The Razer Basilisk V4 Pro is the new flagship of a refreshed ergonomic mouse lineup that also includes a lighter HyperSpeed model and a redesigned charging dock. Razer has confirmed the specifications for both mice alongside the new Mouse Dock V2 Pro, giving fans of its signature thumb-rest shape a genuine generational upgrade rather than a cosmetic refresh.
Key takeaways
- ✓Razer Basilisk V4 Pro weighs 100g and adds a third side button plus an M1 edge button
- ✓The flagship uses a Focus Pro 50K Optical Sensor Gen-3 rated to 50,000DPI and 930IPS
- ✓Mouse Dock V2 Pro adds magnetic wireless charging and an 8000Hz wireless transceiver
- ✓Basilisk V4 HyperSpeed weighs 94g and runs a Focus X 33K sensor with up to 140 hours of battery life
- ✓Both mice support HyperSpeed Wireless Gen-2, Bluetooth 6.2 and wired connection modes
The announcement lands at a point when wireless gaming mice are converging on similar feature sets, from ultra-high polling rates to magnetic charging docks. Razer’s answer is to push its ergonomic Basilisk line further into premium territory, while still offering a cheaper, lighter alternative for players who do not need every feature.

What’s new on the Razer Basilisk V4 Pro
The Basilisk V4 Pro’s official product page confirms a 100g weight, which is notably light for a mouse with this much built-in control. Razer has added a third side button and a new M1 edge button, bringing the total to 14 customisable controls. The brand has also repositioned the multi-function trigger, a change aimed at players who rely on quick mode switches mid-match.
Underneath the shell sits Razer’s Focus Pro 50K Optical Sensor Gen-3, which tracks up to 50,000DPI with 930IPS of speed and 90G of acceleration headroom. That is a considerable jump over previous Basilisk sensors and puts the mouse on par with Razer’s most precision-focused releases. The switches have also been upgraded to Optical Mouse Switches Gen-4, rated for 100 million clicks, which should mean a longer usable life before the tell-tale double-click issues that plague ageing mechanical switches appear.
Scrolling gets its own overhaul through the HyperScroll Tilt Wheel Gen-2. It offers a 24-step tactile mode, a finer 48-step precision tactile mode, a free-spin mode for rapid scrolling, and a smart-reel mode that automatically swaps between tactile and free spin depending on how fast someone scrolls. It is a small detail, but one that matters for anyone who uses scroll-wheel weapon switching in shooters.
Basilisk V4 HyperSpeed trims weight and cost
Alongside the Pro model, Razer has introduced the 94g Basilisk V4 HyperSpeed as the more accessible option in the range. It swaps the flagship’s sensor for a Focus X 33K unit, which still comfortably covers the needs of most competitive players despite the lower ceiling compared with the Pro’s 50,000DPI sensor.
Battery life on the HyperSpeed model reaches up to 140 hours, a solid figure for a mouse in this class, even if it falls short of the Pro variant’s numbers. The trade-off is a simpler feature set and fewer customisable buttons, positioning it as the sensible pick for buyers who want Razer’s ergonomic shape and core wireless technology without paying for every extra.
| Feature | Basilisk V4 Pro | Basilisk V4 HyperSpeed |
|---|---|---|
| Weight | 100g | 94g |
| Sensor | Focus Pro 50K Optical Sensor Gen-3 | Focus X 33K |
| Max tracking speed | 930IPS, 90G acceleration | Not specified |
| Switches | Optical Mouse Switches Gen-4 (100 million clicks) | Not specified as Gen-4 |
| Battery life (max) | Up to 200 hours (1000Hz wireless), up to 275 hours (Bluetooth) | Up to 140 hours |
| Customisable controls | 14, including M1 edge button and third side button | Fewer, simplified layout |
Mouse Dock V2 Pro and connectivity options
Both mice connect through Razer’s HyperSpeed Wireless Gen-2 or Bluetooth 6.2, with a wired mode available as a third option. Razer says the Basilisk V4 Pro can switch between up to five devices, which suits anyone juggling a gaming PC, a laptop and a tablet. Battery life on the Pro climbs to roughly 200 hours at 1000Hz over wireless, or as much as 275 hours when running over Bluetooth with reduced polling demands.
The new Mouse Dock V2 Pro launches alongside the flagship and does double duty as a magnetic wireless charger and an integrated 8000Hz transceiver. That combination lets the Basilisk V4 Pro hit an 8000Hz polling rate while sitting in the dock rather than needing a separate USB dongle plugged directly into the PC, tidying up desk setups for players who care about cable clutter as much as raw performance.
Visually, the Basilisk V4 Pro carries a seven-zone Chroma RGB lighting layout with full underglow, keeping it consistent with the rest of Razer’s current ecosystem for anyone running synced lighting across a keyboard, headset and mouse pad.
How the Basilisk V4 Pro stacks up
Razer already fields several high-end wireless mice, including Razer’s Viper V4 Pro and the DeathAdder V4 Pro, both of which chase ultralight, symmetrical or classic palm-grip shapes for fast-paced shooters. The Basilisk line has always carved out a different niche, leaning into a pronounced thumb rest and a heavier button count aimed at players who want more programmable inputs within easy reach, rather than shaving every possible gram.
That distinction remains intact here. The 50,000DPI sensor and 8000Hz dock charging bring the Basilisk V4 Pro’s internals up to the same tier as Razer’s lighter flagships, while the extra buttons and tilt wheel modes keep its identity as the control-heavy option in the range. For buyers comparing ecosystems, it is also worth noting that rivals are moving in a similar direction, with Logitech’s own upcoming G Pro X3 Superstrike reportedly chasing comparable sensor and wireless upgrades.
For shoppers who like the Basilisk shape but do not need every feature, the HyperSpeed model and Razer’s existing Pro Click V2 remain reasonable alternatives, each trading some top-end specification for a lower barrier to entry. Both new Basilisk models are available now through Razer’s usual retail channels.
