Top Connectivity Ports You Actually Need: USB-C, Ethernet, HDMI (and What to Skip)

If you bounce between coworking desks and hotels, the right ports can mean stable calls, fast uploads, and a clean setup. Here’s what to prioritize—plus what’s usually a waste of weight.

In this article, we organize USB-C, Ethernet, and HDMI in order of the “most likely to be used,” and remove the connections you’re least likely to need to bring along. It’s a way of thinking to keep things running reliably with the same “lightweight set,” from business trips within Japan to travel abroad.

USB-C (Top priority): charging and “coordinator”

On most job sites, USB-C can handle “power,” “data,” and even “some video.” When choosing a smart hub, first check whether the USB-C ports offer enough functionality.

  • Power Delivery (PD) supported:You can consolidate on-site charging into a single connection.
  • High-speed data:You'll enjoy smoother sharing of photos and documents, as well as external SSD operation.
  • Plenty ofport capacity: it’s important if simultaneous connections are a requirement.

Ethernet (runner-up): Get back up and running instantly in areas with weak Wi‑Fi

In Tokyo’s hotels and coworking spaces, Wi‑Fi can become congested, which may slow down your connection. Having Ethernet helps you keep your work rhythm from getting disrupted.

Checkpoint: The more frequently people who need LAN connections (more meetings, heavy uploads, remote monitoring), the higher the value of Ethernet.

HDMI (purpose-specific): Switch the display to “work mode”

HDMI is a connection that works only when you need it. There may be days when everything can be done with just a notebook PC, but if you have presentations, dual-screen work, or shared monitor operations, having it on hand is a big advantage.

  • Projecting and displaying is required in meeting rooms and shared spaces, including projection and display.
  • Dual display to improve work efficiency.

“Skip candidate” approach: operational probability over multifunctionality

Lightening starts by removing the “extra” features you want. To avoid mistakes, use “how many times you’ll use it per year” as your benchmark like this.

  1. Last used date (reduce priority for items that weren’t used recently).
  2. Check whether there is an alternative (cloud sharing, Wi‑Fi, a different adapter, etc.).
  3. Calculate the “sense of security” for the distance traveled (leave those with the highest priority based on real-world experience).

As a result, the configuration that uses USB-C and Ethernet to ensure “daily stability” and uses HDMI to create a “work mode for the situations that require it” is the most versatile.

When in doubt, go with this conclusion

USB-C:Charge and basic connectivity in one.

Ethernet:Use a “buffer” to smooth out Wi‑Fi signal fluctuations.

HDMI: Works for meetings and a two-screen setup.
