Questions, answered
Before you connect.
Compatibility, speed and storage details in plain language.
Which cards can the Freewell Duo Reader read?
It reads and writes one SD card and one microSD/TF card. Supported SD families include SD, SDHC and SDXC, with UHS-I and UHS-II support. The microSD slot supports microSD, microSDHC and microSDXC media.
Can the SD and microSD slots work at the same time?
Yes. An inserted SD card and microSD card can appear as separate drives and operate simultaneously, subject to the host device, available power and total bandwidth.
How fast is the Duo Card Reader?
The reader uses a USB 3.2 Gen 1 host interface rated up to 5Gbps. Actual transfer speed depends on the memory card, data cable, connected port, host device and whether both cards are transferring at once.

Yes. The SD 4.0 reader slot supports UHS-II and is backward compatible with UHS-I SD, SDHC and SDXC cards.
Can it read CFexpress Type A or Type B cards?
No. The Duo Reader reads SD and microSD only. Its CFexpress Type A and Type B positions are protective storage slots. Choose the Freewell Pro Reader if you need to read CFexpress cards.
What can the internal organizer hold?
It stores one CFexpress Type A card, one CFexpress Type B card, three SD cards, six microSD cards, two Nano SIM cards and the included eject pin. The CFexpress and Nano SIM positions are storage only.
Does it work with phones, tablets, Mac, Windows or Linux?
It is plug-and-play with compatible Windows, macOS, Linux, Android and iPadOS devices. Phones and tablets need supported external-drive access, a compatible USB connection and enough power for the cards in use.
