Keychron K1 Max vs K3

The K1 Max uses low-profile Gateron/Keychron mechanical switches with a standard MX stem, and it comes with double-shot PBT keycaps. You can replace the keycaps with other low-profile MX-compatible keycaps, but standard Cherry MX keycaps may not fit properly due to the low-profile switch height.

No, the Keychron K3 does not support QMK or VIA firmware according to the vendor description. Its customization is limited to the preset backlight settings and built-in key functions, which are configured through hardware shortcuts rather than a software configurator.

The K1 Max has a larger 4000mAh battery compared to the K3's 1550mAh battery, which suggests it can last longer between charges under similar usage. However, battery life depends on backlight brightness and connection type, so actual runtime varies.

Yes, the K1 Max is hot-swappable and supports low-profile Gateron and Keychron mechanical switches. The vendor specifies it is not compatible with low-profile optical switches due to QMK limitations, but you can swap between linear, tactile, or clicky low-profile mechanical switches without soldering.

Yes, the Keychron K3 supports Bluetooth 5.1 connectivity, allowing you to pair and switch between multiple devices such as a laptop, smartphone, and tablet. It does not have a 2.4 GHz wireless option, so the connection is limited to Bluetooth and wired via USB-C.

Yes, the vendor description states that the K1 Max supports 2.4 GHz wireless connectivity in addition to Bluetooth and wired modes. The 2.4 GHz mode features a 1000 Hz polling rate, which is ideal for gaming where low latency is important.

Keychron has redesigned the stabilizers on the K1 Max for better stability and reduced wobble on larger keys like the space bar, left Shift, backspace, and Enter key. The vendor notes these stabilizers stay level with the switches for improved reliability.

The K3 uses low-profile Optical switches with an MX-style stem, which allows for compatibility with some standard MX keycaps. However, the vendor warns that using standard caps may affect the low-profile feel, and the keyboard is not compatible with conventional MX mechanical switches.

The K1 Max includes 12 multimedia keys according to the vendor's specification section. These keys provide quick access to media controls like volume, play/pause, and skip, which are useful for content creation and office work.

Both keyboards are designed with macOS compatibility in mind, offering Mac multimedia key layouts and extra keycaps for both macOS and Windows. The K1 Max includes keycaps for both operating systems, while the K3 also comes with extra keycaps, making either suitable for Mac users.

Yes, the K1 Max is compatible with the Keychron Launcher web app for customizing key mappings and macros. The vendor notes that you need to use the latest version of Chrome, Opera, or Edge browser and connect the keyboard via wired mode to use the Launcher.

The K1 Max has an 80% TKL layout (88 keys) with a full function row and navigation cluster, while the K3 uses a more compact 75% layout. The K3 saves additional desk space by tightening the key cluster but still includes essential multimedia and function keys.
