After inserting a memory card, you can access files directly in the “Files” or “File Manager” app, with support for two-way transfer between storage card and device. Crafted from durable ABS material, it resists daily wear and ensures stable performance. Compact and lightweight, it is easy to carry for work, study, or travel.

Notes: This card reader cannot read two slots at the same time; the USB-C female port is for charging only; read speed depends on the card used.
