What will you mostly use it for?
The Ajazz AK35i V3 is the clear choice for traditional office work, gaming, and content creation where its full layout, knob, and screen provide tangible benefits. The Epomaker TH40 excels in portable and specialized scenarios like travel and programming, where its small size and VIA programmability are major assets. For hardware modders, the TH40's documented foam layers and open firmware support offer more tinkering potential.
Pick the Ajazz AK35i V3
- Full 104-key layout includes dedicated arrow keys and function row for immediate access.

Ajazz AK35i V3 vs Epomaker TH40: your questions
The Ajazz AK35i V3 has a significantly larger 8000mAh battery compared to the Epomaker TH40's 3000mAh battery. The Ajazz vendor claims up to 140 hours of use with RGB off, suggesting it will last much longer between charges under similar conditions.
The vendor description for the Ajazz AK35i V3 does not mention support for VIA, QMK, or other key remapping software. Its customization appears focused on the TFT screen content and RGB lighting effects, not on reassigning key functions.
Typing on the TH40 requires memorization, as its 40% layout lacks many standard keys. You must use function layers to access numbers, symbols, and arrow keys. This can be efficient once learned but has a steep initial learning curve for touch typists.
Yes, the Ajazz AK35i V3 includes a dedicated multimedia metallic knob, which the vendor states can be used to adjust volume.
According to Epomaker's technical specifications, the TH40 has a 1000Hz polling rate when used in wired or 2.4GHz wireless mode. Its Bluetooth mode operates at a 125Hz polling rate.
The Epomaker TH40 is far more portable. It weighs only 500g and measures 258 x 97 mm, compared to the Ajazz AK35i V3 at 1230g and 448 x 148 mm. The TH40's 40% size is designed to be easily packed in a bag.
Yes, both the Ajazz AK35i V3 and the Epomaker TH40 feature hot-swappable sockets, allowing you to change mechanical switches without soldering. The TH40's PCB supports both 3-pin and 5-pin switches.
The Ajazz AK35i V3 features a 1.14-inch TFT color display screen. The vendor states it can show time, connection status, and battery level by default, and can be customized with static images or animated GIFs.
Epomaker's specifications list compatibility with Windows and Mac. However, some user reviews mention difficulties with VIA software or firmware updates on macOS, suggesting potential software hurdles despite hardware compatibility.
Both use gasket mounts and internal foam. The Ajazz description mentions a five-layered structure with Sandwich PORON Cotton, IXPE, and silicone. The Epomaker description specifies Poron plate foam, an IXPE switch pad, and bottom Poron foam. Both are well-damped, but the Ajazz may have a more complex foam stack.
A split spacebar divides the standard long space key into two or three separate keys. The Epomaker TH40 has a split spacebar, with a 2.25u and a 2.75u section separated by an FN key. This allows the extra keys to be programmed for different functions.
