Razer Launches Basilisk V4 Mouse and Dock V2 Pro with Enhanced Sensors

Battery life extends to 275 hours on Bluetooth alone
The Basilisk V4 offers dramatically extended wireless runtime compared to typical gaming mice.

So these are new products, but the source keeps saying they're "incremental" upgrades. What actually changed from the last version?

Mimi

The scroll wheel got a real overhaul—multiple modes now instead of one. The sensor is faster and more precise. Battery life jumped significantly. But the overall shape and design stayed the same.

Luke

Right, and we should be clear: we don't know how the V3 compared to the V4 in real-world gaming. The specs are there, but there's no independent testing mentioned. We're taking Razer's word that these are improvements.

Mark

Fair. What about the dock? Is that new technology or just a new version of an existing product?

Mimi

It's a new version. The key addition is the 8,000 Hz transceiver built in, which means you get the same wireless performance whether you're using the dock or not. Before, you might have needed separate hardware.

Luke

Again, though—we don't have details on what changed from V1 to V2. The source just says it's an improvement. We know the price ($70) and what it does, but not what was different before.

Mark

Does the dock work with any Razer mouse, or just the Basilisk V4?

Mimi

The source says "compatible Razer mice and keyboards," so it's not exclusive to the V4. But it doesn't specify which models are compatible.

Luke

That's an important gap. A reader might buy the dock and find out their existing mouse doesn't work with it. That should have been clearer in the announcement.

  • Competitive gamers demand ever-finer margins, and Razer answers with a 50,000 DPI sensor and 8,000 Hz wireless polling — numbers that would have seemed fantastical just a few years ago.
  • The scroll wheel alone receives four distinct operating modes, signaling how even the smallest physical gesture is now subject to granular optimization.
  • Battery anxiety — a persistent friction in wireless gaming — is addressed head-on with up to 275 hours of life on Bluetooth 6.2, and a magnetic dock that charges the moment the mouse is set down.
  • Fourteen customizable controls, automatic profile switching, and multi-device connectivity across five connection types collapse the gap between a gamer's setup and their moment-to-moment needs.
  • The ecosystem play is deliberate: dock, mouse, keyboard, and over 50 partner products synchronize through Chroma RGB and HyperSpeed, turning a desk into a unified, responsive environment.

In the ongoing human pursuit of precision and control, Razer has refined two familiar tools — the Basilisk V4 Mouse and Dock V2 Pro — not by reimagining them, but by deepening what they already do well. Released in October 2026 at $170 and $70 respectively, these peripherals speak to a particular kind of player: one for whom the distance between intention and action must be as small as technology allows. It is a quiet story of incremental mastery, where milliseconds and millimeters carry genuine meaning.

Razer this week quietly expanded its peripheral lineup with the Basilisk V4 Mouse and Dock V2 Pro — not as dramatic reinventions, but as careful evolutions of hardware that already had a loyal following. The $170 mouse and $70 dock arrive with a clear message: more control, less friction, longer endurance.

The Basilisk V4 builds on its predecessor's multi-function trigger by adding a third side button and a new edge-mounted M1 button, bringing total customizable controls to 14. Through Razer Synapse, each can be mapped to macros or secondary Hypershift functions, with smart profiles that automatically switch the moment a linked game launches. The scroll wheel sees the most tangible redesign, now offering four modes — standard 24-step tactile, a finer 48-step Precision Tactile for ability cycling, a free-spinning mode for rapid scrolling, and a Smart-Reel that transitions between them automatically based on speed.

At the core is the Focus Pro 50K Optical Sensor Gen-3, capable of 50,000 DPI, 930 inches per second tracking, and 90 G acceleration. Frame Sync aligns the sensor's scanning to the polling cycle, trimming latency while preserving battery. HyperSpeed Wireless Gen-2 delivers a true 8,000 Hz polling rate wirelessly — a threshold once reserved for wired connections. Asymmetric Cut-Off lets players independently tune lift-off and landing distances for more consistent aim resets.

