DOIO KB03 04 vs Epomaker TH333-Key Macro Pad vs 33-Key Numpad

The core difference is their form and function. The DOIO KB0304 is a 3-key macro pad designed primarily for assigning shortcuts or macros, featuring a distinctive RGB light ring. The Epomaker TH33 is a 33-key wireless numpad that includes a full number pad, arrow keys, function keys, and a programmable knob, making it a productivity-focused expansion pad.

Yes. The Epomaker TH33 supports tri-mode connectivity, including Bluetooth 5.0, a 2.4GHz wireless connection with a dedicated receiver, and a USB-C wired connection. The manufacturer lists a 2000mAh battery to power the wireless modes.

No. The DOIO KB0304 is a wired-only device that connects via its included USB Type-C cable. There is no mention of a battery or wireless capability in its specifications or vendor description.

Both are programmable via VIA software, allowing you to remap keys. The Epomaker TH33 offers more physical keys (33 vs. 3), giving you far more capacity for shortcuts, layers, and complex macros. The TH33 also has a knob that can be programmed for actions like scrolling.

Yes. Both the DOIO KB0304 and the Epomaker TH33 feature hot-swappable sockets. The manufacturer for each states compatibility with most 3-pin and 5-pin MX-style mechanical switches, allowing for easy switch replacement without soldering.

Yes. According to the technical specifications provided by Epomaker, the TH33 is compatible with Mac, Windows, and Android operating systems.

The vendor description for the DOIO KB0304 states the upper part is a 5.6cm diameter soft light display stand. It features full-color RGB lighting with adjustable effects, colors, and brightness, which can be customized alongside the key functions.

According to Epomaker's listing, the TH33 comes with a wireless 2.4GHz receiver stored on the keyboard, a USB A to C cable, a 2-in-1 keycap and switch puller, two extra switches, an extra backspace keycap, and product manuals.

The DOIO KB0304 is significantly more portable. It weighs 205g and measures 23 x 78 x 104 mm, making it much smaller and lighter than the 380g Epomaker TH33, which measures 45 x 151 x 141 mm.

The Epomaker TH33 is designed for a tuned sound and feel. It uses a gasket mounting structure and includes multiple internal sound-dampening layers such as sandwich latex, an IXPE switch pad, a PET film, and foams to reduce noise. It comes with factory-lubed linear switches and PBT keycaps.

Not effectively. With only three keys, the DOIO KB0304 cannot function as a traditional numpad. You could program the keys to input numbers, but you would be limited to just three digits or would need to use layers, making data entry impractical compared to a dedicated numpad like the TH33.
