Made for completing daily tasks with the utmost convenience and least bulk, Microsoft released the ultra-thin Surface Go.

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.
