Number of USB Type C ports for connecting peripheral devices provided in the hub design (or a card reader with hub functionality — see "Type").
The port itself is small — only slightly larger than microUSB — with a reversible design that allows the plug to be inserted in either direction. This is why it has gained respect and is actively replacing the classic USB port.
Despite its small size, USB Type C is used in both portable devices and desktop PCs and their peripherals. However, few such devices have been released so far; as a result, hubs typically include
1 USB C port or
2 type C inputs.
The USB connector interface (version) primarily determines speed.
— 2.0. The outdated 2.0 version provides data transfer speeds up to 480 Mbps. Found only in USB A ports.
— 3.2 gen1. Previously named standards 3.1 gen1 and 3.0. This version ensures a tenfold increase in maximum speed (4.8 Gbps) and higher power capacity, allowing for the connection of energy-intensive devices and extensive splitters.
— 3.2 gen2. A further improvement of the 3.2 gen1 standard (and typically, with several renamings from the previous 3.1 gen1 and simply 3.1), achieving a maximum speed of 10 Gbps and even higher power capacity for external devices.
However, the final speed depends not so much on the input port as on the USB version of the hub (card reader) connection to the PC.
The technology allows you to work at higher voltage, thereby increasing the transmitted power.
USB hubs with Power Dlivery can not only charge smartphones faster, but also power more power-hungry devices, such as laptops.
The length of the cable supplied with the device. Mostly relevant for models with a non-removable cable that cannot be replaced.
