Over the past few months, I've taken a look at a number of Thunderbolt 3 docks that all hit the market around the same time, including models from OWC, CalDigit, Belkin, and Kensington. There's at least one more major player in the market, so today I'm sharing my thoughts on Elgato's $300 Thunderbolt 3 Dock. Elgato's dock has a lot in common with many of its competitors, including a slim horizontal design of brushed aluminum and plastic, an array of ports for expanding the capabilities of your Thunderbolt 3-equipped Mac, and more.

The dock looks nice on a desk, with a black matte plastic front and back wrapped by a brushed aluminum enclosure that's rounded around the sides. A small Elgato wordmark is printed in the front left corner of the dock's top, but it doesn't mar the overall look of the accessory, which remains rather unobtrusive. Measuring just under 8 inches wide, Elgato's dock is slightly narrower than some of the other docks, which to my eye makes it look a bit better sitting on the foot of my LG UltraFine 5K display. Belkin's dock at a little over 8 inches also fits pretty well, but wider docks like OWC's and Kensington's overhang a bit.

Of course, everyone's desk setup is different so variations of around an inch in the width of all of these docks may not be a deal-breaker, but it's worth noting this is the narrowest of the horizontal designs I've tested. At about 3.15 inches deep and an inch high, Elgato's dock is otherwise pretty much on par with competing docks in terms of size.

While the dock itself is slim and weighs just over two thirds of a pound, as with competing docks it has a large external power brick. In fact, it's the exact same power brick used by Belkin and Kensington, but with a small Elgato mark stamped into the top. A 0.5-meter Thunderbolt 3 cable is also included in the box.

Unlike most other docks, Elgato's does not include any LEDs to show whether or not it has an active connection to power or a computer. It's not really an issue, as for the most part a dock is meant to just work when it's plugged in and it's easy to tell whether or not that's the case.

Matching what is becoming standard for the latest docks, Elgato's Thunderbolt 3 Dock supports up to 85 watts of charging power, letting you power even a 15-inch MacBook Pro over the same cable used to transfer data and eliminating the need for a separate power adapter while connected to the dock. Docks such as OWC's at 60 watts may be unable to keep up with the power demands of a 15-inch MacBook Pro under heavy load.

Elgato's dock also has roughly a standard set of ports, with a single USB 3.0 (5 Mbps) Type-A port and a pair of 3.5 mm audio jacks (one mono mic input and one amplified analog stereo output) on the front for easy access. The rear of the dock includes a Gigabit Ethernet port, two more USB 3.0 Type-A ports, a pair of Thunderbolt 3 ports, and a DisplayPort port. My usual complaint of wanting more USB ports such as the five offered on OWC's dock still stands here, but three is the number just about every other manufacturer is going with.

Unlike many other docks, Elgato's supports standalone USB charging, so an iPhone, Apple Watch, or other accessory connected via USB will continue to charge even if the dock isn't connected to a computer or a connected computer is turned off.

I ran a few speed tests using Elgato's dock paired with CalDigit's 10 Gbps USB 3.1 Gen 2 Tuff external SSD and found speeds of around 345 MB/s read and 325 MB/s write through the Type-A USB 3.0 port, which is pretty typical for docks like this but a bit slower than connecting directly to a computer via USB 3.0.

Connecting the drive to one of the dock's Thunderbolt 3 ports using USB-C yielded read and write speeds of around 500 MB/s and 460 MB/s respectively, which is pretty close to the 505/485 MB/s speeds seen connecting directly to a 10 Gbps MacBook Pro. Of course, connecting a drive this way means you no longer have a Thunderbolt 3/USB-C port available for an external display if your setup requires it.

Using a combination of Thunderbolt 3/USB-C, DisplayPort, and appropriate adapters, Elgato's dock can support a single 5K display at 60 Hz or a pair of up to 4K displays at 60 Hz. Elgato has a support document outlining the various display configurations that can be used with the dock.

While Elgato's Thunderbolt 3 Dock works out of the box without the need for any drivers or other software, Elgato does offer a Thunderbolt Dock Utility to add some additional functionality. The utility runs as a simple menu bar app that makes it easy to eject any drives connected to the dock before manually disconnecting them or the dock.

The utility also enables high-power USB support that bumps all USB 3.0 ports to 1.5 A for faster charging while also adding support for Apple's external USB SuperDrive. Once enabled by the utility, high-speed charging does not require the utility to be running and also works if the host computer is sleeping.

At a list price of $300, Elgato's Thunderbolt 3 Dock is competitive with other docks such as CalDigit's TS3 and OWC's dock. Belkin and Kensington come in at $50 more for their docks. At the $300 price point, it would be nice to see some additional features such as more USB ports or an SD card slot. Certain customers might also appreciate eSATA or FireWire ports that are offered by some competitors, although usage of these interfaces continues to shrink.

Elgato's Thunderbolt 3 Dock is available now from Amazon.

Why not just build these ports into the computer in the first place?

I can't call them recommendations since I've never tried them, but here's one my friend sent me: https://www.amazon.com/QacQoc-Aluminum-Thunderbolt-Pass-Through-Charging/dp/B0722Y9SZ8
Amazon has plenty of others if you search, all under $100. If I were looking for one, I'd just buy whatever is the most popular (with good reviews) on Amazon.
that's not even thunderbolt.
