UGREEN USB 3.0 Dual Card Reader: 5Gbps Speed & Simultaneous Dual Slot Access

The UGREEN USB 3.0 to TF + SD Dual Card Reader (Black) simplifies media workflows by giving your desktop or laptop instant access to flash memory media. Distributed by Keyphantom, this adapter provides an essential link between digital cameras, dash cams, drones, and host computers.

5Gbps Throughput & Simultaneous Dual Slot Processing

Leveraging USB 3.0 technology, this card reader delivers read/write data throughput up to 5Gbps.
