“Great keyboard but K2 is too small for my clumsy hands... not their fault. A larger one may have worked better for me. Otherwise I like everything about it.”
Keychron K4 Pro

“I previously had a normal K4 and i love the new one, the only thing is that the stabilizers lube work is kinda bad and the space bar was very rattly but after some lube work the K4 pro retakes the perfect productivity keyboard.”

Keychron K2 V2 vs K4 Pro: your questions
Both keyboards feature a 4000mAh battery. The K2 V2 is advertised to last up to 240 hours with backlight off. The K4 Pro has the same battery capacity, but its actual run time may vary slightly due to the extra LEDs and a larger PCB, though no official runtime figure is provided for the K4 Pro.
The K2 V2 does not support QMK or VIA firmware, so key remapping is limited to onboard shortcuts. For deep customization, the K4 Pro is the better choice as it offers full QMK/VIA support for remapping any key or creating macros.
Yes, both the fully assembled and barebones versions of the K4 Pro are hot-swappable. They accept almost all 3-pin and 5-pin MX-style switches without soldering, as per the manufacturer.
The K4 Pro is better for programming because it supports QMK/VIA firmware, allowing you to remap keys, create macros, and program custom layers. It also has screw-in PCB stabilizers for more stable big keys, and OSA profile PBT keycaps for comfortable typing.
The K2 V2 offers 18 types of RGB lighting, while the K4 Pro offers more than 22 RGB backlight settings. The K4 Pro uses south-facing RGB to avoid interference with Cherry-profile keycaps, whereas the K2 V2 uses north-facing RGB.
The Keychron K2 V2 is more travel-friendly due to its compact 75%, 84-key layout and lighter construction. The K4 Pro weighs 1280g, making it heavier and bulkier for portability.
Yes, the K4 Pro uses a 96% layout that includes a number pad, making it ideal for data entry, spreadsheet work, and content creation tasks that require quick numeric input.
Yes, both the K2 V2 and K4 Pro come with keycaps for both Windows and macOS. They also feature a switch to toggle between the two operating systems.
The K4 Pro uses screw-in PCB stabilizers, which are mounted directly to the PCB for less wobble on large keys. The K2 V2 does not specify the exact stabilizer type in its documentation.
The K4 Pro is specified with a 1000 Hz polling rate in wired mode, which is beneficial for gaming latency. The K2 V2 does not list a polling rate in its specifications, so its performance may not match the K4 Pro for competitive gaming.
The K2 V2 does not offer a barebones or DIY kit version according to its vendor listings. The K4 Pro is available as a barebones option, allowing you to supply your own switches and keycaps.
Only the K4 Pro is described as having sound-absorbing foam and a thick silicone dampening bottom pad. The K2 V2 does not mention any sound dampening materials in its specifications.
