With Thunderbolt ports turning into extra widespread in laptops, a Thunderbolt dock is usually a vital accent. Consider the Thunderbolt dock as a extra highly effective, high-speed different to a USB-C hub, including I/O growth to your laptop computer within the type of additional ports for mice, keyboards, exterior drives, SD playing cards, and, most significantly, shows. It may possibly even cost your laptop computer and smartphone!
Merely put, laptops are slimming down. And within the quest for a “cleaner” look, many laptop computer makers are forgoing the legacy ports (notably within the premium fashions), leaving these duties to exterior units.
The largest distinction between Thunderbolt docks and USB-C hubs are value and bandwidth. USB-C hubs or dongles are far cheaper, however they provide far much less bandwidth. That primarily issues the place show connectivity is worried, however also can have an effect on the quantity and sort of exterior onerous drives, SSDs, and different peripherals that your PC can connect with. Whereas a USB-C hub can assist a single 4K show, typically at an eye-wearying 30Hz refresh charge, Thunderbolt docks can assist as much as two 4K shows at a cushty 60Hz. You can even use Thunderbolt 3 to allow an exterior GPU on your PC. (There’s nothing stopping you from utilizing a USB-C hub with a Thunderbolt dock, both.)
In case your laptop computer features a Thunderbolt port, likelihood is it helps the Thunderbolt 3 or Thunderbolt 4 normal, each of which give 40Gbps. Intel helped launch the up to date Thunderbolt 4 specification in July 2020 as a part of its Eleventh-gen “Tiger Lake” Core laptops, and the specification has change into extra widespread on productiveness laptops. The bandwidth of Thunderbolt 4 is sufficient to drive high-resolution shows and shuttle information backwards and forwards between peripherals with out inflicting your show to flicker or your video stream to stutter.
What’s the distinction between Thunderbolt 3, Thunderbolt 4, and USB4? The straightforward reply is that they’re all extraordinarily related. The longer reply, explaining the variations, could also be discovered inside our Thunderbolt shopping for information beneath our suggestions. If you wish to study extra about the advantages of a Thunderbolt dock, what to search for when shopping for one, or find out how to know whether or not your laptop computer will assist one, you will discover that in our purchasing information, too.
We outline a Thunderbolt dock as one which provides the ports you want for legacy units, like USB-A and HDMI. We outline a Thunderbolt hub as Thunderbolt-in, Thunderbolt-out. The latter is beneficial when you’re among the many small variety of those that personal devoted Thunderbolt shows. (For those who don’t have one, that’s fantastic—simply purchase a Thunderbolt dock as an alternative.)
The most effective Thunderbolt docks
We lead off with our picks for finest finances docks, which usually boast a compact kind issue and simply two show outputs. They’re often bus-powered, which means they’ll require an exterior charger for energy and to energy any linked telephones.
Many of the “full-featured” Thunderbolt docks ship with the type of sizeable energy bricks usually related to gaming laptops. In contrast to our finances choices, these docks are actually desk-bound. Count on the 40Gbps bandwidth widespread to all Thunderbolt 3 docks to be shared amongst a surfeit of ports, together with a number of USB-A ports, a USB-C port or two, SD card slots, and extra. Audio jacks are widespread, and you might even discover an exterior Thunderbolt 3 port as effectively for daisy-chaining further units. All of these ports take up area, so a mannequin that may be positioned on its edge or vertically is best for cramped work surfaces.
IOGear Thunderbolt 3 Journey Dock (GTD300): Greatest finances Thunderbolt dock
Execs
- Fairly compact

Belkin’s Thunderbolt 3 Dock Core arrived in bare-bones packaging, and the product is equally unadorned: It’s a neatly designed “powered” Thunderbolt 3 journey dock.
