UGREEN Magnetic 3-in-1 USB-C SD 4.0 Card Reader 312MB/s with 100W PD Charging Space Gray | CM898
The UGREEN CM898 is a compact magnetic card reader with one SD and one microSD (TF) slot plus a USB-C PD charging port. It supports SD 4.0 (UHS-II) speeds up to 312MB/s and passes through up to 100W, so your phone or laptop can charge while you transfer files.
Color: Space Gray
Description:
SD 4.0 speed up to 312MB/s: The SD 4.0 / UHS-II slots reach up to 312MB/s with a UHS-II card, about three times faster than SD 3.0 (104MB/s). It is backward compatible with slower UHS-I cards, which run at their own speed.

Charge and transfer at the same time: A USB-C PD port on the reader accepts a charger and passes up to 100W to the connected device. Your phone's only USB-C port is no longer blocked: you can import files and charge at once. The magnet itself does not charge; you must connect a charger to the PD port.

Magnetic attachment: The reader sticks magnetically to the back of iPhone 15 and later models or to a MagSafe case, so it doesn't dangle while you work. For other phones or cases, use the included magnetic ring.

Use two cards together: The SD and TF slots can work independently or at the same time, so you can copy between a camera card and a microSD card without swapping.

Wide card and device support: It reads SD, SDHC, SDXC, microSD, microSDHC and microSDXC cards, including UHS-II, with capacities up to 2TB. It works with USB-C phones, tablets and laptops such as iPhone 15/16, iPad, MacBook and Samsung Galaxy, with no driver needed.

Aluminum, thin and light: The aluminum alloy body measures about 61 × 61 × 12 mm, so it fits easily in a small bag or pocket.




Works With:
USB-C devices: iPhone 15 and later USB-C models, iPad, MacBook, Samsung Galaxy and other USB-C phones, tablets and laptops (Windows, macOS, iOS/iPadOS, Android). Not for USB-A ports.
Good to know: Memory cards and charger are not included. 312MB/s needs a UHS-II card; UHS-I cards are slower. Direct magnetic hold needs iPhone 15 or later or a MagSafe case; other phones need the included magnetic ring. Charging only works through the reader's PD port, not the magnet. Phones/tablets must support OTG storage.
