For an existing card reader, choose a hub with a downstream USB data port that matches the reader’s plug, then decide whether any additional ports earn their space on your desk. Built-in SD or microSD slots can replace a separate reader for those card formats; if you regularly transfer large files, compare the card-reader capability and the entire USB connection rather than relying on a 5Gbps or 10Gbps label alone. Check the computer’s capabilities before counting on a hub’s charging or display functions.
If you already have a USB card reader, an accessible data port may be more useful than built-in card slots or extra display connections. Check where the hub and its cable will sit before adding another device to a crowded desk.
If your cards match the hub’s built-in slots, you may be able to put away your separate reader and free a USB port. Check the exact card formats you use; an SD or microSD slot does not replace a reader for other formats.
If you regularly move large photo or video files, compare the stated USB data rate and whether the card reader supports UHS-I or UHS-II. The card, computer and other parts of the connection also affect the result.
Start with the card reader’s plug and the computer’s available port. Then decide whether integrated card slots or additional transfer and charging capabilities would change how you use the desk.
| Concern | What to check | Who this matters to |
|---|---|---|
| Data access and desk space | Match the reader’s USB-A or USB-C plug to a downstream data port. Check cable direction and clearance around neighbouring ports. | I already have a reader and want to connect it without crowding my desk with unused ports and adapters; around 42% of consumers would put that straightforward connection first. |
| Built-in card slots | Check that the slots accept your SD or microSD cards and whether the stated reader capability suits your use. | If the hub takes my cards directly, I can remove a separate reader and free its USB port. For around 33% of consumers, replacing that reader would be the main priority. |
| Transfers and charging | Compare the USB data rating with the card and reader capabilities. If you need laptop charging, check the host, charger and hub’s pass-through requirements. | Regularly moving larger files or sharing the hub with other desk devices makes connection capability more important to me; around 25% of consumers would prioritise transfer or power needs. |
A USB-C Power Delivery input can be reserved for a wall charger rather than peripherals. Anker Support specifies that the PD-input port on its A83D2 hub cannot power peripheral devices.
Check the port diagram for a downstream USB data port that matches your existing reader.
Built-in SD and microSD slots help only when they accept the cards you use. A reader for another format may still need its own USB connection.
List your card formats and reader plug before deciding between integrated slots and an external-reader setup.
The USB Implementers Forum identifies these as interface performance levels, not guaranteed file-copy results. The card, reader, computer port, cable and destination storage can also limit a transfer.
If large transfers are a regular task, compare the capabilities of the complete connection, including UHS-II support where relevant.
A matching connector does not establish that the computer supports the hub’s intended video output or charging arrangement.
Check the computer’s specifications for the USB data, Power Delivery and display capabilities you intend to use.
Anker’s compact USB-C multiport hubs include models that combine USB data connections with SD and microSD slots.
CalDigit’s SOHO Dock is a compact dock to examine when UHS-II card reading and additional desktop connections matter.
UGREEN’s multiport hubs offer combinations of USB data ports, SD/TF slots and other desk connections, depending on the model.
These hubs cover several ways to connect an external reader, including a USB-A-host option and USB-C multiport models with built-in SD/TF slots. Match the reader and computer connections first; choose extra slots, display ports or charging only if you will use them.

Consider this USB-C dock if you want a data connection for an external reader as well as built-in SD/TF slots.
Its product name specifies USB-C 10Gbps and USB-A 10Gbps/5Gbps connections, SD/TF slots rated at 160 MB/s, 4K 60Hz HDMI and 3.5 mm audio. Check the reader plug, host capabilities and desk clearance; the stated rates do not guarantee file-copy speed.

This USB-A-host hub is an option if your computer has a USB-A port and your existing reader connects through USB-A.
The product name specifies three USB 3.0 ports, an RJ45 LAN connection and a 0.2 m cable. Check the host and reader plugs before choosing it; it is not a built-in card reader.

Consider this adapter for an external USB-A card reader if you also need its display or network connections.
Its product name lists two USB 3.0 ports, 4K HDMI, VGA, Gigabit Ethernet and 100W Power Delivery. Check desk clearance and confirm the computer supports the display and charging functions you intend to use.

This USB-C hub offers both USB data ports for an external reader and SD/TF slots if you want to connect cards directly.
Its product name specifies one 10Gbps USB-A port, one 10Gbps USB-C port, two 480Mbps USB-A ports, dual HDMI outputs, RJ45 and a USB-C PD port. Choose the data port that matches your reader, and check desk clearance and host display support if you intend to use HDMI.

This USB-C converter is worth considering if you need a connection for an external USB-A reader or want built-in SD/TF slots.
The product name lists USB 3.0 and USB 2.0 connections, SD/TF slots, HDMI and PD. Check which port matches your reader, whether the computer supports the functions you need and whether the converter fits your desk.
No: the port must support downstream USB data and match the reader’s connector. Anker Support specifies that the PD-input port on its A83D2 hub is for an external wall charger and cannot power peripherals, so check each hub’s port labels rather than relying on the USB-C shape.
Built-in slots can replace it when they accept your SD or microSD cards and meet the reader capability you need. Keep a compatible external reader for other card formats, and compare UHS-I or UHS-II specifications if transfers are an important part of your work.
Not necessarily. The USB Implementers Forum identifies 5Gbps and 10Gbps as interface performance levels; copy speed also depends on the card, reader, computer port, cable, destination storage and devices sharing the hub.
Do not count on a port labelled PD input for the reader: it may be reserved for a charger. Check the hub’s port diagram for a separate data port, and, if laptop charging matters, confirm the required charger and the power the hub can pass through.
