Modern laptops trade ports for thinness. A good USB-C hub brings HDMI, USB-A, and charging back — a bad one overheats and drops displays.
Pick Ports You Will Use
| Port | Why you might need it |
|---|---|
| HDMI | Class projector / monitor |
| USB-A | Flash drives, mouse receivers |
| USB-C data | External SSD |
| PD pass-through | Charge laptop while hub is plugged in |
| SD reader | Cameras / some creators |
| Ethernet | Stable fibre when Wi‑Fi is weak |
Don’t pay for seven ports you’ll never use.

Red Flags

- Claims 8K HDMI on mystery hubs

FAQ
Hub vs dock?
Docks are heavier/pricier with more ports and sometimes dual monitor support — overkill for most students.
Will any hub charge my laptop?
Only with proper PD negotiation and a strong enough charger.
