Baseus USB 3.0 2-in-1 SD & microSD Card Reader – Grey

When your laptop skimps on built-in card slots, this Baseus reader steps in with two essential ports and true USB 3.0 speed. Unlike single-slot dongles that force you to swap cards, the GL3224 chipset drives both SD and microSD simultaneously, so offloading a camera and a drone card happens in one pass.

Highlights

• Dual slots: full-size SD and microSD, both active at once
• USB 3.0 SuperSpeed up to 5 Gbps – backward compatible with USB 2.0/1.1
• Supports SD/SDHC/SDXC, microSD/microSDHC/microSDXC, MMC, RS-MMC, UHS-I
• Reads cards up to 2TB – future-proof for high-capacity media
• Plug & play, hot-swappable, bus-powered – no drivers or external power needed
• Blue LED confirms connection and data activity
• Compact ABS housing in grey, fits any workspace or travel kit

In daily use

Plug the reader into any USB-A port and it is ready immediately on Windows, macOS, Linux, Chrome OS, or Android with OTG. Transfer RAW photos, 4K video, or entire music libraries without throttling. The LED glows blue when powered and blinks during transfers, so you always know the status. Because both slots work concurrently, you can copy from an SD card to a microSD card without using your computer as an intermediary.
