Keychron V3 Max vs V4 Max80% vs 60% Layout Comparison

The primary difference is the layout size. The V3 Max is an 80% TKL keyboard with dedicated arrow keys, function row, and a navigation cluster. The V4 Max is a 60% keyboard, which omits these dedicated keys to achieve a much smaller footprint, requiring the use of function layers to access those functions.

Yes. Both the V3 Max and V4 Max feature triple-mode connectivity. They support 2.4 GHz wireless with a 1000 Hz polling rate, Bluetooth 5.1 for connecting to multiple devices, and wired USB-C operation. Keychron states both include dual Type-C and Type-A receivers for the 2.4 GHz connection.

Yes, both models are hot-swappable. Their PCBs support both 3-pin and 5-pin MX-style mechanical switches, allowing you to install switches from brands like Gateron, Cherry, or Kailh without soldering.

The V3 Max is generally better suited for programming. Its TKL layout provides immediate access to arrow keys and a navigation cluster, which are heavily used in code editing and debugging, without needing to press a function layer key first.

Yes. According to Keychron's product descriptions, the fully assembled versions of both the V3 Max and V4 Max include double-shot PBT keycaps with additional keycaps for both macOS and Windows layouts. A physical switch on the keyboard toggles between the operating systems.

Both keyboards have the same 4000mAh rechargeable battery. Keychron's specifications list a wireless working time of up to 190 hours with the backlight off, and up to 100 hours with the RGB lighting at its lowest brightness, under lab conditions.

Yes. The Keychron V3 Max metadata shows support for multiple ISO layouts, including UK, German, French, Spanish, and Nordic. The V4 Max, however, is listed as ANSI-only.

The Keychron V4 Max is significantly more portable. It is smaller (305mm long vs. 368mm) and lighter (645g vs. 895g) than the V3 Max, making it much easier to fit in a backpack or use in a confined space like a coffee shop table.

Yes. Both the V3 Max and V4 Max are fully programmable using the open-source QMK firmware and the VIA configurator. Keychron also provides its own web-based Launcher app for remapping keys and creating macros without flashing firmware.

Both keyboards use a gasket mount design with a polycarbonate plate, which aims to provide a softer, more flexible typing feel and reduce acoustic resonance. The V4 Max also lists an optional steel plate in its metadata for a firmer feel.

The product descriptions do not specify if the screw-in PCB stabilizers are pre-lubed from the factory. However, they are screw-in stabilizers, which are generally considered premium and are user-serviceable, meaning you can lube or modify them yourself.
