JSAUX docking station 100W

The HDMI output is rated for 4K at 120Hz, giving this JSAUX dock a higher-refresh option for a compatible external display than a dock limited to 4K at 60Hz. It also brings wired Ethernet, two USB-A ports and USB-C power delivery together, which can make a handheld gaming setup easier to use at a desk. One important catch: the product name mentions the ROG Ally X, but the compatibility notes explicitly say it is not compatible with that device. Treat the detailed exclusions as the safer guide before buying.

How to use it

Connect a supported handheld to the dock, then use HDMI for an external monitor or TV, Ethernet for a wired network connection, and the USB-A ports for accessories. For example, you could set a Steam Deck OLED on a desk, connect a controller through USB-A, plug in Ethernet and send the picture to a monitor while charging. That is a more settled, desk-based setup than using the handheld on its own, it is less suited to anyone who wants a compact travel hub with several modern, high-speed USB ports.

The dock supports up to 100W power delivery, but the charger is not included. The listing says to use the original charger for full-speed charging and recommends a 100W charger for the ROG Ally’s 30W Turbo Mode. Case fit is another practical detail: it is not compatible with protective cases that have a kickstand, and the stated case thickness limit is less than 2mm. Does the extra HDMI refresh-rate support matter if your screen does not support it? Only if you have a compatible display and want to make use of that output capability.

Pros

• HDMI output supports 4K at 120Hz, rather than stopping at 4K at 60Hz.
• A five-in-one layout combines HDMI, 100Mbps Ethernet, two USB-A 2.0 ports and USB-C charging.
• The aluminium-alloy construction gives the dock a metal build, rather than a basic plastic housing.
• It is listed for Steam Deck, Steam Deck OLED, ROG Ally, Legion Go and MSI Claw.

The main trade-off is the port selection. Ethernet is specified at 100Mbps, and USB-A is version 2.0, so this is a straightforward connection hub rather than a dock focused on faster wired networking or newer USB speeds. The 4K@120Hz figure is an output capability, not a promise that every game or display will run at that resolution and refresh rate.

Spec sheet

• Type: 5-in-1 docking station
• Model: HB0602S upgraded
• Video: HDMI, up to 4K at 120Hz
• Ethernet: RJ45, 100Mbps
• USB: Two USB-A 2.0 ports, USB-C port with up to 100W power delivery
• Material: Aluminium alloy
• Compatibility notes: The listing excludes ROG Ally X, AYANEO and Nintendo Switch. It also excludes protective cases with kickstands, cases must be less than 2mm thick. Charger not included.

There is a mismatch worth taking seriously: ROG Ally X appears in the product name, while the compatibility note says it is not supported. The detailed exclusion is the more useful buying signal here, so don’t assume the dock will work with an Ally X. It makes sense if you have one of the explicitly listed compatible handhelds and mainly need monitor output, basic USB connections and charging in one desk setup.

What I’d decide

This dock is a reasonable fit for a supported handheld that will spend time connected to a monitor, especially if HDMI 4K@120Hz and a metal body matter more to you than high-speed USB or faster Ethernet. It is not for you if you need confirmed ROG Ally X compatibility, use a kickstand case, or depend on more than 100Mbps Ethernet. The case limit and excluded devices narrow the choice, so match those details to your exact handheld and setup before settling on it.
