Keychron G3 8K Wireless Gaming Mouse, 30,000 DPI, 47±3g

The Keychron G3 is a tri-mode gaming mouse for buyers who want a very light design, adjustable high polling and wireless or wired use. Its 8,000Hz polling claim is paired with an up-to-160-hour battery claim specifically for Bluetooth mode, so these headline figures describe different operating priorities.

What to know before buying

Listing details to confirm

The listing is inconsistent about kit contents: its explicit included-components list names adapters, a receiver and a cable but does not name the mouse, while promotional claims describe the mouse itself. Confirm the selected listing's package contents. The title also gives 160 hours without a mode, whereas detailed specifications limit that figure to Bluetooth mode. The 8,000Hz polling claim applies to 2.4GHz or wired use according to the listing, and DPI above 5,000 is configured through Keychron Launcher Web.

Customer feedback reports positive impressions of build quality, low weight and ergonomic feel, with a specific mention of a smooth scroll wheel. Those perceptions align with the listed lightweight, contoured design, but feedback does not establish performance or fit for every hand. The rating distribution is largely five-star, with a smaller share of lower ratings and no supplied explanation for those ratings.

Frequently asked questions

Does the G3 support 8,000Hz polling in every mode?

The listing specifies 8,000Hz in 2.4GHz or wired mode. It does not state that this rate is available over Bluetooth.

Is the 160-hour battery claim valid for all connection modes?

No. Detailed specifications state up to 160 hours in Bluetooth mode. The title omits that condition, so do not treat it as a universal runtime.

Can I customise the buttons and save settings on the mouse?

The listing describes five programmable buttons and up to five on-board profiles. It says Keychron Launcher Web is used for remapping and configuration.

What is included in the package?

The explicit contents list names an extension adapter, Type-A receiver, Type-A to Type-C adapter and Type-C cable. It does not name the mouse, so confirm the selected listing's kit contents.
