Source: Windows Central The CalDigit Element hub is made by the same company that makes the formidable CalDigit TS3 Plus Thunderbolt 3 dock, our pick for the overall best laptop docking station. The Element hub is sized smaller and priced lower than some of the other Thunderbolt 4 options, making it a good choice if you lack space on your desktop. It does require a substantial AC adapter, so don't expect to take it with you on the road without quite a bit of bulk. The host laptop plugs into the side of the dock and opens up seven extra ports. The front edge is four USB-A 3.2 (Gen 2) with 10Gbps speeds and 7.5W of charging power. The back edge holds the AC input and three Thunderbolt 4 ports with 40Gbps speeds and 15W of charging power. While connected, note that the host laptop will receive up to 60W charging power when needed.
