UGREEN SD card reader, aluminium

What to know

Moving photos or video off a camera or dash cam can be awkward when your device has the wrong port. This UGREEN card reader offers both USB-C and USB 3.0 Type-A connections, so you can transfer files to compatible phones, tablets and computers without carrying a separate adapter for each port.

It supports SDHC, SDXC, MMC and UHS-I cards, as well as microSD cards. The listed maximum transfer rate is 5Gbps, actual transfers also depend on the card and the connected device.

Keep in mind that FAT32 and exFAT are the stated supported card formats. If your card uses another format, the listing doesn’t confirm that it will work. The reader can access two cards at once and exchange data between them, which is handy when copying files without repeatedly unplugging one card to insert another.

Best use cases

This is most useful if you move camera or dash-cam files between cards and devices with different ports. For example, you could connect a microSD card and an SD card together to copy files between them, or plug in a card to transfer photos to a compatible phone or laptop. The USB-C and USB-A plugs make it more flexible than a single-port reader, though the device still needs to support the connection being used, OTG is mentioned for phones and tablets.

It’s listed as compatible with iPhone, MacBook, iPad, Galaxy S26/S25, Tab 7 and XPS 13/15. Treat those as named examples rather than a complete compatibility guarantee, especially if your device or operating system differs.

Tips for day-to-day use

There’s no driver installation or additional power required for the stated Windows, Mac OS and Linux support. The compact design, protective caps and lanyard make it easier to pack for travel or keep attached to a bag. Its aluminium casing is intended to protect the reader, but the small plugs are still worth capping when it’s loose in a pocket or bag.

For a large batch of files, the transfer-rate figure is a maximum rather than a promise of a particular copy time. If speed matters, the card and host device need to be considered too. If you mainly use one card format and one type of port, a simpler reader may be enough, this model’s main practical advantage is having both plug types and two-card access in one compact unit.

Buying questions

Can it read two cards at the same time? Yes. The listing says it can read and write two cards simultaneously and supports data exchange between them.

Does it need a driver or separate power? No driver installation or additional power is required for the listed Windows, Mac OS and Linux use.

Which card formats are supported? The stated file-system formats are FAT32 and exFAT. The card types listed include SDHC, SDXC, MMC and UHS-I, plus microSD.

Is it worth it?

It’s a good option if you regularly move files from SD or microSD cards and want both USB-C and USB-A connections without carrying separate readers. The ability to work with two cards at once is useful for transfers between card types, not just moving files to a computer. It won’t suit you if your cards use a format other than FAT32 or exFAT, or if your device doesn’t support the connection you plan to use. Check those details before choosing, the dual-plug design is most valuable when you’ll actually use both.
