- Extensive programmability via VIA software for key remapping and macros.
- Gasket mount structure with multiple internal foam layers for sound dampening.
- 33-key layout includes a programmable knob, arrow keys, and navigation cluster.
- ABS plastic case may feel less premium than other materials.
- More complex layout may have a larger footprint than a standard numpad.
- North-facing RGB on the YZ21 is not a con for the TH33, but the TH33's south-facing LEDs are a specific design choice that prevents interference with certain keycap profiles.
Get the
Yunzii YZ21 Numpad
- Simpler, potentially more compact 21-key numpad layout.
- Hot-swappable PCB supports 3-pin and 5-pin switches.
- Offers tri-mode connectivity (Bluetooth, 2.4GHz, wired).
- Lacks advanced programmability software like VIA or QMK support.
- Plate mount design may offer a different typing feel compared to gasket mounts.
- Smaller 1500mAh battery compared to the TH33's 2000mAh.
For most users, the Epomaker TH33 is the recommended choice. Its superior programmability, additional keys, and gasket-mounted design provide significantly more value and versatility for a similar price. Only consider the Yunzii YZ21 if you strictly need a basic, no-frills wireless numpad and find it available at a notably lower cost.

What will you mostly use it for?
The Epomaker TH33 is the more versatile choice, winning in scenarios demanding high programmability, extra keys, or a premium typing feel. Its advantages in gaming, office work, programming, and content creation stem from its VIA support, knob, and expanded layout. The Yunzii YZ21 may appeal for basic numeric entry and travel due to its potentially simpler and more compact form factor, but it lacks the advanced features of its competitor.
Pick the Epomaker TH33
- The TH33 has a specified 1000Hz polling rate for wired and 2.4GHz modes, which the YZ21's listing does not mention.
- Its VIA software support allows for complex macro programming for in-game actions.
- The layout includes arrow keys and function keys useful for gaming shortcuts.

“Wow, at first I thought it was gonna be useless because I don't use arrows nor numpad, that's why I use only 60% keyboard. When I recieved the TH33 I noticed that I can remap every single button. Now I use it as a budget stream deck, I put on matching keycaps…”
“It was what I wanted but the usability was not as good as I wanted. Software was very buggy and there are almost no alternative keycap options.”

Epomaker TH33 vs Yunzii YZ21 Numpad: your questions
The Epomaker TH33 has 33 keys, while the Yunzii YZ21 has 21 keys. The TH33 includes extra keys like arrows, delete, page up/down, and a programmable knob, making it more than just a numeric keypad.
The Epomaker TH33 supports full key remapping and macro creation through VIA software, as stated by the manufacturer. The Yunzii YZ21 listing mentions customizable RGB software but does not specify key remapping capabilities, suggesting its programmability is more limited.
The Epomaker TH33 uses a gasket mount, where the plate is suspended on rubber gaskets to absorb typing vibrations and create a softer, more consistent feel. The Yunzii YZ21 uses a plate mount, where the plate is fixed directly to the case, typically resulting in a firmer typing experience.
Yes, both the Epomaker TH33 and Yunzii YZ21 product listings specify compatibility with Mac and Windows operating systems.
The Epomaker TH33 is equipped with a 2000mAh battery, while the Yunzii YZ21 has a 1500mAh battery. Based on capacity alone, the TH33 has the potential for longer use between charges, though actual battery life depends on usage patterns and RGB settings.
Yes, both the Epomaker TH33 and Yunzii YZ21 feature hot-swappable PCBs that support both 3-pin and 5-pin mechanical switches, allowing you to change switches without soldering.
The Epomaker TH33 uses Cherry-profile dye-sublimated PBT keycaps. The Yunzii YZ21 uses XDA-profile dye-sublimated PBT keycaps. XDA is a uniform, spherical profile, while Cherry has sculpted rows.
According to Epomaker's specifications, the TH33 has a 1000Hz polling rate when used in wired or 2.4GHz wireless mode, and 125Hz when using Bluetooth. The Yunzii YZ21 listing does not provide a polling rate specification.
The Epomaker TH33 has south-facing RGB LEDs. This orientation prevents the LED housing from interfering with the lower profile of Cherry-style keycaps, making it the better choice if you plan to use such keycaps.
The Epomaker TH33 includes a USB cable, 2.4GHz receiver, a 2-in-1 keycap/switch puller, two extra switches, and an extra backspace keycap. The contents for the Yunzii YZ21 are not detailed in the provided listing.
Yes. The TH33's VIA software support allows you to remap every key to any function or complex macro. User reviews specifically mention using it as a budget stream deck for controlling streaming software or other applications.
