Manufacturer description

The Keychron K2 Version 2 packs a full 84-key layout into a 75% footprint, so you keep the arrow keys and function row that most tenkeyless boards drop. The aluminum frame gives the deck real weight on a desk, and Gateron G Pro Brown switches deliver a soft tactile bump rated for 50 million keystrokes. You can pair the K2 with up to three devices over Bluetooth 5.1 using a Broadcom chipset and swap between your laptop, phone, and iPad without re-pairing, or plug in over USB Type-C when you want N-key rollover for gaming (wireless mode drops to 6KRO). A 4000 mAh battery is among the largest…
