USB‑C Hubs Under $40: What Ports Do You Actually Need?

Overview

The right USB‑C hub under $40 depends on your laptop’s capabilities and the ports you actually use. Avoid paying for features you won’t use, and make sure HDMI bandwidth matches your display.

Port Checklist

  • HDMI: Prefer 4K30 minimum; if you need 4K60, verify your laptop supports DP Alt‑Mode with enough lanes.
  • USB‑A: Two or more ports for keyboard, mouse, and flash drives.
  • SD/microSD: Handy for creators and photographers.
  • Power pass‑through: If your laptop has one USB‑C port, pass‑through charging is crucial.
  • Ethernet: Adds reliability for streaming and large downloads.

Display Notes

  • Mirroring vs extended: macOS on Intel once had limitations—modern Macs/PCs are fine for extended displays with the right adapter.
  • Cable quality: Use a certified USB‑C cable; cheap HDMI cables cause flicker or no signal.

Troubleshooting

  • Display not detected: Re‑seat cables, try a different HDMI port, and update GPU drivers.
  • Power issues: Verify hub wattage and your charger’s output; gaming laptops may require the original brick.
  • Hot devices: Hubs can run warm—don’t block vents.