At an almost sq. 5.2 x 6.5 x 1.5 inches, the Thunderbolt Dock Core black doesn’t take up a lot room, and the included 8-inch Thunderbolt 3 twine gives ample size for flexibility. Ports are adequately spaced out across the flat, black plastic dice, with HDMI 2.0 and DisplayPort 1.4 ports offering a steady 4K/60Hz expertise to each of my 4K shows. There’s gigabit ethernet and a 3.5mm audio jack, however good luck telling the USB 3.1 and USB 2.0 Sort A ports aside—they’re not labeled.
Save for the irritating lack of labels on the USB-A ports, the Dock Core labored as anticipated, with stable efficiency. The plastic shell by no means warmed to worrisome ranges.
There’s one catch: The extra USB-C port on the Dock is a vanilla USB-C port that must be linked to a 60W charger to energy the dock—which isn’t provided. That’s fantastic in case your laptop computer costs with a USB-C charger; if it doesn’t, you’ll want to purchase one. Meaning additional expense and one thing else to hold. In any other case, the dearth of a charger actually saves area whereas on the go.
HP Thunderbolt Dock 120W G4 (4J0A2AA) – Greatest Thunderbolt dock for enterprise
Execs
- Ports aplenty, plus charging
- Strong efficiency
- No thermal considerations
HP sells two variations of this Thunderbolt dock: the 4J0A2AA (this mannequin) and the 4J0G4AA, which we haven’t examined. The distinction is that the 4J0G4AA features a “combo cable” that provides as much as 280W of energy by way of the mixture of a Thunderbolt 4 cable plus a barrel charger, for HP workstations. The 4J0A2AA provides as much as 100W to the host laptop computer by way of the Thunderbolt cable—nonetheless among the many highest we’ve seen. Even then, there have been no thermal points in any respect.
This squat little plastic dice feels much more stable than its rated 1.68lb would point out, and sprouts ports to all sides: a 10Gbps USB-C port able to 15W charging on the entrance, a 5Gbps USB-A port on both aspect plus two extra on the again, all able to 7.5W out.

We solely examined this dock with two 4K/60 exterior shows, however it’s able to driving three 4K/60 shows supplied you could have a DisplayPort 1.4-capable laptop computer with Show Stream Compression, or DSC.
There’s additionally an ethernet port able to 2.5Gbps in addition to one other Thunderbolt 4 port outlet. The ports are crammed along with barely sufficient area for DisplayPort cables or USB keys, however a few the surface ports are barely skewed outwards to supply extra room, a pleasant contact.
This business-oriented dock consists of vPro assist and the facility button/LED can be utilized to show itself on and off —however solely when linked to supported HP notebooks. The throughput is superb, assembly expectations on all the ports. The entrance USB-C port delivered 15W of energy, because the HP’s handbook says it ought to—though, weirdly, the dock misplaced reference to the shows for a number of seconds when a smartphone was linked. We anticipate a firmware improve may clear up these points, and we don’t think about them dealbreakers due to the charging capabilities of the opposite ports. When notified of our findings, HP reps stated they couldn’t reproduce our outcomes.
Kensington SD5700T Thunderbolt 4 Docking Station – Greatest Thunderbolt 4 dock
Execs
- Meets the extra aggressive Thunderbolt 4 specification
- 90W of charging energy
Cons
- The priciest dock we have examined
We actually preferred the construct of the SD5700T, however the value is a bit daunting given the sturdy competitors.
Do you want to purchase a Thunderbolt 4 dock over a Thunderbolt 3 dock? No, probably not. As we clarify in our purchaser’s information beneath, the capabilities of each are largely equivalent. However that is one of the best Thunderbolt 4 dock we’ve seen, if the spec issues to you.

Cons
- Restricted ports
- Greatest for Thunderbolt-attached shows
The Mac world tends to emphasise Thunderbolt-connected shows way over the Home windows world, so this is perhaps a distinct segment product for many of you. However this factor is tiny (4.75 x 2.88 x 0.5in.) even when, sadly, the related energy brick isn’t. It should ship 15W of energy by way of the Thunderbolt/USB-C connections to cost smartphones, and 60W to the host PC.
