Handheld gaming PCs have one small problem that becomes obvious the moment you want to use them like a desktop console. The Steam Deck, ROG Xbox Ally X, Legion Go 2, and MSI Claw series use USB-C connectivity for charging and external displays. A separate dock or hub becomes useful when you want to connect a TV, wired Ethernet, keyboard, mouse, or other USB devices while also charging the handheld.

That makes a handheld gaming dock more than a simple accessory. The market ranges from first-party models to budget hubs, with Valve listing its Steam Deck Docking Station at $79.00, JSAUX at $39.99, Anker’s A83S1 at $35.99, and UGREEN’s 75126 at $34.99 sale price / $45.99 regular price. But price alone tells you very little. Display standards, charging power, USB ports, Ethernet, compatibility, physical design, and what is included in the box can make one dock a much better fit for your setup than another.

This guide is for Steam Deck, ROG Ally, ROG Ally X, ROG Xbox Ally, ROG Xbox Ally X, Legion Go, Legion Go 2, and MSI Claw owners who want a reliable dock for a TV, monitor, desk setup, or wired network. We compare budget, performance, compatibility, connectivity, durability, and long-term value so you can choose a dock based on how you actually plan to use it.

With more than 20 years of experience in hardware and application research and development, we assess each product on the factors that matter after you buy it: real-world usability, hardware quality, durability, performance, and value for money. Our recommendations are based on extensive research, component analysis, real-world usability, and industry expertise. The goal is not to pick the most expensive dock, but to identify the right dock for each type of user.

We do not conduct our own laboratory bench tests for this comparison. Instead, we cross-check manufacturer specifications, current retailer listings, and independent coverage, giving greater weight to what manufacturers publish themselves. We also checked the current product pages again before publication because model numbers, compatibility lists, prices, and power specifications can change. Where a manufacturer does not publish a figure, we say so rather than estimate it.

Four Widely Repeated Claims That Need Correction

Claim 1: “The Valve Steam Deck Docking Station costs $89.”

Valve’s official Steam store currently lists the Steam Deck Docking Station at $79.00 USD. The $89 figure was the launch price in October 2022 and still appears in older comparison articles. The current

$79 price narrows the gap with third-party docks and should be used for today’s value comparison.

Claim 2: “The Valve dock offers dual-monitor output over DisplayPort.”

Valve’s documentation supports two external displays through MST, using both the HDMI and DisplayPort outputs. It does not provide two-monitor output through DisplayPort alone. Valve also notes that Steam Deck’s Gaming Mode currently does not mirror or use multiple displays at the same time; multiple-display use requires Desktop Mode.

Claim 3: “The JSAUX HB0603 is limited to HDMI 2.0 and 4K@60Hz.”

The model number is the source of the confusion. JSAUX’s current upgraded models are HB0603S and HB0612, and both are specified with HDMI 2.1 at up to 4K@120Hz. JSAUX also lists the older HB0603 standard version as HDMI 2.0 at 4K@60Hz. HB0612 adds compatibility with the ROG Xbox Ally and ROG Xbox Ally X; the other listed functions are the same as HB0603S. Buyers should check the exact SKU rather than rely on a generic product title.

Claim 4: “The Anker A83S1 supports the ROG Ally X.”

Anker explicitly excludes the ROG Ally X from the A83S1’s compatibility list and product title. Its current product information lists support for Steam Deck, Steam Deck OLED, ROG Ally, and Legion Go. Several comparison pages still list the A83S1 more broadly, which is why the manufacturer’s current compatibility note should take priority.

Compatibility, model numbers, and power figures are the areas where this category is easiest to misread. They can change the buying decision, so we treat manufacturer documentation as the primary reference.

Verified Specification Comparison

Figures below were checked against current manufacturer information and current retailer listings in September 2026. Where a manufacturer does not publish a figure, the cell says so rather than estimating it.

Three points are worth drawing out.

Valve is the only one of these four with DisplayPort 1.4 and MST. That is a real functional difference if you need two external displays, although Valve’s current setup requires both HDMI and DisplayPort outputs to be occupied.

