Amazon Prime Day 2025 is delivering big savings across Steam Deck accessories, and I’ve rounded up the best of the bunch. If you fancy upgrading your storage looking for a dock to plug into your setup, or grabbing a power bank that keeps the Deck running on the move, this list covers it. Everything here is discounted, Deck-friendly, and worth a look while the deals are live.

Steam Deck Powerbanks

I’ve been using the SHARGEEK 170 as my daily carry and it’s a beast. It powers up the Deck, the phone, and even the laptop when I need it. With 140W total output and a sharp LCD display, it’s smart, fast, and surprisingly compact for something this powerful.

If you’re looking for value, UGREEN’s 20,000mAh 100W power bank is an absolute gem. It charges three devices at once, fills itself up in under two hours, and has enough juice to run the Steam Deck, a phone, and more. Plus, it’s lighter than you’d expect for something this capable.

The Anker 737 is the one I grab for travel. It’s got enough juice to charge my Steam Deck almost twice, and the 140W fast charging keeps downtime to a minimum. Plus, that smart display is just cool, showing exactly what’s going on with your power.

If I’m just popping out for a few hours, I throw the Anker Prime 9,600mAh in my bag. It’s got a built-in plug, recharges fast, and delivers 65W of clean power. The size is perfect and the screen gives a nice touch of info without overdoing it.

The CUKTECH NO.20 surprised me with its build quality. It’s got this sleek, matte finish with a futuristic blue light strip and a bright TFT display that’s super readable. With 140W output and 25,000mAh capacity, it handles the Steam Deck and then some.

Steam Deck Micro SD Cards

The 1TB Samsung PRO Plus Sonic (It’s actually Shadow) is easily one of the fastest microSDs out there. With 180MB/s read speeds and that fun Sonic branding, it’s ideal for loading games quick on the Deck.

This 512GB version of the Samsung PRO Plus Sonic is a good mid-range pick. Same speedy performance as its 1TB sibling, but for less money if you don’t need loads of storage. Bonus: it comes with an adapter too.

The SanDisk 1TB card is officially licensed for the Switch, but it runs great in the Steam Deck. Loads fast, super reliable, and comes in fun designs like Zelda and Mario if you’re into it.

Lexar’s 1TB Play Blue card is designed with handheld gaming in mind. It’s A2-rated, so games and apps load quickly, and with up to 160MB/s speeds, you’re getting a lot of performance for a pretty fair price.

At 512GB, this Lexar PLAY card hits the sweet spot for size and speed—especially if you’re not quite ready to jump to 1TB. It’s A2-rated too, so loading times stay snappy on the Deck.

PNY’s 2-pack of 256GB cards gives you flexibility—load one up for gaming, the other for media or backups. They’ve got great speed ratings and come with adapters for more devices, which is always a plus.

The SanDisk Ultra 1.5TB card is for anyone who wants to go *big*. It’s not the fastest of the bunch, but if you want to store dozens of AAA games without juggling files, this is the way to do it.

The Samsung 256GB Sonic card is great if you’re just building out your Steam Deck setup. It’s fast, durable, and has the same playful Sonic theme as the bigger models. Plus, it won’t break the bank.

The SanDisk 2TB Extreme is a monster of a card,great for creators and power users who need to store a ton of video or game files. With up to 240MB/s read speeds, it’s as premium as microSD cards get.

Steam Deck Docks

If you just want a no-fuss hub to add a few ports, the HenHot Dock keeps things simple and super affordable. It’s got all the essentials including USB-C power, HDMI, and three USB ports—in a compact footprint.

JSAUX’s 5-in-1 Dock is a reliable all-rounder. It plays nice with the official Steam Deck charger and has enough connectivity for keyboard, mouse, and display without turning your desk into a cable jungle.

UGREEN’s 9-in-1 Dock really cranks up the options. With Ethernet, SD card slots, and more, it’s ideal if you’re treating the Deck like a desktop. Plus, that foldable stand is surprisingly handy.

The Maxonar Loot Dock is one of those do-it-all bases that actually looks good too. Six ports, sturdy construction, and a decent discount make it a smart pickup if you need flexibility.

This upgraded 6-in-1 JSAUX dock plays nice with Steam Deck, ROG Ally, Legion Go, and more. It’s got HDMI 2.1 with 4K at 120Hz, gigabit Ethernet, dual USB-A ports, and PD charging. Plus, the modular stand design lets you dock or detach for flexible setups.

Not gonna lie, I love Anker gear for how polished it feels—and their 6-in-1 Dock is no exception. Clean design, great build, and all the right ports for powering your Steam Deck setup in style.

Mini M.2 drives

The WD_BLACK SN770M is a performance beast, especially for a 2230-sized drive. It’s Gen 4, hits up to 5,150MB/s, and fits right into the Steam Deck with no fuss. If you’re upgrading for speed and storage, this is a solid bet.

This 2TB version of the WD_BLACK SN770M brings huge capacity and incredible speed to the Steam Deck. With read speeds up to 5,150MB/s and trusted TLC 3D NAND, it’s a plug-and-play upgrade that’ll have your load times flying. Definitely one to grab while it’s marked down, just make sure you select the sold by Amazon “Used – Like New” option.

SABRENT’s Rocket 2230 has been a go-to for Steam Deck upgrades. It’s fast, reliable, and Gen 4 compliant. And if you’ve got a heat spreader or thermal pad already, this one drops in clean.

Need a budget-friendly boost? The KingSpec 512GB drive is perfect if you’re just looking for more space without blowing the budget. It’s Gen 3×4, so not the fastest—but way faster than a microSD.

fanxiang’s 1TB Gen 4 NVMe is one of the better budget options I’ve seen lately. It holds its own for game loading, and while the brand’s not huge, it’s earned some decent reviews for value.

The Kingston 1TB Gen 4 is known for stability and performance. If you’re sticking with brands you trust and want plug-and-play confidence, this one delivers.

Steam Deck Controllers

The NACON Revolution 5 Pro is mega if you want a tournament-grade controller (providing you like the PlayStation-style layout. It’s wireless, customizable, and looks sharp in that Field Camo finish. It’s pricey, but this Prime Day cut makes it way more tempting.

The Hyperkin Duke is pure Xbox nostalgia. That big old layout isn’t for everyone, but if you used the original Xbox, you’ll get a kick out of this. Plus, the build quality is great and it’s plug-and-play on PC or Deck.

The 8Bitdo Ultimate Bluetooth controller is a fan favorite for a reason. It’s super comfortable, has Hall effect sticks, and comes with its own charging dock. A great upgrade if you’re ready to ditch drift forever.

The 8Bitdo Ultimate 2 is basically a refined version of their already-great controller. It adds back paddles and improved software support. I’ve tried earlier models and they’ve always been reliable, so this new one looks like a solid evolution.

SCUF’s Valor Pro is built for serious players. If you want programmable back buttons, swappable sticks, and a wired connection that never lags, this one brings pro features without the wireless price bump.

The Xbox Velocity Green controller is a safe bet—solid, familiar, and now slightly cheaper. Works out of the box with the Steam Deck over Bluetooth, and the green shell really pops in person.
