“I have recently bought a Keychron K12, and I'm really satisfied with it. You can say that the build quality is high, and I love the sound of the switches.”
“Bought this in December 2023. The good first: - the typing experience is genuinely fantastic. The plastic case creates this resonant, almost bass-cabinet effect that makes every keystroke satisfying. - Gateron G Pro Red switches are solid as always. For pure…”

Keychron K12 vs V4: your questions
Both keyboards include keycaps for macOS. The K12 vendor page highlights it as a strong option for Mac enthusiasts. The V4 also includes Mac keycaps and has a system toggle to save separate layouts for macOS and Windows.
Yes, both the Keychron K12 and V4 feature hot-swappable sockets. The K12 supports both 3-pin and 5-pin MX-style mechanical switches, as well as Keychron's proprietary optical switches in certain versions. The V4's PCB also supports both 3-pin and 5-pin MX mechanical switches.
No. The Keychron V4 is a wired-only keyboard, connecting via its included USB Type-C cable. The Keychron K12 is the model that offers Bluetooth wireless connectivity alongside a wired mode.
The K12 uses north-facing LEDs (on the top side of the switch). The V4 uses south-facing LEDs (on the bottom side). South-facing LEDs, like on the V4, prevent interference with the stems of Cherry-profile keycaps, allowing for a wider compatibility with aftermarket sets.
The Keychron V4 comes with double-shot PBT keycaps, which are more durable and resistant to oil and shine. The Keychron K12 comes with ABS keycaps, which can develop a shiny surface with prolonged use. PBT keycaps are generally considered a premium feature.
The vendor description for the K12 does not mention native support for advanced reprogramming software like QMK or VIA. Its programmability appears limited to the onboard multimedia and lighting functions. For deep key remapping, the V4 with QMK/VIA is the supported choice.
According to the vendor, the V4 barebone version includes the ABS plastic case, the PCB with screw-in stabilizers, and the steel plate. It does not include keycaps or switches, allowing you to choose your own.
The manufacturer states the K12 non-backlit version can last up to 570 hours on a single charge, or about 2 months with 8 hours of daily use. The white and RGB backlit versions can last up to 240 hours with the backlight off.
The Keychron K12 is more beginner-friendly for users who want a simple, plug-and-play wireless experience. The V4 is beginner-friendly for those new to keyboard customization, as its hot-swap design and barebones kit make first-time building straightforward, but its wired nature and focus on modding cater to a different kind of beginner.
Only the Keychron V4 is listed with 'Knob Support' in its extra features metadata. The Keychron K12 does not have this feature listed, suggesting it does not support an encoder knob.
The Keychron K12 has a plastic plate. The Keychron V4 features a steel plate, which typically provides a stiffer, more consistent typing feel and influences the acoustic profile of the keyboard.
