This USB C + lightning male connector dual card reader features one SD slot and one Micro SD slot (not readable simultaneously), supporting transfer speeds up to 20MB/S–30MB/S. Built with ABS material, it is sturdy for daily heavy workloads yet compact for portability. With OTG-style two-way transfer, you can easily move photos, videos, and office documents between memory cards and devices, accessible directly via the “Files” or “File Manager” app. Plug-and-play design means no drivers, apps, or internet are required. Compatible with USB-C interface for Apple devices (such as for iPhone 17/16/15/14/13/12/11 Pro Max/X/8/7, for iPad Air/Pro/Mini) and Lightning interface for Apple devices, as well as compatible for Samsung Galaxy S25/S24/S23/S22/S21/S20 Ultra, Android phones, tablets, and computers. Important notes: this reader cannot read two slots simultaneously (to prevent interference and ensure stability); actual speed depends on the memory card; and the lightning port only supports iOS 13 and above.
