In an era where laptops are getting thinner and manufacturers include fewer ports and connectivity options on PCs, it’s becoming harder and harder to hook up as many as three or more devices and accessories to laptops simultaneously. Thanks to technology advancement though, as well as the introduction of Hubs, Adapters, and Thunderbolt 3 Docks (also called Thunderbolt 3 Docking station), laptop owners can connect as many devices as they want to their PC while still enjoying snappier transfer speeds, extreme power transmission, and fast connectivity of the ThunderBolt 3 technology.

So it doesn’t matter if your laptop has only one Thunderbolt 3 port and you have about four(4) different devices/accessories to connect to it, a Thunderbolt 3 dock got you covered. You don’t need USB-C adapters for every device that you own; these docks solve the dongle dilemma you might be facing. Simply plug a Thunderbolt 3 dock into a compatible port on your computer and connect as many devices as the dock support.
