Steam Deck Accessories UK Worth Buying First
The Steam Deck is built for proper PC gaming in your hands, whether you are clearing a few quests on the sofa, travelling by train or setting up a full-screen session at your desk. But the right Steam Deck accessories UK players choose can make a bigger difference than another game in the backlog. Storage stops install juggling, a solid case protects your kit, and a dock turns a handheld into a flexible home gaming machine.
You do not need to buy every add-on at once. The best setup depends on how and where you play. Start with the accessory that solves your biggest annoyance, then build from there.
Steam Deck Accessories UK Players Should Prioritise
Expand storage before your library fills up
A microSD card is the first upgrade for most Steam Deck owners. Modern PC games are large, and a 256GB or 512GB internal drive can disappear quickly once you add a few big open-world games, racing titles and multiplayer favourites. With expandable storage, you can keep more of your library ready to play rather than uninstalling something every time a new release lands.
Look for a reputable UHS-I microSD card with A2 performance. The Steam Deck does not benefit from expensive UHS-II speeds, so paying extra for a card built around that standard is usually unnecessary. Capacity is the decision that matters most. A 512GB card is a strong all-round choice, while 1TB makes sense for players who want a deep rotation of larger games installed at once.
It is worth buying genuine branded storage rather than chasing a suspiciously cheap listing. A failing card can mean corrupted installs, lost save data and a lot of downloading again. Once fitted, format the card through the Steam Deck itself and it will be ready for game storage.
Choose a case that matches your routine
Your Deck may already have a carry case, but an upgrade can still be worthwhile if you travel often or carry extras. A tougher hard-shell case gives better protection in a backpack, while cases with room for a charger, cable, earbuds and microSD cards stop small essentials being left behind.
The trade-off is bulk. A slim protective case is easier to carry and may fit neatly in a small bag, but it will not offer the same storage or impact protection as a larger travel case. If your Steam Deck mostly moves between rooms at home, a fitted protective shell may be all you need. If it comes on commutes, holidays or weekends away, choose a case with a secure zip, reinforced corners and a dedicated compartment for accessories.
Be careful with thick cases that claim dock compatibility. Some shells prevent the Deck from sitting correctly in a dock or block access to vents and ports. Check that the design is made for your Steam Deck model and does not interfere with cooling.
Protect the screen from the first day
A screen protector is inexpensive insurance for a device designed to leave the house. Tempered glass protectors are popular because they add resistance against scratches and feel close to the original display. They are particularly useful for the standard glossy-screen Steam Deck, which can pick up marks from bags, dust and everyday handling.
Anti-glare protectors are a more personal choice. They can reduce reflections when playing near a window or outdoors, but may slightly change the sharpness and finish of the screen. Steam Deck OLED models already have excellent display quality, so many owners prefer clear tempered glass to preserve that vivid look. If glare ruins your play sessions, however, a matte protector may be the better call.
Take your time fitting it. Clean the screen carefully, line up the cut-outs before removing the backing, and use the supplied guide frame if one is included. A protector is only helpful if it is applied without trapping half the room underneath it.
Charging Gear That Keeps You Playing
The Steam Deck charges through USB-C, which is convenient, but not every USB-C plug is equal. For reliable charging while playing, use a quality USB-C Power Delivery charger that can provide sufficient power. A low-output phone charger may charge the Deck slowly or struggle to keep up when you are running a demanding game.
A spare mains charger is ideal for a second room, work bag or travel case. UK players should choose one with a proper UK plug or a dependable adapter, rather than relying on a loose travel solution. A longer USB-C cable also makes sofa gaming far less restrictive, especially if the nearest plug socket is behind the TV unit.
For portable power, a USB-C PD power bank can extend play away from mains power. Check its output rating as well as its capacity. A huge battery that cannot deliver enough wattage will be less useful than a smaller model with the correct Power Delivery support. Power banks add weight, so they are best for travel and long journeys rather than every quick session.
Turn Your Steam Deck Into a Big-Screen Setup
A dock or USB-C hub is the accessory that gives the Steam Deck its second life. Connect one to a TV or monitor, add a controller, and your handheld becomes a compact PC gaming setup for the living room, bedroom or desk. It is a great option for couch co-op, racing games, retro favourites and any title that feels better on a larger display.
Look for HDMI output, multiple USB ports and USB-C Power Delivery pass-through. Ethernet is useful too if you prefer a stable wired connection for downloads or online play. A dedicated dock gives the cleanest fit and keeps the Deck upright, while a hub is often more compact and can be easier to pack for a mate's house or holiday.
Do not expect every game to run at maximum settings on a 4K television simply because the screen is bigger. The Steam Deck is at its best when settings are chosen sensibly. Lowering the resolution, using performance-focused graphics options or targeting 1080p can produce a much smoother experience. Big-screen gaming is about flexibility, not forcing desktop-level settings from a handheld.
A docked setup also benefits from the right controller. Bluetooth pads are simple and tidy, while wired controllers remove battery concerns and pairing time. Choose a controller layout that suits the games you play most. A familiar Xbox-style pad is excellent for many PC games, while a PlayStation controller can be a comfortable alternative for players used to that stick layout and face-button feel.
Small Upgrades With a Big Everyday Payoff
The Steam Deck already has excellent controls, but a few practical accessories can improve longer sessions. Thumb grips can add texture and protection to analogue sticks, though they need to fit securely without catching against the shell. A stand is handy for tabletop play, watching media or using a separate controller, particularly if you do not want a full dock on your desk.
For audio, wired USB-C or 3.5mm headphones are the straightforward choice for travel. A gaming headset with a microphone is better if you regularly chat with friends online. Bluetooth audio is convenient, but wired options avoid another battery to charge and can be simpler when you just want to start playing.
If you plan to use the Deck like a mini PC, consider a compact keyboard and mouse. Strategy games, management sims, web browsing and desktop mode are much easier with proper desktop controls. This is not a must-have for every owner, but it is a smart addition for anyone who wants their handheld to cover more than gaming.
Buy for Compatibility, Not Just the Deal
A great price is only great if the accessory works properly with your setup. Before ordering, check whether a case supports the original Steam Deck, Steam Deck OLED or both. Confirm that a dock has the ports you need, that a charger supports USB-C Power Delivery, and that a controller is suitable for your preferred connection method.
It also pays to think about the bundle rather than individual products. A travel player may get the most value from a case, screen protector, power bank and spare cable. A home player may be better served by a dock, controller and storage card. At Konsole Kingz, that platform-specific approach makes it easier to shop around the way you actually play, with free UK delivery and reward points adding value to every upgrade.
Start with the accessory that removes friction from your next session. More installed games, safer travel, longer battery life or a proper TV setup: the right choice means less fiddling with your Steam Deck and more time playing it.
