Epomaker QK108 vs RT85Full-Size vs 75% Layout Comparison

According to their respective technical specifications, the Epomaker QK108 lists lower latency. It claims 3ms in wired mode and 5ms in 2.4GHz wireless mode. The RT85 lists 6ms wired and 12ms in 2.4GHz mode. Both offer a 1000Hz polling rate in their wired and 2.4GHz modes.

Yes, but they use different software. The QK108 supports VIA, an open-source, cross-platform remapping tool. The RT85 uses Epomaker's proprietary Driver 3.0 software for key remapping and macro recording on Windows and Mac systems.

Yes, both the QK108 and RT85 are listed as compatible with Mac and Windows. The QK108 specifically includes additional Mac modifier keycaps (Command, Option) in the box to match the macOS layout.

Both keyboards feature a large 8000mAh battery. Battery life varies with usage. The QK108 vendor lists up to 229 hours with RGB and screen off. The RT85 vendor lists up to 320 hours with RGB and screen off, and 90 hours with the screen on.

Both use PBT keycaps for durability. The QK108 uses dye-sublimated Cherry profile keycaps. The RT85 uses double-shot PBT keycaps in a Cherry profile, which typically offers more durable legends that won't wear off.

Yes, both keyboards feature hot-swappable 5-pin sockets. This allows you to easily change the mechanical switches without soldering. Each keyboard includes a 2-in-1 switch and keycap puller in the box.

The RT85's joystick is a 4-directional control plus a press, defaulting to volume up/down, RGB effect toggle, and mute. The QK108 has a rotary knob, which is typically programmable for scrolling or adjusting values like volume. The knob offers infinite rotation, while the joystick provides directional inputs.

Both use gasket mount designs and Cherry profile keycaps for a comfortable feel. The RT85 specifically mentions a flex-cut polycarbonate plate and an ergonomic design with a wrist-friendly angle. The QK108 has a 2-stage adjustable kickstand for three typing angles (6, 8.5, 11.5 degrees).

The QK108 uses a 5-layer system including sandwich latex foam, an IXPE switch pad, a PET sound enhancement pad, bottom sponge, and bottom silicone. The RT85 also uses a 5-layer system with PORON sandwich foam, IXPE switch pad, PET pad, EPDM switch socket foam, and a silicone base.

No, the Epomaker RT85 has a 75% layout. This means it omits the number pad and the function key row to save space. The number row is still present above the letter keys, but a dedicated number pad is not included.

The QK108 includes the keyboard, a detachable USB A-to-C cable, a 2.4GHz wireless receiver, a 2-in-1 puller, a manual, three additional Mac keycaps, and two additional switches.

Yes, because both are hot-swappable. They support standard 5-pin mechanical switches. You can install aftermarket linear, tactile, or silent switches, provided they have a 5-pin design, to customize the typing feel and sound.
