Keychron K5 Max — full-size low-profile wireless keyboard, ISO layouts

At a glance

7.8 mm without keycaps

A full-size board 18.2 mm tall at the front and 720 g — thinner than most laptops.

109 keys

A complete 100% layout, number pad included, with twelve media keys in the top row.

QMK and VIA

Every key, layer and macro remapped in the Keychron Launcher web app.

2000 mAh

About 95 hours with the backlight off, about 50 at the lowest RGB brightness.

A full-size board that is almost flat

7.8 mm at the front without keycaps, 18.2 mm with them, and 720 g across 424 millimetres. A low-profile board keeps the hand close to the desk, so the wrist does not have to climb to reach the keys — and on a keyboard with a number pad, that adds up over a day of data entry.

LSA keycaps, low and dished

The keycaps are LSA profile — low profile, spherically dished, angled — so the fingertip settles into the key rather than sliding over it. Double-shot PBT: the legend is a second piece of plastic, not paint, so it cannot wear off, and PBT does not take the shine ABS develops with use.

Hot-swappable, low profile

Switches pull out and push in without a soldering iron. One limit is worth knowing before ordering: the K5 Max takes Gateron and Keychron low-profile mechanical switches only, because QMK does not support low-profile optical switches.

Redesigned stabilisers

The long keys — spacebar, shift, enter, backspace and the zero on the number pad — run on the stabilisers redesigned for the Max series, pre-lubricated so they land evenly rather than clattering on one side.

QMK and VIA, in a browser tab

The board runs open-source QMK firmware, and every key, layer and macro is remapped in the Keychron Launcher web app — nothing to install, and the mapping is written into the keyboard so it travels with it. The 22 RGB backlight modes are set the same way.

Mac and Windows on one board

The board works the same on macOS, Windows and Linux, with the extra modifier keycaps for both systems in the box and twelve media keys along the top row. Three typing angles — 3.37°, 4.36° and 6.56° — on flip-out feet.