Two of the four support 4K@120Hz over HDMI: JSAUX HB0603S/HB0612 and UGREEN 75126. Valve’s dock is limited to 4K@60Hz over HDMI 2.0, while its DisplayPort 1.4 output is listed up to 1440p@120Hz.

Anker and UGREEN both publish device-output figures: Anker lists up to 90W, while UGREEN lists up to 85W from its 100W PD input. JSAUX does not publish a device-output wattage, and Valve does not state one as a separate wattage figure.

PD-In vs PD Passthrough: The Steam Deck Dock Wattage Figure Most Listings Omit

Nearly every dock here advertises “100W PD.” That number refers to PD input — the maximum power the dock accepts from a wall charger. It is not automatically the amount delivered to the handheld.

The dock itself uses some of the incoming power for its controller, USB hub, Ethernet and display hardware. The remaining power is available to the handheld. That is why the input rating and device-output rating should be treated as separate figures.

What this means for a buyer: a 100W-capable dock does not guarantee 100W at the handheld. Anker publishes up to 90W output, UGREEN up to 85W, while JSAUX does not publish a separate output figure. Steam Deck power needs are lower than those of some Windows handhelds, but the result still depends on the charger, dock, cable, connected peripherals, and the handheld’s workload.

There is a related detail that matters on higher-power Windows handhelds: higher performance modes can depend on the charger and dock. JSAUX recommends a 100W charger for the ROG Ally’s 30W Turbo Mode, while UGREEN states that a 100W PD charger is required for 30W Turbo Mode on the ROG Ally, ROG Ally X and MSI Claw. Requirements vary by handheld generation and model, so check the dock maker’s current guidance for the exact device rather than assuming one rule applies to every handheld.

One further point from Valve’s own FAQ: the Steam Deck Docking Station will operate without its power supply attached, but USB throughput is reduced because the Deck alone has limited output power. That is a useful behaviour to know if the PSU is ever left behind.

Practical conclusion: the dock is one link in a power chain. A 100W-capable dock paired with a 45W charger cannot deliver more than the charger supplies. If you are buying for a high-power Windows handheld, check both the dock’s published device-output figure and the charger requirement for your exact handheld.

Device Compatibility: The ROG Xbox Ally X Dock Problem

This is where the category becomes genuinely confusing.

The ROG Xbox Ally and ROG Xbox Ally X make compatibility more important because manufacturers have updated some existing docks with new support while leaving older variants unchanged. A dock that works with the original ROG Ally or ROG Ally X is not automatically listed as compatible with the newer Xbox-branded models.

“Not certified by Valve” is too strong as a compatibility label. Valve’s current support guidance says most USB-C-compliant hubs and docks work with Steam Deck, while Thunderbolt and DisplayLink docks may work but are not officially supported. For this table, “Not officially listed by Valve for this device” is more accurate than treating the dock as incompatible.

“Not listed” means the manufacturer does not currently confirm or exclude the device. We have not treated silence as either support or incompatibility.

Decoding the JSAUX HB0603, HB0603S and HB0612

This is the easiest JSAUX product line here to get wrong because the model numbers look similar but do not have the same compatibility list.

JSAUX currently sells the upgraded HB0603S and HB0612 as closely related 6-in-1 docks:

• HB0603S — 6-in-1, HDMI 2.1 at 4K@120Hz, 100W PD input, three USB-A 3.0 ports and Gigabit Ethernet. JSAUX lists it for Steam Deck, ROG Ally/Ally X and Legion Go/Go 2/Go S, but excludes the ROG Xbox Ally/X and Nintendo Switch/Switch 2.
• HB0612 — JSAUX’s ROG Xbox Ally/X JSAUX states that HB0612 adds ROG Xbox Ally/X compatibility while the other functions are the same as the HB0603S.

The practical difference is compatibility, not the main port or display specification.

If you own a ROG Xbox Ally or ROG Xbox Ally X, choose the HB0612 rather than the HB0603S. If you own a Steam Deck, ROG Ally or Legion Go, the HB0603S is the relevant upgraded model.

A caution on listings: older Amazon and retailer pages may use HB0603, HB0603S or a generic “6-in-1” title. If a listing contradicts JSAUX’s current compatibility notice, use the exact model number and the current manufacturer page as the deciding reference.

