Compare Keychron K3 V3 vs V3 Max Differences Side by Side

The Keychron V3 Max has a significantly larger 4000mAh battery, while the K3 V3 has a 1550mAh battery. According to the manufacturer, the V3 Max can last up to 190 hours with backlighting off, giving it a clear advantage for long-term wireless use.

No. The Keychron K3 V3 is designed for low-profile mechanical switches only. The vendor states it is compatible with Keychron Milk POM switches or Gateron/Keychron low-profile mechanical switches. It does not support standard MX-style switches.

The V3 Max uses a gasket mount, where the plate is suspended by rubber or silicone gaskets to absorb vibrations and create a softer, more consistent typing feel. The K3 V3 uses a top mount, where the plate is screwed directly into the top case, typically resulting in a firmer and more direct feedback.

Yes. Both the Keychron K3 V3 and V3 Max are listed as compatible with Mac and Windows systems. They include keycap sets for both operating systems and have a physical toggle switch to change between macOS and Windows key mappings.

Both keyboards fully support QMK and VIA for deep key remapping and macro programming. The V3 Max may have a slight edge for hardware modders due to its gasket mount, screw-in stabilizers, and broader switch compatibility, but the firmware customization is equally powerful on both.

Yes. The Keychron V3 Max includes both 2.4 GHz wireless and Bluetooth 5.1. The vendor description confirms it comes with both Type-C and Type-A receivers for the 2.4 GHz connection, which can be stored in a magnetic slot on the keyboard.

The K3 V3 uses LSA profile (Low profile with spherical angle) shine-through ABS keycaps. The V3 Max uses OSA profile (OEM height, SA shape) double-shot PBT keycaps that are not shine-through.

The K3 V3 is designed for a low-profile typing experience and includes three levels of adjustable typing angles (2.5°, 4.2°, 6.5°) for ergonomic support. It also features multiple layers of acoustic foam, which the vendor states enhances comfort and reduces noise.

The V3 Max is listed with 'Knob Support,' and the fully assembled version includes a knob. It is likely the PCB has support for a knob, but you would need to confirm if a barebones kit or aftermarket parts are available to add one separately if you purchase a non-knob version.

Both keyboards have sound-dampening features. The K3 V3 includes IXPE, EPDM, and latex foam. The V3 Max has a gasket mount design and sound-absorbing foam. Without direct decibel measurements, the V3 Max's gasket mount is typically associated with a softer, potentially quieter sound signature, but the K3 V3's foams are also aimed at noise reduction.

The vendor descriptions do not specify if the stabilizers are pre-lubed. However, the V3 Max uses screw-in PCB stabilizers, which are generally easier to remove, mod, and lube yourself compared to clip-in stabilizers.
