USB C HUB Multiport Adapter GIISSMO 7-in-1 USB C Adapters with 4K HDMI, 100W PD and USB 3.0, 2 USB-A, SD/TF Card Reader, Compatible with MacBook Pro Air XPS HP XPS and More Type C Device

This has proven to be a very nice Hub for the price. The metal housing gives a sense of quality and makes for a good heat sink when called for if using multiple devices at once. The one weakness found is in the SD card slot. My first Hub had a faulty SD card slot and failed after only two uses which I found was due to broken plastic guides internally. Once I contacted Giissmo support, they responded immediately and sent a replacement. The replacement works well and does not seem to have the SD card problem, but I am cautious in how I insert a SD card. The Micro card slot works fine. All other ports, USB, C, HDMI work fine as well. The 100 watt charging capacity I have not tried, but with the good heat dissipation of the metal shell I expect no problem. My experience with the support group can not be beat.

A compact and versatile adapter. I keep it in my backpack for whatever and whenever. Love it!

This is a very worthwhile purchase, and the quality is very good. My computer is a Macbook air, and it has no problem at all. The three USB ports can meet my daily use. The quality of the adapters I used before was not very good, but the quality of this product is very good. I think this purchase is worth it and this adapter has five different types, very practical as a student who often uses computers and other electronic devices

Limitations: Among the three type A ports, only one is USB3 superspeed, the other two are not.

I needed a small, lightweight portable USB-C hub for my MacBook Pro M1 that I could carry back and forth to the office and to client sites. This hub from GIISSMO did the trick! The HDMI connection is stable, and the power delivery is enough to charge my MBP using an Apple USB-C power cable. I had no problems connecting a USB-A flash drive; both USB-A ports functioned perfectly. Honestly, I haven't had a reason to use the SD card slots, but as well as everything else works, I'm sure that one will work as intended too. The hub does not overheat and stays pretty cool while in use. It is very lightweight, and slides into my tech pouch easily without taking up very much room. For less than $20, this hub is a steal!NOTE: If you need more than one HDMI port, or a DisplayPort connection, this hub is not the one for you. It only has one HDMI port.

Works great on Dell latitude 7320 that has only usb A port. Now I have three extra ports. Display port works great on a 4K monitor. Great value at under $10

The product works. I used the HDMI and USB-C and USB-3 and USB-2 ports successfully. I did not try the SD card slots. However, the problem was when this adapter is plugged into my 2021 Dell XPS laptop (even without any peripherals plugged into it), it causes the reboot cycle to take FOREVER. To be clear, when this adapter is not plugged in, the laptop takes 30 to 35 seconds to restart; however when this device is plugged in; it will take 10 to 15 minutes, and sometimes never completes without a hard reset. Unfortunately, I didn’t realize this was the problem until after the return window closed. So, this device is off to the landfill. I have since bought other adapters (Selore and UGREEN) that do not cause the reboot lag.

I was worried that the space between two USB port would not be enough to fit two of the USB cable side by side but I am happy that it don't have that problem. It works absolutely fine. The cord length is exactly what I needed it to be. Even the charging port works with the high speed.Definitly Recommended.
