Compare Epomaker EK21 vs TH99 Pro Differences Side by Side

This comparison is for users deciding between expanding their setup with a dedicated numpad or replacing their main keyboard with a compact all-in-one solution. The choice is difficult because both are Epomaker products with gasket mounts, triple-mode connectivity, and hot-swappable switches, but serve fundamentally different purposes. The EK21 is a 20-key accessory, while the TH99 Pro is a 98-key primary keyboard with a screen and massive battery.

Pros and Trade-offs

Select the Epomaker TH99 Pro if you are looking for a versatile, primary keyboard that saves desk space without sacrificing a numpad. Choose the Epomaker EK21 only if you already have a compact keyboard you love and specifically need a portable, programmable number pad to complement it. They are designed for completely different roles on your desk.

Epomaker EK21

  • +Extremely portable at 200g with a compact 20-key numpad layout.
  • +Officially supports VIA software for open-source key remapping and macro programming.
  • +Includes a braided USB-C cable and a 2.4GHz dongle in the box.
  • +Gasket mount structure with Poron bottom foam, sandwich foam, and an IXPE switch pad for sound dampening.
  • −Is only a numpad, not a standalone keyboard for typing.
  • −Smaller 1000mAh battery requires more frequent charging than the TH99 Pro.
  • −Some user reviews mention firmware or software issues with VIA configuration.

  • +Massive 10,000mAh battery promises weeks of use on a single charge with RGB off.

  • −Uses proprietary Chrome-based software instead of open-source VIA.
  • −More expensive than the EK21, reflecting its role as a primary keyboard.

Which Keyboard Is Better for Your Needs?

The TH99 Pro is the clear choice as a primary keyboard for gaming, office work, programming, and content creation due to its complete key set, long battery life, and integrated screen. The EK21 wins for travel and has an edge for modders due to its VIA support, but it functions strictly as a supplemental numpad. Your decision hinges entirely on whether you need a new main keyboard or a specialized accessory.
