Keychron K1 Pro vs K5 ProLow-Profile 80% vs Full-Size Choice

The main difference is the layout size. The K1 Pro is an 80% tenkeyless (TKL) keyboard, meaning it lacks a number pad. The K5 Pro is a 100% full-size keyboard that includes a dedicated number pad and navigation cluster. Their core features like switches, programmability, and build materials are otherwise identical.

Yes, both keyboards offer hot-swappable versions. According to Keychron, this allows you to customize your typing experience by swapping Gateron low-profile mechanical switches without soldering. It is important to note the vendor states both models are currently compatible only with Gateron low-profile mechanical switches, not optical switches.

Yes, both the K1 Pro and K5 Pro support key remapping and macro programming through the open-source QMK firmware. Keychron states you can use the Keychron Launcher web app for customization. The product listings also mention VIA support, though some user reviews for the K5 Pro note challenges with VIA compatibility, suggesting the Launcher may be the primary supported method.

The Keychron K1 Pro is better for a small desk. Its 80% layout measures 346mm in width, which is significantly more compact than the 435mm width of the full-size K5 Pro. The K1 Pro's smaller footprint frees up valuable space for your mouse and other desk accessories.

Yes, both keyboards are fully compatible with macOS and Windows. Keychron includes keycaps for both operating systems in the box, along with additional Escape and Enter keys. The vendor description confirms you can configure different keymaps for Mac and Windows devices using the Keychron Launcher.

Both keyboards are equipped with the same 2000mAh battery. Keychron does not provide an estimated battery life in hours, but given the identical battery capacity and similar feature sets (like RGB backlighting), you can expect comparable wireless runtime between the two models under similar usage conditions.

Both keyboards come with low-profile double-shot PBT keycaps, which are durable and oil-resistant. The K1 Pro keycaps are designed for its 87-key TKL layout, while the K5 Pro keycaps are for its 108-key full-size layout. Both sets use an LSA (low profile spherical-angled) profile and include keys for both Mac and Windows.

The keyboards are designed for Gateron low-profile mechanical switches. The vendor specifications explicitly state that both the K1 Pro and K5 Pro are currently compatible with Gateron low-profile mechanical switches only, as QMK does not support low-profile optical switches. You can choose from linear (Red), tactile (Brown), or clicky (Blue) variants.

The Keychron K1 Pro is more portable. It is not only 89mm narrower than the K5 Pro, but it is also 140 grams lighter (580g vs 720g). This smaller size and reduced weight make the K1 Pro significantly easier to pack in a bag or carry between locations.

Yes, both keyboards are available in RGB backlight and white backlight versions. According to the manufacturer, the RGB version offers more than 22 types of backlight settings, with the ability to fine-tune hue, saturation, brightness, and effect speed. The white backlight version has 14 types of settings.

Both keyboards feature a hybrid frame construction made of ABS plastic and aluminum, giving them a solid feel. They include redesigned stabilizers for less wobble on large keys, a low-profile typing angle of 3 degrees with three levels of adjustment, and north-facing RGB LEDs. The use of double-shot PBT keycaps also contributes to long-term durability.
