15cm long design provides flexibility and sufficient length to extend and read SD cards. Supports conversion of TF (Micro-SD) memory cards to SD memory cards, ideal for applications such as car GPS navigator data upgrades or instrumentation data updates. Fast reading speed: the extension cable does not affect the read and write performance of the device, maintaining optimal efficiency. Can be used as an expander or linker when your device has a built-in micro-SD card slot and you need to externally connect a larger SD memory card. Cable is flexible and easy to install.
