Review on 🔌 StarTech.com USB C Multiport Adapter - USB-C to DVI-D (Digital) Video Adapter with Power Delivery, GbE, USB-A - Portable USB Type-C/Thunderbolt 3 Mini Laptop Dock (DKT30CDVPD) by Michael Bustamante

If you have an HP Specter 360x with two USB-C ports on the right side of the laptop (and they have jagged arrows on them), it works. I bought a USB-C power adapter and plugged it into the hub. I then connected the hub to my laptop via USB-C. The laptop is said to use the HP Power Brick, but. It still charged my laptop. I then connected two HDMI 1080p monitors and they both connected straight away. Can't say yet that it will work with dual 4k monitors but hopefully in a few months.
