The versatility of the USB-C port means, that it can perform several functions, combining video output and power input. But what if you need to use a second display for extended periods of time beyond what you can expect from your laptop's battery life? With the dual-port adapter there is no need to choose between the two! This adapter allows you to connect an external DVI display to mirror your laptop's display or expand your system's desktop area, with support for resolutions up to 1920 x 1080p. It also features a USB-C port, which you can connect to your original USB-C charger, so you can charge the battery while simultaneously using a second display!
