OTG (On-The-Go) Cable: A specialized USB adapter cable that allows a mobile device (like a smartphone or tablet) to act as a host, enabling it to connect to and power standard USB peripherals.

Micro-USB/Male USB-A: A common OTG connector design, featuring a Micro-USB plug (for the mobile device) and a standard female USB-A port (for the peripheral).

USB-C OTG Adapter: A modern version of the OTG cable, where a USB-C connector replaces the Micro-USB end to suit contemporary devices.

Host Mode: The functional state enabled by an OTG cable, where the mobile device supplies power and controls connected accessories like flash drives, keyboards, mice, or game controllers.

Direct Data Transfer: A primary use case for OTG, facilitating direct file transfers between a phone and USB storage devices without requiring a computer or cloud service.

Power Role Reversal: The key function of OTG technology reverses the typical power dynamic so the mobile device powers the accessory instead of being charged by it. Not all devices support this feature.
