How to use

Insert the USB-A end of the adapter into an available USB-A port on the host device. Plug the USB-C device (for example a flash drive, smartphone cable, or external SSD) into the USB-C connector on the adapter. The host should recognize the connected device automatically and allow file transfers at USB 3.0 speeds where supported. No software installation is typically required for standard file and peripheral access.

Usage recommendations

Use the adapter with devices that require standard USB data connectivity; avoid relying on the adapter for high-current charging or features that require USB-C power delivery negotiation. For sustained high-performance use with external drives, connect through a port that supports USB 3.0 or higher on the host. Store the adapter in a protective pouch to prevent dust or damage to the connectors when not in use.
