HyperDrive Duo Pro is a 7-in-2 USB-C Hub that plugs into the side of a MacBook to add a variety of ports, including Gigabit Ethernet, USB-A and microSD.
It’s designed to not interfere with the new MagSafe 3 power port on the 2021 MacBooks, but the hub is also compatible with any Apple laptop going back to 2016.
