Best Thunderbolt 4 and USB4 hubs and docks

Thunderbolt 4 and USB4 hubs and docks are the latest technologies in computer connectivity and expansion. They take over from Thunderbolt 3 and USB-C hubs and docks, with significant future-proof benefits while staying backwards compatible with the older connectivity standards.

Hubs and docks allow you to add more types of connections to your main computer if it lacks them itself – particularly with laptops that might have just a few ports on the side.

Desktop PCs and Macs usually have a decent set of ports at front and back, but laptops and tablets often have just a couple.

You will therefore need to connect a multifunction adapter, hub or a more able docking station that includes the ports and slots you need to add extra devices such as hard drives, memory sticks, storage-card readers, printers and so on, as well as wired input tools such as a keyboard or mouse.

They are also the best way to add an external display or two to your more mobile computer, plus Gigabit (or faster) Ethernet for wired Internet access.

Thunderbolt 4 and USB4

The latest connection standards are Thunderbolt 4 and USB4, which are both based on the neat reversible USB-C connector seen on most new computing devices.

They supersede older USB 3.0/USB-A connectors and also slower USB-C variants in terms of speed, but are backwards compatible with USB-C and Thunderbolt 3.

USB-A (the old rectangular connector that had to go in one way, usually not the first way you tried) usually maxed at a bandwidth of 5Gbps (USB 3.0) but could be as slow as 480MBps (USB 2.0). Many of the models tested here include faster 10GBps USB-A.

USB-C started at 5Gbps but is also available at up to 20Gbps, although 10Gbps is more common at the upper end.

Thunderbolt 3 (TB3) can reach 40Gbps, but, unlike Apple, some Windows PC manufacturers didn’t choose to offer all TB3’s benefits.

Thunderbolt 4 (TB4) and USB4 require manufacturers to comply with all the technology’s benefits (such as 40Gbps bandwidth) to be certified, which makes TB4 much more trustworthy to PC users than TB3.

Apple users won’t see much difference between TB3 and TB4, but there are extra benefits such as the ability to better daisy chain devices. With TB3 a device chain could be disrupted with the removal of any but the final device in the chain.

Many hub and dock manufacturers advise Windows users that their device needs to be certified for Thunderbolt 4 or USB4 due to previous connectivity-standard inconsistency. Mac users will be fine with older USB-C (12in MacBook) and Thunderbolt 3 systems.

You can still use Thunderbolt 3 and USB-C docking stations, but you’ll miss out on Thunderbolt 4’s advancements.

TB4/USB4 also offers faster PCIe (peripheral component interconnect express) at 32Gbps for storage speeds up to 3,000MBps – double the minimum requirements of Thunderbolt 3, although more recent MacBooks have this already. Some of the early TB3 MacBooks had less bandwidth available on the right-hand-side Thunderbolt ports.

After our roundup of the best Thunderbolt 4 hubs and docks, we go into more detail about each type of port or connection that you need.

What is the difference between adapters, hubs and docks?

These terms are used quite fluidly, but there are official definitions.

A hub usually combines multiples of the same type of port – for example, old-school USB-A connections – but often collects a few different ports in a compact form, frequently with a power supply.

A multi-format adapter adds different kinds of ports, usually in a very portable format that can either draw power from the host computer or channel pass-through power delivery via a USB-C port and your USB-C charger.

A docking station (or dock) is a larger beast with its own bulky power supply and a range of different ports that should cover all your connection and charging needs.

The definitions have merged somewhat and are now often more about the size and format rather than the capabilities.

Which ports do you need?

To connect the hub or dock, your computer will need to include either a Thunderbolt 4 port for a separate cable connection (often included with the hub/dock) or an integrated T4/USB4 cable.

Thunderbolt 4 / USB4 ports  The TB4/USB4 technology allows for four of these ports on a hub or dock – one of which is reserved for the computer connection (called the ‘Upstream” connection, compared to the “Downstream TB4 ports that you use to connect new devices). Previously, TB3 allowed for only two in total.

These are very adaptable ports that can connect to a USB-C display or a display adapter – for example, USB-C-to-HDMI or DisplayPort.

Modern SSDs and other devices also have USB-C or Thunderbolt connections, and so you can attach these using the hub when your laptop or tablet has just one or two.

Look out for the charging capabilities of these ports – many can offer 15W power, enough for most smartphones, SSDs etc.

USB-A   This is the old-school, frustratingly non-reversible USB that is common with memory sticks and older devices and chargers. If you still have a few of these hanging around, make sure your hub has one or two to hand. Look for faster USB 3.2 Gen 2 ports that have a decent 10Gbps bandwidth. 5Gbps is fine, but faster is usually appreciated.

