The Steam Deck accessories most worth considering depend on what is getting in your way: limited game storage, carrying protection, power away from an outlet, or connecting a display and peripherals. Start with a compatible microSD card if you need more room for games; consider a second case or a dock only if it fills a specific need. Valve includes a carrying case with the configurations shown on its product page, so extra protection is optional rather than essential.
Which Steam Deck accessories are worth buying?
Choose by use case rather than treating every add-on as a must-have. A microSD card addresses storage, a travel case or sleeve adds a separate carrying option, a USB-C dock or hub connects external displays and peripherals, and a spare charger or power bank may help when traveling. Valve documents these compatibility basics, but the available specifications do not establish that any particular grip, stand, case, charger, or battery improves comfort or performance.

- Need more game storage: look for a compatible microSD card.
- Need a different way to carry the Deck: consider a case or sleeve that fits your model and use.
- Want a desk or TV setup: compare docks and hubs by their ports, display support, and power delivery.
- Spend long periods away from an outlet: check charger or power-bank specifications against your needs; no universally suitable power bank is established here.
Check which Steam Deck model you own
Valve lists different specifications for the LCD and OLED models. These are device specifications, not changes an accessory can make. They are also relevant when shopping for fitted cases or shells.
| Model | Published weight | Battery capacity | Manufacturer gameplay range | Display size |
|---|---|---|---|---|
| Steam Deck LCD | Approximately 669 g | 40 Wh | 2–8 hours | 7 inches |
| Steam Deck OLED | Approximately 640 g | 50 Wh | 3–12 hours | 7.4 inches |
Figures are from Valve’s LCD technical specifications and OLED technical specifications. Valve describes gameplay duration as dependent on content, so the ranges are manufacturer estimates, not guaranteed play times.

Add storage with a compatible microSD card
For a library that exceeds the Deck’s internal storage, a microSD card is the clearest accessory category to consider. Valve says all models support expansion through a high-speed microSD slot, and lists UHS-I along with SD, SDXC, and SDHC support. Its product page says games stored on a microSD card appear in the library instantly.
Search for “Steam Deck microSD card,” then confirm the listing identifies a supported format and a capacity that suits your library. The cited specifications do not establish that a particular brand, capacity, or card will deliver a specific loading-time improvement; no individual card is endorsed here. See Valve’s LCD, OLED, and Steam Deck product pages for compatibility details.

Choose extra carrying protection only for a specific need
Valve lists a carrying case among the included items for the configurations shown on its product page. A second case, a sleeve, or a different carrying setup may still suit a particular routine—for example, if you want a separate bag-friendly sleeve or a distinct way to organize the Deck while traveling. Those are reasons to compare options, not evidence that an extra case is necessary.
Recommended Free Tools
Search for “Steam Deck travel case” or “Steam Deck protective sleeve.” Before buying, check that the product is made for your exact LCD or OLED model. For fitted cases and shells, verify cutouts and access to the controls and ports; do not assume the two models are interchangeable. Valve’s Steam Deck product page lists included items.

Use a dock or USB-C hub for displays and peripherals
A dock is useful when you want to connect the Deck to an external display, wired network, or peripherals. It is an optional setup accessory, not a requirement for handheld play. Valve says third-party hubs and docks can be used as well as its own Docking Station.
Valve’s Docking Station specifications list three USB-A 3.1 Gen 1 ports, Gigabit Ethernet, DisplayPort 1.4, HDMI 2.0, and USB-C power passthrough. Valve lists display support up to 4K at 60 Hz or 1440p at 120 Hz for the Docking Station. These are the dock’s published capabilities; the result in a particular setup also depends on the display, cable, power supply, and other equipment.

- Its supported display modes, size, and weight.
- Whether its stand or layout works with your protective case, if you use one.
Search for “Steam Deck USB-C dock” or “Steam Deck dock with Ethernet,” and check the specific product’s compatibility and power documentation. Valve’s Docking Station technical specifications detail its ports and display modes; its Dock page notes that third-party hubs and docks are an option.

Plan charging around the Deck’s USB-C power requirements
Valve specifies a 45 W USB-C PD 3.0 power supply for both LCD and OLED models. Its listed cable lengths differ: 1.5 m for LCD and 2.5 m for OLED. A spare charger may be convenient for travel, but check that its documented USB-C PD output meets your requirements.
A power bank may also be useful when you expect to be away from an outlet, but the available specifications do not establish a required bank capacity, tested performance, or one option that suits every setup. Check current product documentation rather than assuming a bank will deliver a particular amount of play time. Valve’s model specifications are available for the LCD and OLED.
Quick Recap
Make a short list before you buy
- Identify your model: check whether your Deck is LCD or OLED, especially before choosing a fitted case or shell.
- Name the problem: decide whether you need more storage, a different carrying option, external connectivity, or charging away from home.
- Verify the listing: confirm the accessory’s format, model fit, ports, display support, or power output as applicable.
- Skip what does not solve a real need: a dock is for an external setup, and an extra case is a choice beyond the included carrying case.
