Why I like the Plugable TBT3-UDZ

Plugable’s TBT3-UDZ has at various times been my best overall and runner-up, depending on price swings. Because of the similarities between Thunderbolt 3 and Thunderbolt 4, there’s no harm in buying a Thunderbolt 3 dock, as the performance is the same. But (for now, anyway), the Plugable TBT3-UDZ is just a few dollars more expensive than our runner-up pick, the Kensington SD5780T, and is far more flexible in terms of what it of what it offers. Plugable’s dock simply offers much more flexibility for a comparable price.

Put simply, the TBT3-UDZ is in a class of premium docks that don’t force you to pick a particular display cable — if you own a pair of monitors with DisplayPort cables, you can plug them right in. Oh, they’re HDMI? No problem — there are two ports for those, too. Powered ports to charge a smartphone? Sure. SD and microSD slots? Of course. And a vertical stand to save space? Sign me up.

Plugable also has a reputation for bulletproof customer service, too, which goes far in helping me recommend this dock.

Who should buy the Plugable TBT3-UDZ

Our best picks are designed for everyone, but this dock offers the most value of our top two recommendations. If you have an existing display cable to connect to a monitor or two, you have everything you need. It’s a no-fuss solution.

This dock works best on a desktop, as part of a permanent docking station. We’d also recommend the TBT3-UDZ for those who want to save a bit of desk space, as that vertical stand can be slipped next to a display to save space.

Why I like the Kensington SD5780T

One of my testing credoes is “affordable flexibility,” and I favor a dock that will fit into your existing setup. Plugable’s TBT3-UDZ, above, is about as flexible as you can get, but the Kensington SD5780T was originally substantially cheaper. Not any more, which is why I’ve elevated the TBT3-UDZ to “best pick” status.

The Kensington SD578T, however, is a solid all-around Thunderbolt 4 dock in all respects. For those who wish to use a single 4K monitor, chances are that you’ll already own an HDMI cable. The additional Thunderbolt 4 port allows you to add an additional display, but that requires the purchase of an additional cable. Still, in my tests the dock was stable (and not all are!) with a nice port selection. The dock will charge your smartphone, albeit with a USB-A port.

I really like the Anker 568 as a second runner-up, with a marvelous collection of features for an affordable price.

Who should buy the Kensington SD5780T

The SD5780T is an ideal “starter” dock, for someone who has a laptop and a single external display and might want to add more in the future. Adding a second display will require the purchase of a USB-C (Thunderbolt) to HDMI cable, which will cost an additional $20 or so. The inclusion of the SD card slot should appeal to photographers who record photo or video on those cards.

Why I like the Belkin Thunderbolt 3 Dock Core

Belkin’s Thunderbolt 3 Dock Core is a smartly designed “powered” Thunderbolt 3 travel dock, and an inexpensive one as well. It’s one of the most compact Thunderbolt docks that you can buy.

At a nearly square 5.2 x 6.5 x 1.5 inches, the Thunderbolt Dock Core doesn’t take up much room, and the included 8-inch Thunderbolt 3 cord provides ample length for flexibility. Ports are adequately spaced around the flat, black plastic cube, with HDMI 2.0 and DisplayPort 1.4 ports providing a stable 4K/60Hz experience to both of my 4K displays. There’s Gigabit Ethernet and a 3.5mm audio jack. Unfortunately, the USB 3.1 and USB 2.0 Type A ports aren’t labeled, but they’re there.

Amazon almost always has this dock on a big sale, so it’s an inexpensive option for most people, too.

Who should buy the Belkin Thunderbolt 3 Dock Core

If you’re a traveler and don’t exactly know where you’ll end up working, Belkin’s dock is a good failsafe. I usually stick it in my bag when I’m on the road, just in case. The only real kicker that you have to watch out for it is the lack of a powered charger. That can result in some peripherals not receiving as much power as they should.

