A compact mechanical keyboard frees up desk space, improves the typing experience, and performs just as well for gaming as it does for work. The challenge is navigating the technical specifications, which often make promises that are hard to quantify: "quiet", "ergonomic", "gaming" or "customisable".
To choose an AJAZZ AK820 75 % mechanical keyboard without any nasty surprises, it's best to examine its layout, connectivity, component compatibility and the features that will genuinely make a difference in daily use.
A 75 % keyboard generally keeps the function row, arrow keys and several navigation keys, but does away with the numeric keypad. This means it takes up less space than a standard keyboard. However, it's less practical if you regularly enter tables of numbers.
The percentage also doesn't tell you the exact number of keys. Depending on the version, the spec sheet may state 82 or 83 keys. Take the time to check the illustrated layout on the product page before placing your order.
A US QWERTY gaming keyboard doesn't follow the layout of a French AZERTY keyboard. The position of letters, punctuation marks and certain symbols is different. Windows and macOS do allow you to change the language or input source in the settings, but the keycaps will still show QWERTY.
This layout can be useful for gaming, programming or using certain shortcuts. However, for typing in French all day, it requires an adjustment period, particularly for accents and punctuation.
RGB backlighting is mainly used to customise the keyboard's appearance and to make the keys easier to see in a dark room. It says nothing, however, about key stability or typing comfort. Some versions of the AJAZZ AK820 offer white lighting, while other listings mention RGB lighting.
So check the lighting colour and the effects available on the variant you choose, rather than relying solely on the range name.
The AJAZZ AK820 measures approximately 327 × 136 × 40 mm and weighs around 0.8 kg, according to the information provided for the wired version. Its 75 % format leaves more room for your mouse, which can make a real difference on a small desk. It also slips more easily into a carry bag.
The USB Type-C wired connection does away with recharging and eliminates concerns about battery life. It's particularly well suited to PC gamers, students and people who mainly work from a fixed desk. The trade-off is that you need to use a USB port and accept less mobility than with a wireless model.
Compatibility is stated for Windows and Mac, as well as certain Android devices. On consoles, an adapter may be necessary and is not supplied. Also remember to check that your computer has a suitable USB port.
The version equipped with linear red switches offers a smooth keystroke, with no tactile bump or distinct click. This feel can suit fast-paced gaming as well as typing. However, the noise level also depends on your typing force, the stabilisers and the surface the keyboard is placed on.
The hot-swap mechanical keyboard AJAZZ AK820 accepts 3-pin or 5-pin switches, depending on the product listing. This means you can replace the switches without soldering, as long as you use a suitable puller and check compatibility with the PCB. You'll therefore be able to upgrade later to a more tactile or quieter typing feel.
The term gasket mount refers to a flexible mounting of the plate and PCB, held in place by dampening elements. The keyboard also features a perforated polycarbonate plate for added flexibility, along with several layers of foam, including Poron foam and elements placed under the switches. The overall effect can make typing softer and reduce resonance, without eliminating mechanical noise entirely.
PBT OEM keycaps generally resist shine better than standard ABS keycaps. Their OEM profile, which is quite common, offers a familiar height for many users. Comfort, however, also depends on your wrist position, the keyboard's tilt and the height of your desk.
The CNC volume knob lets you adjust the sound quickly without leaving a game, video call or application. This is a real comfort gain, but check whether it's limited to volume control or can be reassigned to other functions using the compatible software.
Why this model suits this profile: It combines a 75 % format, Type-C wired connection, linear red switches and a volume knob in an accessible configuration for discovering the world of customisable mechanical keyboards.
The wired connection means you don't have to keep an eye on battery level, while the hot-swap PCB lets you change the typing feel without replacing the whole keyboard.
75 % format, PBT OEM keycaps, gasket mount, CNC knob and stated compatibility with Windows and Mac.
Why this model suits this profile: Users who want more options benefit from wired, Bluetooth and 2.4 GHz connections, a programmable button and customisable lighting.
The three connection modes mean you don't have to choose between mobility and wired use. According to the provided spec sheet, hot-swap also applies to all keys.
80 % layout, PBT keycaps, stated 4,000 mAh battery, lighting and customisation software.
Why this model suits this profile: Its more complete layout suits people who regularly use the numeric keypad while still wanting a customisable mechanical keyboard.
The 98 % format avoids the compromise of the 75 % when numbers and extra keys are essential for work.
Switches stated as pre-lubricated linear, PBT keycaps, gasket structure and compatibility with 3-pin or 5-pin switches.
We've put together a comprehensive list, updated in real time, of products that meet these demanding criteria as well as European safety standards.
Yes. The spec sheet states compatibility with Windows and macOS via the USB Type-C connection. However, the layout remains US QWERTY. You'll therefore need to select the correct input source in your system settings and get used to the different position of certain characters.
Yes, the model is stated as hot-swap and compatible with 3-pin or 5-pin switches. Unplug the keyboard before any intervention, use a suitable puller and never force it if a switch resists. New components must match the format supported by the PCB.
The manufacturer's spec sheet states up to 50 million keystrokes. This is a theoretical value provided by the manufacturer, which doesn't allow you to predict the exact lifespan of each keyboard. Dust, humidity, impacts and intensity of use can accelerate wear. To preserve the keyboard, clean it when unplugged and keep liquids away.
