Two compact keyboards, and the difference between them is not a preference for how typing feels. It is a difference in what each one is built to do. The Keychron Q1 is a 75 percent gasket-mounted mechanical keyboard with a full aluminium case, hot-swappable switches and USB-C wired connectivity, with the wireless 75 percent aluminium board sold separately as the Q1 Max. The Logitech MX Keys Mini is a compact low-profile wireless keyboard with backlit spherical keycaps, multi-device switching and USB-C charging, and its recorded switch type is scissor keys with 1.8 mm of total travel.
Every value in this page comes from the specifications recorded against each product, and each of those values carries the manufacturer page it was read from. No keyboard was measured for this comparison, so nothing here describes how a board types, how loud it is, or how a switch behaves. Where the catalogue does not record something, this page says so rather than filling the gap.
What actually differs
Mechanism, and whether it can be changed later. The Q1 records its switch options as Gateron G Pro, Gateron Phantom and Keychron K Pro, all hot-swappable, and hot-swappable switches appear in its recorded feature list alongside backlighting and a gasket mount. The MX Keys Mini records its switch type as scissor keys with 1.8 mm of total travel, and its recorded feature list holds multi-device switching and wireless connectivity, with no switch that could be replaced. One of these keyboards can be opened and re-switched when the preference changes. The other cannot.
Wired against wireless. The Q1 records its connectivity as USB-C wired, and the same record notes that the wireless 75 percent aluminium board is sold as the Q1 Max. Its recorded feature list says there is no wireless connectivity on this board. The MX Keys Mini records Bluetooth and Logi Bolt connectivity, a 10 m wireless range, a battery life of up to 5 months with the backlighting off and up to 10 days with it on, a 1,500 mAh rechargeable lithium polymer battery and USB-C charging. One of these keyboards is tethered to the desk by a cable, and the other is not.
Layout. The Q1 records a 75 percent layout, which keeps an arrow cluster and a right-hand column while dropping the function row and the number pad. The MX Keys Mini records a compact layout with a function row. Neither records a number pad, and neither board can grow one later.
Case, mount and mass. The Q1 records aluminium as its case material, a gasket mount with a steel plate, double-shot PBT keycaps that are not shine-through, a polling rate of 1000 Hz, and a weight of 1,825 g plus or minus 10 g. The MX Keys Mini records a weight of 506 g, a figure the catalogue marks as only partially verified, and records no case material and no mount style at all. The mass difference is roughly three and a half times, and it is the clearest single reason the Q1 stays on a desk while the Mini moves with a laptop.
Who should pick which
The Q1 is the choice for a buyer who wants a substantial board that stays planted on the desk, who expects to try more than one switch type, and who accepts a fixed footprint, a weight that rules it out of a laptop bag, and a cable. Its recorded aluminium case, gasket mount and hot-swappable sockets are the reasons.
The MX Keys Mini is the choice for a buyer who types on flat, quiet keys, who moves between a laptop and a desktop, and who would rather not charge a keyboard on a schedule or run a cable across the desk. Its recorded multi-device switching, its recorded 10 m range and its recorded battery figure of up to 5 months with the backlighting off address exactly that, and a shared desk where mechanical key noise would be a problem is the situation its recorded low-profile build suits.
Neither board suits a buyer whose work depends on a number pad, because neither records one and neither can be extended to include one.
What this comparison does not settle
It does not settle price, because no price is recorded for either product, and it does not settle availability. It does not settle typing feel, sound or latency, because no board was measured and no such figure is recorded. It does not settle the MX Keys Mini weight precisely, because the catalogue marks that value as only partially verified. What it does settle is the mechanism, the wired and wireless arrangements, the layout, the recorded case and mount, the recorded mass and the recorded battery figures, which is enough to rule either product in or out for a large share of buyers.
