This keyboard is based on the K2 and features a number pad in an incredibly compact and unique 96% layout. The K4 is ideal for power users who need to perform well at home, on the go, or in the office, offering broad wireless compatibility for PC, Mac, Linux, and Android devices. The K4 comes with Gateron switches, which are currently regarded as the smoothest switches on the market.

Whether for PC, Mac OS, Linux, or even Android devices; Keychron keyboards are compatible and meet all requirements. The desired operating system is set via a switch on the keyboard frame. Each Keychron keyboard includes additional keycaps for Mac and Windows, as well as a keycap puller. For improved workflow and multitasking, you can connect up to three Bluetooth devices simultaneously and switch from laptop to tablet or mobile.

This Keychron keyboard features a fully hot-swappable PCB, meaning the switches are not soldered. This allows you to easily upgrade, swap, and mix the switches without soldering—just plug and unplug as desired. The keyboard is equipped with excellent RGB LED backlighting, providing an optimal and customizable typing experience. With 15 different lighting modes, you can create the desired atmosphere with blinking, breathing, or static effects.

This model features a sleek and elegant aluminum frame for increased durability and rigidity. The large 4000 mAh battery lasts up to nine days (8 hours a day for up to 72 hours) with the backlighting on, or four weeks with the backlighting off, and it fully recharges in just three hours.