The squarish, “star” design is quite nice for working at a small hotel desk, though.

Why I like the Ugreen Revodok Pro 13-in-1 Triple Display Docking Station

The only reason that this isn’t my pick for the best budget Thunderbolt docking station is because it appears to use a generic form of compression known as HBR3 (High Bit Rate 3) with DSC (Display Stream Compression), which is built into the DisplayPort spec. That’s a particular technology that is more common within recent Intel Core (and Core Ultra) laptops, but isn’t guaranteed to appear on yours. (If you own a laptop with a Thunderbolt port, though, this should work just fine.) You’ll also have to supply your own USB-C power cable.

Otherwise, this docking station has so much to offer. The price is outstanding, of course, but Ugreen’s dock is also so flexible yet so stable. Everything’s well labeled, and the dock offers DisplayPort as well as HDMI options. And it’s really quite portable, too. Just remember that charger.

Who should buy the Ugreen Revodok Pro 13-in-1 Triple Display Docking Station

It’s interesting that both of our budget picks cater to budget shoppers as well as travelers, as both are compact and relatively lightweight. But I’d really recommend this dock for those who own laptops with 13th-gen Core hardware or above. HBR3/DSC technology really doesn’t work on older systems like 11th-gen Core hardware and older PCs. If you own an AMD Ryzen laptop, too, it may be a little iffy.

Why I like the Kensington Thunderbolt 4/USB 4 Quad Video Docking Station (SD5800T)

I ultimately ruled out the SD5800T as a candidate for the best overall Thunderbolt dock because the price is all over the map: $379 is way too much, but Amazon’s $229.99 price makes this a bargain for what this 16-in-1 dock delivers. Like the Plugable TBT3-UDZ above, this dock features four display ports (two DisplayPort, two HDMI) with a twist — it can connect to all four displays at 4K resolution, and not just two. (Sonnet’s Echo 20 Thunderbolt 4 SuperDock has its own gimmick, which I considered but ruled out: an integrated M.2 storage slot.)

The dock can support four displays by using the CDC/HBR3 data compression technique mentioned elsewhere, which modern laptops include but older laptops do not. For me, this quad-display capability is a bonus, and it will handle the expected two 4K displays just fine, and at a reasonable price. About the only thing I didn’t like was that one charging port didn’t work as expected. But it has a spare, too! — and that worked as expected. This is a solid, ultra-premium dock at a good price, which is why it earns my endorsement. A vertical stand helps save space.

Who should buy the Kensington Thunderbolt 4/USB 4 Quad Video Docking Station (SD5800T)

Thunderbolt 4 and USB4 are basically identical, which Kensington calls out in its name. Any laptop owner could buy this dock. Nevertheless, the flexibility may be overkill for some, and only a small fraction of buyers will want to connect four separate displays to this dock. Unless you’re worried about Thunderbolt 5 (and a enthusiast buyer of the SD5800T may be) this is an investment that should hold up for several years.

Why I like the Razer Thunderbolt 4 Dock Chroma

I was surprised by how much I like this dock. Still, I agonized over this pick. OWC’s Thunderbolt Go Dock was our prior pick, and I liked its gimmick: an integrated power brick that allows it to be taken on the road, sort of. Razer’s Chroma dock also has a gimmick: its RGB. But this dock also forces you to buy extra display cables if you want to connect two 4K displays, which normally turns me off. As one of the more modern docks, with rock-solid stability, it won me over in the end, though its storage performance was middling.

The RGB lighting is fun, and optional — it can be turned off. Overall, the Chroma is the better dock, but if you don’t want to spend the extra money, consider OWC’s dock instead. Frankly, the Kensington SD5780T top pick runner-up shares a lot of the same functionality as both the OWC and the Razer docks, so price plays a factor here.

