Overview
The EPOMAKER Ajazz AK820 PRO ISO-ES Teclado Mecánico Inalámbrico con Pantalla & Perilla is a 75% wireless mechanical keyboard with a 1.14-inch TFT color display and a rotary knob.
The Spanish product name translates to "wireless mechanical keyboard with display and knob." If you want a screen, a knob, a gasket mount and triple-mode connectivity for around ¥20,000, it is a strong option.
The catch is that this version uses a Spanish ISO layout. If you buy it expecting a JIS or US ANSI layout, the legends on the keys will not match the characters you get.
The 75% layout fits 82 keys. It drops the numpad but keeps the function row and the arrow keys.
Because the board is narrower than a full-size keyboard, your mouse can sit closer to the center of your body. The display can show the date, time, RGB settings and system information, and the knob controls volume or navigates the display.
Being able to check the keyboard's status at a glance is the main difference from boards without a screen.
Connectivity covers Bluetooth 5.1, 2.4GHz wireless and USB-C wired, and the board has a 4000mAh battery.
The gasket mount, combined with a flexible PC/PCB plate, is meant to give a soft, quieter, slightly bouncy typing feel. The south-facing RGB LEDs help lighting look clean even with aftermarket keycaps.
On Amazon.co.jp it was rated 4.7 out of 5 from 68 reviews, or 94% positive (as of October 6, 2026).
The rating is high, but the review count is still small, so treat it as a rough signal.
Compatibility Guide
| Item | Spec | What to check |
|---|---|---|
| Layout | Spanish ISO (75%, 82 keys) | OS keyboard settings and keycap compatibility |
| Connectivity | Bluetooth 5.1 / 2.4GHz / USB-C | Use 2.4GHz or wired for gaming |
| OS | Windows / macOS | Phones and tablets are not on the official list |
| Power and charging | USB-C | You can charge while using it wired |
| Dimensions | 35.8 × 16.3 × 5.6 cm (listed) | Depth, height and whether you need a wrist rest |
The layout row matters most. Compared with JIS or ANSI, the Spanish ISO layout differs in these ways:
- Enter is a tall, inverted-L key instead of the wide ANSI Enter
- Left Shift is shorter, with an extra "< >" key next to it
- There is an "Ñ" key, and the symbol legends follow the Spanish layout
- Right Alt works as AltGr, which you use to type symbols such as "@" and "#"
On Windows, set the OS keyboard layout to Spanish if you want each key to type what its legend shows. You can add a Japanese IME alongside it, so typing Japanese on a Spanish layout is possible.
However, the board has no JIS-specific keys such as Hankaku/Zenkaku, Henkan or Muhenkan. You switch input methods with the OS shortcut or by assigning keys in the IME settings.
If you leave the OS set to a JIS layout, many symbol keys will type something other than their legends.
macOS also has a Spanish input source, so the same approach works there. Both Windows and macOS are listed as supported, and you switch the keyboard's mode to match your OS.
Check the included manual for how to switch. iPads and Android phones often accept it as a standard Bluetooth keyboard, but the official OS list includes only Windows and macOS.
Treat mobile use as a bonus if it works, not as a guaranteed feature.
Pick the connection mode by task. Bluetooth 5.1 stores up to three devices, which suits typing on a PC, tablet and phone.
For gaming, use the 2.4GHz dongle or a USB-C cable.
Bluetooth generally adds more latency and is more likely to be unstable.
The listed dimensions are 35.8 × 16.3 × 5.6 cm.
That height is a bit large for a bare 75% keyboard, so these may be packaged dimensions. If you need it to fit a shelf or keyboard tray exactly, confirm the real dimensions on the product page or with the manufacturer.
Gasket-mount boards are often fairly tall, so add a wrist rest if your wrists end up raised.
Product Info
The EPOMAKER Ajazz AK820 PRO ISO-ES is a mid-range mechanical keyboard that launched in late 2024. It brings features you would expect on pricier boards, such as a TFT display and a gasket mount, to a more accessible price.
On Amazon.co.jp it was ¥20,052 as of October 6, 2026.
Prices change with sales and stock, so check the product page for the current price before you buy.
Key specifications:
| Item | Value |
|---|---|
| Layout | 75% (82 keys) |
| Connectivity | Bluetooth 5.1 / 2.4GHz / USB-C |
| Battery | 4000mAh |
| Display | 1.14-inch TFT color |

The box includes a USB-C cable, a 2.4GHz dongle, a keycap puller, a switch puller, a few spare switches and a manual.
