BENFEI USB C to HDMI Adapter 4K@60Hz Thunderbolt 3 to HDMI

BENFEI USB C to HDMI Adapter 4K@60Hz Thunderbolt 3 to HDMI
Pros:
Cons:
Specification:
Input Interface USB-C
Video Output Resolution Up to 4K at 60Hz (HDMI output)
Compatibility (Devices) Samsung Galaxy S8/S9/S8 Plus/S9 Plus/Note 8; Mate 10; HTC U11; also compatible with USB-C computers/desktops for multi-monitor HDMI output
Cable Build & Housing Braided nylon cable; premium aluminum alloy housing
Warranty & Support 18-month warranty with responsive customer service

You pull this BENFEI dongle from the package and immediately notice the braided cord and the sturdy aluminum shell. It feels purpose-built for quick setups, unlike the flimsy adapters I’ve tugged out of drawer clutter before.

The first plug-in into a USB‑C port and the HDMI end seating neatly into a TV is a small win right off the bat.

In use, it streams 4K at 60Hz smoothly on my Samsung Galaxy S8 and S9 setups, which is surprisingly reliable for something that’s marketed as a computer-focused adapter with limited charging. The plug-and-play nature means no drivers, no fuss—just plug, select the HDMI input, and you’re watching.

It’s a reassuring, simple experience when you’re scrambling to get a presentation ready or when you want to mirror photos from a trip without Wi‑Fi hiccups.

The design feels thoughtful for travel with a compact footprint, and the non-slip grip on the housing helps you unplug without tugging at the cable. I appreciated that the cable length isn’t excessive, so you aren’t wrestling a long cord around a hotel desk.

It’s one of those small devices that disappears into your workflow until you actually need it.

Where it shines is compatibility with a broad range of devices—especially the Galaxy line. It also felt solid when driven from a MacBook Pro or Pixelbook, letting you drive one or two HDMI displays at 4K without a charger port attached to the adapter itself.

The trade-off: it’s designed for computers first, so tablets and phones beyond the Galaxy line aren’t guaranteed to perform the same way.

Overall, if you want a dependable, no-drama USB‑C to HDMI solution for travel, meetings, or movie nights without worrying about Wi‑Fi, this feels like one of the better options you can actually reach for. It’s not flashy, but it gets the job done with consistency you’ll notice in real use.
