The best ROG Ally X accessories depend on whether you play in your hands, carry the console, or use it with a television. Start with a USB-C dock for TV gaming, then add protection and charging gear for travel; storage, a controller, and audio are optional.
One important correction: the 2024 ROG Ally X (model RC72LA) is not an OLED handheld. ASUS specifies a 7-inch, 1,920 × 1,080 IPS-level screen running at 120 Hz. The accessory advice below is for that RC72LA model, so remove “OLED” from searches and listings that refer to a different device.

Why is a dock the first accessory for TV gaming?
A dock is the most useful TV accessory because it combines video output, charging, and peripheral connections in one cable. ASUS specifies two USB-C ports on the RC72LA. Both carry DisplayPort and power delivery; the USB4 port is listed as Thunderbolt 4 compliant and supports DisplayPort 1.4 with FreeSync and Power Delivery 3.0. That makes a USB-C dock with HDMI output the logical bridge to a television or monitor.

Choose a dock by matching its published capabilities to your display rather than by the number of sockets alone. Check these items:
- HDMI output: Confirm the dock’s stated resolution and refresh support against the TV or monitor. Do not assume every USB-C hub offers the same HDMI mode.
- Power delivery pass-through: Look for USB-C PD input and enough output for the Ally X’s charging requirements. A dock’s maximum pass-through figure is not automatically the same as the power delivered after the dock uses some power itself.
- USB ports: Count the ports you actually need for a controller, keyboard, mouse, external drive, or Ethernet adapter, and check whether they are USB-A, USB-C, or a mixture.
- Stand and cable layout: A stable cradle and a short, correctly oriented cable reduce strain on the handheld’s port. Make sure a protective case will not prevent the Ally X from seating.
- Power supply: Some docks include a suitable adapter and some do not. Treat the charger as a separate purchase unless the listing clearly specifies what is included.
- Compatibility wording: Verify support for the ROG Ally X/RC72LA, not merely generic “USB-C video.”
ASUS lists a ROG Gaming Charger Dock as an official accessory category. Its listing confirms that this type of product exists for the ecosystem, not that every revision or regional bundle has identical ports or that it is the best choice for every television. Read the dock’s current specification sheet before buying.
How do I connect the ROG Ally X to a TV or monitor?
Use a dock or USB-C hub with HDMI, connect the dock to adequate USB-C power, then select the correct HDMI input on the display. The exact Windows display options depend on the TV, monitor, dock firmware, and cable.
- Check the display and dock ratings. Confirm the dock’s HDMI mode, the display’s input capability, and whether the dock supports the refresh rate you want.
- Connect power to the dock. Use a USB-C PD adapter that meets the dock’s stated input requirement. If the dock is unpowered, USB peripherals and charging may be limited.
- Connect HDMI from the dock to the TV or monitor. Select that display’s HDMI input.
- Attach the Ally X. Use the USB-C connection specified by the dock maker. The USB4 port offers the broadest documented feature set, but the second USB-C port also supports DisplayPort and power delivery.
- Set Windows display mode. Press Windows + P and choose Duplicate, Extend, or Second screen only. For couch play, “Second screen only” avoids leaving the handheld panel active.
- Set resolution and refresh rate. Open Settings > System > Display > Advanced display. Select a mode supported by both the dock and the TV/monitor.
- Pair your input devices. Connect a controller by its documented USB, Bluetooth, or wireless receiver method. If you use a receiver, plug it into a dock port with a suitable data connection.
If the picture is blank, reseat the USB-C and HDMI cables, select the correct input, and test with a lower display mode. If the image works but the Ally X is not charging, check the dock’s PD input, the charger’s output, and whether the dock reserves part of the input power for itself. The ASUS manual identifies the USB4/DisplayPort/Power Delivery and USB 3.2 Gen 2 Type-C/DisplayPort/Power Delivery connections; follow the port labels and the regional manual for your unit.
What case fits the ROG Ally X?
A case is worthwhile if the Ally X travels in a bag, but fit is more important than branding. ASUS lists an ROG Ally Premium Hard Case, yet product names can cover more than one Ally generation. Confirm that the current listing explicitly supports the 2024 RC72LA before ordering.

Compare a case on five practical dimensions:
- Device fit: The shell should identify the Ally X/RC72LA, not only the original ROG Ally. Check for cutouts around both USB-C ports, the microSD slot, triggers, and ventilation.
- Coverage: A hard exterior and a shaped interior protect against pressure in a backpack; a soft sleeve is lighter but offers less structural protection.
- Grip bulk: A thick shell can make the 678 g handheld harder to hold for long sessions and may interfere with third-party grips.
- Storage: A compartment for a charger, HDMI cable, or microSD cards is useful, but loose accessories should not press against the screen.
- Dock clearance: If you plan to play docked without removing the case, verify that the case’s bottom opening and thickness match the dock. Many protective shells require removal.
Do not infer impact performance, hinge durability, or dock compatibility from a product photo. Those characteristics require the maker’s own fit information or independent evidence; the available ASUS material only establishes the official case category.

