-C PD (power delivery) correctly for charging while gaming. Look for hubs explicitly listed as Steam Deck compatible or that specify 45W+ USB-C power pass-through.

Does the Deck's microSD slot support UHS-II cards? No — the Deck uses a UHS-I interface, which caps at around 100–105 MB/s real-world throughput regardless of whether you insert a faster UHS-II card. The SanDisk Extreme (UHS-I) is the right speed tier; UHS-II cards won't perform any better and cost more.

Is it safe to buy a used Steam Deck? Yes, provided you test it thoroughly before purchase. Check both thumbstick drift (run a stick calibration test), screen uniformity (no dead pixels or burn-in on OLED), and fan noise. The original LCD model is still capable; the OLED is worth the price premium for the display quality if you can find it at a reasonable used price.

Bottom line: Screen protector and microSD card first — both are inexpensive and solve immediate practical problems. Add a carrying case when you start traveling with it, and a dock when you want TV play. The grip and additional charger are quality-of-life improvements for long sessions and travel convenience respectively, but lower priority than the first two.
