Epomaker TH33
Feature-Rich Comparison
- More functional 33-key layout includes arrow keys, Delete, Home, End, and other navigation keys.
- Larger 2000mAh rechargeable battery for extended wireless use.
- Features a 2-stage adjustable kickstand for three typing angles (6°, 8.9°, 12.3°).
- Larger and heavier at 380g, making it less portable.

Your primary need dictates the choice. If you want the smallest, lightest numpad possible to toss in a bag, the EK21 is the clear pick. If you need a desktop-centric tool with arrow keys, navigation cluster, and ergonomic adjustments for long sessions, the TH33's expanded layout and features justify its larger size and slightly higher cost.

What will you mostly use it for?
The TH33 is the more versatile choice for productivity-focused tasks like office work, programming, and content creation, thanks to its expanded key set and ergonomic adjustments. The EK21 wins for travel due to its notably smaller size and lighter weight. For gaming and modding, both are equally capable, sharing high-performance wireless, programmability, and a mod-friendly design.
It's a tie
- Both offer a 1000Hz polling rate in wired and 2.4GHz modes for responsive input.
- Both support N-key rollover for simultaneous key presses.
- Both are fully programmable via VIA for creating game-specific macros.

“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…”

“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 EK21 vs TH33: your questions
The core difference is the layout and size. The EK21 is a minimalist 20-key numpad with a knob, while the TH33 is a larger 33-key unit that adds a full arrow key cluster, navigation keys like Home and End, and an adjustable kickstand for ergonomic typing angles.
Yes, both numpads are fully programmable using the VIA software. This allows you to remap every key, create complex macros, and customize the functionality of the knob to suit your workflow or gaming needs.
The Epomaker TH33 has a larger 2000mAh battery, which should provide significantly longer wireless runtime compared to the 1000mAh battery in the EK21. This makes the TH33 better suited for extended cordless use.
Yes. Both the EK21 and TH33 feature hot-swappable PCBs that are compatible with most 3-pin and 5-pin MX-style mechanical switches. This allows for easy switch replacement without soldering.
According to its product description, the TH33 is designed with a layout that places numbers on the left and arrow keys on the right, which the manufacturer states caters to both left- and right-handed users. The EK21's symmetrical design is also ambidextrous.
Yes. Both the Epomaker EK21 and TH33 list Mac, Windows, and Android compatibility in their specifications, ensuring they will work across different operating systems.
The EK21 uses three layers: Poron bottom foam, sandwich foam, and an IXPE switch pad. The TH33 uses a five-layer system including Sandwich Latex, an IXPE Switch Pad, a PET sound enhancement pad, switch socket foam, and bottom foam for a dampened acoustic profile.
The TH33 specifically lists per-key adjustable RGB backlighting in its specifications. The EK21 description mentions dynamic RGB backlight but does not explicitly state per-key control, though VIA software may offer some customization.
The EK21 includes a 2-in-1 keycap/switch puller, an extra 'Back' keycap, a braided USB-C cable, and a 2.4GHz dongle. The TH33 includes a 2-in-1 puller, two extra switches, an extra backspace keycap, a USB-C cable, and a 2.4GHz dongle stored on the keyboard.
The TH33 is often cited by users as an excellent budget stream deck due to its 33 programmable keys and knob. Its larger key count provides more slots for shortcuts and macros compared to the EK21's 20 keys, making it more versatile for content creation and automation.
The TH33 features a 6-degree fixed angle with a 2-stage adjustable kickstand that provides two additional angles (8.9 and 12.3 degrees). The EK21 does not have a listed typing angle or an adjustable kickstand.
