Compatibility guide based on manufacturer documentation. No hubs were tested for this article.

A hub can tidy up your desk and give you room for a mouse, storage drive and monitor. Our buying advice is to start with your laptop model and a list of what you want to connect.

1. Check the laptop port

USB-C describes a connector; the features behind it vary. For a conventional USB-C HDMI hub, confirm DisplayPort Alt Mode support. Charging through a hub also requires compatible laptop charging support. Microsoft recommends matching the computer, accessory and cable capabilities.

2. Write down your screen requirements

Tell the seller your monitor model, resolution, refresh rate and whether you want one or two external screens. Ask for written confirmation of the intended arrangement. A listing that says “4K” leaves several useful questions unanswered.

3. Check power reaching the laptop

A hub’s input power rating may exceed what it passes to the computer. As a concrete example, Anker specifies up to 100 W input and approximately 85 W to the laptop for its 555 hub. Use the exact model’s output rating when comparing it with your laptop’s requirements. Check whether a charger is included.

4. Pay for the ports you will use

Your setup	What to put on your shopping checklist
Mouse and keyboard	Enough USB ports of the correct type
Desk monitor	Confirmed display compatibility and required resolution/refresh rate
Regular file transfers	Suitable data-port speed and compatible cable
Wired office network	Ethernet port and the required network speed
Camera workflow	Card reader matching your memory cards

5. Compare the complete cost

Include any charger, display cable or adapter you still need. A cheaper hub can become an expensive purchase if it leaves one essential task unsolved.

CY Global Tech verdict: choose the smallest setup that meets your actual requirements, with compatibility confirmed for your exact laptop. A useful pre-purchase message is: “My laptop is [model], my monitor is [model], and I need [devices] connected together.”
