The product you're describing is likely an 8-in-1 USB Type-C to HDMI adapter or cable, packaged in a black and yellow box. It's designed to connect devices with a USB Type-C port (such as laptops, smartphones, or tablets) to an HDTV or monitor with an HDMI input. This type of adapter usually offers multiple ports in addition to HDMI, such as USB-A, USB-C, Ethernet, SD card slots, and more, providing users with versatile connectivity options.

Certainly! A "USB to LAN" adapter is a device that allows you to connect a device with a USB port to a wired Ethernet network. It's often used for devices without built-in Ethernet ports or for stable wired connections. The "standard green" likely refers to the color of the Ethernet port on the adapter, which is typically green.
