Top 5 Steam Deck accessories to make your setup more portable, including slim cases, fast chargers, and expandable storage.
Taking a Steam Deck out of the house sounds great until you try to pack it. It’s chunky, the original case is huge, and the charger isn’t exactly travel-friendly. After a few days of carrying it around, you’ll probably start thinking about trimming things down. Things like compact docks, slim cases, and better ways to charge on the go. If you’ve been trying to make the Deck more portable without turning it into a mess of cables and pouches, these five picks are worth checking out.
Best 5 Steam Deck Accessories To Enhance Portability
JSAUX ModCase
The JSAUX ModCase is more than just a protective case. It’s a modular case built specifically for Steam Deck users who want flexibility without bulk. The case comes with a detachable front cover, a rear plate that supports additional grips, and a back-mounted strap to hold a battery pack or dock. It adds a bit of thickness, but the modular design helps offset that by offering smart ways to carry more gear in one neat setup.
This can come in useful if you don’t want to carry a separate bag for cables or a charger. The ability to mount accessories directly to the case makes it a good solution for mobile gaming. You still get access to all ports and buttons, and the soft inner lining helps protect the screen from scratches during travel.
Tomtoc Slim Carrying Case
Tomtoc’s Slim Case is tailored for gamers who want protection without the bulk of traditional hard-shell cases. It’s thinner than Valve’s official case but still offers solid protection. The outer shell is made from EVA, a rigid material that absorbs shocks well without feeling too stiff. Inside, a soft fleece lining cushions the device, and a small mesh pocket keeps cables and cards secure.
For commuters or travelers who need to slip the Steam Deck into a backpack, the slim profile is a real win. Unlike bulkier cases, the Tomtoc doesn’t take up half your bag. The zipper is smooth, the materials feel premium, and it holds up well over time. It’s a smart pick if you move around a lot but don’t want your case to double as luggage.
Anker 733 Power Bank
Power is a problem when you’re gaming away from an outlet. The Anker 733 Power Bank solves that with a 10,000mAh battery paired with a 65W USB-C charger. That means it charges the Steam Deck quickly, without needing to plug into a wall, and it can top up your phone at the same time. Unlike generic power banks, this one also functions as a wall adapter. Plug it in, and it turns into a direct charging hub.
It’s ideal for situations like airport layovers, long train rides, or coffee shop gaming. You don’t need to bring a separate charging brick, and you avoid low-battery anxiety. The compact size makes it easy to pack, and it has enough capacity to charge the Deck at least once fully. If you are in the market for Steam Deck accessories, a good power bank must be on your radar.
Dbrand Project Killswitch
The Dbrand Project Killswitch is one of the most purpose-built Steam Deck accessories with serious attention to detail. It includes a textured grip shell, a kickstand, and a travel cover. The newer model also fixes earlier issues with fan clearance and dock compatibility. What makes it stand out is how it manages to be rugged without becoming overbuilt. The grip texture adds confidence when holding the Deck on crowded commutes or uneven terrain.
Dbrand includes a stick-on mount for accessories like a USB-C hub or SSD. The kickstand folds flat when not in use and doesn’t add wobble. You can drop it in a bag without worrying, and if you’re using it as a portable desktop with a dock, it transitions smoothly from handheld to tabletop mode. Everything about it feels like it was designed by people who use the Deck on the go.
SanDisk Extreme microSDXC 1TB
The Steam Deck’s built-in storage fills up fast, especially with larger games. That’s where the SanDisk Extreme 1TB microSD card comes in. It’s fast enough to load AAA games directly and reliable enough to survive daily use. With read speeds up to 160MB/s and A2 application performance, games run smoothly, and installs are quick.
What makes it a travel essential is how it expands your library without needing to carry an external SSD or dock. Just pop it in and go. It’s ideal for players who switch between multiple titles or download updates while away from home Wi-Fi. It also gives you peace of mind with water, shock, and temperature resistance, which matters when your gear gets tossed into a crowded backpack.
Getting the most out of the Steam Deck on the move takes more than just the console itself. Accessories like the JSAUX ModCase or the Tomtoc Slim Case help with carrying and protection. The Anker 733 keeps you powered when wall sockets are out of reach, while Dbrand’s rugged shell lets you grip and protect the Deck with confidence. And with the SanDisk Extreme microSD, you’re not stuck choosing which games to delete before a trip.
