Which Steam Deck Accessories Are Actually Worth It?
After the Deck itself, a handful of accessories deliver the biggest quality-of-life upgrades. A dock or USB-C hub turns your Deck into a console for the TV. A power bank doubles your unplugged playtime. A good case protects it in your bag, and a set of low-latency earbuds keeps the audio crisp on the go. Everything below plugs into the Deck’s USB-C port or works wirelessly — no fiddly setup required.
What to Look For
- USB-C Power Delivery: docks and hubs should pass through enough wattage to charge the Deck while you play.
- Capacity & PD output (power banks): aim for 20,000mAh+ with 45W USB-C PD for full-speed charging.
- Build & fit (cases): a snug, padded case that fits the Deck plus a charger and SD cards.
- Low latency (audio): wired or aptX/low-latency Bluetooth earbuds avoid lip-sync issues.
- Compatibility: everything here works with the Steam Deck’s standard USB-C and Bluetooth.

The best-reviewed Steam Deck-compatible accessories you can buy right now, spanning docking, power, and audio:
Setting Up Your Steam Deck Accessories
Most accessories are plug-and-play. For docked play, connect a USB-C dock to your TV via HDMI and plug in the Deck — SteamOS automatically switches to the big screen. For longer sessions, keep a high-wattage power bank in your bag; the Deck charges fastest with 45W+ USB-C PD. Pair Bluetooth earbuds in Settings → Bluetooth, and consider a carry case to protect the screen and store your cables and microSD cards together.
Frequently Asked Questions
Do I need a special Steam Deck dock?
No — any quality USB-C hub with HDMI and Power Delivery works. Dedicated docks just add convenience and a stable stand.
What size power bank is best for the Steam Deck?
A 20,000mAh bank with 45W USB-C PD roughly doubles your playtime and charges at full speed.
Will wireless earbuds add audio lag?
Low-latency (aptX/gaming-mode) earbuds keep lag minimal; wired USB-C audio is the most reliable for competitive play.
Are these compatible with the Steam Deck OLED?
Yes — the OLED uses the same USB-C and Bluetooth standards, so these accessories work with both models.
