Buying Guides

The ROG Ally and its beefier sibling the Ally X are compelling handheld PCs, but out of the box they’re still just computers in a shell. Whether you want to expand storage, dock your device for the living room or simply protect the screen, the right ROG Ally accessories can dramatically improve your experience. This buying guide rounds up the must‑have add‑ons for both models, so you can squeeze every bit of performance, versatility and comfort from your handheld.

Must‑have essentials

Every owner should start with the basics. These upgrades are cheap, simple and make a big difference.

• Tempered glass screen protector – A three‑pack of amFilm tempered glass costs around $10 and will keep your Ally’s 7‑inch panel free from scratches and greasy fingerprints. Installation is easy and you’ll hardly notice it’s there.
• Thumbstick grips – Skull & Co. makes affordable rubber grips that slip over the analogue sticks. They add surface area and height, improving control when playing shooters or racing games. At roughly $10 a set it’s a no‑brainer.
• High‑capacity microSD card – The Ally and Ally X support UHS‑II microSDs, but those cards command a premium. A reliable UHS‑I card like Samsung’s 1 TB Evo Select offers plenty of extra space for under $70 and is faster than the stock eMMC storage on the base Ally.

Expand your storage

Games are only getting larger, and the 512 GB drive in the base Ally fills up fast. Upgrading to an NVMe SSD requires opening the handheld, but the performance gains are worth it.

• Corsair MP600 Mini M.2 SSD (2230) – The Ally and Ally X both use compact 2230‑size drives. Corsair’s MP600 Mini offers up to 2 TB of speedy storage for around $140. Compared to microSD cards, NVMe drives provide dramatically faster load times and better overall responsiveness. Just be prepared for a delicate installation.
• WD Black SN850X M.2 SSD (2280) – The Ally X uniquely supports 2280‑size drives, giving you access to higher capacities. Western Digital’s SN850X runs cool, hits PCIe 4.0 speeds and is available in 2 TB and even 8 TB variants. If you need vast game libraries on the go, this is the way to go.

Dock and connect

Part of the appeal of a handheld PC is plugging it into a bigger screen or a TV. A good dock adds ports for peripherals and charges the unit at the same time.

• JSAUX HB0702 docking station – Originally designed for the Steam Deck, this $60 dock is equally at home with the Ally. It offers an HDMI 2.0 port, ethernet, three USB‑A ports and a USB‑C passthrough that delivers up to 100 W. Drop your Ally onto the cradle and you’ve got a mini desktop with room for a keyboard and mouse.
• Anker 332 USB‑C hub – If you prefer something more compact, Anker’s 332 hub packs two USB‑A ports, HDMI and SD card slots into a travel‑friendly bar. It supports 85 W passthrough charging and costs around $25.

Improve control and comfort

Handhelds are great on the go, but when you dock the Ally you’ll want a proper gamepad. Even in portable mode, a few tweaks can make long sessions easier on your hands.

• 8BitDo Ultimate Bluetooth Controller – This well‑reviewed pad costs about $70 and includes both Bluetooth and low‑latency 2.4 GHz wireless. It charges in its own dock, uses Hall Effect joysticks to prevent drift and comes with remappable buttons via the 8BitDo app.
• Skull & Co. thumbstick grips – Mentioned earlier, these grips deserve a second nod. They come in different heights and textures, so you can tailor the feel of your Ally’s sticks and reduce fatigue.

Stay powered up

Even with the Ally X’s larger battery, power can be a concern during long sessions or travel days. An external battery keeps you gaming without hunting for outlets.

• Baseus 30,000 mAh 65 W power bank – This high‑capacity battery can charge the Ally or Ally X at full speed, yet costs under $60. It has multiple USB ports and a digital display so you know exactly how much juice is left.
• Anker 737 24,000 mAh 140 W power bank – For those willing to spend more, Anker’s 737 outputs up to 140 W—enough to charge your handheld while simultaneously powering a laptop or phone. A detailed screen shows per‑port output and remaining capacity.

Protect your investment

Dropping your handheld is a gamer’s worst nightmare. A sturdy case protects against bumps and adds useful features.

• Dbrand Killswitch case – This modular case offers rugged protection, a built‑in kickstand and improved grip while maintaining airflow. At $60, it includes a stylish skin and is compatible with the Ally or Ally X.

For the hardcore: external GPU

If money is no object and you want to turn your Ally into a genuine desktop replacement, Asus sells the ROG XG Mobile external GPU dock. It plugs into the Ally’s proprietary port and includes an Nvidia GeForce RTX 4090, turning your handheld into a 4K powerhouse. At around $1,999 it’s wildly overkill and doesn’t work with the Ally X due to port differences, but it shows how far the accessory ecosystem has come.

Final thoughts

With a thoughtfully chosen set of ROG Ally accessories, Asus’s handheld becomes far more than a portable PC. Screen protectors and thumb grips keep the hardware safe and comfortable, expanded storage lets you carry more of your library, docks turn the device into a living‑room console, and external batteries keep you playing on the go. Whether you opt for a budget‑friendly hub and microSD card or go all‑in on NVMe drives and high‑watt power banks, the growing ecosystem around the Ally and Ally X ensures there’s something for every kind of gamer.
