With Thunderbolt ports changing into extra widespread in laptops, a Thunderbolt dock is usually a crucial accent. Consider the Thunderbolt dock as a extra highly effective, high-speed various to a USB-C hub, including I/O growth to your laptop computer within the type of further ports for mice, keyboards, exterior drives, SD playing cards, and, most significantly, shows. It will probably 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 most important 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 can even have an effect on the quantity and sort of exterior onerous drives, SSDs, and different peripherals that your PC can hook up with. Whereas a USB-C hub can assist a single 4K show, typically at an eye-wearying 30Hz refresh price, Thunderbolt docks can assist as much as two 4K shows at a cushty 60Hz. You too can use Thunderbolt 3 to enable an external GPU in 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, chances are high it helps the Thunderbolt 3 or Thunderbolt 4 normal, each of which give 40Gbps. Intel helped launch the updated Thunderbolt 4 specification in July 2020 as a part of its Eleventh-gen “Tiger Lake” Core laptops, and the specification has turn into extra common on productiveness laptops. The bandwidth of Thunderbolt 4 is sufficient to drive high-resolution shows and shuttle knowledge 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 comparable. The longer reply, explaining the variations, could also be discovered inside our Thunderbolt shopping for information beneath our suggestions. If you wish to be taught extra about the advantages of a Thunderbolt dock, what to search for when shopping for one, or the best way to know whether or not your laptop computer will assist one, yow 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 for those who’re among the many small variety of those that personal devoted Thunderbolt shows. (In case you don’t have one, that’s nice—simply purchase a Thunderbolt dock as a substitute.)
The very best Thunderbolt docks
We lead off with our picks for greatest funds docks, which usually boast a compact type issue and simply two show outputs. They’re normally bus-powered, that means they’ll require an exterior charger for energy and to energy any related 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 funds choices, these docks are actually desk-bound. Anticipate 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 nicely for daisy-chaining extra units. All of these ports take up area, so a mannequin that may be positioned on its edge or vertically is healthier for cramped work surfaces.
IOGear Quantum Twin Mode Thunderbolt 3 Dock Professional (GTD737) – Greatest funds Thunderbolt dock
Execs
- Nice mixture of options
- Funds value
- 60W of passthrough charging energy
Cons
- Two DisplayPort ports restrict show I/O choices
- Could be tough to seek out in shops
About the one knock in opposition to IOgear’s GTD737 is its use of two DisplayPort 1.2 ports on the rear of the dock, which function the one devoted show outputs. (We suspect HDMI is extra common.) In our testing, an HDMI-to-DisplayPort adapter didn’t work, both, which implies that you’ll should personal a show with this port connection.
In any other case, this dock is superb, offering nearly all of the options you’ll need at an inexpensive value: a 10Gbps USB-A port on the entrance for 7.5W smartphone charging; on the rear, two 5Gbps USB-A ports for legacy mice and keyboards and two 10Gbps USB-C ports for additional growth. There’s additionally a gigabit ethernet port and a headphone jack. The two.3-foot Thunderbolt 3 cable provides 60W in your laptop computer by way of the related 135W energy brick.
The efficiency was rather less than we anticipated, dropping 1 p.c of the frames in our 4K YouTube take a look at—a little bit of jitter that was noticeable, although not annoying. The dock warmed beneath load, however by no means received scorching. On one event, one of many USB-C ports didn’t acknowledge our take a look at SSD, however powering the dock on and off solved the issue.
If the DisplayPort situation isn’t a priority and also you don’t thoughts an influence brick, this IOgear dock is an superb funds alternative.

The Thunderbolt 3 dock is bus-powered, nevertheless, which implies you’ll need your laptop computer to be plugged in for greatest outcomes, although the hub itself doesn’t require its personal charger.
IOgear’s plastic dock measures simply 2.2 x 0.91 x 4.06 inches, and is among the many smallest we’ve examined, so it neatly matches right into a backpack for journey. On its underside, a inexperienced plastic shell conceals a nook to retailer the dock’s quick, 5-inch twine when not in use.