Case Compatibility: Worth Checking Before Ordering

Cradle docks hold the handheld in a fixed slot, which has to accommodate any case.

JSAUX publishes physical dimensions for its current models: HB0603S is 140 × 77.5 × 36 mm and HB0612 is 140 × 85 × 58 mm. Because these are cradle-style docks, thick cases can affect fit. JSAUX also provides separate case/modcase guidance for some models, so check the exact case allowance before ordering.

By contrast:

• UGREEN’s 75126 uses a foldable, adjustable aluminium stand rather than a fixed slot, so it is generally more accommodating of different handheld sizes and cases.
• Anker’s A83S1 is a flat hub with a rubberised base, so it does not have the same cradle-fit issue as the fixed-slot docks. However, Anker states that cases with a kickstand are not supported and that case thickness should not exceed 2 mm. It also does not hold the handheld upright.
• Valve’s Docking Station is a moulded Steam Deck cradle with a rubber seat and captive 90° connector. If you use a case, check the physical fit rather than assuming the cradle will accommodate

If a case stays on permanently, an adjustable stand or a flat hub avoids the fit question entirely.

Individual Assessments

Valve Steam Deck Docking Station — listed at $79.00 USD

Valve’s dock remains the strongest first-party option for Steam Deck users who need DisplayPort or dual external displays. HDMI 2.0 limits HDMI output to 4K@60Hz, but DisplayPort 1.4 adds a different display path. Valve also provides firmware updates and includes a power supply, which reduces the need to buy a separate charger.

What it provides that the other three do not: DisplayPort 1.4, MST multi-monitor support, FreeSync/VRR support, firmware updates, an included power supply, and first-party Steam Deck support. The current multi-monitor setup requires both HDMI and DisplayPort outputs to be in use.

The DisplayPort output can matter more than the headline HDMI number suggests. A 1440p@120Hz display is a useful target for some Steam Deck use cases, although actual gaming performance depends on the game and settings.

Suited to: Steam Deck owners who want DisplayPort, multi-monitor output, or first-party support, and who value the included PSU.

Less suited to: owners of Windows handhelds, and anyone whose use case is a single TV.

Limitations: it is the highest-priced dock in this comparison, its main advantage is concentrated around Steam Deck features, and its cradle can be less convenient for users who keep a thick case on the handheld.

JSAUX HB0603S (and HB0612) — listed at $39.99 USD sale price / $49.99 regular price

The current HB0603S and HB0612 match Valve’s three USB-A ports and Gigabit Ethernet, while adding HDMI 2.1 at up to 4K@120Hz and 100W PD input. JSAUX currently lists the upgraded models at

$39.99 on sale, versus a $49.99 regular price.

The trade-offs are clear. There is no DisplayPort, so these models do not provide MST multi-monitor output. JSAUX does not publish a separate device-output wattage, and the model-number split matters if you own a ROG Xbox Ally or ROG Xbox Ally X.

Independent testing of the earlier JSAUX HB1101 reported 4K@60Hz output and Gigabit Ethernet throughput in the 940–952 Mbps range. That is historical data from a different SKU, not a measurement of the current HB0603S or HB0612, so it should not be treated as a current specification.

Suited to: buyers wanting a Valve-comparable port layout with a higher HDMI specification at a lower price, who confirm the model number first.

Less suited to: buyers who need DisplayPort or dual-monitor output, and ROG Xbox Ally/X owners who select the HB0603S instead of the HB0612.

UGREEN 75126 — listed at $34.99 USD sale price / $45.99 regular price on UGREEN US at the time of publication

The 75126 has one of the broadest current manufacturer-published compatibility lists and explicitly includes the ROG Xbox Ally and ROG Xbox Ally X on UGREEN’s US product page.

Specification: HDMI 2.1 at 4K@120Hz with VRR, FreeSync and G-Sync support, 100W PD input with up to 85W delivered to the host, Gigabit Ethernet, two USB-A ports at 5Gbps, and one USB-C data port at 5Gbps. It also has a foldable adjustable aluminium stand and a detachable USB-C cable.

