It combines “USB-C data transfer/charging” with “Micro SD card reading” in one device, precisely addressing modern digital pain points. One end features a USB-C port that seamlessly connects to phones, tablets, laptops, and more—efficiently handling everything from emergency phone charging to rapid work file transfers. The other end features a Micro SD card slot: For users facing storage shortages on their phones, there’s no need to rely on a computer. Simply use the wristband’s data cable to directly access photos, videos, and documents stored on the card, instantly “expanding” your device’s storage capacity. When shooting on the go, you can also quickly transfer footage from your camera’s memory card to your phone, enabling timely sharing of your creations. This eliminates both “storage anxiety” and “transfer hassles” at once.
