Epomaker TH40
40% Compact Keyboard Choice
- Ultra-compact 40% layout and 500g weight offer maximum portability.
- Supports both QMK and VIA for extensive firmware programmability.
- Split spacebar layout with an integrated FN key can improve typing ergonomics.

Your primary need dictates the choice. If you work primarily at a single desk, value a number pad, and want tactile controls like a knob, the Epomaker QK108 is the logical pick. If your priority is a keyboard that can disappear into a bag, you're comfortable with layers, and you value deep firmware tinkering, the Epomaker TH40's compact form is compelling. Consider how often you truly need dedicated keys versus a minimalist setup.

“A nice Full sized mechanical keyboard under 100$ is a good deal and it's type experience is really good.”
“Working so I sent it to place to fix it and they quoted me something crazy but the other keyboard I ordered still works I do not understand why it stopped working”

“Overall good little keyboard for the price, other 40s cost more but better quality, also I could not find a few characters mapped on this one, not in manual or online.”
“The keyboard is very solid ooverall, but frequently will type two letters instead of one on key press. This is a very frustrating issue and leads to many typos. Without this problem, it would easily be a 5-star keyboard.”

Epomaker QK108 vs TH40: your questions
The Epomaker QK108 has a significantly larger 8000mAh battery compared to the TH40's 3000mAh battery. According to the QK108's vendor page, this can provide up to 229 hours of use with RGB and the screen turned off.
Yes, but it requires adaptation. The TH40 lacks dedicated arrow keys, so you must program a function layer to access them. This is done through the VIA or QMK software, but it adds a step compared to a keyboard with dedicated arrows.
Yes, both the Epomaker QK108 and TH40 feature hot-swappable sockets. The QK108 listing specifies 5-pin sockets, while the TH40 listing mentions support for 3-pin and 5-pin switches.
It depends on your preference. The QK108 provides immediate access to symbols and a number row on its main layer. The TH40 requires heavy use of layers but offers greater customization through QMK/VIA for creating powerful shortcuts, making it a tie for different styles.
Yes. The Epomaker QK108 vendor description states compatibility with Mac, Windows, and Linux. It also includes dedicated Mac modifier keycaps in the box for swapping out the Windows keys.
The TH40 is programmable using VIA software and also supports QMK. You need to download the correct JSON configuration file from Epomaker's website and use it within the VIA application to remap keys and create macros.
According to its listing, the QK108 comes with the keyboard, a detachable USB A-to-C cable, a 2.4GHz wireless receiver, a 2-in-1 switch and keycap puller, a manual, three additional Mac keycaps, and two additional switches.
No. The Epomaker TH40 does not have a control knob or an LED screen. Its ultra-compact 40% design focuses on minimizing its footprint, so it forgoes these multimedia features found on the larger QK108.
Both keyboards use PBT keycaps in a Cherry profile, which are more durable and resistant to shine than ABS. The QK108's listing further specifies that its keycaps use a dye-sub printing technique.
The Epomaker QK108 is described as having a more complex, five-layer sound dampening design including sandwich foam, an IXPE switch pad, a PET sheet, and bottom silicone. The TH40 uses Poron and IXPE foams, but the QK108's vendor page emphasizes its multi-layered 'sound-improvement formula'.
Yes, both offer tri-mode connectivity (wired, 2.4GHz, Bluetooth). The QK108 vendor page specifies it can pair with and remember up to five devices simultaneously across its different connection modes.
