The OEM USB Type-C to USB OTG adapter is a small adapter that connects a device with a USB Type-C port to a USB On-The-Go (OTG) port. With USB OTG technology, devices such as smartphones, tablets, and other portable devices can function as a host or connect to other portable devices, such as USB flash drives, external hard drives, and cameras.

The USB Type-C to USB OTG adapter allows the device with a USB Type-C port to read/write data from/to connected USB devices, such as USB flash drives or keyboards. It is useful for transferring photos or other files from the smartphone to a flash drive or for connecting a mouse or keyboard to the device for easier control.

It is important to ensure that you purchase a reliable adapter from a manufacturer that provides certified products to avoid compatibility issues or potential security problems.
