“My first better keyboard and I am absolutely satisfied. We'll see how it works after a longer time. I just thought of one small thing, I have nowhere to hide the receiver when I leave with just the laptop and I want to leave the keyboard at home. Like you can…”
“Beware of the double-clicking issue. I have got 2 units of this. They're both having the same problem and worse.”

Keychron K1 Max vs S1: your questions
The K1 Max is generally better for gaming because it supports a 2.4 GHz wireless connection, which eliminates cable drag while offering a 1000 Hz polling rate. The S1 is also wired with a 1000 Hz polling rate and is a very capable gaming keyboard, but it lacks the wireless freedom of the K1 Max.
No, the Keychron S1 is a wired-only keyboard. It connects via USB-C and does not have any built-in battery or wireless radios. If you need wireless, the Keychron K1 Max is the better option.
The Keychron S1 is significantly heavier at 960 grams, compared to the K1 Max which weighs 608 grams. The S1's weight comes from its full CNC machined aluminum body and steel plate, giving it a very solid and stable feel on a desk.
Yes, the K1 Max is designed for both Mac and Windows. It includes keycaps for both operating systems and has a system toggle. You can also configure different keymaps for each OS using the Keychron Launcher web app.
Yes, both the K1 Max and S1 are available with hot-swappable sockets. They both support low-profile Gateron mechanical switches. The K1 Max hot-swap option is included by default per the vendor, and the S1 offers it as an option.
Both keyboards come with low-profile double-shot PBT keycaps in an LSA (low profile spherical-angled) profile. These keycaps are designed to be oil-resistant and durable. The K1 Max keycaps are non-backlight shine-through, and the S1 keycaps are also not shine-through.
The K1 Max has a built-in 4000mAh battery and supports wireless modes, so it has battery life to consider. The Keychron S1 is wired-only and has no battery, so this comparison is not applicable to the S1.
The Keychron S1 is generally considered to have a higher build quality due to its full CNC machined aluminum body and steel plate, offering a denser and more premium feel. The K1 Max uses an ABS frame with an aluminum plate, which is lighter but less solid.
Yes, both keyboards support QMK and VIA for full key remapping, macros, and shortcuts. The K1 Max also supports the Keychron Launcher web app. This makes both keyboards highly customizable for productivity and gaming.
The K1 Max has an 80% TKL layout with 88 keys, which includes a dedicated navigation cluster and function row. The S1 has a more compact 75% layout, which is shorter and lacks a dedicated navigation cluster, but still has the function row.
