AK820 Mechanical Keyboard (Black)

AJAZZ AK820 – A Reliable Mechanical Keyboard That Gets the Job Done

The AJAZZ AK820 is a mechanical keyboard with solid build quality, a clean layout, and features that make sense. It’s made for people who want a better typing or gaming experience without overspending. It’s not trying to be the flashiest board on your desk. It just works well.

We chose to stock the AK820 because it’s well-reviewed by real users and known in the keyboard space for offering more than you’d expect at this price. It’s a solid choice whether you're looking for your first mechanical keyboard or replacing a louder, bulkier setup.

Key Features and Layout

Switches: EPOMAKER Light Bright Moon – smooth linear switches with consistent feel

Mount Style: Gasket-mounted – softer keypress, less noise, better typing comfort

Connection: Wired, USB-C to USB-A – simple and reliable

Keycaps: Double-shot PBT – durable with a clean, matte finish

Layout: 75% – saves space but keeps essential keys

RGB Lighting: Customisable modes with onboard controls

Hot-Swappable PCB: Swap switches easily, no soldering needed

The 75% layout includes arrow keys and a function row, but cuts out the numpad to save desk space. If you’ve only ever used full-size boards, you’ll still find this layout easy to adapt to. The keycaps don’t shine through, so the lighting gives a subtle glow — not too loud, not too dull.

Why It’s a Good Fit for Gaming

The AK820 works well as a gaming keyboard. It has a fast response thanks to the linear switches and wired connection. You won’t get input lag or double presses. It has full key rollover, so you can press multiple keys at once without problems. It’s quiet enough for shared setups and sturdy enough to handle daily use.

RGB lighting is adjustable, but it’s not the main feature here. The performance is.

Why It Works for Everyday Use

This keyboard also fits into everyday routines. The layout is efficient. The switches feel smooth and don’t wear out your fingers after long typing sessions. Whether you're working from home, studying, or just chatting online, it holds up.

The gasket mount gives a soft feel while typing — more comfortable than a budget mechanical keyboard. It helps with fatigue, especially if you're typing for hours.

Honest Build Quality

The board is plastic but well put together. No sharp edges. No rattle. It feels more solid than most in this range. The stabilisers (the parts under long keys like spacebar) come pre-lubed and feel decent out of the box. If you want to mod it later, you can — but it’s good enough as it is.

Why We Chose It for STEM

We started STEM Keyboards to offer affordable, high-quality mechanical keyboards in the UK. There are too many overpriced options and not enough that hit the sweet spot between quality and cost. The AK820 does that.

We only list boards that have strong community feedback and pass our own checks. We’re not here to sell you something just because it’s trending. If it’s listed on STEM, it’s because we’ve tested it and it holds up. About STEM
