75% aluminium wireless keyboard

The GravaStar Mercury K1 Pro is a 75% layout gaming keyboard built around a lightweight aluminium alloy frame with a brushed Interstellar Silver finish. It connects through wired, Bluetooth and 2.4 GHz wireless modes and carries an 8000 mAh rechargeable battery. The streamlined 79-key arrangement plus a rotary knob suits gamers and typists who want a compact desk footprint without losing dedicated function keys.

Gasket mount with five foam layers under load

A gasket-mounted structure combined with five layers of foam dampening absorbs vibration during extended sessions, keeping the typing sound consistent when keys are held down in long combos. Custom Kailh Speedy Mint linear switches actuate at 45 gf with 1.2 mm pre-travel and 3.5 mm total travel, rated for 70 million keystrokes, so repeated actuation stays smooth without degradation. Dual independent RGB systems with 13 lighting modes and 16.8 million colours run from the large battery without noticeable dimming over hours of use.

Hot-swappable switches and included switch sampler

The PCB is hot-swappable, letting owners replace switches with a 2-in-1 puller without soldering; the box also supplies four extra switches — Kailh Platycodon, Kailh Crackle Ice Box, KTT Silent Blue and KTT Baby White — for immediate experimentation. Double-shot PBT pudding keycaps resist shine and allow south-facing RGB to shine through legends. The only common friction point is the initial 2.4 GHz receiver pairing on some Windows machines, which usually resolves after a firmware update via the wired connection.

Questions about this item

Does the 8000 mAh battery last through all-day sessions without overheating?

The 8000 mAh rechargeable battery powers the keyboard for extended use, and the aluminum alloy frame helps dissipate heat during long gaming or typing sessions.

Which ports or receivers do I need on my PC to use the tri-mode connection?

You need a free USB-A port for the included 2.4 GHz receiver and a USB-C port or USB-A port with the supplied cable for wired mode; Bluetooth is built in for wireless pairing.

Will the hot-swappable sockets accept the Cherry MX switches I already own?

Yes, the hot-swappable PCB is compatible with standard 3-pin and 5-pin MX-style switches, so your existing Cherry MX switches can be installed without soldering.