One free scan finds every outdated or missing driver and matches the right update for your exact hardware.Free scan · exact hardware matchDo I need a second charger for the Ally X?
Buy a spare charger only after checking whether your box already contains one and which regional bundle you received. ASUS lists a 65 W USB-C adapter specification and says charger inclusion varies by country, region, and model.
For a replacement or travel unit, look for:
- USB-C Power Delivery: The charger should state its PD profiles and output clearly, rather than simply advertising a high total wattage.
- At least the required output: Use the Ally X’s 65 W specification as the reference point, while checking the charger label and ASUS guidance for your region.
- Correct plug: Select the plug style and electrical rating used where you will charge.
- Cable included or not: Some adapters require a separate USB-C cable rated for the intended power. A cable that only supports low-power charging can become the limiting component.
- Port allocation: Multi-port chargers may reduce the output available to the Ally X when another device is connected.
ASUS also lists a 140 W USB-C GaN charger. A higher maximum rating does not prove faster gameplay charging in every setup: the handheld, cable, charger profile, and workload all determine the negotiated power. Treat 140 W as headroom for compatible devices, not as a guaranteed Ally X performance upgrade.
Is a microSD card necessary?
No. The RC72LA already includes a 1 TB PCIe 4.0 NVMe M.2 2280 drive, so a microSD card is an optional expansion rather than a required accessory. It is useful for a large game library, installers, screenshots, or media that you do not want on the internal drive.
ASUS specifies a UHS-II reader supporting SD, SDXC, and SDHC. That tells you which card families the reader accepts; it does not, by itself, establish an ideal capacity, sustained speed, or game-loading result. Compare a card’s published capacity, bus rating, warranty, and return policy, and avoid choosing solely from a headline “up to” speed.

To install one, shut down or suspend downloads, insert the card in the Ally X’s microSD slot with the contacts oriented as shown in the manual, and let Windows detect it. In Settings > System > Storage, review the new drive before moving a game library. Format only after confirming that the card contains no data you need.
Should I buy a controller for TV play?
A controller becomes valuable when the Ally X is on a stand or across the room from the television. It is not necessary for handheld play, because the device has integrated controls. ASUS lists the ROG Raikiri Pro PC Controller among related products, but you still need to verify its connection method and compatibility for your exact setup.
For docked use, decide whether you want a wired USB connection through the dock, Bluetooth, or a wireless receiver. Wired input avoids pairing and battery management but consumes a dock port and may require a long cable. Bluetooth reduces cable clutter but adds a pairing step and depends on the controller’s own battery and Windows support. A receiver can provide a dedicated wireless link, provided the dock exposes a compatible data port.
When comparing controllers, prioritize button layout, analog-stick placement, trigger feel, remapping software support, and whether the device can wake or control Windows reliably. Those are preference and compatibility questions, not specifications established by the Ally X page.

Pick the symptom - the matching free tool is one click away.
Which audio accessory works best?
Choose between the built-in 3.5 mm jack and Bluetooth based on latency, cable tolerance, and whether you need a microphone. The Ally X includes a 3.5 mm audio jack and Bluetooth, so you can use wired headphones, wireless earbuds, or a headset without a dock.

ASUS lists the ROG Delta S Wireless Gaming Headset and ROG Cetra True Wireless Gaming Earbuds as related products. Confirm each model’s supported connection modes, Windows compatibility, microphone behavior, and charging case or headset battery requirements before purchase. A headset using a USB receiver may need a free dock port in TV mode; Bluetooth earbuds avoid that cable but can require separate pairing and may expose codec or microphone limitations.
For private TV play, check whether the television, dock, or Ally X is handling audio output. In Windows, open Settings > System > Sound and select the intended output device. If sound remains on the handheld, change the output after the HDMI display appears or select the TV/dock audio endpoint manually.
What does the Ally X’s hardware mean for accessory choices?
The core specifications explain why these accessories are useful. ASUS lists Windows 11 Home, a 7-inch 1,920 × 1,080 120 Hz IPS-level display, 1 TB PCIe 4.0 NVMe storage, an 80 Wh battery, and a 678 g weight for RC72LA. The device has one USB 3.2 Gen 2 Type-C port with DisplayPort and power delivery, plus one USB4 Type-C port with Thunderbolt 4 compliance, DisplayPort 1.4 with FreeSync support, and Power Delivery 3.0. ASUS notes that specifications can change.
The two USB-C ports are the key constraint. A dock can consolidate HDMI, charging, and accessories, but it also becomes a single point of failure. A case can protect the handheld, but its thickness can block dock insertion. A controller and headset improve couch ergonomics, but they add pairing, charging, or port-management decisions. Think of the setup as a chain: handheld port, cable, dock, charger, display, and input device must all support the mode you want.