Ports are minimal: one HDMI 2.0 port, one DisplayPort 1.2 port, one 5Gbps USB-A port, and gigabit ethernet port. In case you’re okay utilizing the USB port for a mouse or keyboard, moderately than for high-speed exterior storage, the GTD300 will go well with you nice. (After all, we’d have most well-liked a 10Gbps port, at the very least.) The slight lack of I/O flexibility knocks this down a notch.
A few of Amazon’s customer reviews are barely complicated: In our expertise the ethernet port labored as anticipated, as did the USB-A port. Maybe due to the small type issue, the GTD300 will get noticeably scorching, however not uncomfortably so in our opinion.

On one event the dock stopped working, however resumed working a second time after we plugged it in per week or so later. This looks as if an in any other case wonderful dock, however we’ve barely lowered the ranking due to this. Plugable features a two-year guarantee in case you obtain a foul unit.
Belkin Thunderbolt 3 Dock Core – Greatest Thunderbolt dock for journey
Execs
- Compact
- HDMI 2.0 + DisplayPort 1.4 port covers two shows
Cons
- Unlabeled USB-A ports look an identical

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 a virtually 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 supplies 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 Kind 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 strong 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 related to a 60W charger to energy the dock—which isn’t provided. That’s nice in case your laptop computer costs with a USB-C charger; if it doesn’t, you’ll want to purchase one. Meaning further 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
- Stable efficiency
- No thermal issues
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 strong 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. The again additionally homes two DisplayPort 1.4 ports, an HDMI 2.0 port, and a USB-C 3.2 Gen 1 port designed for video. We solely examined this dock with two 4K/60 exterior shows, but it surely’s able to driving three 4K/60 shows offered you will 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 offer extra room, a pleasant contact.
This business-oriented dock consists of vPro assist and the ability button/LED can be utilized to show itself on and off —however solely when related 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 related. We anticipate a firmware improve might remedy these points, and we don’t contemplate them dealbreakers due to the charging capabilities of the opposite ports. When notified of our findings, HP reps mentioned 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 appreciated the construct of the SD5700T, however the value is slightly daunting given the robust competitors.
Do you must purchase a Thunderbolt 4 dock over a Thunderbolt 3 dock? No, not likely. As we clarify in our purchaser’s information beneath, the capabilities of each are largely an identical. However that is the very best Thunderbolt 4 dock we’ve seen, if the spec issues to you.

As well as, the SD5700T supplies gigabit ethernet, a UHS-II SD card reader, and a 3.5mm audio jack. The dock is powered by a fairly highly effective 180W energy provide, amongst the very best we’ve examined. This could present loads of energy (90W) for related units.
We additionally love the lights that present energy and connectivity standing, plus the On/Off button that may relieve pressure in your related laptop computer’s battery.
Plugable 5-in-1 Thunderbolt Hub (USB4-HUB3A) – Greatest Thunderbolt 4 hub
Execs
- Extremely compact
- USB-C to HDMI adapter included
- 15W/60W of charging energy to telephones/PCs
Cons
- Restricted ports
- Greatest for Thunderbolt-attached shows
The Mac world tends to emphasise Thunderbolt-connected shows excess of the Home windows world, so this is likely to be 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’s going to 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 totally take a look at this. However the field does embrace a USB-C to HDMI adapter, so you possibly can 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 nicely. Certain, connecting a second gadget seems like a trouble—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 metallic 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 needed
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 simple 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 toes for positioning the aluminum dock in an horizontal orientation.
Port choice consists of: two Thunderbolt 3 ports (one from the laptop computer, and one for an exterior connection), and a single DisplayPort 1.2 port. That’s supreme 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 Kind 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 nice, although the connection dropped momentarily on each shows when taking part in again video on each shows and transferring recordsdata. In any other case, high-bandwidth video playback went fully easily. The exterior audio jack additionally didn’t work initially, however did on a subsequent retry. CalDigit’s TS3 Plus barely warmed beneath load.
Thunderbolt dock purchaser’s information
In case you’re on the fence about whether or not a Thunderbolt dock is best for you, realizing the solutions to the next questions might make it easier to.
How do I do know if my laptop computer has Thunderbolt?
