4-in-1 SD TF USB Adapter Reader

Measures 7.5 × 3.2 × 1.1 cm and weighs 28 g. Accepts standard SD cards and microSD (TF) cards, supporting capacities up to 2 TB. Integrates four distinct physical interfaces: full-size SD card slot, microSD (TF) card slot, USB-C male port, and Micro-USB male port. Uses USB 2.0 protocol for data transmission (max 480 Mbps), ensuring wide OS compatibility and stable performance. Constructed with flame-retardant ABS shell and nickel-plated copper contacts for long-term conductivity. Functions as a standard USB mass storage device — no drivers, no apps, no internet connection required. Confirmed compatible with Windows (10/11), macOS (Monterey to Sequoia), Android (9–14 with OTG), and Chrome OS (v115+). Solves everyday UK-specific data bottlenecks: transferring scanned documents from SD-equipped scanners to Surface Pro tablets; moving drone footage from microSD to MacBook Air for editing; or loading firmware updates onto Raspberry Pi SD cards via a USB-C laptop. Its low-power draw (≤100 mA) ensures stable operation even on power-limited USB hubs or older laptop ports. The balanced weight distribution and flat base allow stable upright placement beside keyboards or on narrow hotel desks — avoiding the tipping issues common with asymmetrical multiport readers sold on Amazon UK.