For mostly handheld play
- Verify the Ally X model and keep the included charger if it is present.
- Add an RC72LA-specific hard case if the console travels.
- Add a microSD card only when the internal 1 TB drive no longer meets your library needs.
- Choose wired or Bluetooth audio according to your tolerance for cables and latency.
For a permanent TV or monitor setup
- Choose a USB-C dock with HDMI, documented display support, PD pass-through, and enough USB data ports.
- Use a charger that meets both the dock’s input requirement and the Ally X’s charging specification.
- Keep a controller paired or connected through the dock.
- Use wired or wireless audio depending on whether other people are sharing the room.
For travel between handheld and TV play
- Use a case whose cable compartment can hold the dock’s short HDMI and USB-C leads without pressing on the screen.
- Carry one known-compatible PD charger and label it if several USB-C chargers are in the same bag.
- Test the display mode at home before traveling, including controller pairing and audio output.
- Leave enough space for ventilation; do not cover the handheld or dock openings with fabric.
What should I do when a docked setup fails?
- No image: Confirm the TV input, reseat HDMI, reconnect dock power, and try the Ally X’s other USB-C port. Then use Windows + P and select a display mode.
- Image flickers or falls back to a low mode: Check the dock’s HDMI specification, cable quality, and the TV’s selected input mode. Choose a conservative resolution and refresh rate first.
- Ally X battery still drops: Verify that the charger is connected to the dock’s PD input, that the dock supports the needed pass-through, and that a second device is not consuming the available output.
- USB controller is not detected: Move it to a data-capable port, reconnect the dock, and check Windows’ Bluetooth & devices or USB device list. A charging-only port will not carry controller data.
- Audio stays on the handheld: Open Settings > System > Sound and select the HDMI/TV output, then check the television’s volume and mute state.
- Case prevents docking: Remove the case or use a dock with a longer, correctly positioned USB-C lead. Never force the connector against a misaligned opening.
How we picked these accessory recommendations
The ranking follows the Ally X’s documented ports and the two distinct reader jobs: handheld portability and external-screen play. A dock ranks first because it directly enables HDMI TV/monitor use and can combine power and peripherals. The case and charger follow because they affect safe transport and reliable power. Storage, controller, and audio are preference-led additions.
Selection criteria were: documented compatibility with the RC72LA, support for the relevant USB-C, DisplayPort, Power Delivery, microSD, Bluetooth, or 3.5 mm interfaces; fit and cable-clearance considerations; regional charger availability; and the ability to explain limitations without claiming independent performance. No accessory was labeled a tested winner because the available sources do not provide comparative accessory testing.
Bottom line: which accessories should you buy first?
For TV gaming, buy a compatible USB-C dock with HDMI and PD pass-through, then match it with a suitable charger and a controller if you do not want to use the handheld’s controls. For handheld travel, prioritize an RC72LA-specific hard case and keep the supplied 65 W charger or buy a clearly specified replacement. Add a UHS-II microSD card, headset, or earbuds only when your storage, audio, or privacy needs justify them. Always verify the 2024 Ally X model: its built-in panel is a 120 Hz IPS-level display, not OLED.
Frequently Asked Questions
Can the ROG Ally X output 4K to a TV?
The USB4 port is specified with DisplayPort 1.4, but the final resolution and refresh rate depend on the dock, HDMI conversion, cable, television, and Windows display mode. Check the dock’s published HDMI limits instead of assuming that every USB-C hub supports the same 4K mode.
Will a case for the original ROG Ally fit the Ally X?
Do not assume it will. The 2024 Ally X has a different model designation, so look for explicit RC72LA or Ally X compatibility and confirm port, trigger, and dock clearance before ordering.
Can I charge the Ally X through either USB-C port?
ASUS lists both USB-C ports with power delivery. The USB4 port additionally carries Thunderbolt 4 compliance and DisplayPort 1.4; use the port and cable arrangement specified by your dock or charger and follow the regional manual.
Is UHS-II required for every microSD card used in the Ally X?
The reader supports UHS-II as well as SD, SDXC, and SDHC, but that does not make a UHS-II card mandatory. Choose capacity and performance based on your storage workload and the card’s published specifications.
Why might the charger be missing from my Ally X box?
ASUS says adapter inclusion varies by country, region, and model. Check the package contents and the rating label for your unit before buying a second 65 W USB-C PD charger.
