JSAUX’s 6-in-1 Switch 2 dock folds flat and outputs 4K, but check your cables first

The Bottom Line: A Travel-Friendly Dock That Fixes Nintendo’s Omissions

The JSAUX 6-in-1 Switch 2 dock is the portable, do-everything alternative to Nintendo’s official dock that actually makes sense for modern setups. It folds flat for travel, outputs 4K/60Hz over HDMI, and adds an RJ45 ethernet port that Nintendo still refuses to include. The 100W USB-C PD input keeps the console and a Pro Controller charged simultaneously during long TV sessions. Just know that the “6-in-1” promise depends entirely on bringing your own high-wattage power brick and a modern HDMI cable; otherwise, that 4K signal will flicker or drop the moment the Switch 2 pushes its GPU.

What the Port Stack Actually Solves

Most Switch 2 owners face the same three setup frustrations: the official dock is a space-hogging brick, there’s no wired internet option, and charging multiple devices requires a rat’s nest of adapters. JSAUX attacks all three at once.

The folding design is the immediate win. Collapsed, it’s roughly the footprint of a large phone case, which makes it actually portable. If you move your Switch 2 between rooms, take it to a friend’s apartment, or just hate clutter under your TV, that fold-flat mechanism matters more than any spec sheet suggests.

The HDMI output supports up to 4K at 60Hz. Here’s the reality check: this dock doesn’t upscale games beyond what the Switch 2 renders internally. If a title outputs at 1080p or 1440p, that’s what you’re getting, regardless of the dock’s 4K capability. What the spec actually guarantees is full compatibility with the Switch 2’s maximum TV output mode, including clean HDR passthrough where the game supports it. You won’t hit 120Hz in TV mode through this dock-that’s reserved for handheld play and certain dedicated monitor setups-but for living-room gaming on a TV, 4K/60Hz is the practical ceiling, and this dock hits it cleanly.

Then there’s the RJ45 port. The Switch 2’s Wi-Fi is fine for browsing, but anyone downloading massive first-party titles or playing competitive multiplayer knows the pain of a lag spike. Plugging into this dock gives you a stable wired connection that immediately removes the variable of crowded airwaves. For ranked matches or large digital downloads, that alone is worth the price of admission over the official dock.

Power Delivery and Real-World Charging

The dock accepts up to 100W through its USB-C PD input. The Switch 2 itself won’t draw that full amount, but the headroom isn’t waste-it’s overhead. When you’re running the console in TV mode, charging a Pro Controller through a USB-A port, and pulling data through the ethernet jack, that extra wattage prevents the power-splitting headaches that plague under-powered third-party docks.

JSAUX also designed the unit to function as a charging stand when folded. In tabletop mode, it props the Switch 2 up while feeding it power, which means you don’t need a separate travel charger just to keep playing on the go. It’s a small flexibility, but it turns one accessory into a universal dock rather than a single-purpose TV cradle.

Compatibility Checks You Need to Run

This is where impulse buyers get burned. First, the HDMI cable. To maintain a stable 4K/60Hz signal, you need a cable rated for HDMI 2.0 or higher. That dusty High-Speed cable from 2016 might handshake at 4K but drop to 30Hz or introduce screen flicker under load. Budget for a current-gen cable if you don’t already own one.

Second, power adapter behavior. The dock is engineered around the Switch 2’s PD profile, but it still needs a capable brick to reach that 100W ceiling. If you’re recycling a 30W phone charger, expect inconsistent performance or slow battery drain during intensive gameplay. The safest path is pairing this with a 100W PD adapter that explicitly lists 15V/3A or 20V/3A output profiles. Without that, voltage sag during demanding sessions can trigger the dock to reset or cause the console to throw a low-power warning.

Third, SD Express and cartridge support. Many 6-in-1 docks include card slots, but compatibility varies wildly. If the JSAUX unit has an SD card slot, verify whether it supports SD Express speeds—the standard the Switch 2 uses—or if it falls back to older UHS-I rates. A slot limited to UHS-I turns a 30-minute game transfer into an overnight job. More importantly, check whether the dock’s physical frame blocks the Switch 2’s game cartridge slot. If you still buy physical games and swap carts regularly, a dock that covers the slot turns a minor annoyance into a daily frustration.
