Transform your USB-C port into a powerful hub with Monoprice USB-C Multiport Adapters!
From smartphones to laptops, we rely on these gadgets for work and leisure. However, as devices become more advanced, they often require different ports and connections to function properly. This is where a multiport adapter comes in handy.
A multiport adapter is a small device that allows you to connect multiple peripherals or devices to your computer or laptop simultaneously. It serves as a bridge between your computer and other devices such as external hard drives, monitors, keyboards, mice, and more. A single port on a laptop may not be enough for all the necessary connections needed for work or entertainment purposes. Monoprice has a couple of great options for multiport adapters — the 7‑in‑1 USB‑C Multiport 4K HDMI Adapter and the 6‑in‑1 USB‑C Multiport 4K HDMI Adapter.

One of the key features of this adapter is its ability to support up to 4K resolution video output through its HDMI port.

User Experience
The 6-in-1 and 7-in-1 Multiport Adapters come in simple boxes that only feature the Monoprice branding on them. The back of the boxes have a few design callouts but for the most part, the packaging is bare. I want to point out that the part number is listed just above the barcode. Since the names of these products are fairly ambiguous I found the P/N to be invaluable because I was able to easily track them down on Monoprice’s website.
One of the first observations I made was that each of these adapters offers the same benefits to users. The 7-in-1 adapter includes an Ethernet port whereas the 6-in-1 does not. Because of this one design difference, the 7-in-1 adapter is slightly longer than the 6-in-1 adapter. Both adapters keep all the ports to one side with on port on the end and the USB-C extension cable on the opposite end.

Getting started with the adapters was easy. There is no special software needed to use them. You simply plug them in and connect the needed devices to the adapters so that your computer can communicate with them. Both adapters seamlessly connected to my laptop without any issues, and the plug-and-play functionality worked flawlessly. I appreciated that I didn’t have to install additional drivers or software to get it up and running.
The adapters are compact and have a sleek, modern design. I was quite impressed with their performance and versatility. Because of their size and form, I was able to easily slide them into my computer bag and visit remote workspaces without having to worry about whether or not I would be able to connect to my various peripherals. The adapters offer a range of connectivity options that make it an excellent companion for USB-C devices.
While I was in my home office, I did connect my laptop to a 4K display and was impressed with the connection between the two devices. The adapter delivered crystal-clear visuals with vibrant colors and smooth motion. Whether I was watching movies, editing photos, or working on design projects, the adapter provided an immersive and visually stunning experience.
The build quality of the Monoprice 7-in-1 adapter is impressive. It feels solid and durable, and the white coating on the case adds a touch of elegance to its design. Each adapter has the following connectivity ports —
- HDMI
- MicroSD Card Reader
- SD Card Reader
- USB-A (2)
- USB-C (PD port)
- Ethernet port (7-in-1 adapter only)

The inclusion of multiple ports made it incredibly convenient to connect various peripherals and expand the capabilities of my device. It eliminated the need for multiple adapters or dongles, streamlining my setup and reducing cable clutter.
I did run a speedtest with a few pieces of media (USB Flash Drive and SD cards) using Blackmagic Disk Speed Test and got the following results.
Media | Write Speed | Read Speed |
---|---|---|
SanDisk 128GB iXpand Flash Drive Go | 33.2 MB/s | 87.8 MB/s |
SanDisk 256GB Extreme PRO UHS-I SDXC Memory Card | 78.5 MB/s | 86.6 MB/s |
SanDisk 256GB Extreme PRO® microSD UHS-I Card | 78.3 MB/s | 87.6 MB/sli |
Conclusion
The Monoprice 7-in-1 and 6-in-1 USB-C Multiport 4K@30Hz HDMI Adapters are reliable and versatile accessories that enhance the connectivity options of USB-C devices. Their impressive 4K@30Hz HDMI output, multiple ports, sturdy build quality, and convenient charging capabilities make them a valuable addition to any setup.
