Hot-swappable switches with customization options
The Royal Kludge RK84 features a robust hot-swappable switch system that allows users to easily replace switches without soldering. Enos Tech noted that the keyboard comes with RK-branded yellow switches, which are linear and offer a 45±10G actuation force, making them suitable for both gaming and typing. The keyboard includes a keycap and switch puller, along with four replacement switches, allowing for extensive customization. Enos Tech notes that other switch types are available beyond the yellow linear switches supplied, letting users tailor the board to different typing preferences and gaming styles. This flexibility is particularly appealing to enthusiasts who want to tailor their keyboard's feel and performance. The board supports both PCB-mounted and plate-mounted switches, providing further versatility for advanced users. The inclusion of multiple switch options and the ability to modify the keyboard's tactile response make the RK84 a standout choice for those seeking a customizable mechanical keyboard experience.
Three connectivity modes with Bluetooth 5.0
The RK84 supports three distinct connectivity modes: wired USB-C, 2.4GHz wireless, and Bluetooth 5.0. Tom's Hardware reported that while the wired and Bluetooth modes function reliably, the 2.4GHz wireless connection has limited range, approximately five feet, and is susceptible to interference from solid objects. The keyboard's Bluetooth 5.0 implementation compensates for these issues, offering a more stable wireless connection. According to SeerOfSouls, the keyboard can seamlessly connect to multiple devices including desktop computers, laptops, smartphones, and gaming consoles like the PS5. The power switch must be turned off to use the keyboard in wired mode, and users can toggle between Bluetooth and 2.4GHz modes using a physical switch on the keyboard. The RK84's ability to switch between devices without needing to disconnect and reconnect makes it a versatile option for users who work across multiple platforms. However, the limited range of the 2.4GHz wireless mode may pose challenges in larger workspaces or when obstacles block the signal path.
Battery life and power management
The RK84 is equipped with a substantial 3750mAh internal battery that provides extended usage time, particularly beneficial for users who frequently travel or work in environments without easy access to power outlets. Enos Tech highlighted that the keyboard's battery life is sufficient for long work sessions or weekend gaming marathons. The keyboard includes a USB-C port for charging the internal battery and two USB-A 2.0 passthrough ports for connecting other devices. According to SeerOfSouls, the battery capacity ensures that users can rely on the keyboard for extended periods without needing to recharge frequently. The keyboard also features a battery percentage indicator accessible via FN+Enter, which helps users monitor their power consumption. The RK84's power management system is designed to optimize battery usage across all connectivity modes, ensuring that users can maintain productivity without constant recharging. This feature is particularly valuable for users who prioritize portability and want a reliable keyboard that doesn't require frequent power management.
Compact 75% design with ergonomic enhancements
The RK84 follows a 75% compact layout, which excludes the numeric keypad but retains all essential keys, including a full row of function keys. The keyboard measures 12.5 x 5 x 1.75 inches and weighs 1.77 pounds, offering a solid build quality that feels substantial in hand. SeerOfSouls noted that the keyboard's design is simple yet effective, with a white plastic casing and black Royal Kludge logo. The keyboard includes two magnetic feet that elevate the rear of the keyboard by 0.375 inches, enhancing ergonomics and providing a more comfortable typing angle. Unlike some keyboards that require pop-out feet, the RK84's magnetic feet are easy to attach and remove, though they lack a dedicated storage spot, which may be inconvenient for travelers. The keycaps are ABS double-shot, featuring a cross pattern connector on the bottom, and are durable enough to withstand regular use. The compact design saves desktop space and makes the keyboard ideal for users with limited workspace or those who prefer a minimalist setup.
USB passthrough and additional features
One of the standout features of the RK84 is its USB passthrough functionality, which includes two USB-A 2.0 ports. These ports allow users to connect additional devices such as USB sticks, wired mice, or charging cables directly to the keyboard. Enos Tech emphasized that this feature adds significant value by reducing the number of cables needed and providing convenient access to power and data. The keyboard also includes secondary function keys that can be activated by holding the FN key, enabling users to control volume, open emails, and access other functions quickly. The RK84 supports both Windows and Mac operating systems, as well as Android/Chromebook and iOS, making it compatible with a wide range of devices. However, the keyboard does not include keycaps specifically designed for Mac or iOS, which may require users to adapt to using the Windows key for command functions. This limitation is a minor inconvenience for users who primarily use Apple devices but does not significantly impact overall usability.
Signal reliability in wireless modes
Tom's Hardware specifically noted that the 2.4GHz connection has limited range, approximately five feet, and is prone to interference from solid objects. This limitation can cause signal instability in environments with multiple wireless devices or physical barriers. The keyboard's Bluetooth 5.0 implementation, however, provides a more stable and reliable wireless connection, compensating for the shortcomings of the 2.4GHz mode. SeerOfSouls reported that despite the range limitations, the keyboard's Bluetooth connection remains consistent and functional across various devices. Users who primarily rely on 2.4GHz wireless may experience connectivity issues in larger workspaces or when positioned away from the receiver. For those who prefer a more stable wireless experience, the Bluetooth option is recommended, though it requires a slightly more complex setup process compared to the 2.4GHz mode.
Build quality and user experience
The build quality of the RK84 is described as solid and substantial, with a white plastic casing and black Royal Kludge branding that gives the keyboard a clean, modern appearance. Enos Tech noted that the keyboard feels robust and well-constructed, with attention to detail in the manufacturing process. The keycaps are ABS double-shot, featuring a cross pattern connector on the bottom, which ensures durability and prevents wear over time. The keyboard's weight of 1.77 pounds contributes to its stability during use, reducing the likelihood of movement or sliding during intense gaming sessions. SeerOfSouls highlighted that the keyboard's design is simple yet effective, with a focus on functionality rather than flashy aesthetics. The magnetic feet provide a convenient way to adjust the keyboard's angle, though they lack a dedicated storage spot, which may be inconvenient for users who travel frequently. Overall, the build quality and user experience are praised for their reliability and practicality, making the RK84 a solid choice for users who value both performance and durability.
