Card-reader users short of USB ports
If your reader connects by USB, count the data ports left for a mouse, keyboard or storage device after plugging it in. That matters more than the hub’s total number of connectors.
Who needs which connections?
USB-C laptop users who must keep charging
When the USB-C port needed for the hub normally charges your laptop, look for Power Delivery pass-through and check the power available to the laptop after the hub takes its share.
Fixed-desk users with several accessories
A multiport adapter becomes relevant when the reader must share the desk connection with a monitor, wired network or several peripherals. Those additional functions still depend on the laptop’s host-port capabilities.
What should you check?
Establish whether you need built-in SD or microSD slots or a data port for a separate reader. Then check charging and any other desk connections you intend to use.
| Concern | Buying checks | Who this matters to |
|---|---|---|
| Usable data ports | Match the reader’s USB plug and the computer’s host connector; count the data ports remaining for essential accessories. | I need my USB reader connected alongside everyday peripherals without swapping cables. Around 36% of consumers put correctly matched data ports first. |
| Laptop charging | Check host charging support, the laptop’s power requirement and how much of the hub’s Power Delivery input reaches the laptop; check whether a charger is included. | If the hub occupies the port I use to charge my laptop, I need both connections working together. Around 29% of consumers make charging continuity their primary concern. |
| Card access and transfer speed | Check the reader’s interface and the relevant hub data port, or the stated card formats and standard for built-in slots. | For frequent card transfers, I care whether the connection suits my reader or SD media rather than gaining display ports. Around 21% of consumers prioritise card access and transfer capability. |
| Compact setup | Check the hub’s dimensions, host-cable length and plug spacing, as well as whether it needs a separate power connection. | When I move between desks, I want the reader and essential accessories connected without a cumbersome adapter. Around 14% of consumers put a compact setup first. |
Common buying mistakes
-
Counting USB-C shapes instead of data ports
A USB-C connector used for Power Delivery is not necessarily an available peripheral data port. The reader may therefore have nowhere suitable to connect.
Match every device plug to a port explicitly described as supporting data, and confirm that the computer’s USB-C host port supports USB data.
-
Assuming pass-through charging replaces a charger
Power Delivery pass-through uses power from a charger, and the hub may reserve some of that power for itself. A headline input rating is not necessarily the power reaching the laptop.
Compare the laptop’s charging requirement with the hub’s stated output to the laptop, and check what comes in the box.
You may need to provide a separate compatible USB-C charger.
-
Choosing display connections for a reader-only setup
HDMI, Ethernet and other dock connections add functions but do not resolve a mismatch between the card reader’s plug and the hub’s data ports.
Start with the reader and essential peripherals; consider a multiport desk adapter when you also need its display or wired-network connections.
-
Confusing an SD slot with a separate card reader
Built-in SD and microSD slots serve the stated media formats. They do not establish compatibility with a specialist USB reader or payment-card device.
Identify the reader’s plug, power and software requirements before deciding whether built-in slots or a separate USB data port meet your needs.
Relevant brands to consider
Anker
Anker’s 341 is a portable USB-C multiport hub combining USB data connections with SD and microSD slots, HDMI and charging pass-through.
- Anker UK specifies two USB-A data ports and one USB-C data port on the 341, alongside the card slots.
- Anker UK states that up to 15W of its 100W Power Delivery input is reserved for hub operation and that a charger is not included. Check which functions your laptop’s USB-C port supports.
Belkin
Belkin describes its AVC009 as a slim USB-C multiport adapter for moving between workstations or reducing desk clutter.
- Its compact format is worth considering if carrying an adapter between desks matters to you.
- Check the AVC009’s available data connections against your particular card reader and computer before choosing it.
StarTech.com
StarTech.com offers both a data-focused USB-C hub with card slots and a multiport adapter for a desk with additional connections.
- StarTech.com specifies three USB-A ports and a UHS-II SD/microSD reader for the bus-powered HB31C3ASDMB.
- Its DKT30CHVSCPD adds display, Ethernet and charging pass-through; those functions need a reason in your desk setup and do not make it necessary for a reader-only connection.
Joybuy product choices
These USB-C adapters offer different combinations of USB data connections, card slots and desk connections. For a separate card reader, match its plug to a data port; built-in SD or microSD slots are relevant only if you use those card formats.

The product name lists a 10Gbps USB-A port, a 10Gbps USB-C port, two 480Mbps USB-A ports, SD/TF, RJ45 and two HDMI connections. Check that the computer supports the functions you plan to use and how much charging power reaches the laptop through the PD connection.

Frequently asked questions
Will any USB-C hub work with my card reader?
No: the reader needs a matching hub data port, and the computer’s USB-C host port must support USB data. If you also need charging or video, check those host functions separately rather than relying on the connector shape.
Do I need a powered hub for one card reader?
Not necessarily; a bus-powered data hub can suit a reader and low-power accessories when their connection and power requirements match. StarTech.com describes its HB31C3ASDMB as bus-powered. Consider Power Delivery pass-through if you also need to charge the laptop through the occupied USB-C port.
Will a 100W pass-through hub charge my laptop at 100W?
Not automatically: 100W may describe the hub’s maximum Power Delivery input rather than its output to the laptop. Anker UK and StarTech.com each specify models that reserve 15W for hub or dock operation, leaving up to 85W for the laptop with a compatible charger. Check the figures for the exact model you choose.
Does a UKCA or CE mark confirm that a hub will work with my reader?
No. Department for Business and Trade guidance on products placed on the Great Britain market says those markings indicate that the manufacturer believes the product meets relevant requirements; they do not establish compatibility with a particular reader or computer. Check the reader’s connector and the host and hub functions separately.