We lack Thunderbolt-connected shows amongst our take a look at mattress, so we are able to’t absolutely take a look at this. However the field does embrace a USB-C to HDMI adapter, so you’ll be able to actually join one show natively out of the field, then connect a USB-C hub to attach one other. There’s a standalone 10Gbps USB-A port, as effectively. Certain, connecting a second machine seems like a problem—however for Plugable’s value $180 or so, you may find yourself buying and selling saving some money for a bit of additional litter.
Once more, we couldn’t take a look at this dock to its full capabilities. However by way of charging energy and throughput, it lived as much as its specs. The hub did get a bit heat, however its steel building dissipates warmth successfully.

CalDigit Thunderbolt Station 3 Plus (CalDigit TS3 Plus) – Most versatile Thunderbolt dock for I/O
Execs
- Ports, ports, ports
- Vertical orientation, no stand mandatory
Cons
- Solely a single DisplayPort port
CalDigit’s Thunderbolt Station 3 Plus is likely one of the hottest Thunderbolt 3 docks out there, and it’s straightforward to see why: a space-saving vertical orientation, 87W charging, gobs of obtainable ports, and even niceties like a S/PDIF optical connection and an exterior Thunderbolt jack for daisy-chaining units.
The TS3 Plus measures 5.15 x 3.87 x 1.57 inches, and weighs 1.04 kilos. Although it lacks a supporting stand, it rested simply in a vertical place. CalDigit consists of small rubber ft for positioning the aluminum dock in an horizontal orientation.

That’s preferrred for a single 4K show, however awkward for 2. The TS3 Plus consists of one full-sized SD (SD 4.0 UHS-II) card reader, the S/PDIF port, gigabit ethernet, and two 3.5mm audio jacks—one in, one out. 5 USB Sort A ports are additionally included (all 5Gbps USB 3.1 Gen 1) and two USB-C ports (one 5Gbps port, and one 10Gbps port).
To allow two 4K/60 shows, you’ll want a second USB-C dongle working off both the Thunderbolt or USB-C dock—or a forward-looking show with a built-in Thunderbolt/USB-C connector. These are nonetheless uncommon within the Home windows world.
Daisy-chaining the Thunderbolt port to allow a second monitor labored fantastic, although the connection dropped momentarily on each shows when enjoying again video on each shows and transferring recordsdata. In any other case, high-bandwidth video playback went utterly easily. The exterior audio jack additionally didn’t work initially, however did on a subsequent retry. CalDigit’s TS3 Plus barely warmed underneath load.
Thunderbolt dock purchaser’s information
For those who’re on the fence about whether or not a Thunderbolt dock is best for you, figuring out the solutions to the next questions may show you how to.
How do I do know if my laptop computer has Thunderbolt?
The quick reply: Have a look at the laptop computer’s printed specs to make certain. A Thunderbolt port might look indistinguishable from a USB-C port, since they each use the identical bodily USB-C connection. Put one other approach, all Thunderbolt ports are USB-C, however not all USB-C ports are Thunderbolt-equipped.
Thunderbolt ports are supposed to have a small lightning-bolt icon to determine them. However some laptop computer makers use an identical lightning-bolt icon to point {that a} USB-C port can be utilized for charging your cellphone, and not for Thunderbolt. Laptop computer makers generally don’t need to litter the clear strains of their merchandise by including further logos, it appears.
Including to the confusion, you may additionally see USB-C hubs marketed as “Thunderbolt appropriate.” That’s true. You may plug a Thunderbolt dock right into a non-Thunderbolt, generic USB-C port. However will probably be restricted by the out there bandwidth that the port gives, so it’s considerably misleading in that regard.
How briskly is Thunderbolt?
Most USB-C ports are constructed on the second-generation USB 3.1 data-transfer normal, which transfers information at 10Gbps. Most Thunderbolt 3 ports, the commonest normal, switch information at as much as 40Gbps. Thunderbolt 4 differs barely in that it helps a theoretical most of 32Gbps the place information transfers are involved, particularly for exterior storage units.
