Awesome tool to have
Color: Grey
The UtechSmart USB C Ethernet Multiport Adapter is a great small and versatile tool. I use it to connect my Android phone or tablet to an HDMI display that is not a smart device. I primarily use it in my kids' room to watch Netflix or YouTube videos on the larger screen, or in our travel van where I have a display for the kids to watch TV while on long travels.
I love this tool because it eliminates the need for DVDs, which can get scratched and the kids get tired of watching the same movies. With this tool, I can connect their device to the display, and they can watch everything together on the display and listen through my van speakers.
The tool also has other great benefits that I use with my Mac, such as the ability to connect USB devices for external storage, connect to an HDMI display, or connect to Ethernet cables. This is a great tool to have in your computer bag, especially if you use a Mac or any other computer with a USB C port.
Pros:
Small and lightweight
Versatile
Easy to use
Affordable
Works with a variety of devices
Cons:
The HDMI port only supports 4K output at 30fps
The Ethernet port does not support Gigabit speeds
Overall:
I highly recommend the UtechSmart USB C Ethernet Multiport Adapter. It is a great tool for anyone who needs to connect their devices to a variety of displays or peripherals.
Overall, I am very happy with the UtechSmart USB C Ethernet Multiport Adapter. It is a great product that I would recommend to anyone.

Solid USB C Ethernet Hub!
Color: Grey
I was looking for an USB C Ethernet adapter for my new Samsung Galaxy book 2 Pro 360, and the first couple I ordered had the problem of constantly disconnecting and reconnecting. After some digging into the issue, it seems this has been a common problem the plagues USB C adapters, and may be due to the connection being loose, or the hub overheating, and the hub not being able to supply all the power necessary to maintain connection. So I needed a hub that had PD so that power draw would always be sufficient to maintain connection. This hub has worked as advertised, It hasn't disconnected once, and I have plugged 3 external hard drives, in addition to the Ethernet port, and getting very fast speeds, well over 400 Mbps on my 400 Mbps plan, and upload speeds are as advertised as well. So far I am very happy with the purchase, I will update this review once I have used the HDMI port.
Update: 7.15.22
My laptop no longer recognizes the USB Hub. I contacted customer service to request a warranty replacement, and they shipped one out within a couple days. After sthinking about why the first hub failed, I believe it could be a heat issue. I have 3 external USB SSDs connected to the hub along with the Ethernet port, and the USB C power delivery port to provide the necessary power. I notice it gets quite warm, so I have been monitoring the heat, and placing it on a cooling pad, which keeps it from getting too hot. I wish I didn't have to use the cooling pad, but I'm pretty sure that was what led to the other hub failing.

