SpecPicks Verdict

SpecPicks scored JSAUX 12-in-1 RGB Docking Station using a rating × review-volume × price-fit model applied to published specs and reviews across the external storage category. JSAUX's external storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for external storage of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Does the JSAUX HB1201B dock work with the Steam Deck OLED, ROG Ally, and Legion Go?

Yes. JSAUX lists Steam Deck (including OLED), ROG Ally, Legion Go, and MSI Claw as compatible devices. Tablets and laptops that support USB-C video and charging also work.

Can I play at 4K 120Hz on my TV through this dock?

Yes. Both the HDMI port and the DisplayPort support 4K@120Hz when one display is connected. The HDMI port also supports VRR, ALLM, and HDR, but your handheld and TV must support those features too.

Can I connect two monitors at once?

Yes. Windows supports mirror and extend modes, and macOS supports mirror mode only. With two screens connected, output is limited to 4K@60Hz or 2K@120Hz.

How much power does the dock pass through to my device?

The USB-C PD 3.0 port delivers up to 100W. Connect your own USB-C charger to that port. Check the product listing to see whether a power adapter is included.

How do I control or turn off the RGB lighting?

A touch switch on top of the dock turns the lighting on and off. It has six built-in modes. For custom effects or syncing with other RGB gear, connect the upstream USB-C port and use OpenRGB software.
