Razer DeathAdder V4 Pro Ultra-Lightweight Wireless Ergonomic Gaming Mouse in Black - RZ01-05330100-R3U1

Razer RZ01-05330100-R3U1 DeathAdder V4 Pro Ultra-Lightweight Wireless Ergonomic Gaming Mouse in Black

The black Razer DeathAdder V4 Pro (RZ01-05330100-R3U1) is an ultra-lightweight wireless ergonomic mouse crafted for competitive PC gaming and esports. It brings the familiar right-handed DeathAdder shape into its most advanced generation, combining more than two decades of engineering refinement with insights from professional players. At 56 g, the Black edition is more than 10% lighter than its predecessor, helping palm- and claw-grip players make faster swipes with effortless control. A smooth-touch coating feels soft while remaining easy to grip, and a re-engineered internal structure with reinforced side walls maintains strength at low weight.

Razer HyperSpeed Wireless Gen-2 gives serious competitors an ultra-stable connection designed for speed and reliability. Under standard test conditions, the system is over 63% more efficient and delivers 37% lower latency than the previous generation.¹ True 8000 Hz polling is available in both wireless and wired modes, letting every movement and click reach the PC with an interval as low as 0.125 ms. An upgraded battery is built to power demanding scrims and tournament schedules, while the included USB Type A to USB Type C cable provides a direct wired option whenever it is needed.

Accuracy starts with a fully optical input system that unites the Razer Focus Pro 45K Optical Sensor Gen-2, an optical scroll wheel and Optical Mouse Switches Gen-4. Together, these technologies deliver the consistency, tactile feedback and responsive control required for high-precision play. Razer Synapse 4 adds extensive calibration tools for sensitivity, orientation, tracking and lift-off behavior, so players can tune the mouse around their own mechanics and preferred surface. Programmable controls handle essential commands or complex macros, Razer Hypershift opens an additional layer of custom keybinds and DPI control, and enlarged 100% PTFE feet help the mouse glide smoothly through rapid adjustments.

Key Features

Hemispherical Dongle Redesign

The larger wireless dongle houses a longer antenna for stronger signal reception, while a weighted base helps keep it anchored on the desk. Three configurable LED indicators provide at-a-glance information for connection quality, mouse battery status and the active polling rate.

Razer Optical Scroll Wheel

Razer's first optical scroll wheel for esports mice replaces a mechanical design with pro-grade tracking and defined tactile feedback. Engineered to be 3.3 times more reliable than mechanical variants, it brings greater precision and durability to high-pressure play.

Razer Focus Pro 45K Optical Sensor Gen-2

The improved sensor reaches up to 45,000 DPI, 900 IPS and 85 G while delivering 99.8% resolution accuracy. Surface-aware tracking and extensive sensitivity controls help maintain dependable aim across a variety of playing surfaces.

Razer Optical Mouse Switches Gen-4

Completely redesigned switches sharpen the click feel for crisp, responsive input. Their optical construction is rated for a 100-million-click lifecycle to support long-term competitive use.

Advanced Software Customization

Dynamic Sensitivity shapes DPI output and mouse input around an individual playstyle, while the Rotation Tool adjusts orientation for horizontal swipes. Single-DPI increments and Sensitivity Matcher make it easier to establish or transfer a preferred sensitivity.

Motion Sync aligns mouse signals with PC intervals, Smart Tracking maintains consistent lift-off distance across surfaces, and Asymmetric Cut-Off offers separate lift-off and landing distances across as many as 26 levels.³

Smart Polling Rate Switcher

Assign polling rates to favorite games in Razer Synapse, then let the software change the mouse's polling rate automatically according to the title being played. This keeps performance tailored to each game without repeated manual adjustments.

Footnotes:

¹ HyperSpeed efficiency and latency comparisons are under standard test conditions.

² The current up-to-150-hour battery figure requires the latest firmware and improves on the 120 hours stated on initial packaging.

³ Setting lift-off and landing distances too low may cause compatibility issues with the playing surface.

Safety warning: Do not look directly at the tracking beam or point it into anyone's eye. The beam is invisible to the naked eye and always on.

Operating notice: Keep the mouse away from liquid, humidity and moisture. Operate it from 0 degrees C / 32 degrees F to 40 degrees C / 104 degrees F.
