Review on 🔌 LENTION USB C Multi-Port Hub 4K HDMI, 4 USB-A, SD 3.0 Card Reader, Type C Charging Adapter for 2020-2016 MacBook Pro 13/15/16, New Mac Air/Surface, Chromebook, and More (CB-C36, Space Gray) by Mark Hanson

When buying something with USB-C, it's important to know that if a USB-C port is marked with a "PD" Label is present, this also stands for "Supplying Power" and the port probably cannot be used for anything other than charging. In other words, it doesn't extend the USB-C port it's plugged into on an iMac to connect an external SSD, for example. Too bad (probably) that I didn't know that when I ordered this "hub". The worst thing was that the device had 4 USB-A ports, only three of which actually worked. The fourth was dead on arrival. I do not recommend this device to anyone.