There are considerably uncommon exceptions: A brand new USB 3.2 Gen 2×2 spec can pair two 10Gbps channels collectively, creating an combination 20Gbps hub. And whereas the overwhelming majority of Thunderbolt 3-equipped laptops are designed with 4 PCIe lanes for a complete of 40Gbps, some laptops solely ship with two PCIe lanes for a complete of 20Gbps. (A Dell assist web page, for instance, particulars its four-lane and two-lane laptops.) Basically, a 20Gbps connection must be sufficient for a single 4K monitor working at 60Hz, with a bit of additional bandwidth for different information transfers amongst linked peripherals.
What’s the distinction between Thunderbolt 3, Thunderbolt 4, and USB4?
The quick reply: Not that a lot, and we think about Thunderbolt 3 docks and Thunderbolt 4 docks to be functionally equal for many customers. The longer reply, which we’ll describe beneath, is that there are variations, and parsing the nuances might be complicated. Consider Thunderbolt 4 because the extra restrictive model of Thunderbolt 3, with little room for any gotchas.
Basically, Thunderbolt 3 and Thunderbolt 4 permit as much as 40Gbps most bandwidth, sufficient for 2 4K/60 shows. “As much as” is the important thing phrase: Thunderbolt 3 is barely required to assist a 10Gbps connection, permitting for a single exterior 4K show (a 16 Gbps PCIe connection, paired with USB3.2). Most producers transcend this, nevertheless, and our really helpful docks assist the complete specification (and two 4K shows) until famous. Thunderbolt 3 additionally helps a slower (16Gbps) PCIe connection for connecting to exterior storage. Except you’re enhancing video or utilizing an exterior GPU, this in all probability received’t matter.
Thunderbolt 4 doesn’t permit for any leeway—you’re getting a full-fledged 40Gbps connection (32 Gbps PCIe + USB 3.2), no questions requested. For exterior storage, Thunderbolt 4 helps 32 Gbps of information switch — once more, this actually solely issues for video, exterior GPU connections, or probably video games. Thunderbolt 4 helps “wake on sleep” from an exterior keyboard or mouse, which lets you faucet your exterior keyboard or wiggle your mouse to wake your PC up, which is useful. Thunderbolt 4 permits for longer cables and extra Thunderbolt ports on laptops, too.
USB4 is basically a subset of Thunderbolt 4, primarily designed as an an I/O specification. USB4 can solely assist one show, and producers can select whether or not it helps a 20Gbps connection or a 40Gbps connection, in keeping with Thunderbolt dock designer Plugable. As a subset of Thunderbolt 4, a USB4 machine will run simply fantastic plugged right into a Thunderbolt 4 port. However a Thunderbolt 4 machine might not work as anticipated when plugged into what’s particularly a USB4 port. Don’t fear about this an excessive amount of, because it’s uncommon to see a USB4 hub. As an alternative, most hubs and docks are marketed as Thunderbolt 4, whereas most units (like an exterior SSD) are designed round USB4.
Be aware that Thunderbolt 3 and 4 require not less than 15W to energy units plugged into the Thunderbolt port, comparable to a bus-powered onerous drive. USB4 requires simply half that.
Machine maker Anker has a pleasant abstract of all the technical options related to Thunderbolt 3, Thunderbolt 4, and USB4, when you actually need to get into the fantastic distinctions.
Anker
Nearly each Thunderbolt machine will ship with its personal cable. We’d advocate that you simply use Thunderbolt 3 cables with Thunderbolt 3 merchandise, and Thunderbolt 4 cables with Thunderbolt 4 merchandise.
What to search for in a Thunderbolt dock
Ports, cables, peripherals: These are the three main issues when shopping for a Thunderbolt dock.
We’re starting to see the Thunderbolt dock market break down into a number of alternative ways. First, there’s the finances versus full-featured docks we’ve highlighted above. However you additionally might even see one thing much like the USB hubs of outdated, too: Gadgets that take Thunderbolt in after which present a number of USB-C (together with Thunderbolt) ports out. There are a small variety of shows with Thunderbolt inputs, which might be plugged immediately into these hubs. Do you could have an current low cost USB-C dongle? You may actually plug that in right into a Thunderbolt dock and add much more I/O performance.
