Pen-tablet users short of USB-A ports
If your non-display tablet uses a USB data connection, a hub can make room for the tablet and other desk accessories. It will not add a video connection.
Who needs which connection?
Pen-display users building a laptop workstation
Your display tablet may need video, USB data and power through separate connections. Follow its documented cable arrangement before deciding which laptop ports a hub must provide.
USB-C setup checkers
Matching USB-C sockets do not establish a working connection. Check the tablet’s approved cable and whether the computer port supports the data, video and power functions that tablet requires.
What should you check before buying?
Start with the tablet maker’s connection diagram. Once its data, video and power paths are clear, choose the ports and power arrangement your desk needs.
| Concern | What to check | Who this matters to |
|---|---|---|
| Connection path | Check whether the exact tablet needs USB data alone, HDMI plus USB and power, or a supported one-cable USB-C display connection. | If my pen display needs a video signal, extra USB data ports alone will not connect it; around 36% of consumers put the connection path first. |
| Shared power | Check the hub’s external adapter and its stated power limits against the devices you intend to connect. | When my tablet shares a hub with several accessories, I want to avoid interruptions caused by limited available USB power; roughly 29% of consumers prioritise power stability. |
| Port and cable compatibility | Confirm the approved tablet cable and the computer port’s required data or display capability. | A USB-C socket on each device does not tell me whether my intended cable route works; about 21% of consumers put port and cable compatibility first. |
| Desk connections | Count the USB data ports you need and decide whether HDMI, card readers or laptop charging pass-through serve your setup. | Once my tablet’s essential connections are covered, I want enough ports for my other desk devices; around 14% of consumers prioritise expansion. |
Connection mistakes to avoid
-
Buying a data-only hub for a pen display
A USB data hub cannot supply a display signal merely by adding ports. Wacom and XPPen document pen-display connection routes that also require video and, depending on the route, a power connection.
Check the exact tablet’s connection diagram before buying a hub, video adapter or dock.
The documented route may require a separate video connection or power supply.

Assuming all USB-C connections do the same job
Huion identifies graphics tablets with USB-C sockets that do not support a USB-C-to-USB-C connection. A supported one-cable pen display can have further requirements for the computer’s video output.
Match the tablet maker’s specified cable to the computer port’s data and display capabilities.
-
Sharing too little power across devices
StarTech.com explains that an unpowered hub shares the power available from its computer connection. Devices with greater combined demand may not operate reliably.
For a tablet and several accessories, compare their requirements with the hub maker’s limits and use its specified external adapter where needed.
-
Overlooking the powered hub’s mains connection
A powered hub adds an adapter and another connection to the desk. Electrical Safety First warns against daisy-chaining extension leads because of overheating and fire risk.
Use the adapter specified for the hub, avoid daisy-chained extension leads and stop using equipment that shows damage or unusual heating.
Relevant brands to consider
TP-Link
The UH700 is a USB-A expansion option for a non-display pen tablet and other USB-A desk devices.
- TP-Link lists seven USB 3.0 Type-A ports, transfer speeds up to 5Gbps and a supplied power adapter for the UH700.
- It does not provide the HDMI or full-featured USB-C display path a pen display may require. Check the power limits for the hardware version and connected devices.
Anker
The Anker 341 combines USB data ports with HDMI, card readers and laptop charging pass-through for a compatible USB-C workstation.
- Anker lists two USB-A data ports, one USB-C data port, HDMI, SD and microSD slots, and a USB-C Power Delivery input.
- Anker states that a charger is not included. Its HDMI socket alone does not establish compatibility with a particular pen display.
StarTech.com
The ST73007UA is a USB-A expansion hub with the option of using external power.
- StarTech.com lists seven USB-A ports, bus- or self-powered operation and an included 20W adapter.
- When used without external power, connected devices share the power available from the computer port. It is not a video-output dock.
Joybuy products for USB-C workstations
These USB-C adapters and docks offer USB data alongside display connections for laptop workstations. Their ports are starting points for checking a pen display’s documented connection route, not confirmation that a particular tablet will work.

Frequently asked questions
Will any USB hub connect a graphics tablet?
No: the required connection depends on the tablet. A non-display pen tablet may need USB data alone, while Wacom and XPPen document pen-display routes that also require video and, in some arrangements, separate power. Follow the instructions for your exact model.
When should I choose a powered USB hub?
Consider a powered hub when several devices share the connection or their combined power needs may exceed what the computer port can supply. StarTech.com explains that an unpowered hub shares the host port’s available power; check the hub’s limits and use its specified adapter.
Does a USB-C socket mean a USB-C-to-USB-C tablet cable will work?
No. Huion identifies models, including the HS611 and H1161, that do not support that cable route despite having USB-C sockets. For a supported one-cable pen display, also check the computer’s required video and power capabilities.
Can a USB-C hub’s HDMI port connect a pen display?
It can be part of the connection if the tablet maker documents an HDMI-based route and the computer can provide the required video output. Check the tablet’s USB data and power connections as well; an HDMI socket on its own does not establish compatibility.
What should I check when using a mains-powered hub?
Use the adapter specified for the hub and avoid daisy-chaining extension leads, which Electrical Safety First warns can cause overheating and fire. For equipment placed on the Great Britain market, the Office for Product Safety and Standards publishes guidance on the Electrical Equipment (Safety) Regulations 2016; that Great Britain guidance is not a determination of Northern Ireland requirements.
