Made for completing daily tasks with the utmost convenience and least bulk, Microsoft released the ultra-thin Surface Go. To maintain its style, Surface Go only has a single USB-C port - not really helpful if you want to charge and connect other devices while working. That’s where the ADAM elements CASA Hub S4 comes in. CASA Hub S4 lets you instantly expand your Surface Go thanks to its USB-A 3.1, USB-C PD 3.0, 4K HDMI, and 3.5mm audio ports. Simply plug the hub to your Surface Go via USB-C input and experience cutting-edge expansion in just a second! CASA Hub is ultra-light at 0.74oz and is 3.4" long. This multi-port hub sports a beveled design to match the sleekness of your Surface Go.
