The UGREEN Multi-function Card Reader Case (CM856) is a sophisticated utility designed for photographers, videographers, and content creators who cannot afford to compromise on data accessibility or card safety. By merging a high-performance card reader with a protective armored case, it eliminates the need to carry separate storage wallets and adapters, keeping your entire memory ecosystem organized in one compact footprint. Performance is at the core of this device, offering transfer speeds up to 5Gbps via USB 3.0 / USB 3.1 Gen 1. It features a native USB-C interface for modern devices like MacBooks, iPads, and Android tablets, while including a USB-A adapter to ensure seamless compatibility with legacy desktop PCs and laptops. Efficiency is further enhanced by its simultaneous dual-card reading capability. Users can read two cards at once (SD1 + TF or SD1 + SD2), utilizing the UHS-II protocol for fast and stable data access. This makes it an ideal tool for real-time VLOG editing and quick on-site backups without the interruption of swapping cards. Built for the rigors of field work, the case is constructed from shock-resistant silicone that protects against drops and loss. Internally, it provides dedicated slots for 6 SD cards, 4 Micro SD cards, and 1 SIM card, and even includes a SIM ejector pin for added convenience. Safety is prioritized through a low-heat design that maintains an operating temperature of approximately 30.9°C, complemented by built-in overcurrent and short-circuit protection. With plug-and-play functionality across Windows, macOS, and Linux, the UGREEN Multi-function Card Reader Case is a reliable, professional-grade companion for any digital creator.
