What will you mostly use it for?
The RT82 is the clear choice as a primary keyboard for gaming, office work, and programming due to its complete 75% layout.

For modding, both offer equivalent hot-swap and software support, making it a tie based on personal project goals.
Pick the Epomaker RT82

“I love the sound, the keyboard was shipped fast, but i have found some of the keys have input issues at times where it doesn't register the key being pushed”
“I received an informative sms two months ago that the keyboard is arriving, It has still not arrived.”

“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 RT82 vs TH33: your questions
No, the TH33 is a 33-key numpad and macro pad. It lacks alphanumeric keys, so it must be paired with a separate primary keyboard for general typing tasks. Its vendor description positions it as a companion device for numeric input, arrow keys, and programmable shortcuts.
According to Epomaker, the RT82's 1.14-inch LCD screen can show the date, time, and keyboard battery level. It also supports a typewriter mode that displays typed letters and can cycle through up to three saved GIFs for personalization. The screen is magnetically detachable.
Yes, both the RT82 and TH33 list Mac and Windows compatibility in their specifications. The RT82 also includes three additional keycaps specifically for Mac layout in the box.
The RT82 has a larger 4000mAh battery compared to the TH33's 2000mAh. Epomaker provides detailed estimates for the RT82, ranging from 14 hours with RGB and screen on, to 115 hours with both off. The TH33's exact battery life is not specified, but its smaller capacity suggests shorter runtimes.
Yes, both the RT82 and TH33 feature hot-swappable printed circuit boards. They are both compatible with most 3-pin and 5-pin mechanical switches, allowing you to easily change the typing feel without soldering.
Both keyboards support VIA, a web-based and desktop software that allows for key remapping, macro creation, and lighting customization without needing to flash firmware. Both product listings include links to their respective JSON configuration files for VIA.
Both keyboards list the same latency figures in their technical specs: 3ms in wired mode, 5ms in 2.4GHz wireless mode, and 15ms in Bluetooth mode. Both also have a 1000 Hz polling rate in wired and 2.4GHz modes.
The RT82 uses a five-layer system with Sandwich Latex, an IXPE switch pad, a PET sound-enhancement pad, bottom foam, and bottom silicone. The TH33 uses a similar set of layers: Sandwich Latex, IXPE Switch Pad, PET Sound Enhancement Pad, Switch Socket Foam, and Bottom Foam.
Both offer adjustable typing angles via a two-stage kickstand. The RT82 offers angles of 5, 7.5, and 11 degrees, while the TH33 offers 6, 8.9, and 12.3 degrees. Both use Cherry profile keycaps which are sculpted to follow finger curvature.
The RT82 includes the keyboard, detachable screen, USB-C cable, 2.4GHz receiver, switch/keycap puller, manual, 3 Mac keycaps, and 2 extra switches. The TH33 includes the numpad, 2.4GHz receiver, USB-C cable, puller, 2 extra switches, a backspace keycap, manual, and product card.
Yes, the Epomaker TH33 features a smart programmable knob. This knob can be remapped in VIA software to control volume, scroll, or application-specific parameters, which is a key feature not present on the RT82.
