GravaStar K1 Pro Interstellar Silver

The GravaStar K1 Pro Interstellar Silver is a compact gaming keyboard with a 75 per cent layout and 79 keys. Its aluminium alloy frame houses pudding PBT keycaps produced with dye sublimation printing. GravaStar x Kailh Speedy Mint linear switches provide 45gf actuation force, 1.2mm pre-travel and 3.5mm total travel. An 8000mAh rechargeable battery powers the unit.

Gamers wanting wireless freedom and a metal build

The tri-mode connection covers wired, wireless and Bluetooth use, while the gasket-mounted design with five-layer foam dampening reduces typing noise. Dual independent RGB backlight systems add per-key illumination and a separate knob ring light. Buyers who prefer tactile or clicky switches, or who require a dedicated numpad, will not find those features here.

79-key 75 per cent layout with knob

The streamlined layout fits 79 keys plus a multifunction knob into a smaller footprint than a full-size board. This single specification decides whether the keyboard matches the user's desk space and muscle memory.

Questions about this item

Will the 75% layout with 79 keys fit comfortably alongside my existing full-size keyboard on a standard desk?

The streamlined 75% layout keeps the function row and arrows while dropping the numeric pad, so it uses noticeably less width than a full-size board and leaves more mouse space.

How can I confirm the dual independent RGB backlight systems are working correctly after I connect the keyboard?

Both lighting systems should illuminate immediately on power-up; use the dedicated knob to cycle through brightness levels and effect modes to verify each zone responds independently.

What comes in the box with the GravaStar K1 Pro Interstellar Silver and what must I purchase separately?

The keyboard with pre-installed GravaStar x Kailh Speedy Mint linear switches and pudding PBT keycaps is included; a USB cable for wired or charging use is typically bundled, while switch pullers or extra keycaps are sold separately.
