Engineered for Elite Performance
The DeathAdder V4 Pro is the first mouse to feature Razer HyperSpeed Wireless Gen 2—delivering an ultra-stable connection, over 63% greater power efficiency, and 37% lower latency than its predecessor. Thanks to this breakthrough in wireless technology
and a redesigned dongle optimized for peak performance, it ensures lightning-fast responsiveness at up to 8000 Hz in both wired and wireless modes. All this cutting-edge performance is backed by up to 150 hours of high-performance gameplay at 1000 Hz, giving gamers the endurance they need to stay ahead.
Debuting in the DeathAdder V4 Pro is Razer’s first Optical Scroll Wheel, purpose-built for esports. More precise and durable than traditional mechanical scroll wheels, it offers triple the durability and consistent, tactile control even under intense gameplay. The mouse also features the all-new Razer Optical Mouse Switches Gen-4, redesigned for a crisp, enhanced click feel and rated for an industry-leading 100 million clicks— delivering unmatched longevity and reliability.
At its core is the Razer Focus Pro 45K Optical Sensor Gen-2, offering flawless tracking across a wide range of surfaces. With up to 45,000 DPI, 900 IPS, and 85 G, it delivers 99.8% resolution accuracy. Advanced features like Dynamic Sensitivity, Mouse Rotation, and Sensitivity Matcher give players a decisive edge in high-stakes scenarios.
Ultra-Lightweight Ergonomics
Weighing just 56 grams (black) and 57 grams (white), the DeathAdder V4 Pro sets a new benchmark for ultra-lightweight gaming mice. Its iconic ergonomic shape—trusted by fans and pros alike—has been thoughtfully refined to enhance both performance and comfort. Larger PTFE feet ensure smoother gliding across surfaces, while split side buttons are designed to minimize accidental clicks during intense gameplay. A smooth touch finish not only improves grip but also adds a premium feel.
Constructed with over 67% of bio-based and post-consumer recycled plastics, the DeathAdder V4 Pro is designed with sustainability in mind. Razer has optimized the internal structure to maintain a light yet strong build. Reinforced side walls add durability without compromising weight, and the re-engineered chassis strikes the perfect balance between speed, control, and long-lasting comfort.
Designed with Esports Pros
The DeathAdder V4 Pro was developed with direct input from professional players, including Nikola “NiKo” Kovač, a Counter-Strike legend with 10 international championship titles and the newest member of Team Razer. Razer collaborated closely with NiKo to fine-tune elements of the mouse, from weight distribution to button feel and overall handling.
“The DeathAdder V4 Pro gives me the precise control I need in competitive matches," said NiKo. "I’ve been using early prototypes since January, including in official tournaments, and shared a lot of live feedback throughout the process. I also visited Razer’s HQ and development lab in Singapore, where I was able to speak directly with the engineers and help fine-tune the mouse for top-level performance."
“Every millisecond matters in esports, and the DeathAdder V4 Pro is built to deliver that competitive edge,” said Jeffrey Chau, Global Esports Director at Razer. “The DeathAdder V4 Pro is the result of years of collaboration with the world’s top players. It’s not just an upgrade—it’s a complete redefinition of what a high-performance ergonomic mouse can be.”
The DeathAdder V4 Pro highlights Razer’s commitment to advancing gaming technology through smart innovation and sustainable design. Built for competitive play, it blends performance-focused engineering with eco-conscious materials to support both gameplay and responsible production.
