Keychron K5 Max: Specs, Features, Pros & Cons
Keychron built this keyboard around a short switch. Its low-profile Gateron switches and matching double-shot PBT caps bring a complete 108-key layout, numpad included, down to a height a laptop owner will recognize, and every press still travels like a mechanical one.
That puts the K5 Max in a narrow gap in the maker's catalog. The B6 Pro, Keychron's thin full-size office board, sits flatter still and runs far longer between charges, but it has no mechanical switches at all. This one keeps them, mounts them in hot-swap sockets that accept a different switch without solder, and ships with Browns or Reds to start. The case mixes ABS with aluminum, which keeps the weight low enough for a full-size board to travel in a work bag.
Connection is its other strength. A cable, a wireless dongle and Bluetooth are all there, three Bluetooth hosts are remembered at once, and every key and layer can be reassigned from a browser page through QMK and VIA. A work laptop, a home desktop and a tablet can share it without a new pairing each morning.
It is built for someone who types most of the day, uses the number pad for figures and would like one board on every desk they sit at. Gaming is outside its brief. Nothing inside is magnetic, there is no rapid trigger or adjustable actuation, and there is no rotary knob for volume.
Battery life trails the category, and switching on the backlight shortens it further, so expect the cable to stay plugged in more often than on most wireless keyboards.

How this VS Score was computed
Score 42: each known spec is measured against the median of all keyboards (101 products), then weighted; 50 means level with that median. In classes of six or more, a value beyond the class’s 10th–90th percentile range counts as that limit, so one extreme product cannot set the scale. 55% of the scoreable weight could be used; unknown values, features not applicable to this class and proxies (battery capacity where a rated life exists) add or remove nothing.

Editor’s note
The Keychron K5 Max is aimed at people who want a mechanical keyboard that does not dominate the desk. It uses low-profile Gateron switches that are about 31% shorter than standard MX-height ones, so the whole 108-key full-size board sits at roughly the height of a laptop keyboard while still typing like a mechanical.
The practical strengths are the ones you use daily. It is hot-swappable, so switches can be changed without soldering if the stock Browns or Reds are not to your taste. It connects three ways (USB-C, 2.4 GHz and Bluetooth 5.1) and pairs with up to three Bluetooth devices, which makes it easy to share between a work laptop, a personal machine and a tablet. QMK/VIA support means every key and layer can be remapped in a browser, and the double-shot PBT keycaps will not go shiny the way ABS does. At 424 x 119 mm and 720 g it is comfortably portable for a full-size board, and the 2,000 mAh battery lasts around 95 hours with backlighting off.
The limits are mostly about speed and comfort. Polling is 1,000 Hz on the dongle and wired, and drops to 90 Hz over Bluetooth, which is fine for typing but well short of the 8,000 Hz boards gamers now chase. Turn the RGB on and battery life falls to roughly 50 hours even at the lowest brightness. The ABS-and-aluminum frame is solid without feeling premium, and low-profile keycaps are a genuine adjustment if you are used to full-height caps.
Buy it if you type for a living, want a numpad, and prefer a slim board you can carry and remap. Skip it if you are buying primarily for gaming, want a high polling rate, or already know you dislike low-profile switches.

The bottom line
The Keychron K5 Max earns a VS Score of 42, below the median of the 101 keyboards it is measured against (a score of 50 is level with that median).
- Who it’s for
- A full-time typist who wants a numpad in a slim mechanical board that can travel and be remapped key by key.
- Who should look elsewhere
- Gamers should skip it, since polling is ordinary and nothing is magnetic. So should anyone who already dislikes low-profile keys.
- The trade-off that matters
- Battery life is short for a wireless board, and lighting cuts it further, so either keep the backlight off or keep the cable handy.
- The main alternative
- Keychron B6 Pro: a thin full-size board from the same maker with far longer battery life, if mechanical switches are not essential.
