Design

The design of the Keychron K3 is a balance between portability and functionality. Let's explore its key design aspects.

Dimensions
SizeCompact (75%)
Height1.1″ (2.8cm)
Width12″ (30.5cm)
Depth4.6″ (11.7cm)
Weight0.88 lb (0.4 kg)

The dimensions of the Keychron K3 make it a compact and portable keyboard. It is smaller in size compared to standard keyboards, measuring a little over 22mm at its thickest point. This slim form factor is suitable for those who want a keyboard that won't take up much space on their desk or in their bag.

Build Quality
Keycap MaterialABS

With a reinforced aluminium chassis, the Keychron K3 showcases a robust build quality with minimal flex. However, the keyboard utilizes thin ABS plastic keycaps, which might not offer the same durability as PBT or thicker ABS counterparts. Some users may observe a slight wobble in keys and the double shot keycaps might be prone to oil shine over time. Despite these trade-offs, the overall build quality remains solid and reliable.

Ergonomics
Minimum Incline

The Keychron K3 offers a comfortable typing angle and convenient placement of the power port. However, it lacks incline settings and a wrist rest, which may limit customization and ergonomic support. The 75 percent layout of the keyboard includes arrow keys, a function row, and five out of the six keys normally placed above the arrow key cluster. It also offers Mac- and Windows-compatible media keys on the function row.

Backlighting
BacklightingYes
Per-Key BacklightingYes
EffectsYes

The Keychron K3 offers different options for backlighting. It is available with either a white backlight or an RGB backlight option. The keyboard features thin ABS plastic keycaps with crisp legends that allow the backlighting to shine through. Some reviewers mention that the full RGB backlighting with individually-lit keys is a standout feature, although the brightness may not be sufficient in well-lit environments.

Connectivity
ConnectivityWireless
Cable DetachableYes (Wired Mode and Charge)
Cable Length4′ (1.2m)
ConnectorUSB type-C

The Keychron K3 offers multiple connectivity options. It can be connected wirelessly via Bluetooth 5.1 or through a wired connection using the included USB-C cable. The Bluetooth connection allows pairing with up to three devices, offering convenience for those who switch between multiple devices.

Extra Features
Media KeysHot Keys
Lock IndicatorCaps Lock

The Keychron K3 offers some additional features that enhance its functionality. It has hot-swappable switch options, allowing users to change the switches without soldering. The keyboard also includes a small switch for layout customization and comes with Mac-specific and Windows-specific keycaps. Additionally, it includes a plastic dust cover, keycap puller, switch puller, USB-C cable, and extra rubber feet.

Typing Experience

The typing experience is crucial when considering a keyboard. Here's a breakdown of the Keychron K3's typing performance.

Keystrokes
Operating Force51 gf
Actuation Force48 gf
Activation Point1.7mm
Total Travel2.7mm

The Keychron K3's keystrokes are influenced by its low-profile optical switches. These switches have a shorter travel distance compared to regular switches, measuring 10.77mm in height. This design choice contributes to the keyboard's slim form factor.

Typing Quality
Switch NameGateron Low Profile Brown
FeelTactile

The typing quality of the Keychron K3 is subjective and dependent on personal preferences. The K3 utilizes low-profile switches, which provide a different typing experience compared to regular mechanical switches. The typing quality is satisfying, especially with the Gateron Low Profile Brown switches, which offer a tactile feel and low pre-travel distance. However, the overall typing experience may be less enjoyable for users accustomed to traditional switches.

Typing Noise

The typing noise of the K3 depends on the switches chosen. Brown and orange switches, for instance, produce different sounds. While the blue Gateron switches are clicky and louder, brown switches offer a quieter typing experience. This versatility in noise levels allows users to choose based on their preference for auditory feedback.

Latency
Wired14.6ms
Bluetooth22.1ms

The K3 shows decent latency, suitable for casual gaming or daily tasks. It supports a 1,000Hz polling rate in wired mode, providing a fast response. However, while its Bluetooth functionality offers wireless convenience, it might not perform as well for gaming, making the keyboard less ideal for competitive or fast-paced gaming environments.

Software

The software aspect of a keyboard affects its customization and compatibility. Let's dive into the Keychron K3's software capabilities.

Programming
Software NameNo Software
ProfilesNo Profile

The programming aspect presents a mixed bag. With Keychron K3, native key remapping is not supported, limiting reconfigurations and additions to OS-level programming. This lack of support extends to macro-programmable keys, with no companion software available.

The process of programming the keyboard can be intricate, involving multiple steps before the tool recognises the board. However, after this initial setup, adjusting the layout becomes a much simpler task. The keyboard can be programmed with tools such as QMK or VIA, widely adopted in the mechanical keyboard community. This process requires wired mode and utilises a web tool with a JSON file from Keychron's website. Alternatively, Keychron suggests using software like Karabiner for Mac or SharpKeys on Windows for remapping.

Compatibility
WindowsFull
macOSFull
AndroidFull
iOSPartial

The Keychron K3 series exhibits a broad compatibility, working smoothly with both Windows and Mac systems. Notably, it includes a switch to toggle between Mac/iOS and Windows/Android layouts. It ensures most keys operate seamlessly with macOS, with the exception of screen brightness hotkeys. The keyboard also runs with Linux when set to Mac/iOS, again excluding screen brightness hotkeys. Android compatibility is offered too, with the exception of the F3 hotkey. Full iOS and iPadOS compatibility is present, barring the F3 and F4 hotkeys.

Beyond operating systems, the keyboard is compatible with all standard devices and can be recharged using the same USB-C cable that powers full-sized tablets.