Works pretty well with the GPD Pocket 2 (m3-8100Y refresh)
Color: Grey
I gave this 5 stars because even though it isn't perfect, I think any issues I've encountered are more likely a result of the hardware, software, and drivers I'm using.
TL;DR: It basically works as expected and I can confirm that it doesn't use DisplayLink.
I contacted UTechSmart before purchase to confirm if this device used USB-C HDMI Alt-mode instead of a DisplayLink chip. They confirmed it uses the former and said that though they had not tested it with a Pocket 2, if it didn't work I could return it no questions asked. Bonus points to them for that.
For reference, I'm using it with a GPD Pocket 2 (late 2018 product refresh using an Intel m3-8100Y CPU), running Windows 10 LTSC 2019 and a mixture of GPD and first-party drivers (mostly direct from Intel and Realtek). This is not how it comes from GPD, and is most definitely NOT a supported configuration by either GPD or Microsoft. I'm using the latest Intel drivers available (26.20.100.7000) from the Intel site.
The only persistent issue is that on my device, if second-screen mode default (Win+P) is set to duplicate or extend then neither screen will display when the hub is first plugged in. After a few seconds one of the screens will start working again. If the default is second screen only then it will work immediately. Once external display is working, using the Win+P shortcut to switch to duplicate or extend works correctly. This is most likely a Windows or driver issue.
For reference the Pocket 2 has a 1920x1200 screen that I use at 150% scaling and I mostly used 1920x1080 @100% scale monitors for testing. No HDMI adapters were used and I tested with two different known-good cables. Monitors tested were two Dell S2240L, one LG IPS234, and a Panasonic TCP50GT25. I also tested on a 4k Samsung UN50NU6950 and it reported output 4k@30fps, which is close enough to the Intel UHD 615 spec for HDMI 1.4.
This hub can function without external power, but if you have problems, try connecting power before you connect it to your computer. When I used it for the first time, it wouldn't appear to work without external power, but after some unrelated software and driver updates, now it does. For me, this issue was definitely on the host side, not the hub side.
The network chip is a Realtek RTL8153 USB 3 to gigabit Ethernet adapter. I own several devices that use this chip and it is serviceable, but tends to reset or drop out under sustained gigabit traffic. This is a characteristic of either the chip or Realtek's drivers, and there isn't really anything UTechSmart can do about it. (The other common providers of low cost USB->Ethernet chips (e.g. the ASIX AX88179) often have the same problems.) Below max speed, the 8153 works without any problems. As an aside, if you have one of these chips in a standalone usb adapter, you can plug it into a USB 2 port to get a trouble-free 250-350 Mb/s without having to babysit it.
I haven't tried stress-testing how much power you can get from the USB 3.0 ports, nor have I tried to saturate the USB-C link with simultaneous video, network, and USB SSD file transfer traffic. It doesn't really fit my use case for the device, and if doing so didn't work or caused the hub to drop connection it wouldn't necessarily be the hub's fault anyway.
One feature of the GPD Pocket 2 is that it can charge from any 5V source, not just from a USB-C PD charger. So I tried to power the hub with a regular USB power bank that can output [email protected] (Soshine E3S). When charging directly, the Pocket 2 increases current draw until the voltage begins to sag below 5V. This is normal behavior and prevents the device from pulling too much current from the charger. But when I power the hub and indirectly charge the device, the power bank's over-current protection immediately trips. For whatever reason, the hub prevents the Pocket 2 from noticing the voltage drop in time to prevent a fault. A higher output 5V source, or a proper USB-C PD power bank would probably work just fine. It's just too much for a smaller power bank.
So in summary it works well, the price ($40 at time of purchase) is competitive with other similar products, and if I needed another I would start looking at UTechSmart first.

Utechsmart hasn't let me down a single time!
Color: Grey, Color: Grey
I received my Utechsmart USB-C Hub the other night and I really like it!
I have two different Utechsmart mice, and I've always liked their products.
I did get to test it out with my TypeC Android phone so far and tried out some of the connections.
The quality is really nice on the hub itself. It's a brushed aluminum design, and really smooth- it definitely won't break or snap for sure. All of the ports are sturdy and don't move inside of the housing. I don't see it heating up and getting hot as well.
It also has a calm blue connection light which isn't blinding or piercingly bright at night which is a big plus too. I've used many blue led items in the past, and it's a very soft tactile light and does not illuminate the room.
So, I tested it first with my android phone to 4k TV- WORKED immediately. No software download, no driver install needed. Emulated and displayed my phone to the TV in portrait and landscape (based on orientation.) Just plugged into the HDMI hub and then to my phone and produced native 4k AND sound! Tested with Pandora and YouTube. No noticable latency, either.
Also, the hub accepts 3x USB 3.0 and allowed external storage from a flashdrive to my phone AND allows for USB mouse, when enabled in developer options. If you do any phone gaming, you may have an upper edge with a mouse, or if your screen is broken.
Another really cool thing is that the hub has a female USB-C socket, which allows battery charging as a pass through (with another cable) which I was very surprised to see working.
Overall, I'm extremely pleased with the design and construction and functionality of the hub itself, and the Utechsmart brand in general. Again, I've got two gaming mice from them, and have had them for quite a few years now. Never a single complaint.
:)
