Keychron K1 V6 vs V1 MaxLow-Profile vs Custom 75%

The V1 Max has a significantly larger 4000mAh battery compared to the K1 V6's 2000mAh. The vendor states the V1 Max can achieve up to 190 hours of use with the backlight off and up to 100 hours at the lowest brightness. The K1 V6's battery is not specified for runtime, but the capacity is half that of the V1 Max.

Yes, the V1 Max uses standard MX-style switches and comes with double-shot PBT keycaps in an OSA profile. Because it supports 3-pin and 5-pin MX switches, you can easily replace the keycaps with any Cherry, OEM, or other standard MX compatible sets.

No, the K1 V6 uses low-profile switches and unique LSA profile keycaps. The vendor notes it is only compatible with Keychron Milk POM switches or Gateron/Keychron low-profile mechanical switches, so standard MX keycaps will not fit.

The V1 Max is generally better suited for programming. Its gasket mount design and PC plate provide a softer feel for long typing sessions. It also includes screw-in PCB stabilizers for steadier large keys and supports a knob, which can be programmed for tasks like scrolling through code.

Yes, the V1 Max supports both QMK firmware and VIA software, as confirmed in the product title and vendor description. This allows for deep customization of keymaps, macros, and shortcuts via the Keychron Launcher web app or VIA software.

Yes, the RGB Backlight Hot-Swappable version of the K1 V6 is hot-swappable. This allows you to change switches without soldering, though it is only compatible with Keychron Milk POM switches or Gateron/Keychron low-profile mechanical switches.

The K1 V6 offers a low-profile, ultra-slim typing experience with a top mount design and lower profile switches, resulting in a shorter key travel. The V1 Max has a standard profile with a gasket mount and a PC plate, which provides a softer, more cushioned bottom-out feel and reduced resonance.

The K1 V6 is more portable. It weighs 596g and has a very slim profile, making it easier to slip into a laptop bag. The V1 Max is heavier at 770g and has a thicker standard profile, making it less ideal for frequent travel.

Yes, the V1 Max is available as a barebones version, which does not include keycaps or switches. This is ideal for enthusiasts who want to build a custom keyboard from scratch using their preferred components.

No, the K1 V6 does not feature a knob. It relies on dedicated multimedia keys for volume and media control. The V1 Max, in contrast, is available with a knob version.

Yes, the V1 Max is built with Mac users in mind while retaining full Windows compatibility. It includes a system toggle and an additional set of customized keycaps for both Windows and macOS systems, allowing you to save two different layouts.

The V1 Max uses screw-in PCB stabilizers, which the vendor says provide a smoother typing experience with less wobble on larger keys. It also supports third-party screw-in PCB stabilizers.
