HUB OX consists of two square USB hubs, each with four interfaces for hard drives, mice, keyboards or monitors. When both hubs are placed under a laptop, it is raised so that heat dissipation on its underside is improved. Since the bottom of the hubs is rubberised, they do not slip and thus provide a secure grip. For transport, the two devices can be plugged into each other. A magnet ensures that they stay connected.