The detachable cable is a practical advantage: if the cable fails, you can replace the cable rather than the dock, and you can choose a different length or connector angle.

Two caveats. It has one fewer USB-A port than JSAUX or Valve, which matters if you connect several wired peripherals. Also, UGREEN’s regional pages have not always shown identical Nintendo compatibility information, so check the current page for your region and exact SKU if Switch support matters to you.

Suited to: households running several different handhelds, particularly anyone with a ROG Xbox Ally X or a cased device.

Less suited to: anyone needing three or more USB-A ports, or DisplayPort.

Anker A83S1 — listed at $35.99 USD (Best Buy)

The A83S1 has the narrowest feature set here and the clearest power documentation. It provides HDMI at 4K@60Hz, Gigabit Ethernet, two USB-A ports and one USB-C data port at 5Gbps, and 100W PD input with up to 90W delivered to the device. Anker does not publish the HDMI version.

Two characteristics distinguish it. It is one of the few docks here with a published device-output wattage, which makes power planning easier. It is also a compact hub-style design rather than a cradle. Anker states that cases with a kickstand are not supported and that case thickness should not exceed 2 mm.

Anker’s current compatibility information lists Steam Deck, Steam Deck OLED, ROG Ally and Legion Go, while explicitly excluding ROG Ally X, AYANEO and Nintendo Switch devices. Legion Go 2 and MSI Claw are not listed as supported.

Suited to: Steam Deck owners wanting TV output, wired Ethernet and a simple budget option, who already have a stand.

Less suited to: ROG Ally X, ROG Xbox Ally/X, Legion Go 2 or MSI Claw owners, and anyone wanting output above 60Hz.

Direct Comparisons

Valve vs JSAUX. JSAUX offers HDMI 2.1 at 4K@120Hz, three USB-A ports and a lower price. Valve answers with DisplayPort 1.4, MST, an included PSU and first-party Steam Deck support. For two external displays, Valve is the only one of the four with MST. For a single TV, JSAUX offers the stronger headline display specification for less money.

UGREEN vs JSAUX. Both offer HDMI 2.1 at 4K@120Hz at similar prices. JSAUX has three USB-A ports; UGREEN has two USB-A ports plus USB-C data, an adjustable stand, a detachable cable, up to 85W host output and direct support for the ROG Xbox Ally/X. For mixed-handheld households, UGREEN is the safer pick if those newer ASUS models are part of the setup.

Anker vs UGREEN. The current UGREEN US sale price is slightly lower than the Anker price used in this review. Remember that the Valve dock includes a power supply, while the third-party docks compared here generally require a separate USB-C PD charger. For that difference, UGREEN adds 4K@120Hz, VRR/FreeSync/G-Sync support, an adjustable stand, a detachable cable and up to 85W host output. Anker’s counter is its published 90W output figure and compact hub-style design.

Any of these vs a USB4 or Thunderbolt desktop dock. A more expensive desktop dock makes sense when it also serves a laptop and you need higher bandwidth or broader multi-display support. For handheld-only use, the extra cost is harder to justify.

Which Dock Suits Which Buyer

Setting Up a Handheld Dock

Connection order can affect whether the display handshake completes cleanly, although problems can also come from the cable, display input, dock firmware or the handheld.

1. Confirm the exact model number, not just the HB0603S and HB0612 look similar but differ in support for the ROG Xbox Ally/X.
2. Connect the dock’s USB-C cable to the handheld before powering anything on.
3. Plug the PD charger into the dock’s dedicated power Use a charger that meets the requirement for your exact handheld; for many high-power ASUS handheld setups, a 100W PD charger is the recommended choice.
4. Connect the display cable to a display that is already switched Some televisions do not complete the handshake if powered on afterwards.
5. Verify output in SteamOS under Settings → Display, or in Windows Display Settings.
6. Test Ethernet by disabling Wi-Fi temporarily and confirming the wired connection is active.
7. Watch the battery indicator during the first ten minutes of a demanding If the battery declines while docked, check the charger rating, dock output specification, cable, connected peripherals and the handheld’s performance mode before assuming the dock itself is faulty.
8. Retain the packaging through the seller’s return window so you can test the dock with your actual handheld, case, display and charger.

