About USB Type-A

USB Type-A is the original and most common USB connector type. It's a flat, rectangular interface that typically appears on host devices such as computers, game consoles, and many other electronic devices that supply power or serve as the primary controller in a connection.

The USB-A connector is designed to work with various USB standards, including USB 1.1, USB 2.0, and USB 3.0. USB 3.0 variants can be identified by their blue internal color and additional pins for extra bandwidth.

Key features include:

• Simple four-pin design for data and power transmission
• Standard 5V power delivery with current varying by USB version
• Plug-only design (USB-A receptacles are never found on cables, only on host devices)
• Durable construction with typical lifespan of thousands of insertion cycles
• Compatible with a wide range of devices across multiple USB generations
