Keydous NJ81

The Keydous NJ81 is a compact 80-key mechanical keyboard suited for users who want a versatile, portable layout with wireless and wired connectivity. It fits well for typists and hobbyists who value switch customization and programmable keys, as well as those needing multi-device support. Its unique display screen and hot-swappable switches add flexibility, but it may be less ideal for users requiring a full-size keyboard or very long wireless battery life with RGB enabled.

Key Features

• Compact 80-key layout includes alphanumeric, arrow, and function keys in a smaller footprint than full-size keyboards.
• Full-key hot-swappable PCB supports both 3-pin and 5-pin switches, allowing easy switch replacement without soldering.
• Multiple switch options including Kalih Box Strawberry Cream Pro linear switches, offering smooth and responsive typing.
• Small display screen shows battery status and active connection mode, providing quick at-a-glance info.
• Dual or triple connectivity modes: wired USB-C, Bluetooth 5.0, and 2.4 GHz wireless, enabling connection to up to three devices simultaneously.
• RGB backlighting with customizable effects enhances visibility and aesthetics but reduces battery life when active.
• Programmable top layer and Fn layer keys via driver software for personalized layouts.

Typing Experience

• Dye-sublimated PBT keycaps resist wear and offer a matte texture for comfortable typing.
• Ergonomic inclined design with narrow bezels supports a natural hand position.
• Switch options vary in actuation force and travel, catering to different tactile preferences.

Connectivity and Compatibility

• Wired USB-C connection ensures stable, low-latency use for gaming or work.
• Bluetooth 5.0 and 2.4 GHz wireless modes provide flexible multi-device use across Windows, Apple, Linux, and Android systems.
• Supports simultaneous connection to three devices, easing workflow across platforms.

Trade-offs

• Battery life ranges from up to 450 hours with backlight off to about 15 hours with RGB on, which may require frequent charging if lighting is used extensively.
• Compact TKL layout lacks a dedicated number pad, which may be less suitable for users needing extensive numeric input.
• Unknown details on case material and mounting style limit assessment of long-term durability and typing acoustics.
