## Key points

- Teal often indicates USB 3.1 Gen 2 or newer.
- USB 3.1 Gen 2 supports speeds up to 10 Gbps.
- Port colours are not a reliable specification.

## Summary

Teal USB-A ports are commonly associated with USB 3.1 Gen 2 or later, which can offer faster data transfer and greater power output. This can make them useful for moving large files and charging smaller devices, though the colour is only a guide and does not guarantee a particular specification.

USB 3.1 Gen 2 can reach speeds of up to 10 Gbps and is generally backward compatible with older USB-A devices, which may operate at their own lower speeds. Some red USB 3.2 ports can reach 20 Gbps; to check a port’s actual capabilities, users can consult Device Manager on Windows or System Report on macOS.
