Satechi has updated its already well-conceived USB 3 mini-dock to version 3, dubbing the new release the USB-C Multiport Adapter 8K With Ethernet V3. This update has nearly the same array of ports, but almost all of them have some additional oomph: greater speed, power, or display resolution.

The dock’s basics are four USB-C data ports, gigabit ethernet, 85W of passthrough energy on a dedicated USB-C power port, HDMI, and an SD Card slot. Sounds good, but dig into the details, and it’s even better.


Three of its four USB-C data ports work at up to 10Gbps (USB 3.2 Gen2); the fourth is 5Gbps (USB 3.1). That’s handy when you need to make fast connections to SSDs or computer-to-computer connections and need ports beyond what’s built into your Mac. This is a step up from three USB-C data ports on the V2 unit, all of which were 5Gbps.

Using HDMI, you can connect an 8K display at up to 30Hz; several Mac models allow this resolution and refresh rate (or faster). You can also connect a 4K display at up to 120Hz. (Your Mac has to support these resolutions and refresh rates as the dock isn’t a video card, just a passthrough.) The V2 version of the dock maxed out at 4K/60Hz, so this is a significant update for those using more advanced displays.

To make room for an extra USB-C port, something had to give, and Satechi shed the dedicated Micro SD slot while retaining a UHS-II full-sized SD Card port. You’ll need an adapter to use Micro SD on the mini-dock, but if you’re like me, you have a few card-sized adapters scattered around from your Micro SD purchases.

The gigabit ethernet port tests handily at 1Gbps, less a small amount of network overhead.

Available in three colors (silver, space gray, and midnight) the mini-dock is compact at 4.5 by 2.1 by 0.65 inches and 4.25 ounces. It has a 6.7-inch long USB-C cable tail that can’t be removed. The adapter works with an iPad with USB-C as well as Macs; the maximum data rate or resolution of each part of course depends on the particular iPad.

If you wonder about the performance limits of each port without having the manual nearby, the USB-C data ports and the HDMI port have sharply printed text on the metal noting “10Gbps,” “5Gbps,” or “8K/30Hz.” Satechi even got the colors right: the labels are white on the midnight-color adapter and black on the silver and space gray versions. The passthrough power port lacks a note that it can manage up to 85W, but since that’s close to the maximum 100W managed by most older USB-C buses, it doesn’t feel like an oversight.


Should you buy the Satechi USB-C Multiport Adapter 8K with Ethernet V3?

If you own a MacBook Air or MacBook Pro that lacks all the ports you want on demand, you could do no better than this Satechi adapter, particularly at the price. It pairs well with a laptop that docks in a home or office where ethernet, one or more external displays, and other peripherals are available. Adding high-speed USB-C 3.2 ports lets you devote any Thunderbolt 3/4 ports on your Mac to higher-speed purposes.

You would probably find this useful for a Mac mini as well, and potentially for a Mac Studio if you’re filling up USB-C ports or, with two or more displays, want to avoid a standalone USB-C-to-HDMI adapter that takes up an entire connection.

The next step up from this mini-dock of an adapter would be to a powered unit with even more ports and possibilities or to a Thunderbolt mini-dock. Satechi has pushed the limits of a USB-C/USB 3.x/USB4 adapter and met the mark.
