Mercury K1 75% Wireless Mechanical Gaming Keyboard

The GravaStar Mercury K1 is a 75% wireless mechanical gaming keyboard built around an aluminum alloy exoskeleton. It ships with custom GravaStar x Kailh Cheery Pink linear switches factory-lubed for a 40 gf actuation force, 1.5 mm pre-travel and 3.5 mm total travel. The compact 79-key layout plus a programmable control knob targets gamers and typists who want a smaller footprint without losing dedicated function rows.

Aluminum Exoskeleton Gasket Mount

A streamlined aluminum frame measuring 343 by 156 by 46 mm and weighing 1.06 kg wraps a gasket-mounted polycarbonate plate and five layers of sound-dampening foam for a low-pitched, cushioned bottom-out. PBT and PC keycaps resist shine over long sessions. Tri-mode connectivity covers wired USB-C, Bluetooth and 2.4 GHz wireless via the included Type-A receiver, while an 8000 mAh rechargeable battery powers dual independent RGB backlighting systems for extended cable-free use.

Hot-Swap Socket Switch Variety Pack In The Box

The hot-swap PCB accepts 3-pin and 5-pin switches without soldering, letting owners swap the pre-installed linear switches in seconds. The package includes a keycap and switch 2-in-1 puller, a cleaning brush, a cleaning cloth, a USB Type-A to Type-C cable, the 2.4 GHz receiver and four extra switches: one Kailh Platycodon, one Kailh Crackle Ice Box, one KTT Silent Blue and one KTT Baby White, so users can audition tactile, clicky or silent feel immediately.

The 2.4 GHz mode connects through the included Type-A receiver for low-latency gaming and typing without cables.

What are the exact dimensions and weight so I can check desk fit?

The keyboard measures 343 mm wide, 156 mm deep and 46 mm high, weighing 1.06 kg with its aluminum alloy frame.

How do I pair the keyboard in Bluetooth mode, and what step do people miss?

Hold the Bluetooth key until the indicator flashes, then select the keyboard in your OS Bluetooth menu; the step often missed is keeping the keyboard in pairing mode long enough for the device to detect it.
