On-the-Go Card Reader for USB-C Devices

The UGREEN 80124 is a portable Micro SD card reader built for USB-C phones, tablets and laptops. It lets photographers, drone pilots and dash-cam users offload footage directly in the field without a computer. The zinc-alloy body includes a key-chain loop so the adapter stays with your keys or bag.

UHS-I Speed up to 104 MB/s

The single specification that decides fit is the UHS-I interface, which delivers up to 104M/s over the USB 3.1 Gen 1 5Gbps link. If your Micro SDHC or SDXC card is rated UHS-I you will see the full benefit; slower cards will run at their own limit and faster UHS-II cards will not reach their peak.

Driver-Free Plug-and-Play with Case Clearance

No software installation is required on iPad Pro, MacBook, Samsung Galaxy, Google Pixel or other USB-C hosts. The reader accepts phone cases up to 1.8mm thick, so most slim covers stay on during transfers. Zinc alloy dissipates heat better than aluminium, so the shell may feel warm during sustained reads — this is normal operation.

Questions about this item

How fast will my Micro SD cards actually read and write when I plug this reader into my laptop?

The adapter reaches up to 104 megabytes per second with UHS-I cards, roughly ten times the speed of USB 2.0.

What does the USB-C connector limit me to in real-world use?

The USB-C plug supports 5 Gbps signalling, so the reader’s 104 MB/s ceiling is the practical bottleneck, not the port.

Will this stick out too far or block adjacent ports on my MacBook?

The zinc-alloy body measures 1.7 by 6.9 by 9.8 centimetres and weighs 20 grams, leaving plenty of clearance beside other ports.
