Razer has launched the Basilisk V4 Pro, a $169.99 wireless gaming mouse built around extensive customization rather than the ultralight design trend. It is available now in black and white, alongside a $109.99 Basilisk V4 HyperSpeed and a $69.99 Mouse Dock V2 Pro.
The headline specifications are a 50,000-DPI optical sensor, true 8,000 Hz polling in wired and 2.4 GHz wireless modes, 14 customizable controls and a redesigned four-way tilt wheel. Razer also advertises up to 275 hours of battery life, although that maximum applies to Bluetooth—not the faster connection most competitive players will use.
What changed on the Basilisk V4 Pro
The new model keeps the Basilisk family’s right-handed ergonomic shape and thumb rest. Razer added a third side button and an M1 edge button while moving the multi-function trigger to make it easier to reach. Together, the mouse offers 14 customizable controls through Razer Synapse.
Those controls can handle ordinary button assignments, macros and Razer HyperShift secondary functions. Razer also includes a configurable “Perfect 180” action intended to turn a player’s view by 180 degrees in supported first-person games. Its effectiveness depends on the game’s sensitivity and the settings configured in Synapse.
One side button is mapped to Razer’s AI Prompt Master by default. This opens an AI assistant for tasks such as rewriting or summarizing text. The assignment is optional and can be replaced with another command. That matters because the feature may be irrelevant—or distracting—for buyers who only want gaming controls.
The scroll wheel has four useful behaviors
The HyperScroll Tilt Wheel Gen-2 is more than a standard clickable wheel. Its normal tactile mode has 24 steps, while a new Precision Tactile mode doubles that to 48 steps for finer navigation through weapon lists, hotbars or long timelines. Free-Spin mode removes the resistance for fast scrolling, and Smart-Reel can automatically move between tactile and free-spinning behavior based on how quickly the wheel is turned.
The wheel also tilts left and right, and those actions can be remapped. This makes the V4 Pro potentially useful outside games for spreadsheets, video-editing timelines and other applications that benefit from horizontal scrolling.
50K sensor and 8,000 Hz wireless polling
Razer’s Focus Pro 50K Optical Sensor Gen-3 is rated for up to 50,000 DPI, 930 inches per second and 90 G of acceleration. Those maximums are far beyond what most people will use, but the sensor also supports one-DPI adjustments, separate lift-off and landing distances, surface calibration and sensitivity matching.
The mouse can report its position at up to 8,000 Hz in wired mode or through Razer HyperSpeed Wireless Gen-2. A higher polling rate can reduce the delay between movement and an updated cursor position, particularly on high-refresh-rate displays. It also increases power use and processing overhead, so 1,000 Hz remains the more practical setting for everyday work and many games.
Fourth-generation optical switches are rated by Razer for more than 100 million clicks. This is a manufacturer durability claim, not an independent longevity guarantee. The mouse weighs about 100 grams, making it lighter than its predecessor but still much heavier than the 50-to-70-gram mice commonly marketed for esports.
The 275-hour battery claim needs context
Razer rates the Basilisk V4 Pro for up to 275 hours over Bluetooth 6.2. The company’s more relevant figure for gaming is up to 200 hours over HyperSpeed Wireless Gen-2 at 1,000 Hz. Razer does not present the 275-hour number as an 8,000 Hz result, so shoppers should not expect maximum polling and maximum endurance at the same time.
The mouse can pair with up to three Bluetooth devices, one HyperSpeed connection and a wired USB connection. Users can therefore move it among a desktop, laptop and tablet without repeatedly pairing it.
Wireless charging costs extra
The $69.99 Mouse Dock V2 Pro adds magnetic charging, an integrated 8,000 Hz wireless transceiver and eight-zone Chroma RGB lighting. The mouse’s cover puck must be replaced with the charging puck supplied with the dock. Razer’s FAQ lists the new dock and its HyperFlux V2 system as the compatible wireless-charging options, so a typical Qi phone charger is not a substitute.
The V4 Pro itself has seven zones of Chroma RGB underglow. Lighting can react to supported games, but it will also affect battery life. Buyers focused on endurance can reduce or disable the lighting in Synapse.
The cheaper Basilisk V4 HyperSpeed is worth comparing
The $109.99 Basilisk V4 HyperSpeed retains the right-handed shape but steps down to a 33,000-DPI sensor, 12 customizable controls and a simpler four-way tilt wheel. Razer rates it for up to 140 hours through HyperSpeed Wireless or 225 hours through Bluetooth. It can reach 8,000 Hz only with an optional compatible dock or HyperPolling accessory.
That $60 difference makes the cheaper model attractive to buyers who do not need the Pro’s extra controls, higher-spec sensor or native 8,000 Hz receiver. The Pro is better suited to players who want its additional inputs, refined wheel and multi-device flexibility.
Who should consider it
The Basilisk V4 Pro is aimed at right-handed gamers who prefer comfort, abundant controls and a versatile scroll wheel over the lowest possible weight. It may also appeal to people who use one mouse for both gaming and productivity.
Left-handed users should look elsewhere because the shell and thumb controls are strongly asymmetrical. Existing Basilisk V3 Pro owners should also compare carefully: the V4 Pro improves the sensor, button layout, polling rate and battery claim, but it does not reinvent the basic design.
Razer’s official Basilisk V4 Pro product page lists the detailed features and compatibility information. Same-day coverage from Engadget confirms the lineup and prices, while Windows Central’s review provides early hands-on context about ergonomics, charging and the default AI control.
