Hyper has a new USB-C hub, and it’s a pretty clever twist on the usual hubs we’ve seen. Instead of plugging your charger into a separate hub, the HyperDrive USB-C Hub Attach attaches (get it?) to the charger for a more seamless setup than a dangling dongle.

It’s similar to the TwelveSouth’s PlugBug, which attaches to the plug end of Apple’s MacBook chargers to add USB Type-A ports for charging. But the HyperDrive USB-C Hub Attach goes a step further by actually serving as an active USB-C hub. It lets you not only use the two extra ports for charging, but you can actually connect them to your computer for data transfer, too.