The quick reply: Take a look at the laptop computer’s printed specs to make certain. A Thunderbolt port could 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 typically don’t need to litter the clear strains of their merchandise by including extra logos, it appears.
Including to the confusion, you might also see USB-C hubs marketed as “Thunderbolt appropriate.” That’s true. You possibly can plug a Thunderbolt dock right into a non-Thunderbolt, generic USB-C port. However it is going to be restricted by the out there bandwidth that the port supplies, 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 knowledge at 10Gbps. Most Thunderbolt 3 ports, the most typical normal, switch knowledge at as much as 40Gbps. Thunderbolt 4 differs barely in that it helps a theoretical most of 32Gbps the place knowledge 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 support page, for instance, particulars its four-lane and two-lane laptops.) Primarily, a 20Gbps connection needs to be sufficient for a single 4K monitor working at 60Hz, with a bit of additional bandwidth for different knowledge transfers amongst related peripherals.
What’s the distinction between Thunderbolt 3, Thunderbolt 4, and USB4?
The quick reply: Not that a lot, and we contemplate 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.
Primarily, 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 advisable docks assist the total specification (and two 4K shows) until famous. Thunderbolt 3 additionally helps a slower (16Gbps) PCIe connection for connecting to exterior storage. Until you’re enhancing video or utilizing an exterior GPU, this in all probability gained’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 knowledge switch — once more, this actually solely issues for video, exterior GPU connections, or presumably 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 essentially 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 gadget will run simply nice plugged right into a Thunderbolt 4 port. However a Thunderbolt 4 gadget could 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 at the very least 15W to energy units plugged into the Thunderbolt port, similar 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, for those who actually need to get into the nice distinctions.
Nearly each Thunderbolt gadget will ship with its personal cable. We’d suggest that you just 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 funds versus full-featured docks we’ve highlighted above. However you additionally may 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 instantly into these hubs. Do you will have an present low-cost USB-C dongle? You possibly can actually plug that in right into a Thunderbolt dock and add much more I/O performance.
Principally, contemplate what you’ll need to plug into the dock as a information for getting one. We favor units with ports inbuilt (similar to HDMI, USB-A, and so forth) because the USB-C gadget ecosystem continues 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 Kind A peripherals do you propose to connect? Do you need to use the Thunderbolt cable to cost your laptop computer, too?
Cables might be an unexpectedly essential consideration, too. Nearly each dock ships with a Thunderbolt cable. However contemplate the shows you personal (sometimes HDMI or DisplayPort) and contemplate 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 doubtless energy it. You’ll want to know how the dock provides energy, although. Verify your laptop computer’s charger to find out how 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 may even see a warning pop up.
A “bus-powered” dock gained’t include an exterior charger within the package deal, saving some value, area, and energy issues. 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 present USB-C charger. (Likelihood is that it gained’t supply the quick-charging capabilities premium smartphones supply, although.) The extra energy your dock provides, the larger the flexibility to cost your laptop computer and any bus-powered units. This can be a gotcha most individuals don’t take into consideration, so for those who plan to attach a number of bus-powered onerous drives or SSDs, purchase a dock with a hefty energy provide. (USB keys, then again, require tiny quantities of energy. Don’t fear about these.)
There’s another consideration: the size of the Thunderbolt cable between your laptop computer and the dock itself. You could have seen or heard about USB-C ports sporting out on smartphones; a unfastened or wobbly connector on Thunderbolt docks could cause displays to unexpectedly flicker or lose connection. Contemplate how a lot pressure will probably 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!
In case you’re a Mac consumer who has stumbled throughout this text, welcome. However please remember 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 lately left unfavourable critiques on Thunderbolt docks on procuring websites due to this. Purchase a PC!
How we examined
We’re working from the premise that you just’re shopping for a Thunderbolt dock for its distinctive potential to hook up with two 4K displays at 60Hz. Decrease resolutions needs to be a lot simpler to run efficiently. Our first take a look at merely related every dock to a pair of 4K/60Hz shows, every of which might settle for DisplayPort and HDMI cabling, and made certain 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 may ship sufficient energy to permit them to function. Right here, we found that one in every of 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 reviews produced by our sister web site, TechAdvisor.co.uk, and authored by Simon Jary.
