Compact USB-C Card Reader

The ACKSKY USB-C 4.0 Card Reader provides dual slots for SD and Micro SD cards in a metal housing. It connects via USB Type C and supports UHS-II speeds up to 255 MB/s. The compact design includes a short cable to keep adjacent ports free. It suits photographers and mobile users needing fast, portable card access.

Upgrade From Single-Slot Readers

This reader replaces older single-slot adapters by reading two cards at once and supporting UHS-II performance. The jump is worth it when you regularly move data between SD and Micro SD media or need the 255 MB/s ceiling. It also adds USB 3.0 OTG support for direct Android transfers without a computer.

Check Compatibility Before Buying

Verify your Android device has a USB-C port and supports OTG function; iPhone and iPad are not supported. Ensure your memory cards are formatted exFAT if you transfer single files larger than 4 GB. The reader handles SD, SDHC, SDXC, Micro SD, Micro SDHC, Micro SDXC and MMC cards up to 2 TB capacity.

Questions about this item

What USB-C port spacing does the 8.509 cm wide reader need so it does not block the adjacent port?

The reader measures 8.509 cm wide and includes a short cable so it clears the neighbouring USB-C port on most laptops.

How do I enable OTG on my Android device before connecting the reader?

Open Settings, search for OTG, and toggle it on; the reader then mounts SD and micro SD cards without any extra app.

When should I reformat a card to exFAT instead of leaving it in FAT32?

Reformat to exFAT when you need to move single files larger than 4 GB; FAT32 cannot handle files above that size.