Who should buy the Razer Thunderbolt 4 Dock Chroma

Gamers, obviously. But even a stodgy old reporter like me likes it, because the RGB can either be fixed to a certain color or turned off entirely. And the dock surprised me with its stability and construction. You can certainly buy this dock for its blingy aesthetic, but it works just as well as a more down-to-earth alternative, too. Razer did a very nice job balancing both aspects.

Why I like the Plugable 5-in-1 Thunderbolt Hub (USB4-HUB3A)

How does a Thunderbolt hub differ from a Thunderbolt dock? In this case, there’s less of an emphasis on legacy ports, and more of a focus on a direct connection to a display. The Mac world tends to emphasize Thunderbolt-connected displays far more than the Windows world does, so this might be a niche product for most of you. But this thing is tiny (4.75 x 2.88 x 0.5 inches) even if, unfortunately, the associated power brick isn’t.

It will send 15W of power via the Thunderbolt/USB-C connections to charge smartphones, and 60W to the host PC.

If you don’t need a big, bulky dock with multiple connections, Plugable’s 5-in-1 Hub just does the job and without any extra fuss. If your laptop needs more power than the 60W Plugable hub provides, then I would recommend the Satechi Thunderbolt 4 Slim Hub Pro instead.

Who should buy the Plugable 5-in-1 Thunderbolt Hub (USB4-HUB3A)

Thunderbolt displays are prevalent in the Mac market, but this hub can be used for an emerging market of Thunderbolt/USB-C monitors. They’ll likely become more prevalent in the future.

But connecting a cable from each port on your laptop to each display is messy. You’d still like just one. The hub works as a “splitter” of sorts for the Thunderbolt connection.

Put another way, if you own a USB-C monitor, those displays tend to also have legacy ports (USB-A, USB-C) inside them, which means that a Thunderbolt dock and its cluster of ports may be redundant. This hub is a way to save a little money for the user who has a specific setup.

Why I like the Anker 568 USB-C Docking Station

Two power ports on the front: They’re a delightful little detail that I wish other vendors would adopt as well. As you may have read elsewhere in this roundup, USB4 and Thunderbolt4 are basically identical, so you might be wondering why we’re even separating out this category. Well, if you’re a notebook owner with an AMD Ryzen chip inside, you might be looking for dedicated dock, and this is a very good one. Quite frankly, this Anker 568 is in the running for the best overall docking station.

This 11-in-1 docking station favors DisplayPort, with two DisplayPort 1.4 ports, and a single HDMI 2.0 video port. The Anker 568’s distinguishing feature, however, is the pair of 10Gbps USB-C ports on the front, each supplying 30W of power as well as a separate 100W connection to the laptop. That’s quite unusual, and the two ports should fast-charge a smartphone and possibly even a tablet.

Who should buy the Anker 568 USB-C Docking Station

If you own a notebook with a Ryzen CPU inside, and you want the confidence that this dock has been tested to ensure USB4 compatibility, this is the dock for you. You’ll also want to buy it if you charge multiple phones or use high-powered peripherals, such as a high-end SSD.

I really like this dock, and I’d recommend it to about anyone. It does lack microSD and SD card slots, though, which may rule it out for photographers.

Why I like the Plugable USB4 Dual HDMI Docking Station (UD-4VPD)

Plugable’s dock claims dual 4K120 capability, which unfortunately I wasn’t able to test at the time of the review. But the dock offered a stable connection to the connected devices, with the ability to charge smartphones as well. Anker’s 568 dock edges it out in price and slightly in display flexibility, but lacks the SD card slot that the Plugable includes.

Who should buy the Plugable USB4 Dual HDMI Docking Station (UD-4VPD)?

This is a general-purpose USB4 dock, which can be adopted by anyone. But it’s best suited for laptops with a Ryzen chip inside, and for photographers that need the SD card slots that the Anker 568 doesn’t provide.

Why I liked the Ugreen 9-in-1 USB-C (Revodok) Docking Station CM615

Like some of our premium Thunderbolt docks, Ugreen provides options to use either HDMI or DisplayPort to connect a display, allowing you to use your existing display cables and save some money.

