Jsaux Steam Deck docking station review – a great portable gaming PC hub

The Jsaux Steam Deck Dock isn’t the only handheld-compatible USB-C hub from Valve, but its design and features cater specifically to the portable powerhouse. You could go so far as to say that the third-party accessory is a clone of the real deal, because its resemblance is uncanny. Despite this, the price and features of the Jsaux docking station make it a winning alternative, even if its specifications are slightly different.

Much like Valve’s absent accessory, the Jsaux Steam Deck dock transforms the tiny gaming PC into a desktop rig. It doubles as a cradle, so you won’t need to create a makeshift seat for the device while it’s hooked up to your gaming monitor, mouse, and keyboard. If you own a Nintendo Switch, you’ll already be familiar with this type of portable hybrid setup, and this accessory facilitates the same level of versatility.

Again, there are plenty of USB-C hubs that can help you connect the Steam Deck to a TV or monitor. However, alternatives such as Anker, Belkin, and Lenovo are designed for gaming laptops, which means they technically lack physical “docking station” capabilities. By mimicking the official Valve accessory, Jsaux has created a better Steam Deck dock competitor that is ahead of the curve.

Jsaux Steam Deck Dock Design

In terms of build quality, the Jsaux Steam Deck feels solid and feels well made. Its aluminum construction helps add weight, while a rubber cushion protects your deck from scratches (looking at you, Nintendo). However, you will still need to be careful as the metal edges of the accessory could damage your screen if they come into contact.

Jsaux Steam Deck Features

If you’ve ever used a dock at work or at home, you’ll already know what the Jsaux Steam Deck Dock is trying to accomplish. In simple words, it is a hub that allows portable devices to turn into a desktop computer. This particular accessory outfit includes an HDMI 2.0 port, two USB A outlets, Ethernet connectivity, and a USB-C power port.

The set connects to the Steam Deck via an integrated USB-C cable, which runs neatly through the back of the handheld’s back. Sitting the deck on any cradle will never match the slippery nature of the Nintendo Switch, but placing Valve’s portable on Jsaux’s accessory eliminates much of the usual USB hub problem.

For starters, the Jsaux Steam Deck Dock USB-C Cable is custom-made, so you won’t have to worry about extra bits of cord on your desk. The prop also uses the Deck’s chonkiness to its advantage, as its size keeps anything behind it out of sight. In fact, the only evidence of the docking station you’ll see from your gaming chair is a subtle support lip on the front.

That said, I have an issue with Jsaux regarding their decision to sideload the docking station’s Ethernet port. While the Steam Deck’s width hides the connected wires, for the most part there’s something irritating about having a rogue cable separated from the rest of the rear connections. If you place the docking station on the left side of your desk, this is less of a problem, as you can still manage the cables under your desk. Still, I’d rather have a USB port on the side than an Ethernet port, as it could be used to connect a PC controller.

Going back to the USB ports, the Jsaux Steam Deck docking station only has two. It goes without saying that the accessory would benefit from a few extras, especially since most setups include a gaming mouse, keyboard, gaming headset, and other optional items. Of course, you can connect a basic USB splitter, but that will mean spending more money if you don’t have one.

The Jsaux could do with a few extra ports, but you won’t have to worry about juicing everything. The accessory’s USB-C input supports 100W of power – more than enough to keep your Steam Deck charged and your gaming keyboard lights on. The dock doesn’t come with a power supply, but you can use the Deck’s 45W charger or grab another one with more punch.

Jsaux Steam Deck Performance

Before we dive into the capabilities of the Jsaux Steam Deck docking station, it’s worth remembering that it won’t improve the performance of Valve’s handheld. In other words, you can, in theory, hook the laptop up to the best gaming monitor, but it won’t magically start running games at 4K 60fps. If anything, you’ll need to lower your setting a bit to play at 1080p, as the micro machine is designed to run games on its built-in 1280×800 display.

That’s not to say the Steam Deck can’t act as a desktop gaming PC, as the Jsaux docking station helps the device deliver a low-spec desktop experience. Personally, I’ve had a blast playing Xbox 360-era games like Alice: Madness Returns on the big screen, and even the brand new indie cat caper Stray is perfectly playable.

It should be noted that SteamOS is a bit quirky when it comes to mouse and keyboard controls. While switching to desktop mode solves issues for some games, the experience doesn’t feel quite right. Valve is probably working to fix this issue, as it has already fixed resolution scaling issues for beta users.

The Jsaux Steam Deck Docking Station provides a robust desktop gaming experience that extends handheld functionality. It’s also only $39.99, which means you can buy a complete solution for less than an Anker USB-C hub and accompanying stand. Ultimately, the dock’s biggest selling point is its existence, as it effectively plugs a hole left by Valve’s vapourware.
