Razer has set the price of the Basilisk V4 Pro gaming mouse at $169.99, a figure that reflects the addition of a dedicated artificial intelligence key and a longer battery life. The device launched today in black and white, marking the first major refresh to the Basilisk line since October 2024.
The mouse now offers 200 hours of battery life at 1,000 Hz over 2.4GHz wireless, up from 150 hours on the previous model. Battery duration drops to 54 hours when the polling rate is increased to 8,000 Hz. The device connects via 2.4GHz wireless, Bluetooth, or USB-C, and it weighs 3.53 ounces, which is 0.42 ounces lighter than the Basilisk V3 Pro 35K.
Two new buttons bring the total number of programmable inputs to 12. One button, located beside the left mouse click, switches profiles by default. A second button, positioned in the thumb cluster, opens Razer’s AI prompt tool. The hardware uses a Focus Pro 50K optical sensor capable of 50,000 DPI and 930 IPS, and it features fourth-generation switches rated for over 100 million clicks.
Sarah Jacobsson Purewal, a senior editor at Tom’s Hardware, found the new layout uncomfortable for users with medium-sized hands. The profile button sits at the front edge of the 5.02-inch device, making it difficult to reach. The addition of the AI button pushed the existing thumb buttons back, creating awkward spacing that affected comfort during testing.
The device includes a tilt wheel with two tactile modes and a free-spin setting. The free-spin mode was described as too sensitive and prone to backscrolling, while the tactile modes received positive feedback. The mouse tracks on most surfaces, including glass at least 4mm thick, and the switches produced no misclicks during review.
Razer sells the Basilisk V4 Pro alongside the Mouse Dock V2 Pro, which costs $69.99. The dock provides wireless charging and houses an 8,000 Hz receiver. The mouse package includes a USB-A dongle, an adapter, and a 6-foot braided cable, but it does not include the flexible HyperFlex cable or grip tape.
The company positions the new mouse between the DeathAdder V4 Pro and the Naga V3 Pro. It is designed for players who want more functionality than a minimal shooter mouse but do not require the extensive button count of a MMO-focused device.
