Frequently Asked Questions
Q: What is a gasket structure and why does it matter on the RK H81 mechanical keyboard?
A: A gasket structure suspends the keyboard's PCB and switch plate between silicone gaskets rather than screwing it rigidly to the case. This creates a slight flex and cushioning effect when you type, resulting in a softer, more comfortable keystroke feel and a deeper, more pleasing sound compared to traditional tray-mount or top-mount keyboards. It is a feature typically found on premium custom keyboards, making the RK H81 stand out in its price class.
Q: Can I use the RK H81 with multiple devices at the same time?
A: The RK H81 supports tri-mode connectivity — Bluetooth 5.0, 2.4 GHz wireless, and USB-C wired — allowing you to connect to different devices. You can pair via Bluetooth with one device, use the 2.4 GHz dongle with another, and switch between them quickly. It is compatible with Windows, macOS, Android, and iOS devices.
Q: Do I need soldering tools to swap switches on the RK H81?
A: No soldering is needed. The RK H81 features a hot-swappable PCB that accepts both 3-pin and 5-pin switches. Simply use the included 2-in-1 keycap and switch puller to remove a switch and press in a new one. This makes it easy to experiment with different RK switch types — Red, Blue, Brown, or Skycyan — without any specialized tools.
Q: How long does the battery last on the RK H81?
A: The 3,750 mAh battery provides up to 200 hours of continuous use when the RGB backlighting is turned off. With backlighting enabled, battery life will vary depending on the brightness and mode selected. A full charge takes approximately 6–7 hours via the included USB-C cable.
