JSAUX 7-in-1 Docking Station (HB0705) for ROG Ally X, ROG Ally, Steam Deck & Legion Go
Product description
The essentials (what this dock is for)
A docking station can either make your handheld feel like a proper living-room setup, or it can turn into yet another box of cables. This JSAUX 7-in-1 dock is aimed at people who want to plug a compatible handheld into a bigger display and peripherals without fuss. It brings HDMI for high refresh 4K/120Hz-style output, wired networking via Gigabit Ethernet, and USB connectivity, plus it includes a cooling fan for the ROG Ally X.
On paper, it’s built for a “one-cable” style routine: dock your handheld, connect HDMI to your TV/monitor, plug in Ethernet if you care about stability, and use USB accessories for controller charging, storage, or basic extras. The design is also modular: you can use the base fully mounted to dock, or separate it as a standalone support.
Key points
The headline attraction is the HDMI 2.1 output up to 4K at 120Hz (and also supports higher-speed modes such as 1080p at 240Hz), alongside features like VRR, ALLM, HDR and QFT. That matters if you’re sensitive to smooth motion and you like pairing a handheld with a modern TV that supports gaming-friendly settings.
It’s also not just “ports in a box”. There’s a magnetic RGB cooling fan included, designed to align with the ROG Ally X air intake for more efficient cooling. You can remove it when you don’t want the fan fitted.
Where it shines in everyday use
If your goal is a consistent home setup, this dock’s mix of connectivity is the practical part: HDMI for your display, Gigabit Ethernet if Wi‑Fi can be patchy, and USB options (including USB-C 3.0 plus a dual USB A 3.0 pair) for common accessories. There’s also USB-C PD charging at up to 100W, which is important if you want to keep playing without treating charging as a separate chore.
A small but useful detail is the included silicone pad for stability and support angles. It won’t magically transform performance, but it can make docking feel less wobbly and more “set it and forget it”.
And yes, the RGB is there: the dock base offers multiple RGB modes, while the fan has its own gradient lighting behaviour. If you’re not into it, you may simply ignore the lighting, if you are, the fan and base are built to look cohesive rather than random.

Compatibility & requirements (important limitations)
This dock is described as compatible with ROG Ally X, ROG Ally, Steam Deck, Legion Go and Legion Go S. However, there’s a very specific note: it is not compatible with ROG Xbox Ally X (2025) and ROG Xbox Ally (2025).
There’s also a real-world cooling caveat worth taking seriously. The cooling fan is described as being designed to align precisely with the ROG Ally (X) air intake. The brand notes that efficiency may reduce when used with other handheld models, simply because air intake placement can vary.
One more requirement: the ROG Ally/Ally X “Turbo 30W” mode needs a 100W PD charger connected (not included). If you don’t have the right charger, Turbo mode won’t work.
Pros
- HDMI 2.1 output is geared towards smooth gaming (up to 4K@120Hz / 1080p@240Hz)
- Gigabit Ethernet for a more stable wired connection
- USB-C PD charging up to 100W, so you can charge while docked
- Included magnetic RGB cooling fan, designed for ROG Ally X alignment
- Modular base lets you dock normally or use the unit as a standalone support
When it might not be for you
It may not be a great match if you mainly want ultra-simple “plug in and forget it” docking, because you’ll need to think about charger wattage if you care about Turbo 30W. It also might not be the best choice if you’re relying on the cooling fan to perform as well across different handhelds—cooling efficiency is explicitly tied to air intake alignment, and the dock itself warns it can be lower on non‑ROG Ally models.
And if your display doesn’t support the relevant gaming features (like VRR/ALLM in practice), some of the HDMI headline specs may matter less than you’d hope.
Should you buy it?
Buy it if you want a 7-in-1 docking station built around HDMI 2.1 gaming output, wired Gigabit Ethernet, and onboard charging, and you own one of the listed compatible handhelds. The included magnetic fan is a strong extra if your device is a ROG Ally X, because the alignment is described as intentional rather than generic.
Skip it if you have one of the specifically excluded 2025 ROG Xbox Ally models, or if you don’t plan to use Ethernet/USB accessories and you’d rather not manage the “Turbo 30W needs a 100W PD charger” requirement.
Mini FAQ
Does the fan come included?
Yes. The dock includes a magnetic RGB cooling fan that’s designed to be removable.
Will Turbo 30W work without a charger?
No. Turbo 30W requires a 100W PD charger connected (not included), and won’t function without it.
Is it compatible with Steam Deck and Legion Go?
It’s listed as compatible with Steam Deck, Legion Go and Legion Go S, although the cooling efficiency may reduce on non‑ROG Ally models due to air intake positioning differences.
What’s the main video connection?
The dock uses HDMI 2.1, with support for up to 4K@120Hz (and also higher-speed 1080p modes) along with features such as VRR, ALLM, HDR and QFT.