The switch puller and spare switches suggest the board is built for switch swapping. The switch type (linear, tactile and so on) is not in our data, so check the product page to see which switches it ships with.
The manufacturer warranty is typically 1 year, but coverage can depend on the retailer.
Practical Points to Consider
Display and knob. The main benefit of the screen is that you can see the connection mode and status.
That is a small but real help on a three-device board, where it is easy to lose track of which device is active. The knob handles volume, which is handy if you play music or video while you work.
If you do not plan to customize what the screen shows, though, you may not notice much difference from a screenless board at the same price.
Battery. 4000mAh is a large battery for a wireless keyboard.
Actual runtime, however, depends heavily on RGB brightness and what the display is doing. If you want the battery to last, dim or turn off the lighting, use Bluetooth or 2.4GHz day to day, and charge over the cable when convenient.
Typing feel. The gasket mount and PC/PCB plate are designed to soften bottoming out.
If you like a crisp, stiff feel, this board may feel too soft. If you want it even quieter, you can swap in silent switches.
Recommended Users
- People who type in Spanish or already use ISO layouts. This is the main reason to choose this version. If you write Spanish every day, having Ñ and the AltGr symbols where the legends say is a real advantage.
- Multi-device users. Bluetooth switches among up to three devices, and 2.4GHz and wired modes are also available, so one keyboard can cover a work PC, a personal PC and a tablet.
- People who want more desk space. Without a numpad, the 75% layout is narrower and leaves more room for the mouse. The function row and arrow keys are still there for spreadsheets and coding.
- People who care about looks and typing feel. The screen, knob, RGB and gasket mount are all included, and you can customize the board further with new keycaps and switches.
It is not a good fit for heavy numpad users, such as people doing accounting data entry, or for anyone who depends on the JIS Henkan and Muhenkan keys for Japanese input.
Before You Buy
1. Choose the layout on purpose. This is the most important point.
If you want a compact keyboard with a screen but do not specifically need Spanish ISO, another layout version or another model will likely suit you better. If the OS layout does not match the legends, you will stop to think every time you type a symbol.
2. Keycap swaps need ISO-compatible sets. South-facing LEDs make keycap swaps attractive, but ISO uses a tall Enter, a short left Shift and an extra key.
A US-only keycap set will be missing these keys or have the wrong shapes. Look for sets labeled ISO-compatible or sold with an ISO kit.
3. In Japan, check for the Giteki mark before using wireless. Using Bluetooth or 2.4GHz devices in Japan generally requires Giteki certification.
Our data does not show whether this Spanish version has it. Check the product page and the markings on the keyboard or its box.
If you cannot confirm certification, plan to use it wired only.
4. Seller and warranty. On Amazon, this listing is sold and shipped by a marketplace seller (☆ショップANNIE☆), not by the manufacturer directly.
Defects and warranty claims may have to start with that seller. Before buying, check the seller's information to see where the 1-year warranty is handled.
5. Avoid Bluetooth for gaming. For FPS, rhythm games and other latency-sensitive games, use 2.4GHz or wired.
6. Read the reviews with care. A 4.7 rating is strong, but 68 reviews is still a small sample (as of October 6, 2026).
Amazon may also combine reviews from other variants, such as different layouts. When reading comments about the layout, check which version the reviewer bought.
7. Confirm the dimensions. As noted above, the listed size may include the packaging. Check the real dimensions if space is tight.
FAQ
Q. Can I type Japanese on it? A.
Yes. A Japanese IME works with any physical layout.
Because there are no JIS-specific keys such as Hankaku/Zenkaku, you switch input with a shortcut or a key you assign in the IME settings.
Q. Can I use US-layout keycaps? A.
Most keys will fit, but Enter, left Shift and the extra key next to it are ISO-specific. Choose an ISO-compatible keycap set.
Q. Does it work on a Mac? A.
macOS is listed as supported. Check the manual for how to switch modes, and set the macOS input source to a Spanish ISO layout so the keys match their legends.
Q. Is it good for gaming? A.
Over 2.4GHz or a wired connection, it is fine for typical gaming.
Bluetooth is prone to latency and is not recommended for games.
Q. Can I swap the switches? A.
A switch puller and spare switches are included, so the board is designed for switch swapping. Check the product page for the stock switch type and supported pin count.