Principally, think about what you’ll need to plug into the dock as a information for getting one. We choose units with ports in-built (comparable to HDMI, USB-A, and so forth) because the USB-C machine ecosystem remains to be in its infancy. However ask your self some questions. Would you like a primary Thunderbolt dock, with only a pair of HDMI ports for connecting two shows? Does an SD card slot matter? What number of USB Sort A peripherals do you intend to connect? Do you need to use the Thunderbolt cable to cost your laptop computer, too?
Cables might be an unexpectedly necessary consideration, too. Nearly each dock ships with a Thunderbolt cable. However think about the shows you personal (sometimes HDMI or DisplayPort) and think about whether or not the dock will accommodate them.
Verify your laptop computer’s energy provide. Does it plug into your laptop computer by way of USB-C? In that case, a Thunderbolt dock will seemingly energy it. You’ll want to know how the dock provides energy, although. Verify your laptop computer’s charger to learn the way a lot energy it provides, and the way a lot the dock might want to provide to exchange it. In case your laptop computer or units aren’t receiving sufficient energy, you might even see a warning pop up.
A “bus-powered” dock received’t include an exterior charger within the bundle, saving some value, area, and energy considerations. A dock with “energy supply” will provide its personal energy and cost your laptop computer and/or a cellphone by way of your laptop computer’s current USB-C charger. (Likelihood is that it received’t supply the quick-charging capabilities premium smartphones supply, although.) The extra energy your dock provides, the better the flexibility to cost your laptop computer and any bus-powered units. It is a gotcha most individuals don’t take into consideration, so when you plan to attach a number of bus-powered onerous drives or SSDs, purchase a dock with a hefty energy provide. (USB keys, however, require tiny quantities of energy. Don’t fear about these.)
There’s yet another consideration: the size of the Thunderbolt cable between your laptop computer and the dock itself. You’ll have seen or heard about USB-C ports carrying out on smartphones; a free or wobbly connector on Thunderbolt docks could cause displays to unexpectedly flicker or lose connection. Take into account how a lot stress can be placed on a cable. A Thunderbolt dock that’s dangling from a Thunderbolt port will stress the bodily connector. You don’t need that!
For those who’re a Mac consumer who has stumbled throughout this text, welcome. However please bear in mind that early Apple MacBook Execs powered by Intel silicon supported as much as two 4K shows. The primary MacBook Execs powered by the Apple M1 chip solely assist a single 4K show. Many Mac customers have just lately left adverse evaluations on Thunderbolt docks on buying websites due to this. Purchase a PC!
How we examined
We’re working from the premise that you simply’re shopping for a Thunderbolt dock for its distinctive skill to connect with two 4K displays at 60Hz. Decrease resolutions must be a lot simpler to run efficiently. Our first take a look at merely linked every dock to a pair of 4K/60Hz shows, every of which may settle for DisplayPort and HDMI cabling, and made positive there have been no visible artifacts at 60Hz decision.
Second, we checked to see whether or not the out there ports delivered the bandwidth we’d anticipate, connecting them to an exterior SSD and transferring a group of take a look at recordsdata over the Thunderbolt cable and port. We additionally used AJA’s System Check software to double-check our numbers and take a look at whether or not learn and write speeds have been constant.
Lastly, we spot-checked the out there energy draw of the hubs and ports with a USB energy meter, in addition to merely connecting them to bus-powered units to see if they might ship sufficient energy to permit them to function. Right here, we found that one in all our testing laptops didn’t provide sufficient energy working on battery to energy a bus-powered Thunderbolt dock, so we enlisted a second, totally different laptop computer as a backup.
This story was up to date on Might 30 with new data and product suggestions. A few of our suggestions are primarily based on Thunderbolt dock evaluations produced by our sister web site, TechAdvisor.co.uk, and authored by Simon Jary.
