Best Thunderbolt 4 Hubs & Docking Stations Windows Central 2021
The best Thunderbolt 4 hubs and docking stations are slowly taking over for the best Thunderbolt 3 docks thanks to much better performance and compatibility with many other interfaces. Even if you have a PC with Thunderbolt 3, USB4, or USB-C, many of these docks will provide extra ports. Thunderbolt 4 is still emerging, so hardware is limited. Let's take a look at some of the best Thunderbolt 4 hubs and docks out there.
- Best Overall: CalDigit Element Hub
- Also Great: Kensington SD5700T
- Good Value: OWC Thunderbolt Dock
- Best Style: Razer Thunderbolt 4 Dock Chroma
Best Overall: CalDigit Element Hub
The CalDigit Element hub is made by the same company that makes the formidable CalDigit TS3 Plus Thunderbolt 3 dock, our pick for the overall best laptop docking station. The Element hub is sized smaller and priced lower than some of the other Thunderbolt 4 options, making it a good choice if you lack space on your desktop. It does require a substantial AC adapter, so don't expect to take it with you on the road without quite a bit of bulk.
The host laptop plugs into the side of the dock and opens up seven extra ports. The front edge is four USB-A 3.2 (Gen 2) with 10Gbps speeds and 7.5W of charging power. The back edge holds the AC input and three Thunderbolt 4 ports with 40Gbps speeds and 15W of charging power. While connected, note that the host laptop will receive up to 60W charging power when needed.
You can daisy-chain the Element hub with a larger dock (like the TS3 Plus) for even more ports, and the reversible design gives you extra options for desk setup. As for monitor support, the Element hub handles up to dual 4K displays at 60Hz in both extended or mirror modes, single 8K display at 30Hz, or 5K Thunderbolt display at 60Hz. And if you're connecting high-speed external storage, expect read speeds up to 3,000MB/s.
As long as you're not searching for a wide variety of ports and want to add USB-A and Thunderbolt 4, this is a great dock that isn't as expensive as many of the other options. The Element hub is currently sold out everywhere, but another shipment is expected to go out in May 2021. You can preorder one from CalDigit in the meantime.
- Adds four USB-A 3.2 (Gen 2)
- Adds three Thunderbolt 4
- Durable aluminum design
- More affordable price
- Compact size
- No Ethernet
- No SD card readers
- Sizeable AC adapter makes it hard to travel with
Also Great: Kensington SD5700T
Kensington is another leading company in the world of hubs and docking stations. Its SD5700T Thunderbolt 4 dock is a great choice if you're looking for a permanent solution and have ample space on your desk. It's a bit larger than the Element hub, but it adds a better mix of ports. If you need Ethernet, a UHS-II SD card reader, or a 3.5mm audio jack, this dock is no doubt going to make a great choice.
It connects to the host with Thunderbolt 4 and adds 10 ports, including one USB-A 2.0, three USB-A 3.2 (Gen 2), and three downstream Thunderbolt 4. You can get up to 90W charging power back to the laptop (great for PCs with dedicated GPUs that require more power), and there's support for a single 8K display at 30Hz or dual 4K displays at 60Hz.
For some extra security, the dock includes a Kensington lock slot and a Kensington Nano lock slot. And if you don't want to keep the aluminum dock on your desk, there are mounting solutions available. The SD5700T is currently available to buy.
- Three-year warranty
- Up to 90W host charging power
- SD card reader and Ethernet included
- Three downstream TB4 ports
- Can be mounted
- Costs more
- Takes up more desk space
Good Value: OWC Thunderbolt Dock
OWC's Thunderbolt dock is in many ways almost identical to Kensington's SD5700T, right down to port selection, port layout, and lock slots. A big difference, however, is the price. The OWC version costs about $249, while the SD5700T costs around $330. Why the price discrepancy? OWC's dock has a lot more plastic and a shorter two-year warranty. If those things don't matter, you're going to get the same connectivity for a lot less money.
The dock connects to the host laptop with Thunderbolt 4 and provides up to 90W charging power. There's a USB-A 2.0 port on the front, flanked by a UHS-II SD card reader and 3.5mm audio jack. The back edge has three downstream Thunderbolt 4, Ethernet, three USB-A 3.2 (Gen 2), and the AC hookup. It will handle dual 4K displays at a 60Hz refresh rate or a single 8K display at 30Hz.
A Kensington lock slot and Kensington Nano lock slot are included on the side. The first production run of this dock sold out fast, but there are more docks on the way in April 2021. You can preorder now from the OWC website.
- Cheaper than other options
- Great port variety
- Up to 90W host charging
- Lock slots included
- Shorter two-year warranty
- More plastic
Best Style: Razer Thunderbolt 4 Dock Chroma
Razer seems to have a version of just about any peripheral you can think of, including a Thunderbolt 4 dock. And true to Razer's vision, it's a high-performance option that's soaked with RGB. Yes, even your docking station can have a sweet Chroma underglow to make your office look that much cooler.
The dock follows nearly the same port setup as the other full-size docks in this collection, though it drops the wimpy USB-A 2.0 port on the front. Connecting with Thunderbolt 4, you get access to three downstream Thunderbolt 4 ports, 3.5mm audio jack, a UHS-II SD card reader, three USB-A 3.2 (Gen 2), and up to 90W charging power to the host.
Razer's Chroma RGB syncs up with your other compatible accessories and offers 16.8 million colors for you to mess around with. Note that the dock has a relatively short one-year warranty. The dock is currently out of stock everywhere, but you can sign up for notifications at Razer's website.
- Fancy RGB underglow lighting
- Three downstream Thunderbolt 4
- Black finish might be better suited to some desks
- Dual 4K@60Hz display support
- One fewer USB-A port than other picks
- One-year warranty
The best Thunderbolt 4 hubs and docks all provide robust external monitor support, lots of USB-A connectivity, and charging back to a host laptop. If you need an SD card reader or an Ethernet port, the full-size docks are no doubt going to be a better choice. You can get the well-built Kensington SD5700T, the cheaper OWC Thunderbolt dock, or the RGB-infused Razer Chroma.
But if you don't want to go with a full-size option and instead need to add USB-A ports and downstream Thunderbolt 4, the compact CalDigit Element hub is your best choice. It costs less than the other options, it still supports external monitors, and you can daisy-chain with other docks if you need even more connectivity.
If Thunderbolt 4 isn't really what you're looking for, be sure to check out our collection of the best Thunderbolt 3 docks for more buying options.
