Manufacturer description

The GravaStar Mercury K1 is a 75% wireless mechanical gaming keyboard built around an aluminum alloy exoskeleton in Ice Blue, with 79 keys in a compact layout that frees up desk space for mouse sweeps without dropping the function row. Inside, GravaStar x Kailh linear switches hit a 40g actuation force with 1.5mm pre-travel, so inputs register early in the keystroke during fast-paced play.

Frequently Asked Questions

How many keys does the Mercury K1 have?

79 keys in a 75% layout. You keep the function row and arrow keys but lose the dedicated number pad, which shortens the board and leaves more room for mouse movement.

Can I use it with a Mac?

Yes. The Mercury K1 is listed as compatible with both Windows and Mac, and connects over 2.4GHz wireless, Bluetooth 5.0, or wired USB-C.

What switches does it use, and can I swap them?

It ships with GravaStar x Kailh linear switches rated at 40g actuation with 1.5mm pre-travel, and the board is hot-swappable, so you can change switches without soldering.

How long does the battery last?

GravaStar lists an 8000mAh battery, which is large for a 75% wireless board. Actual runtime depends on RGB brightness and connection mode; check the product listing for the manufacturer's current battery-life figures.

Is it loud, or does it sound muted?

It is built for a deep, damped sound. A gasket-mounted PC plate and 5-layer dampening absorb 87% of impact vibration, producing the low acoustic profile GravaStar calls "blue thunder" rather than a sharp, hollow click.
