Compact dual-interface card reader

The Radidi K047 is a lightweight SD and microSD card reader with both USB-A and USB-C connectors. It suits photographers, drone operators and security-camera users who need to offload files quickly from multiple card formats without carrying separate adapters.

Check host port and card compatibility

Verify that your device offers a USB-A or USB-C port and supports the card type you use: SD, SDHC, SDXC, microSD, microSDHC or microSDXC up to 2 TB. The reader accesses only one slot at a time, so plan workflows that swap cards rather than expecting simultaneous dual reads.

Fits mobile and desktop workflows

Plug the reader directly into a laptop, tablet or phone to view footage and transfer files without extra cables or software. Its pocket-sized form factor frees up desk space and eliminates the need for a camera’s proprietary transfer app or Wi-Fi link.

Questions about this item

Does the Radidi K047 include any memory cards or do I need to buy them separately?

Memory cards shown in images are not included; you must supply your own SD, SDHC, SDXC, microSD, microSDHC or microSDXC cards up to 2 TB.

Should I choose the USB-C or USB-A connector for the fastest transfer on this K047?

Both the USB-C and USB-A interfaces support the same high-speed data transfer up to 480 Mbps, so either connector gives identical performance.

What does the 480 Mbps rating mean when I copy a 1 GB file with the K047?

At 480 Mbps the adapter can move a 1 GB file in a few seconds, letting you download photos, edit video or transfer 3D-printer files without waiting.
