What will you mostly use it for?
The TH99 is the clear choice for primary use as a gaming, office, or programming keyboard due to its complete key set and long battery life. The EK21 excels in portability for travel and offers more detailed modding features like VIA support and a flex-cut PC plate. For content creation, the choice hinges on whether a programmable knob or a full layout is more critical to your workflow.
Pick the Epomaker TH99
- The TH99 provides a full set of keys for game controls and macros.
- Its listed 2ms latency in wired mode is lower than the unspecified latency of the EK21.
- N-key rollover on a full layout is more practical for complex key combinations.

Epomaker EK21 vs TH99: your questions
No, the Epomaker EK21 is not a full keyboard. It is a dedicated 20-key numeric keypad with an additional aluminum knob. It is designed as an accessory to add a numpad to a setup that lacks one, such as with a tenkeyless or 65% keyboard.
Yes, the Epomaker TH99 is suitable for gaming. It features a 1000Hz polling rate, N-key rollover, and the manufacturer lists a 2ms latency in wired mode. Its full 96% layout provides all necessary keys for gaming and allows for macro programming through its software.
The TH99 has a significantly larger battery capacity at 4000mAh compared to the EK21's 1000mAh. According to the manufacturer, the TH99 can last up to 800 hours with the backlight off, while the EK21's runtime is not specified but will be considerably shorter.
Yes, both the Epomaker EK21 and TH99 feature hot-swappable sockets. They are compatible with both 3-pin and 5-pin mechanical switches, allowing you to easily change switches without soldering.
The EK21 offers deeper software customization as it supports VIA, an open-source, cross-platform remapping tool. The TH99 uses proprietary Epomaker driver software for programming. VIA is often preferred for its ease of use and lack of required installation.
No. According to the manufacturer's technical specifications for the TH99, it is explicitly listed as not compatible with PS4, PS5, or Nintendo Switch. It is compatible with Windows, Mac, and Android systems.
Both use a gasket mount for a softer typing experience. The EK21 uses a polycarbonate plate and has three foam layers. The TH99 uses a plastic plate but incorporates five sound-dampening layers, including a PET sheet, which may produce a deeper, more muted sound according to its description.
The TH99 is likely the quieter option for office use. It is available with silent linear switch options like the Sea Salt Silent Switch, and its five layers of dampening material are specifically designed to reduce noise. The EK21 uses standard linear switches.
The contents listed for the EK21 include the numpad, a 2-in-1 puller, an extra keycap, a USB cable, a wireless dongle, and a manual. A dedicated travel case is not mentioned in the provided specifications or description.
The EK21 uses Cherry profile keycaps. The TH99 uses Cherry profile for its ANSI layout and OEM profile for its ISO-DE layout. Both keyboards use PBT plastic for their keycaps, which are more resistant to shine than ABS.
Yes, both keyboards offer triple-mode connectivity. They can connect via a USB-C cable, a 2.4GHz wireless dongle, and Bluetooth. This allows you to pair them with multiple devices, such as a desktop PC and a laptop, and switch between them.