Like most DisplayLink docks, this dock was unusually stable, with no flickering between displays — one of the reasons I like DisplayLink docks. Some other Thunderbolt docks offer the same flexibility to shift between monitors, but not many. Ugreen’s dock does so affordably.

If you’re not worried about hunting down the proper software driver (because Ugreen, bless them, does not make it apparent that it needs one) than I would recommend that you buy this dock. It offers many of the features of more expensive Thunderbolt docks at an affordable price.

Why I liked the Sonnet Echo 13 Triple 4K Display Dock

Sonnet’s Echo 13 Triple 4K Display Dock follows the intriguing path other DisplayLink docks have blazed: The dock’s built-in compression means you can connect to three 4K displays, without penalty. And yes, it works as advertised, though with one issue that holds it back: spotty audio that really needs to be fixed. (If you use your laptop’s headphone jack, there’s no issue.)

There was a tiny bit of instability, but performance was excellent. And with 20W of charging power for your phone and 100W for your laptop, you’ll be able to power a wider range of notebook options.

Who should buy the Sonnet Echo 13 Triple 4K Display Dock

The price differential between the Sonnet and Ugreen docks should help answer that question: The Sonnet buyer is willing to pay a little more for what is really a well-made and well-documented dock, with clear instructions. Really, without the price differential and the audio issues, this would be the top dock in the category.

The short answer: Look at the laptop’s published specifications to be sure. A Thunderbolt port may look indistinguishable from a USB-C port, since they both use the same physical USB-C connection. Put another way, all Thunderbolt ports are USB-C, but not all USB-C ports are Thunderbolt-equipped.

Thunderbolt ports are supposed to have a small lightning-bolt icon to identify them. But some laptop makers use a similar lightning-bolt icon to indicate that a USB-C port can be used for charging your phone, and not for Thunderbolt. Laptop makers sometimes don’t want to clutter the clean lines of their products by adding additional logos, it seems. Fortunately, most laptops now choose to highlight their Thunderbolt capabilities, so the ports should be well-marked.

You may also see USB-C hubs marketed as “Thunderbolt compatible.” That’s true. You can plug a Thunderbolt dock into a non-Thunderbolt, generic USB-C port. But it will be limited by the available bandwidth that the port provides, so it’s somewhat deceptive in that regard. 

A 10Gbps USB-C dongle won’t replace a 40Gbps Thunderbolt dock, as there’s circuitry within the dock that allows it to work with your laptop’s high-speed Thunderbolt port. However, there’s nothing saying that you can’t connect the dongle to an available USB-C port on the Thunderbolt dock itself to add even more ports. If your laptop has two Thunderbolt ports, you can also attach a Thunderbolt dock to one port, and the dongle to the other.

That solution will add more clutter to your desk, but it might allow you to buy a cheaper, budget dock, too. It’s up to you!

Put simply, 40Gbps.

Most USB-C ports are built on the second-generation USB 3.1 data-transfer standard, which transfers data at 10Gbps. Thunderbolt 3 and 4 ports, the most common standard, transfer data at up to 40Gbps. Thunderbolt 4 differs very slightly in that it supports a theoretical maximum of 32Gbps for external storage devices, but you probably won’t notice the difference.

Intel is expected to unveil an 80Gbps version of Thunderbolt this year, called Thunderbolt 5, meaning that you’ll see even Thunderbolt docks with even more capabilities when devices release in 2024.

There are some exceptions, which you can largely ignore. A new USB 3.2 Gen 2×2 spec can pair two 10Gbps channels together, creating an aggregate 20Gbps hub. (This is really only for external gaming-class SSDs.) And while the vast majority of Thunderbolt 3-equipped laptops are designed with four PCIe lanes for a total of 40Gbps, some laptops only ship with two PCIe lanes for a total of 20Gbps. (A Dell support page, for example, details its four-lane and two-lane laptops.) Essentially, a 20Gbps connection should be enough for a single 4K monitor running at 60Hz, with a bit of extra bandwidth for other data transfers among connected peripherals.)

