A4TECH Company History
A4TECH was founded in 1987 in Taiwan. Over the years, the manufacturer has accumulated extensive experience in computer peripherals, developed proprietary technologies, and patented a number of engineering solutions. A4TECH products are supplied to more than 50 countries worldwide and are available in various price segments — from budget office devices to gaming series with enhanced specifications.
A4TECH's manufacturing facilities are located in Taiwan and China. The company has its own R&D center focused on developing optical sensors, mechanical switches, and wireless technologies.
A4TECH Proprietary Technologies
Over the years, A4TECH has developed several technological solutions used in its products:
V-Track — Optical Positioning Technology
V-Track is an optical sensor technology that allows mice to work on various surfaces, including glass, lacquered wood, fabric, and glossy surfaces. Unlike standard optical sensors that lose accuracy on smooth or reflective surfaces, V-Track ensures stable positioning without a mousepad. The technology is implemented at the hardware level and does not require additional software installation.
Runner — Fast Charging System for Wireless Mice
Runner technology (also known as Fstyler) allows charging a wireless mouse for 2 minutes to provide up to 3 hours of operation. A full charge takes about 10-15 minutes and provides up to several weeks of operation depending on usage intensity. The solution is relevant for mobile users and office workers who do not want to leave the mouse charging for extended periods.
High-Endurance Mechanical Switches
In the Bloody series, A4TECH uses proprietary mechanical switches rated for up to 60 million keystrokes. The switches provide tactile feedback and shortened key travel, making them in demand not only in gaming but also at workstations requiring high input accuracy (CAD, design, programming).
