Bottom line

Your primary need dictates the choice. If your desk is small, you travel, or you prioritize a lighter build with some metal, the Ajazz AK820 Pro is the clear pick.

Best for

What will you mostly use it for?

The AK870 Plus is the stronger choice for stationary, productivity-focused tasks like office work, programming, and content creation, thanks to its larger layout and exceptional battery life. The AK820 Pro excels in space-constrained environments, for gaming, and for travel due to its compact form factor and lighter weight. For keyboard modders, both offer a similarly capable foundation with gasket mounts and hot-swap sockets.

Pick the Ajazz AK820 Pro

  • The AK820 Pro's 1kHz polling rate in wired and 2.4GHz modes is explicitly stated for responsive gameplay.
  • Its lighter weight (810g) and more compact 75% layout free up more desk space for mouse movement.
  • The vendor description notes N-Key Rollover (NKRO) support for simultaneous key presses.
