GREEN 4-in-1 Card Reader (USB-C & USB-A) – CM812

The UGREEN CM812 is a versatile, high-speed data transfer solution for photographers, videographers, and power users. Designed with a convenient 2-in-1 interface, it allows you to move files seamlessly between modern USB-C devices (like smartphones, tablets, and newer laptops) and traditional USB-A computers without needing separate adapters.

UGREEN CM812 Key Product Features

• Dual Interface Versatility: Features a hybrid connector that flips between USB-C and USB-A 3.0, ensuring universal compatibility across your entire tech ecosystem—from your high-end workstation to your mobile devices.

• 4-in-1 Card Slots: Equipped with four slots (SD, Micro SD, CF, and MS cards), it supports the most popular memory card formats, eliminating the need for multiple readers.

• Simultaneous Data Access: Unlike many entry-level readers, the CM812 allows you to read from or write to multiple cards simultaneously, which is a massive time-saver when backing up footage from a multi-camera shoot.

• SuperSpeed Transfers: Utilizing the USB 3.0 standard, it supports data transfer rates up to 5Gbps. This ensures high-resolution RAW photos and 4K video files are transferred in seconds rather than minutes.

• Plug-and-Play & Portable: No external power or driver installation is required. Its compact, durable design makes it the perfect field tool for photographers needing to offload footage on location.
