A Type-C to USB adapter allows you to connect a device with a USB Type-C port (like a laptop, smartphone, or tablet) to a standard USB port (usually Type-A). This adapter enables compatibility between devices that use different USB connectors, such as plugging a Type-C device into a computer or charger that only has USB-A ports.
In summary, it allows seamless connection between newer devices with USB-C ports and older devices or accessories with USB-A ports.
