Product Description

The Keychron K4 US Version 2 is a compact mechanical keyboard with a 96% layout that includes a number pad, suited for users who want full-size functionality in a smaller footprint. It fits well for office work, casual gaming, and mobile device use, especially if you value wireless connectivity and switch customization without soldering. Its design supports both Mac and Windows users, including Mac multimedia keys, making it a versatile option for mixed-device environments.

Key Features

Hot-swappable switches allow easy customization of typing feel without soldering, compatible with most MX-style 3-pin and 5-pin mechanical switches.
Bluetooth 5.1 supports connection to up to three devices, enabling quick switching between smartphone, laptop, and tablet.
Full 100-key layout with a relocated Delete key offers access to essential keys while saving desk space.
Large 4000mAh battery provides extended wireless use, with up to 240 hours typing time when backlight is off.
Adjustable RGB backlighting with over 15 lighting modes lets users personalize the keyboard’s appearance.

Build Quality

The keyboard comes in plastic or aircraft-grade aluminum frame options, balancing durability and weight. An inclined bottom frame improves typing comfort over long sessions. Keycaps are ABS, which may wear faster than PBT but support the included backlighting well.

Typing Experience

Users can choose between Gateron Red, Blue, or Brown switches, covering linear, clicky, and tactile preferences. The hot-swappable feature enables easy switch replacement or upgrades. The keyboard’s layout and keycap sizing support efficient typing, though ABS keycaps may feel less premium.

Connectivity and Compatibility

Supports both wired USB Type-C and wireless Bluetooth modes. Compatible with macOS, Windows, Android, and iOS. Mac users benefit from dedicated multimedia keys. Linux support exists but may require community assistance. Switching between devices is seamless via Bluetooth.

Trade-offs

ABS keycaps may show wear faster than higher-end materials.
Num Lock functionality is limited to Windows OS only.
RGB lighting reduces battery life significantly compared to backlight off mode.
Relocated Delete key may require adjustment for users accustomed to standard layouts.
