Manufacturer description
The GravaStar Mercury K1 is a 75% wireless mechanical keyboard that pairs an aluminum alloy chassis with a hollowed, sci-fi cutout frame, so it reads as a desk centerpiece rather than another black slab. Its 79-key layout keeps arrow keys and adds a rotary knob for volume, freeing desk width for low-sense mouse swings. Typing runs on GravaStar Stellar Bloom linear switches rated at 40gf actuation, 1.5mm pre-travel, and 3.5mm total travel, and the gasket mount plus five layers of sound-dampening foam tune the acoustics toward a deep thock instead of hollow clack. PBT and PC transparent…
SpecPicks Verdict
SpecPicks scored GravaStar Mercury K1 75% Wireless Gaming Keyboard using a rating × review-volume × price-fit model applied to published specs and reviews across the gaming peripherals category. GravaStar's gaming peripherals lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions
Is the GravaStar Mercury K1 hot-swappable?
Yes. The Mercury K1 accepts both 3-pin and 5-pin mechanical switches without soldering, and the horizontal slot positioning plate supports dual gasket and top mount structures for tuning feel and sound.
How does the Mercury K1 connect to my PC and other devices?
It is tri-mode: USB wired, Bluetooth 5.0, and 2.4GHz wireless. That lets you keep a desktop on the 2.4GHz dongle and a laptop or tablet paired over Bluetooth, switching between them.
What switches does it ship with and how do they feel?
It ships with GravaStar Stellar Bloom linear switches: 40gf actuation force, 1.5mm pre-travel, and 3.5mm total travel. Linear means smooth top-to-bottom travel with no tactile bump.
How big is the battery?
The Mercury K1 uses an 8000mAh rechargeable battery. GravaStar does not publish a runtime figure in this listing, and actual hours depend heavily on RGB brightness and connection mode, so check the product page for current claims.
Is a 75% keyboard with 79 keys enough for gaming and work?
The 75% layout keeps dedicated arrow keys and a function row while cutting the numpad, so it covers gaming and general typing. If you enter numbers all day, you would need a separate numpad.
