This 3-in-1 USB C adapter combines an SD card slot, a Micro SD (TF) slot, and a USB C charging port (charging only). It supports charging while transferring, with transfer speeds of 20MB/s–30MB/s. It cannot read both slots simultaneously, which helps prevent interference and ensures stable transfer. Actual speed depends on the storage card. Once connected, your files appear directly in the “Files” or “File Manager” app, with support for two-way transfer between card and phone. Made from strong ABS, it is resistant to wear, lightweight, and portable. Compatible with USB-C interface devices such as for iPhone 16/15 Pro Max, for iPad 10, for iPad Air 4/5, for iPad Mini 6, for iPad Pro 12.9, and compatible for Samsung Galaxy S25/S24/S23/S22/S21/S20 Ultra, plus Android phones. You will receive one adapter along with full after-sales service: 60-day refund, 1-year warranty, and free replacement for quality issues.
