Manufacturer description
The Acer SD Card Reader turns any spare USB-A port into a dual-slot card bay for SD and Micro SD media, and it does it without drivers. The USB-A 3.0 interface runs at 5Gbps, so offloading a shoot's worth of photos or 4K clips to your laptop takes minutes rather than a coffee break, and backward compatibility with USB 2.0 and 1.1 means older machines still work. Both slots are live at once, so you can read from an SD card and write to a Micro SD card in the same session instead of swapping media between transfers. The aluminum shell is slim enough to ride in a camera bag or jacket pocket…

Frequently Asked Questions
How fast is this Acer SD card reader?
The USB-A 3.0 interface is rated for 5Gbps. Real transfer speed depends on your card; a UHS-I card will be the limiting factor, not the reader.
Can I use both card slots at once?
Yes. The dual slots support reading and writing on an SD card and a Micro SD card simultaneously, so you do not have to swap cards mid-transfer.
Will it work with my MacBook or iPad?
It connects over USB-A only. It is not compatible with USB-C or Lightning ports, so a USB-C Mac or an iPad needs a USB-A adapter or hub.
Do I need to install drivers?
No. It is plug and play on Windows, macOS, Chrome OS and Linux with no driver download required.
Does it support CF, XQD or V90 cards?
No. Supported formats are SD, SDHC, SDXC, MMC, RS-MMC, Micro SD, Micro SDHC, Micro SDXC and UHS-I. CF, XQD, SDUC, UFS, mini SD, MS, SIM and V90 are not supported.
