This article covers 「国内正規品」Keychron G3 ウルトラライトマウス カーボンファイバー 44g 8000Hz トライモード ブラック.

Overview

The Keychron G3 is Keychron's take on the ultralight gaming mouse, pairing a 44g carbon-fiber shell with a flagship PixArt 3950 sensor. Built for fast-paced shooters and precision work alike, it supports tri-mode connectivity: 2.4GHz wireless, Bluetooth 5.3, and a wired USB connection. In 2.4GHz mode, the polling rate scales up to 8000Hz with six selectable steps from 125Hz to 8000Hz.
A 500mAh battery drives up to 37 hours at 8K polling, or about 140 hours at 1K, and Bluetooth mode extends that to roughly 160 hours. The symmetrical shape and matte gray finish keep the mouse neutral for both right- and left-handed users, while PTFE feet and a lightweight low-resistance cable support mixed wired and wireless workflows.

Connectivity & Compatibility

The G3 connects through a 2.4GHz USB receiver, Bluetooth 5.3, or a wired USB cable, making it easy to switch between a desktop, notebook, or even a tablet. Polling rate is adjustable in 2.4GHz mode across 125, 500, 1000, 2000, 4000, and 8000Hz, so you can trade response time for battery life depending on the scenario.
Customization runs through the browser-based Keychron Launcher. You can remap buttons, create macros, adjust DPI, set lift-off distance, and manage onboard profiles without installing a resident app. Settings are saved to the mouse's five onboard memory profiles, which means your configuration follows you when you plug the G3 into another PC.

Product Info

The Keychron G3 sits in the mid-to-high tier of gaming mice, competing on weight, wireless latency, and sensor performance rather than gimmicks. Its main differentiator is the combination of a carbon-fiber shell, a PixArt 3950 sensor, and 8K wireless polling in a product priced around ￥51,315 at the time of writing in Japan.
Bundled content includes the 2.4GHz receiver, a USB charging/data cable, and pre-installed PTFE feet. The mouse itself carries a 500mAh battery and five programmable buttons. For warranty terms, check Keychron's official support documentation, as coverage can vary by region.

Best Use Cases

Competitive FPS and arena shooters are the obvious home for the G3. At 44g, wrist and fingertip flicks feel light and quick, while the 8000Hz polling option helps reduce input lag during rapid aim corrections. Players who prefer a heavier, more stabilized mouse may find it too feathery, though.
A second sweet spot is mixed-device setups. If you use a work notebook for Bluetooth and a desktop for 2.4GHz gaming, the G3 can switch between them without re-pairing. Wired mode is also there for charging or low-latency sessions when the battery runs low.
Finally, it suits users who like deep customization. The browser-based Launcher and five onboard profiles cover DPI, LOD, macros, and button mapping without extra software living in your system tray. That said, if you rarely change settings and only need a basic office pointer, the premium sensor and low weight are more than you'd typically need.
