The CM296 USB-C Multifunction Hub is shaped like a worry stone and features an M.2 hard disk integrated into the casing which supports the Power Delivery fast charging protocol, making it compatible with all PCs that have a USB-C port. It is made of an aluminium alloy that dissipates heat and has two rows of holes in the upper and lower shell to provide ventilation inside and ensure stable transmission. Rubber is also used to insulate relevant parts.