Frequently Asked Questions

How much does the official Valve dock cost?

Valve currently lists the Steam Deck Docking Station at $79.00 USD on the Steam store. The $89 USD figure quoted in older articles was the October 2022 launch price.

Is the official Valve dock necessary for a Steam Deck?

No. Valve’s current support guidance says most USB-C-compliant hubs and docks work with Steam Deck. The Valve dock’s distinguishing features are DisplayPort 1.4, MST, FreeSync/VRR, firmware updates, an included PSU and first-party support.

Does the JSAUX HB0603S work with the ROG Xbox Ally X?

No. JSAUX lists the HB0603S as not compatible with the ROG Xbox Ally or ROG Xbox Ally X. The HB0612 is the current JSAUX model that adds support for those two devices.

Is the JSAUX dock HDMI 2.0 or HDMI 2.1?

The older HB0603 is an HDMI 2.0 model rated for 4K@60Hz. The current upgraded HB0603S and HB0612 are HDMI 2.1 models rated for up to 4K@120Hz. The model number determines the answer.

Does the Anker A83S1 support the ROG Ally X?

No. Anker’s current product information explicitly says the A83S1 is not for ROG Ally X. It lists Steam Deck, Steam Deck OLED, ROG Ally and Legion Go.

What is the practical difference between HDMI 2.0 and HDMI 2.1 here?

HDMI 2.0 tops out at 4K@60Hz; HDMI 2.1 allows 4K@120Hz and VRR passthrough. The benefit depends on the display supporting it and the handheld producing those frame rates, which is uncommon at 4K in demanding titles.

What is PD passthrough, and how much is needed?

PD passthrough is the power the dock delivers to the handheld, as distinct from what it accepts from the wall. Anker publishes up to 90W and UGREEN publishes up to 85W. JSAUX does not publish a separate host-output wattage, while Valve does not state one as a standalone wattage figure.

Will these docks work with a Nintendo Switch or Switch 2?

JSAUX currently excludes Nintendo Switch and Switch 2 for the HB0603S/HB0612. UGREEN’s regional listings differ, so check the current product page for your market before buying specifically for a Nintendo console. The Valve dock is documented for Steam Deck, and Anker excludes Nintendo Switch devices.

Can any of these drive two monitors?

Among these four, only the Valve dock offers MST. Valve notes that the current multi-monitor setup requires both HDMI and DisplayPort outputs to be in use, and Steam Deck multiple-display use is currently a Desktop Mode workflow.

Do any require driver installation?

None of these four requires DisplayLink software for its listed display output. Valve notes that DisplayLink docks may work with Steam Deck but are not officially supported.

Does the Valve dock work without its power supply?

Yes. Valve states it functions without the PSU, though USB throughput is reduced because the Steam Deck alone has limited output power.

Summary

The choice comes down to four clear use cases.

For mixed handheld households, the UGREEN 75126 is the strongest all-round choice on published compatibility. It combines HDMI 2.1 at 4K@120Hz, up to 85W host output, a detachable cable, an adjustable stand and published support for the ROG Xbox Ally/X, at $34.99 sale price / $45.99 regular price on UGREEN US at the time of publication; promotional discounts may apply.

For Steam Deck owners who need two external displays, the Valve Steam Deck Docking Station remains the only one of these four with DisplayPort 1.4 and MST. The current $79.00 price is lower than its $89 launch price, although its HDMI output remains limited to 4K@60Hz.

For a single TV, wired Ethernet and charging on a budget, the Anker A83S1 is a simple option, provided its 4K@60Hz limit and compatibility list match your needs.

JSAUX is the value display pick: the current HB0603S/HB0612 models offer HDMI 2.1 at 4K@120Hz, three USB-A ports and 100W PD input. Choose the HB0612 if you own a ROG Xbox Ally or ROG Xbox Ally X.

Two checks can prevent many avoidable buying mistakes: verify the exact model and compatibility list on the manufacturer’s current page, and check the charger and host-output requirements for your handheld before ordering.
