Who each setup suits

Single-drive laptop users

If a wall socket is already occupied, you may want to attach an external SSD or portable hard drive while continuing to use your laptop charger through a USB-C hub.

Backup and media-transfer users

If you regularly copy photos, video or backups, the data rate of the port used by the drive matters more than the USB-C connector shape alone.

Fixed-desk users with several peripherals

If a drive stays connected alongside a monitor, network connection, keyboard or mouse, count the ports you need and check the dock’s power and laptop compatibility.

What to check before buying

Start with the power arrangement: a pass-through hub can use your laptop charger, while a mains-powered dock needs its own socket. Then check the particular ports, drive, laptop and cable that will make up your setup.

Concern What to check Who this matters to
Using fewer sockets Check pass-through charging and the power the hub reserves for itself. If considering a powered dock, account for its mains connection. With limited sockets, I want my laptop charger to serve the laptop and hub without plugging in another adapter. Around 30% of consumers put socket consolidation first.
Drive transfer speed Match the drive’s interface and cable to the stated data rate of the port it will use; do not judge speed by connector shape. When I copy large photo, video or backup files, I want to avoid choosing a port that limits a compatible drive. Transfer speed is the primary concern for around 30% of consumers.
Laptop compatibility Confirm the host port’s USB-C, USB4 or Thunderbolt functions and whether it supports the charging or display connections you need. Before committing to a dock, I need to know that my laptop and cable can use the functions I plan to connect. Around 20% of consumers put compatibility first.
Desk expansion Count usable drive, display, network and input-device ports separately, including any ports reserved for charging. I want my drive and other desk peripherals to stay connected instead of swapping cables whenever I work. Keeping those connections available comes first for around 20% of consumers.

Common buying mistakes

  • Counting a charging input as a drive port

    On the Anker 565 USB-C Hub, the USB-C Power Delivery input is for charging, not data. Counting every USB-C connector as a storage connection can leave you short of a usable drive port.

    Check each port’s stated function and reserve a confirmed data port for the external drive.

  • Equating charger input with laptop charging power

    A pass-through hub can use some incoming power itself. Anker UK specifies up to 100W pass-through input for its 555 USB-C Hub, minus 15W for hub operation; Dell UK lists different host-charging figures for Dell and non-Dell systems on the WD25TB4.

    Compare the power stated as delivered to your laptop with its charging requirement, rather than relying on the charger’s rating alone.

  • Choosing a cable by its USB-C plug alone

    The USB Implementers Forum notes that cables do not all have the same capabilities. A cable that physically fits does not establish the data rate or power capability needed for your drive and laptop.

    Use the dock-supplied cable where appropriate, or check a replacement cable’s data and power ratings against the intended connections.

Relevant brands to consider

Anker

Its compact USB-C hubs are relevant when an external drive and laptop charging need to share one laptop connection.

  • Anker UK specifies Power Delivery pass-through on the 555 hub and 10Gbps USB-C and USB-A data ports on the 565.
  • On the 565, the Power Delivery input is charging-only; count its data ports separately when planning drive connections.

CalDigit

The Element Hub is a Thunderbolt 4/USB4 option for a compatible laptop at a fixed desk.

  • CalDigit specifies four 40Gb/s Thunderbolt 4/USB4 ports and four 10Gb/s USB-A ports for the Element Hub.
  • CalDigit notes that some PCs limit Thunderbolt functions and some Apple M1/M2 models have external-display restrictions; check the exact laptop.

Dell

The WD25TB4 is a mains-powered dock to consider when a drive and several desk peripherals need to stay connected.

  • Dell UK lists 10Gbps USB-A and USB-C ports and downstream Thunderbolt ports for the WD25TB4.
  • Dell UK specifies 130W host Power Delivery for Dell systems but 96W for non-Dell systems; use the figure applicable to your laptop.

Frequently asked questions

Can a USB-C hub charge my laptop while an external drive is connected?

Yes, if the hub supports Power Delivery pass-through and has a separate data port for the drive. Check the power delivered to the laptop after the hub’s own use; Anker UK states that its 555 USB-C Hub accepts up to 100W pass-through input minus 15W for operation.

Will any USB-C port work for a fast external SSD?

Not necessarily: the port’s data capability, the drive and the cable all matter. The USB Implementers Forum notes that cables have different capabilities, so check the stated data ratings throughout the connection rather than relying on the USB-C shape.

Do I need Thunderbolt to connect an external drive?

No; a USB-C hub with a suitable data port can serve a single drive. Consider a Thunderbolt 4 or USB4 hub when you need its additional high-bandwidth connections and your laptop and cable support them; Microsoft advises checking the PC’s USB4 support for USB4 devices and docks.

What should I check on a powered dock for use in Great Britain?

Check the dock and its mains adapter for clear product identification, instructions and the conformity marking applicable to that equipment. GOV.UK guidance says that certain goods meeting EU requirements, including CE marking, continue to be recognised in Great Britain; check the requirements for the particular product rather than treating a plug shape or marking alone as proof of suitability. Northern Ireland has different arrangements.
