Ultrabooks are great until you need to start plugging things in. That’s where this powerful Thunderbolt 3 dock from HP can save the day. It provides an extra three USB 3.0 Type-A ports, a VGA port, an Ethernet port, two full-size DisplayPort connections, and three additional USB-C ports for an additional display, charging, or other Thunderbolt 3 devices. This turns the HP Spectre into a true workstation.
