Features
Broad Compatibility: The defining feature of a universal stylus is its wide compatibility with most capacitive touchscreen devices, such as those running iOS, Android, and Windows. They do not rely on a specific, proprietary connection protocol (like some brand-specific active pens).
Capacitive Technology: Most universal styluses are "passive" or "capacitive" styluses, meaning they mimic the electrical conductivity of a human finger. This allows them to work on any standard modern touchscreen without special software or pairing.
