Razer DeathAdder V4 Pro Wireless Gaming Mouse, 8K Polling Rate, 56g, Black

Competitive players who prioritize speed and hand comfort will find a lot to like in the Razer DeathAdder V4 Pro. Built as a wireless gaming mouse for fast-paced titles like first-person shooters and MOBAs, it brings an ultra-lightweight 56-gram build together with a re-engineered ergonomic shape. Shaving weight down to this level allows your wrist and arm to make quick, reactive swipes across your desk without feeling weighed down during long tournaments or competitive matches.

Sensor performance is centered around the Focus Pro Optical Sensor Gen-2, which delivers up to 45K DPI, 900 IPS tracking speed, and 99.8 percent tracking accuracy. In practical terms, this high-precision sensor ensures that even your most aggressive movements translate directly onto the screen without skipping or drifting, regardless of the desk surface you use. Paired with Razer HyperSpeed Wireless Gen-2 technology, the connection stays stable and responsive while delivering polling rates of up to 8000 Hz.

Physical inputs on this model rely on optical components rather than standard mechanical contacts. Both the optical scroll wheel and the Gen-4 optical switches are engineered for tactile feedback while eliminating traditional debounce delays. The primary switches are rated for up to 100 million clicks, giving you long-term durability through demanding gaming habits. For power, you get up to 150 hours of battery life when running at standard 1000 Hz, and you can switch to a USB-C wired connection whenever you need to charge without losing access to the 8000 Hz polling performance.

There are practical trade-offs to keep in mind with such a specialized peripheral. While reaching an 8000 Hz polling rate delivers rapid responsiveness, running at maximum polling will drain the battery significantly faster than the quoted 150 hours, which is measured specifically at 1000 Hz. Additionally, tailoring features like Smart Tracking, Dynamic Sensitivity, and lift-off distance relies on installing and configuring Razer Synapse on your computer.

Verdict: The DeathAdder V4 Pro is an outstanding choice for tournament competitors and shooter fans who want an ultra-lightweight wireless gaming mouse with top-tier sensor specs and dual-connection flexibility. If you prefer a heavier peripheral or do not care about fast polling rates and software tuning, a simpler everyday mouse might suit you better.

• Weight: 56g
• Max DPI: 45,000 (Focus Pro Optical Sensor Gen-2)
• Max Speed: 900 IPS
• Sensor Accuracy: 99.8%
• Switch Rating: Gen-4 optical switches, 100 million clicks
• Max Polling Rate: Up to 8000 Hz (wired and wireless)
• Battery Life: Up to 150 hours at 1000 Hz
• Connectivity: Razer HyperSpeed Wireless Gen-2, USB-C wired
• Color: Black

A great fit if you:

• Compete in fast-paced first-person shooters or MOBAs where ultra-fast tracking and lightweight 56-gram handling provide a distinct competitive advantage.
• Want high-end responsiveness and plan to take full advantage of an 8000 Hz polling rate over wireless or wired play.
• Need long battery endurance that lasts through multiple days of practice, offering up to 150 hours when set to 1000 Hz.
• Value switch longevity and prefer the tactile feedback and 100-million click lifespan of Gen-4 optical switches.

Consider something else if you:

• Prefer a heavier peripheral with adjustable physical weights rather than a stripped-down, lightweight tournament chassis.
• Want a basic plug-and-play mouse without the need for companion software to configure tracking distances and sensor profiles.

Confirm on the listing:

• Check whether the USB-C charging cable and wireless receiver adapter are bundled directly in the box.
• Confirm that your operating system supports the Razer Synapse software needed to adjust DPI steps and lift-off distance.
• Review the physical dimensions to ensure the re-engineered ergonomic profile matches your preferred grip style.

How to compare your options: When shopping for an esports-focused mouse, focus primarily on weight, sensor tracking fidelity, and connectivity options. This model stands out by combining an ultra-low 56-gram weight with an 8000 Hz polling rate and a 45K DPI optical sensor that tracks up to 900 IPS. If you prioritize maximum wireless battery life, note how polling rates affect longevity, as the advertised 150 hours applies specifically when operating at 1000 Hz.

• Install Razer Synapse upon unboxing to dial in your DPI levels, adjust your lift-off distance, and enable Smart Tracking for your mouse surface.
• Set the polling rate to 1000 Hz during casual gameplay or work to reach up to 150 hours of battery life, switching to 8000 Hz when stepping into high-stakes matches.
• Plug in the USB-C cable whenever you need to recharge, allowing you to keep playing with full 8000 Hz responsiveness without downtime.
• Keep the optical sensor on the underside clean and free of dust by wiping it gently with a dry, lint-free cloth as recommended for sensitive optical lenses.

Can I use this mouse while it is charging?
Yes. The mouse supports dual wireless and USB-C wired modes, allowing you to plug it directly into your setup and continue playing at up to an 8000 Hz polling rate.

How long does the battery last on a single charge?
The battery lasts up to 150 hours when operating at a 1000 Hz polling rate. Higher polling rates, such as 8000 Hz, will reduce battery runtime between charges.

What kind of switches does this mouse use?
It features Gen-4 optical switches alongside an optical scroll wheel. These switches provide tactile feedback and are rated for up to 100 million clicks.

Can I adjust the sensor sensitivity and lift-off distance?
Yes. You can customize the DPI, polling rate, lift-off distance, and features like Smart Tracking and Dynamic Sensitivity through the Razer Synapse software.

What is the maximum tracking speed of the sensor?
The 45K DPI Focus Pro Optical Sensor Gen-2 is rated for tracking speeds of up to 900 IPS with 99.8 percent accuracy across compatible surfaces.
