Delivery and Shipping

Add some general information about your delivery and shipping policies.

This USB-C Multiport Adapter with DisplayPort 1.4 (Alt Mode) and MST, features three video output options (HDMI, VGA and USB-C video) to support a single or multi-monitor workstation. The USB-C video port supports USB 3.2 Gen 2 (10Gbps) with 10W of power, to connect a USB-C monitor or a USB-C peripheral. In addition, the Docking Station also features a 2-Port USB-A 3.2 Gen 2 (10 Gbps) Hub, a Gigabit Ethernet port, and providing advanced charging through a USB Power Delivery (PD) 3.0 pass-through port. The Multiport Adapter connects to a laptop's USB-C or Thunderbolt 3/4 port, using the integrated 10-inch (25.4cm) USB-C cable. The USB Type-C Docking Station features three video output options to turn your laptop into a single or multi-monitor workstation. The HDMI port provides HDR video with resolutions up to 4K 60Hz. The VGA port provides analog video with resolutions up to 1080p 60Hz. The USB-C port provides the industry's first downstream full featured video or data (10Gbps) USB-C port that supports DP Alt Mode video or peripheral connection, on a non-Thunderbolt adapter. This Docking Station utilizes MST to obtain video versatility. Video performance is based upon the number of attached monitors and the host computer's video controller. A laptop with a discrete GPU is recommended for maximum performance. The USB 3.2 hub features two USB-A ports and one USB-C port, for connecting your USB devices. The downstream USB-C port can be used to connect a monitor, or USB-C peripheral with up to 10W of power.

USB-C video does not work

This is advertised as supporting "portable USB-C monitor up to 12W", however my LG gram +view monitor is never detected when plugged into this. The monitor works fine plugged directly into my thinkpad or when plugged in through my surface dock, but not through this adapter. I've tried upgrading the dock firmware and tried multiple different 100W+ chargers and cables but no luck.

USB DP Alt Mode buggy

I bought these specifically for the USB-C DP Alt mode (usb-c display pass through). Supplying power to the hub, plugging into the AR glasses set to 60hz (Xreal Airs) the glasses powered up, but flickered. The flickering is mostly a snall line of dead pixles that randomly appears horizontally, however at several points in the first 5 minutes the display would black out momentarily. I am able to eliminate the power supply (by plugging in another pass through adaptor I have), and the USB-C Cable between the video output (phone) and the glasses, as it is the same I use daily (including as I type this review) with no issue. Which leaves only this Hub as the cause. There aren't a lot of USB-C DP Alt mode hubs at this price point (So I use a powered USB-C to HDMI cable and an HDMI hub currently) but if you are needing the alt mode display then maybe avoid this one. Its possible I got a bad one, but the flickering and cutout makes it unusable for me. The other ports probably work fine, but I wont be testing them any further. Kind of a bummer.

Does not justify the price

USB hubs are great area for scams. They can actually provide us with proper hub which would deliver most of user's needs. but they have to make hundreds of products and advertise them for different functionality. For this hub; if you wanna use Display port and other functionality you do need to connect the hub to power via usb. otherwise it does not work. It does seem like a plug and play compare to thunderbolt and other usb4 hubs but its not.

USB-C video passthrough!

One of the few USB-C docks on the market that can do video pass-through to a USB-C monitor. Works great paired with GooVis Young T2.