Battery life reaches 200 hours over HyperSpeed at 1,000 Hz, and stretches to 275 hours on the newly upgraded Bluetooth 6.2. The mouse connects across five modes — wired, two wireless frequencies, and up to three Bluetooth devices — making it equally at home on a gaming rig, a laptop, or a tablet. Seven zones of Chroma RGB with full underglow round out the package, reactive across more than 300 integrated games.

The Dock V2 Pro completes the picture with magnetic wireless charging — place the mouse down, pick it up ready. The dock houses an 8,000 Hz transceiver, supports multi-device connectivity for mice and keyboards alike, and adds its own eight-zone Chroma underglow. For those who prefer an alternative, Razer's HyperFlux V2 offers a second charging path, giving players flexibility in how they organize their space.

Razer this week introduced two new pieces of gaming hardware: the Basilisk V4 Mouse, priced at $170, and the Dock V2 Pro, selling for $70. Both represent incremental refinements to their predecessors rather than fundamental redesigns. The focus is on performance gains and added customization rather than visual overhaul.

The Basilisk V4 carries forward the multi-function trigger that defined earlier versions, now joined by a third side button and a new M1 edge button along the mouse's edge. This brings the total customizable controls to 14. Users can map any of these buttons to Razer Hypershift to access secondary functions, while the Razer Synapse software allows macros and smart profiles that automatically switch layouts the moment a linked game launches. The scroll wheel receives the most visible upgrade: the new HyperScroll Tilt Wheel Gen-2 operates in multiple modes. Tactile mode delivers the traditional 24-step scrolling, while a new Precision Tactile mode offers finer 48-step control for cycling through hotbars and abilities. Free-Spin mode enables fast, smooth scrolling for longer distances, and Smart-Reel automatically switches between tactile and free-spin based on scroll speed. Virtual Acceleration, tunable in Synapse, dynamically increases scroll speed as the user scrolls faster, with five acceleration levels available.

The sensor upgrade sits at the heart of the performance story. The Focus Pro 50K Optical Sensor Gen-3 delivers up to 50,000 DPI, 930 inches per second tracking speed, and 90 G acceleration. Frame Sync technology aligns sensor scanning to the mouse's polling cycle, reducing motion latency and improving battery efficiency. Razer HyperSpeed Wireless Gen-2 supports a true 8,000 Hz polling rate in both wireless and wired modes. Asymmetric Cut-Off gives players independent control over lift-off and landing distance, allowing fine-tuning of tracking behavior for cleaner resets and more consistent aim.

Battery life extends significantly. On HyperSpeed Wireless Gen-2 at 1,000 Hz, the mouse runs for up to 200 hours. Switching to Bluetooth 6.2 pushes that to 275 hours. The mouse supports five-way multi-device connectivity: HyperSpeed Wireless Gen-2, the newly upgraded Bluetooth 6.2 with up to three paired devices, and wired mode. This allows seamless movement between a gaming rig, laptop, and tablet at the touch of a button. The lighting system features seven zones of Razer Chroma RGB with full underglow, projecting light downward and outward to remain visible regardless of grip style. Each zone customizes across 16.8 million colors and reacts dynamically across more than 300 Chroma-integrated games, while syncing with compatible Razer devices and over 50 partner products.

The Dock V2 Pro complements the mouse with magnetic wireless charging. Users simply place the mouse on the dock to charge and pick it up ready to use. The dock integrates an 8,000 Hz transceiver that enables Razer HyperSpeed Wireless Gen-2 performance. Razer HyperSpeed Multi-Device Support allows compatible Razer mice and keyboards to connect through the dock, creating a cleaner desk setup. The dock includes eight-zone Chroma RGB underglow, a charge status indicator, and an anti-slip base to keep it anchored. Razer also offers the HyperFlux V2 as an alternative wireless charging solution, giving gamers flexibility in choosing the charging method that fits their needs and desk arrangement.

Map any button to Razer Hypershift to unlock secondary functions, while macros and smart profiles in Razer Synapse switch layouts automatically the moment a linked game launches.
