The TH40 keyboard from Epomaker is a compact, lightweight, and fun-to-use peripheral that is aimed at gamers who need an ultra-portable device. Although the possibilities are endless, I think this keyboard will appeal to the handheld gaming market. People with Steam Decks and the Legion Go will adore this minute accessory.
Although it is small, it is mighty powerful. It offers an exceptional 3000 mAh battery, impressive polling, tri-mode connectivity, and amazing build quality. Alongside this, it is fully customisable using VIA programming. This will appeal to hardcore gamers and those who adore profiles for specific genres.

- The packaging is small, interesting, and recyclable.
- The TH40 keyboard is an easy-to-handle, 44-key device. It has a rear tactile switch for connectivity, a handy carry loop, and it is available in 2 colourways.
- A USB-C cable and spare items are provided.
- Learn the basics with the user manual.




Technical aspects.
My idea that the TH40 keyboard is aimed towards the mobile gaming market is pretty sound. Consequently, it must tick several boxes to be suitable. Tri-mode connectivity, a phenomenal battery, and macro inputs are a must. Luckily, it incorporates each of these in its tiny case.
Connecting this device is a cinch. There is a USB-A transmitter, a USB-C cable, or 3x Bluetooth profiles. The latter is the most convenient for mobile gaming. Swapping between profiles was easy, and the stable connection offers a low power draw and up to 125 Hz polling. If you use the USB cable or the transmitter, the polling jumps to 1000 Hz. This is ideal for competitive gaming.
The impressive battery lasts around 2 weeks between charges. This drops considerably if you turn up the RGB lighting. However, if power over fashion is a must, you can switch off the south-facing RGB and maximise your gaming time. Charging the device takes no time, and you can charge it while gaming.
VIA programming may seem alien to some, but I love it. Changing your profiles, adjusting your lighting, fiddling with your macros, and much more can be achieved through the free-to-download software. This straightforward tool builds technical know-how, and inexperienced gamers can quickly enhance their confidence with gaming peripherals.


Build quality.
The TH40 keyboard is a 40% form factor device offering a minuscule 44 keys. This may seem inferior to other Epomaker devices, but it is perfect for its niche market. The VIA and macro design ensure that you have full input use. Yes, it takes a little trial and error, but practice makes perfect.
This keyboard offers hot-swappable 3/5-pin switches. This wasn’t essential for me, but lovers of specific gaming switches will appreciate the simple process. The Cherry profile keycaps are durable thanks to the double-shot PBT material. If you wish to remove them, this can be done using the provided pulling tool.
The device weighs 500g and the case is made from a hardened plastic. This makes it extremely durable. This is a must, as this portable peripheral will be chucked into your bag. Thankfully, it’ll resist unwanted wear and tear and the normal grime of everyday commuting.
Finally, the multilayer internal components deliver a pleasant soundscape. There is a traditional thwock of the mechanical switches, and this was fantastic. However, the noise isn’t obnoxious despite its deliberately blunt ways.


Is the TH40 keyboard worth it?
The TH40 keyboard offers a massively convenient approach with a slight learning curve. The programmable inputs are fantastic, but you must be prepared to put the work in. As such, it isn’t as plug-and-play as other Epomaker products. This wasn’t an issue, as I like macro profiles and the exceptionally small design. Additionally, it is ideal for my Steam Deck. Accordingly, I think it’s amazing, and I recommend buying it here!