Intel’s 10th-gen and 11th-gen Core chips launched in the early days of Thunderbolt, and company representatives say that you can depend on them for 32Gbps of data, not a full 40Gbps. Intel’s 12th-gen and 13th-gen Core chips offer the most consistent Thunderbolt experience, with 40Mbps Thunderbolt 4 speeds, including 32Gbps for data transfers to and from storage devices.

The short answer: Not that much! Thunderbolt 3 and 4 are functionally equivalent, transferring data at 40Gbps.

Thunderbolt 5 is the 80Gbps version, but it will be backwards compatible with both Thunderbolt 3 and 4. You won’t see it until 2024, however. (If you own a laptop with a Thunderbolt 4 port, you’ll be able to use with a Thunderbolt 5 dock, Intel says. The only wrinkle is that a Thunderbolt 4 laptops will only pass data at its rated speed of 40Gbps.)

For the sake of completeness, we’re going to detail some of the differences below. But if you’re new to this, let us reiterate: Thunderbolt 3 and 4 are basically the same, and Thunderbolt 5 won’t be an issue until 2024. Don’t sweat the details.

Think of Thunderbolt 4 as the more restrictive version of Thunderbolt 3, with less room for any gotchas.

Essentially, Thunderbolt 3 and Thunderbolt 4 allow up to 40Gbps maximum bandwidth, enough for two 4K/60 displays. “Up to” is the key phrase: Thunderbolt 3 is only required to support a 10Gbps connection, allowing for a single external 4K display (a 16Gbps PCIe connection, paired with USB 3.2). Most manufacturers go beyond this, however, and our recommended docks support the full 40Gbps specification (and two 4K displays) unless noted. Thunderbolt 3 also supports a slower (16Gbps) PCIe connection for connecting to external storage.

Thunderbolt 3 is also the only specification (not Thunderbolt 4) that we’ve seen connecting to external GPUs, in case you’d like to try that approach.

Thunderbolt 4 doesn’t allow for any leeway—you’re getting a full-fledged 40Gbps connection (32Gbps PCIe + USB 3.2), no questions asked. For external storage, Thunderbolt 4 supports 32Gbps of data transfer—this really only matters for video, external GPU connections, or possibly games. Thunderbolt 4 supports “wake on sleep” from an external keyboard or mouse, which allows you to tap your external keyboard or wiggle your mouse to wake up your PC, which is handy. Thunderbolt 4 allows for longer cables and more Thunderbolt ports on laptops, too.

Device maker Anker has a nice summary of all of the technical features associated with Thunderbolt 3, Thunderbolt 4, and USB4, if you really want to get into the fine distinctions (below). What’s USB4? We address that in the next question.

Probably. USB4 ports typically appear on laptops with AMD Ryzen processors inside. USB4 and Thunderbolt 4 are compatible and functionally equivalent. (Though Thunderbolt is an open standard, Intel declines to certify non-Intel hardware. That means that Ryzen laptops end up with USB4 ports, and Intel Core laptops include Thunderbolt.)

USB4 is essentially a subset of Thunderbolt 4, mainly designed as an an I/O specification.

As a subset of Thunderbolt 4, a USB4 device will run just fine plugged into a Thunderbolt 4 port. But dock makers tell us that a Thunderbolt 4 device may not work as expected when plugged into what is specifically a USB4 port. Instead, most hubs and docks are marketed as Thunderbolt 4, while most devices (like an external SSD) are designed around USB4. (We test Thunderbolt docks on Thunderbolt laptops.) There are USB4 docks, however, which you’ll find in our list of best picks, which we’ve also tested.

