Keychron K4 Max vs K5 QMK V2Layout vs Low Profile

The Keychron K4 Max has a larger 4000mAh battery, while the Keychron K5 QMK V2 has a 2000mAh battery. This means the K4 Max can typically last longer between charges, especially when used wirelessly.

Yes, but the experience differs. The K4 Max supports a 2.4 GHz connection with a 1000 Hz polling rate, making it suitable for competitive gaming. The K5 QMK V2 only supports Bluetooth for wireless use (with a 125 Hz polling rate), which introduces more latency.

Yes, both the Keychron K4 Max and the Keychron K5 QMK V2 feature QMK open-source firmware and support the Keychron Launcher web app. This allows you to remap keys, create macros, and customize lighting without installing software.

The K4 Max uses durable, double-shot PBT keycaps with an OSA (OEM Spherical Angle) profile. The K5 QMK V2 uses shine-through ABS keycaps, which are more prone to developing a greasy shine over time but allow more light to pass through for the RGB backlight.

The K4 Max is generally better for modding. It is hot-swappable and compatible with almost all standard 3-pin and 5-pin MX switches. It also features screw-in stabilizers and multiple layers of foam, which are common starting points for modifications.

Yes, both keyboards come with a system toggle and include additional keycaps for both macOS and Windows. You can also save different keymaps for each operating system using the Keychron Launcher software.

The K4 Max offers a traditional mechanical keyboard feel with standard-profile switches and PBT keycaps. The K5 QMK V2 features an ultra-slim, low-profile design with Keychron Milk POM switches, providing a much shorter key travel and a more laptop-like typing experience.

This information is not provided in the product listings for either the K4 Max or the K5 QMK V2. You would need to check the product's 'What's in the box' section or the vendor's website for the most accurate unboxing list.

The K5 QMK V2 features an ABS frame with an aluminum top frame, giving it a sturdier and more premium feel. The K4 Max uses an all-ABS plastic case, which is lighter and less expensive but may not feel as solid.

Yes, both keyboards can be used in wired mode via USB-C. When wired, both offer a 1000 Hz polling rate, which provides the lowest possible latency for competitive gaming or any task that requires instant response.

The K4 Max's hot-swap sockets are compatible with almost all 3-pin and 5-pin MX style mechanical switches (e.g., Cherry, Gateron, Kailh). The K5 QMK V2's compatibility is more limited, working only with Keychron low-profile mechanical switches or Gateron low-profile 2.0 switches.
