USB ports charge.
Relatively cheap, lightweight, and better than most. It gets warm, but not hot. The Video adapter was immediately recognized by my Macbook and works flawlessly at all resolutions made available (much higher than Windows PCs) I used it both as the recipient of my 65W Mac charger, and the Mac received its power from this device; I also had the 65W Mac charger plugged directly into the Mac, and this plugged into the second USB-C plug on the mac. It works (HDMI monitor) both ways. It says that the ports are not for "charging", however be aware that they do charge when devices are connected, for example my iPhone to the extra USB-C port, or the USB-A port. My Logi back-lighted keyboard lights up too. I don't know why they say it is not for charging. Perhaps it is simply saying there are no ports expressly intended to do charging without connecting to your computer.

High quality and all the right connection types
This works great. I've used it for both my MAC and PC. I really love the Ethernet on the end and the HDMI connections (which modern laptops don't include at times). This is a great adaptor and highly recommend.

One complaint
Works very well and solved port issues on my X1 Carbon. My only quibble is that the C interface cable from the unit to the PC is a bit too stiff and tends to lose connection if things move about.

Perfect for my use
Works as intended. Solid build quality and works with my Windows laptop through the USB C connection. I wish the product description would clarify that the USB ports do not support video.