USB4 Version 2 is an upcoming standard that will propel USB4 to 80Gbps, just like Thunderbolt 5. The first products will debut (at a guess) in early 2024, but the USB-IO hasn’t given us an exact timeline or the capabilities of USB4V2 docks.

Note that Thunderbolt 3 and 4 require at least 15W to power devices plugged into the Thunderbolt port, such as a bus-powered hard drive. USB4 requires just half that.

Thunderbolt 5 will debut in 2024, both in laptops as well as docks and devices. Although we saw a couple of early products at CES 2024, we don’t expect devices until the second half of the year.

The Thunderbolt 5 spec pushes I/O bandwidth from 40Gbps in Thunderbolt 4 to 80Gbps in Thunderbolt 5, and even to 120Gbps in some cases. Another good way to think of Thunderbolt 5 is in the context of what it can do. Thunderbolt 4 allows enough bandwidth for two 4K displays, running at 60Hz. Thunderbolt 5 will offer enough bandwidth to connect to three 4K displays, at 144Hz apiece. That helps make Thunderbolt 5 a gaming-class technology, rather than just for office work.

Thunderbolt 5 will also allow for 64Gbps of dedicated bandwidth for storage and external GPUs, double the 32Gbps on Thunderbolt 4.

Finally, there’s power. Thunderbolt 5 will provide up to 240W (140W required) of charging power for your laptop. Most laptops require 65W to 90W today, but gaming laptops require more. All this means is that a Thunderbolt 5 dock will potentially eliminate the need to carry a gaming laptop’s charger around. (It won’t be in all cases, but some.)

A DisplayLink USB-C docking station is a new category of docking station. They’re often marketed just as a USB-C docking station, unfortunately, though the DisplayLink logo features prominently on the box. The key here is that the DisplayLink technology (now owned by Synaptics) uses data compression between your PC and the dock to approximate a Thunderbolt experience (a pair of 4K displays at 60Hz, plus additional peripherals) across the narrower, slower USB-C bus. You’ll need to install a software driver for your PC to communicate with the DisplayLink chip built into the dock.

The advantage here is twofold. First, DisplayLink allows you to “cheat” and get a Thunderbolt dock experience on an older laptop. Alternatively, even if you do own a laptop with a Thunderbolt port, you may be able to find a DisplayLink USB-C dock for a cheaper price than Thunderbolt. This is a viable solution, especially if you don’t mind not playing PC games.

Our separate story on DisplayLink docks has more.

We’re starting to see some USB-C docking stations take advantage of another technology: HBR3 (High Bit Rate 3) with DSC (Display Stream Compression). Think of it as the industry-standard, manufacturer-agnostic version of DisplayLink. It works over the USB-C port, and again provides a dual 4K60 display experience.

The problem? It’s wonky. We’ve found that support for the technology was very iffy in 11th-gen hardware, and really seems to work consistently in 12th-gen or 13th-gen Core laptops (and above, when they ship). While we can’t really recommend it right now, we’re keeping an eye on it.

Yes, you can. Certain manufacturers (Razer is one, though there are others) have built enclosures that can house a standard desktop graphics card, connected to your laptop via a Thunderbolt cable. Although a mobile gaming laptop with an external GPU does a good job enabling mobile gaming, a desktop GPU does even better. Thunderbolt simply connects the two.

However, we would recommend using a Thunderbolt 3 dock instead, or wait until Thunderbolt 5. How can you hook up an external GPU to your laptop via Thunderbolt? Our story has more.

According to a representative for Razer, the differences between Thunderbolt 3 and Thunderbolt 4 were too small. “When we release any product, we only do so when there can be a material advantage over the previous generation,” we were told.

Since Thunderbolt 4 was backwards compatible and functionally equivalent to Thunderbolt 3, Razer simply declined to invest in the production and testing of a Thunderbolt 4 eGPU. We presume other manufacturers followed suit.
