USB Hubs and Multi-ports

A USB hub is a device that expands the number of USB ports available on your computer. It is useful if your computer does not have enough ports for all your devices (keyboard, mouse, external hard drive, webcam, etc.) or if you want to organize your cables.

A USB hub generally focuses on adding more USB ports. A multi-port hub, on the other hand, combines USB ports with other types of ports, such as HDMI, Ethernet (RJ45), SD/microSD card readers, and sometimes even power delivery (Power Delivery) ports, offering more comprehensive connectivity.

You will mainly find USB-A ports (the classic rectangular ports) and increasingly USB-C ports (smaller and reversible), which support faster data transfer speeds and advanced features like fast charging.

No, not all of them. For a multi-port hub to be able to charge your laptop, it must have a USB-C port compatible with Power Delivery (PD) technology and be powerful enough (expressed in Watts) to meet your device's needs.

To choose, first determine the number and type of ports you need (USB, HDMI, Ethernet...). Then, check compatibility with your devices (USB speed, video resolution for HDMI, PD charging power). Finally, make sure it is suitable for your operating system (Windows, macOS, Linux).

The vast majority of hubs are universally compatible thanks to USB standards. However, for advanced features like video via USB-C (DisplayPort Alternate Mode) or Power Delivery, it is important to check the specific compatibility of your laptop with these technologies.
