Next up in our Best SD Card Reader reviews, Anker is fast becoming one of the most popular tech accessory brands in the USA. That is because they offer high-quality devices that perform correctly for an affordable price. And this SD card reader has all those qualities.

Appearing like a slightly overweight USB thumb drive, the Anker SD 2-in-1 SD card reader has a solid feel to it. It is shorter than our previous two products, only slightly longer than the width of an SD card when plugged in, but is also wider.

While your PC will require an available USB-C port to plug the device into, there are some advantages. USB-C offers higher power output and super-fast data transfer speeds of up to 5Gbps.

Compatible with PCs, smartphones, and tablets…

There is a large range of devices the Unitek card reader is compatible with. It works with PCs running Windows 8 and above and Macs running iOS 10.1 and above. You can also connect directly to Android smartphones and tablets running 6.0 and higher.

The device connects to your PC using a 2.5-foot braided USB cable for extra strength and tangle-free storage. Each of the ports and slots can support a card or drive with up to 2TB of storage space.

Four card slots are capable of reading a wide range of media cards. These include SD, SDXC, SDHC, micro-SD, micro-SDXC, micro-SDHC, UHS-I, CF, and Sony MS. There are also three USB 3.0 ports available for use with various devices.

And there’s still more…
