UGREEN CM401 USB-C 2-in-1 High-Speed Card Reader

Fast, Simultaneous Dual-Card Reading in a Pocket-Sized Aluminum Body

The UGREEN CM401 plugs straight into any USB-C port and reads SD and microSD cards at the same time, so you can offload a camera card and a phone's microSD card in one pass instead of swapping cards back and forth. Its USB-C 3.1 Gen 1 interface pushes data at up to 5Gbps, moving photos and video off a card at around 100MB/s — enough to clear a full memory card in a couple of minutes rather than sitting through a slow USB 2.0 transfer.

Card support is broad: SD, SDHC, SDXC, MicroSD, MicroSDHC, MicroSDXC, MMC, RS-MMC, TF, and UHS-I, with capacity up to 2TB per card. A durable aluminum shell paired with a braided nylon cable keeps the reader compact and travel-ready, while an LED indicator shows active read/write status so you always know when it's safe to unplug.

It's plug-and-play with no drivers or apps needed, and works across iPhone 15/16/17 Pro (USB-C models), iPad Pro, Samsung Galaxy, MacBook, and Windows laptops via USB-C OTG. Built-in electrostatic discharge, overcurrent, and short-circuit protection keep both the reader and your cards safe during everyday use.
