Razer Viper V4 Pro Gaming Mouse: Ultralight wireless control for esports

If you are still using a heavy wired mouse, the shift to Razer Viper V4 Pro Gaming Mouse brings an ultralight 49 g feel that favours faster flicks and steadier aim. High 8000Hz polling and the Focus Pro 50K sensor ensure consistent cursor movement during rapid sequences.

⚡ At a Glance

• Tracking Precision: Focus Pro 50K sensor with up to 50,000 DPI, 930 IPS and 90G acceleration for accurate, low-jitter cursor movement
• Perfect for: Competitive esports players and FPS gamers who prioritise minimal weight and ultra-low latency
• Not intended for: LAN tournaments or organisers that require wired-only peripherals; wireless-first operation will prevent compliance and could force last-minute equipment swaps

Ultralight 49 g wireless mouse with HyperSpeed Wireless Gen-2, 8000Hz polling and up to 180 hours battery life. Optical Gen-4 switches rated for 100 million clicks and 100% PTFE feet complete the hardware set.

📋 Technical Details at a Glance

Weight: 49 g (roughly the weight of a KitKat chocolate bar)
Polling rate: 8000 Hz
Sensor DPI: Up to 50,000 DPI
Tracking speed: 930 IPS
Acceleration: 90 G

How 49 g weight Changes aiming and fatigue

Ultra-light 49 g weight reduces the inertia you must overcome for each flick, so micro-adjustments feel faster and less effortful. During marathon sessions, the low mass cuts wrist strain and keeps small corrective movements more consistent.

Faster target acquisition and reduced forearm tiredness improve late-session performance. If you prefer heavier mice for anchored tracking, the lightness will feel less stable and may require an adjustment period.

Unlocking long sessions with up to 180-hour battery life

Delivers up to 180 hours between charges by combining HyperSpeed Wireless Gen-2 efficiency with an energy-lean sensor. On systems using the maximum 8000Hz polling rate battery consumption will rise, trading runtime for absolute responsiveness.

Extended runtime removes frequent charging interruptions during long practice blocks or streamed sessions. Battery life is generous, but enabling ultra-high polling modes will reduce the hours you get per charge.

Focus Pro 50K Sensor: Under the Hood

With up to 50,000 DPI, 930 IPS tracking and 90G acceleration, the Focus Pro 50K sensor captures rapid flicks and fine aiming motions with minimal smoothing. Frame Sync aligns transmissions to inputs and optical Gen-4 switches register clicks with near-instant actuation.

Pinpoint cursor control translates into steadier aim in fast-paced play and reliable registration under pressure. Extreme DPI settings exceed most displays' usable range, so most users will find lower, tuned settings deliver the best real-world accuracy.
