The Razer Basilisk V4 Pro is the latest version of Razer’s ergonomic Basilisk gaming mouse. Razer announced the Basilisk V4 line on October 8 alongside the Mouse Dock V2 Pro wireless charging dock. Razer’s US store lists the V4 Pro from $169.99 and the cheaper Basilisk V4 HyperSpeed from $109.99.
The battery number needs a condition. Razer rates the V4 Pro at up to 275 hours on Bluetooth 6.2, but only up to 200 hours on its HyperSpeed Wireless Gen-2 link at 1,000 Hz. The release gives no battery rating for the 8,000 Hz polling the mouse also advertises.
What changes on the Basilisk V4 Pro
The shape and signature thumb rest stay. Razer moved the multi-function trigger for what it calls a more natural reach. The new body also makes room for a third side button and an M1 edge button. Together with the existing controls, that makes 14 customizable controls. Razer says the mouse still weighs 12 g less than its predecessor.
The scroll wheel is the headline change. The HyperScroll Tilt Wheel Gen-2 keeps the familiar 24-step tactile mode. A new Precision Tactile mode doubles that to 48 steps for hotbars and ability menus. Free-Spin handles long scrolls, and Smart-Reel switches between the two modes based on scroll speed. Razer also adds Virtual Acceleration in its Synapse software, with five levels.
The Basilisk has always been about giving players the freedom to play their way

Inside, the Focus Pro 50K Optical Sensor Gen-3 reaches up to 50,000 DPI, 930 IPS and 90 G of acceleration. HyperSpeed Wireless Gen-2 delivers true 8,000 Hz polling in both wireless and wired modes. Optical Mouse Switches Gen-4 are rated for 100 million clicks, with 12 percent lighter actuation. In addition, Perfect 180 turns the view half a circle on demand for low-sensitivity shooter players.
Battery life and the 275-hour claim
Razer’s release lists two battery figures for the V4 Pro. Up to 200 hours applies to HyperSpeed Wireless Gen-2 at 1,000 Hz, and up to 275 hours applies to Bluetooth 6.2. The 200-hour figure covers the HyperSpeed link, which is the connection that carries the 8,000 Hz polling.
Connectivity is flexible. The mouse supports up to five devices across HyperSpeed Wireless Gen-2, Bluetooth 6.2 with up to three paired devices, and wired mode. As a result, one mouse can move between a gaming PC, a laptop and a tablet at the touch of a button.
Mouse Dock V2 Pro and the cheaper V4 HyperSpeed
The Mouse Dock V2 Pro charges the mouse magnetically when you set it down. It has an integrated 8,000 Hz transceiver, so it also supports HyperSpeed Wireless Gen-2 performance. Razer says compatible Razer mice and keyboards can connect through the dock for a cleaner desk. It adds 8-zone Chroma underglow, a charge status indicator and an anti-slip base. Razer’s US store lists it from $69.99.
Wireless charging is not built in. Razer’s FAQ says buyers swap the mouse’s cover puck for the one that comes with the dock. The Basilisk V4 HyperSpeed works the same way. That model weighs 94 g and uses the Focus X 33K Optical Sensor Gen-3. It has 12 customizable controls and a 4-way tilt wheel with tactile and free-spin modes. Razer rates its battery at up to 140 hours on HyperSpeed Wireless, and its product page adds up to 225 hours on Bluetooth.
Pricing and where it fits
Razer’s US product page lists the V4 Pro from $169.99. When we checked on October 8, it also offered $25 in Razer Store Credit for launch-week orders. Prices are for the United States, and the release does not give pricing for other markets.
The mouse lands during a busy stretch for Razer. The company introduced the Tartarus V2 Pro keypad in September. Meanwhile, Logitech G’s PRO Series refresh also targets competitive players this fall.