If you want to use one for charging, check out the wattage – 7.5W is common and enough to slowly power up a phone. Some USB-A ports are of the older, slower USB-2.0 variety, which can muster a mere 480MBps, and so are mostly used for weedy 2.5W charging rather than data sync, but are also capable of 4.5W or 7.5W charging. If you plan to use these ports for charging, check out the wattages on each hub or dock.

Display ports   Less common on hubs than docks, look out for one or two HDMI or DisplayPorts. You can use the TB4/USB4 ports to connect to a USB-C display or use USB-C (to DisplayPort or HDMI) video adapters if the hub/dock doesn’t include these, but that will use up your spare downstream ports.

Display adapters are inexpensive, costing under £10/$10 each for an unbranded adapter or around £15/$15 for one from Anker. For example, this generic USB-C to HDMI adapter is priced at £8.99/$8.99, while you can buy slightly dearer adapters from Anker or Lention. USB-C-to-DisplayPort adapters are available, such as this generic adapter.

Or you can really splash out with an Apple USB-C Digital AV Multiport Adapter for £75/$69 that comes with a further USB-A port. Belkin has an HDMI adapter priced somewhere in between.

Ethernet   For wired Internet access you need an Ethernet port, at least rated as Gigabit Ethernet (1Gbps). You can also get faster 5Gbps or 10Gbps Ethernet ports as adapters for the TB4 ports.

SD and MicroSD Card Readers   Known mainly for camera cards, these slots also offer affordable access to extra storage, with 500GB cards costing around $60/£60, and capacities up to 1TB. Look for faster UHS-II card readers.

Audio jacks   Headphone and microphone jacks are also handy ports on a hub or dock to save you locating the same on your computer if it even exists.

Some docking stations include higher-quality digital audio connections for serious audio technologies.

Power and charging

Most hubs and docks ship with their own power supply (or “power brick”) to charge the connected laptop or tablet and power the devices attached to it.

Laptops will require a minimum of 60W for charging at a decent rate, but larger laptops need more like 90W. You are more likely to see higher laptop charging on the docking stations rather than the smaller hubs.

The remaining power is shared among the ports, so look for a decent power supply with around 150W total if you plan on using all the ports at the same time.

Hub and dock designs

Think about how and where the dock or hub will sit on your desk. A vertical format will save desk space compared to a slim horizontal one, although most of the hubs we’ve seen are nicely compact.

Also, consider what you want on the front or back of the device. I’m not a fan of hubs that have the upstream computer connection on the front, which can be ugly and inconvenient, although you might prefer it.

None of the hubs or docks we have tested are particularly portable – not because of the size of the hub, but the bulk of the external power supply. Of course, if you buy a second power supply, you could have one at home and one at the office.

Cables

Most of the hubs and docks tested and reviewed here come with at least one short (0.8m) Thunderbolt 4 cable to connect the upstream ports to your computer, but with up to three downstream ports you may well need some more. See our list of the best Thunderbolt 4 and USB4 cables.

Thunderbolt 4 compatibility

Thunderbolt 4 is here and you should consider buying a certified Thunderbolt 4 dock even if you have a Thunderbolt 3 computer because it’s both backwards compatible with older USB-C and Thunderbolt 3 and future-proof – at least until Thunderbolt 5 comes along.

That’s why OWC calls its Thunderbolt 4 docking station just the “Thunderbolt Dock” as it works with TB3 and TB4, although not the distant TB2. If your computer has T2, you need a new computer.

Note, though, that manufacturers of Windows computers didn’t always follow the guidelines for Thunderbolt 3 and so most TB4 hubs and docking stations are not recommended for PC users. They require a properly certified Thunderbolt 4 laptop.

Apple was much better at certification, though, so TB4 hubs and docks will work with all Thunderbolt 3 Macs, which means any from the past few years (2017 and later) are good to go.

Apple’s M1-based 13in MacBooks still have Thunderbolt 3 ports, even though the company calls them “Thunderbolt / USB 4”. If you connect a TB4 dock or hub to an M1 MacBook, you won’t lose any benefits as long as you are using macOS Big Sur or above. But bear in mind that, right now, M1 Macs can connect to only one external display.

The latest 14in and 16in MacBook Pro models – using the M1 Pro or M1 Max chips – do have Thunderbolt 4 ports and can support multiple external displays – they also come with more varied side ports that might even mean you don’t need a hub or a port.
