USB 4.0 UHS-II V90 SD/TF Multi-function 2-in-1 High-Speed ​​Card Reader for Mobile Phones, Computers, and Laptops - USB Port

SD / SDHC: Supports standard-size SD cards and high-speed SDHC cards, the most commonly used memory card types in digital cameras and camcorders.

MiniSD / Mini SDHC: Supports the smaller MiniSD card and its high-speed version (now less common, but compatible with older devices).

MicroSD (TF): Supports microSD cards (TF cards), the most popular memory card used in devices such as smartphones, action cameras, drones, and dashcams.

RS-MMC: Supports Reduced-Size MultiMediaCard, an older standard compatible with some older phones and devices.

Ultra-Speed ​​Transfer: The USB 4.0 interface has a theoretical maximum speed of 40Gbps (requires host and device support). Even if it doesn't reach this theoretical peak speed, it still far exceeds traditional interfaces like USB 3.0 and USB 2.0.

Significant Time Savings: When transferring large files (such as 4K/8K videos, RAW photos, and large document backups), a high-speed interface can significantly reduce waiting time and improve work efficiency.

Backward Compatibility: The USB 4.0 interface is fully backward compatible with USB 3.2, USB 3.0, and USB 2.0. Even if your computer doesn't have a USB 4 port, it will still work properly, though the speed will be reduced to the maximum supported by your computer's interface.

Plug and Play: No complicated drivers or software installation required; it's instantly recognized when connected to your computer's USB port, making it incredibly easy to use.

Portable: Its compact size makes it easy to carry, slipping easily into a pocket, backpack, or computer bag, making it an ideal companion for mobile work and travel.

USB Port Model: Features a standard USB-A port, compatible with most desktop and laptop computers.

Type-C Port Model: Features the latest USB-C port, compatible with new laptops, MacBooks, tablets (such as the iPad Pro), and smartphones.

USB + Type-C Port Model: Highly recommended. Featuring both USB-A and USB-C connectors on each end of a single cable, it's compatible with both new and older devices without the need for adapters, providing maximum flexibility.
