What will you mostly use it for?
The TH108 is the clear choice for traditional office work and content creation where a full layout is non-negotiable. The EK21 dominates for travel and offers superior firmware-level modding potential with VIA. For gaming and programming, the choice is a draw, hinging on whether you value a dedicated macro pad (EK21) or an all-in-one board (TH108).
It's a tie
- Both offer a 1000Hz polling rate in wired and 2.4GHz modes for low latency.
- Both support N-key rollover for anti-ghosting.
- The TH108's full layout provides dedicated macro keys, while the EK21 can be programmed as a dedicated macro pad via VIA.

“Great wireless connectivity, sounds and feels as good as my 200$ custom keyboard. Great buy especially with the discount, would definitely buy again.”
“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…”

“My first mechanical keyboard. A lot of people like the clack of some keyboards. I prefer the silent switches. This keyboard is great and works very well.”
“Its very cool, I just wish I had picked the silent switch version instead. :/”

Epomaker EK21 vs TH108: your questions
No, the Epomaker EK21 is a 20-key numeric keypad. It is designed as a companion device to add a numpad or macro keys to a compact keyboard setup. You will need a separate main keyboard for letter keys and standard modifiers.
The Epomaker TH108 has a significantly larger 8000mAh battery compared to the EK21's 1000mAh battery. According to the manufacturer, the TH108 offers up to 160 hours of wireless use, making its battery life far superior for a standalone wireless keyboard.
Yes, but the method differs. The EK21 supports full programming via the open-source VIA software. The TH108 uses a proprietary web-based driver for key remapping and macro creation, which the manufacturer states is available for units purchased after September 2025.
Yes. Both the Epomaker EK21 and TH108 feature hot-swappable PCBs. The EK21 is compatible with 3-pin and 5-pin mechanical switches, while the TH108 is compatible with 5-pin mechanical switches.
The Epomaker TH108 is the better choice for a quiet office. It offers a pre-lubed silent linear switch option (Sea Salt Silent) and has five layers of internal sound dampening, including silicone, to reduce typing noise. The EK21, while also foam-dampened, uses standard linear switches.
The product specifications and vendor description for the Epomaker TH108 do not mention a USB hub or passthrough port. It includes a USB-C port for charging and wired connectivity only.
The EK21 comes with the numpad itself, a 2-in-1 keycap and switch puller, an extra 'Back' keycap, a 1.8-meter detachable braided USB A-to-C cable, a 2.4GHz wireless dongle, and a multilingual manual.
The Epomaker TH108 features a two-stage adjustable kickstand. According to its technical specifications, this provides three typing angles: 6, 8, and 10.5 degrees.
Yes, the manufacturer's description for the EK21 states the aluminum alloy knob can be used for volume adjustment. Furthermore, because the EK21 supports VIA software, the knob's function can be fully customized to other actions as well.
The Epomaker EK21 is more beginner-friendly for firmware and functional modding due to its VIA support, which has a large community and straightforward interface. For physical mods like switch and keycap changes, both are equally accessible due to their hot-swap sockets.
The keycaps differ. The TH108 uses double-shot PBT keycaps, as stated in its specifications. The EK21 uses dye-sublimated PBT keycaps. Double-shot legends typically offer better durability against wear.
According to the Epomaker TH108's technical specifications, its latency is 5ms in 2.4GHz wireless mode and 11ms in Bluetooth mode. The EK21's product page does not specify wireless latency values.
