Review on Satechi Aluminum Multi-Port Adapter 4K HDMI, USB-C Pass Through, Gigabit Ethernet, SD/Micro Card Readers, USB 3.0 - Compatible with 2020 MacBook Pro, 2020 MacBook Air, 2020 iPad Pro (Gold): Enhance Connectivity and Functionality by Matt Venable

Works with DELL XPS 15 (9550) HDMI, USB 3.0, Ethernet. I haven't tried using the USB-C power transfer feature and the SD/mini SD card slot. . HDMI works well with WUXGA (1200 x 1920), but I didn't test FPS at 4K (60 or 30) because I don't have a high-resolution display. USB 3.0: My wired keyboard and mouse work with this product. My mouse isn't a gaming mouse, it's a regular three-button mouse. So I don't know if it will work with high-end keyboards/mice like gaming products. It also works with my iPhone 5s via a lightning USB cable, including charging and iTunes. Ethernet: Fully functional at 650 Mbit/s download and 900 Mbit/s upload.
