A USB Hub 4 Port 3.0 with 1-meter cable is a device designed to expand the number of USB ports on your computer or other devices. It allows you to connect multiple USB devices to a single USB port. Here are some key features and details about such a hub:

1. 4 USB 3.0 Ports: The hub provides four USB 3.0 ports, which offer faster data transfer speeds compared to USB 2.0 (up to 5Gbps, depending on the device connected).

2. 1 Meter Cable: The hub comes with a 1-meter USB cable, allowing flexible placement and connecting the hub to your computer or other USB-enabled devices.

3. Backward Compatibility: It is typically backward-compatible with USB 2.0 and USB 1.1 devices, although those will operate at slower speeds (USB 2.0 speeds or lower).

4. Plug-and-Play: Most USB hubs are plug-and-play, meaning you don't need to install any drivers. Simply plug it into your device, and it should work.

5. Power Supply: Some USB hubs are bus-powered (powered through the computer's USB port), while others may require an external power source to support power-hungry devices like external hard drives.

6. Compact and Portable: These hubs are generally compact, making them easy to carry around if needed.
