What will you mostly use it for?
The QK108 is the clear choice for primary desktop use across gaming, office work, programming, and content creation due to its complete key set, extensive battery, and unique screen. The EK21 wins for travel and as a secondary device, where its tiny form factor as a numpad is its defining advantage. For modding enthusiasts, both offer a nearly identical foundation of hot-swap sockets and VIA support, making them equally viable platforms for customization.
Pick the Epomaker QK108
- The QK108's full layout provides dedicated macro keys without layer switching.
- Its listed 3ms wired and 5ms 2.4GHz wireless latency may offer a slight edge for competitive play.
- South-facing RGB LEDs are listed as a feature, which can improve compatibility with certain keycap profiles.

“I have had this thing for years, I have updated to every Json file and firmware file I can find and it has NEVER worked right, Either the Json file or the firmware is jacked up and no one at Epomaker can give me any explanation. This numpad is the reason I…”

Epomaker EK21 vs QK108: your questions
No, the Epomaker EK21 is not a full keyboard. It is a 20-key numeric keypad, or numpad, designed to provide dedicated number and calculation keys. It must be used alongside a separate main keyboard for typing letters and standard functions.
According to Epomaker's specifications, the QK108 has a large 8000mAh battery. The listed battery life varies from 28 hours with RGB and screen on, up to 229 hours with both RGB and the screen turned off. Actual usage will depend on lighting settings and connection mode.
Yes. The Epomaker EK21 supports triple-mode connectivity, including Bluetooth and 2.4GHz wireless. You can pair it via Bluetooth or use the included USB dongle for a 2.4GHz connection, making it compatible with laptops, tablets, and PCs that lack a dedicated numpad.
Yes, both the EK21 and QK108 are listed as compatible with Mac and Windows. The QK108 specifically includes additional Mac modifier keycaps (Command, Option) in the box to replace the standard Windows keys for a native Mac layout.
VIA is open-source software that allows deep keyboard customization. Both the EK21 and QK108 support VIA, letting you remap any key, create complex macros, and adjust the functionality of the control knob directly from a graphical interface without flashing firmware.
Yes, both keyboards feature 5-pin hot-swappable sockets. This means you can easily remove the included mechanical switches and install new compatible switches without any soldering, using the included 2-in-1 puller tool.
Both keyboards come with PBT keycaps using a dye-sub printing technique, which makes the legends durable and resistant to shine. They both also use a Cherry profile, which is a mid-height profile favored for typing comfort.
Gasket mount is a design where the plate holding the switches is suspended on rubber or silicone gaskets inside the case. This isolates typing vibrations for a softer, more cushioned feel and can reduce noise. The EK21 uses this with Poron foam, while the QK108 uses a five-layer sound-dampening design.
The QK108's mini LED screen is customizable. According to Epomaker, you can use their provided Image Tool to upload custom animated GIFs or images to the screen, in addition to displaying information like battery level, date, and time.
The Epomaker EK21 is vastly better for a small desk due to its tiny 20-key footprint. It can be stored easily when not in use. The QK108 is a full-size keyboard measuring 439mm wide, which requires significant permanent desk space.
The EK21 includes the numpad, a 2-in-1 puller, an extra 'Back' keycap, a braided USB-C cable, a 2.4GHz dongle, and a manual. The QK108 includes the keyboard, a USB-C cable, a 2.4GHz dongle, a 2-in-1 puller, a manual, three Mac keycaps, and two additional switches.
