What connectivity options does the LEOBOG K21 NumPad offer?

The LEOBOG K21 NumPad supports three versatile connectivity modes: Bluetooth 5.0 for wireless convenience, a super-fast and stable 2.4GHz wireless connection using the included receiver, and a Type-C wired mode for uninterrupted, low-latency use. This triple-mode design ensures you can use it seamlessly with various devices and scenarios.

Can I customize the switches on this numpad?

Yes! The K21 features a hot-swappable PCB compatible with both 3-pin and 5-pin mechanical switches such as Cherry, Gateron, Kailh, AKKO, and Otemu. This means you can easily swap out switches without soldering, allowing you to tailor the typing feel to your preference or try different switch types whenever you want.

What kind of typing experience does this numpad provide?

Designed with a PC mounting plate and equipped with EVA foam pads, the K21 offers a soft and responsive typing feel. The mounting plate enhances key stability and the foam helps absorb sound and reduce unwanted noise from the bottom case, resulting in a quieter and more comfortable typing session.

Are the keycaps on the K21 backlit?

Yes, the K21 comes with pudding-style keycaps that allow the backlighting to shine through beautifully. The backlight options include white light and RGB modes, providing both aesthetic appeal and functional illumination for use in low-light environments.

How long does the battery last on a single charge?

The built-in 600mAh battery delivers an impressive battery life of up to 50 hours on a full charge, depending on usage and backlight settings. This makes it reliable for extended use without frequent recharging.

Is the numpad compatible with different operating systems?

Absolutely. The K21 is compatible with both Windows and macOS systems, ensuring broad usability whether you're on a PC or Mac setup.

How portable is the LEOBOG K21 NumPad?

With compact dimensions of 12 x 8.2 x 3.7 cm and a lightweight design of just 0.2 kg, this numpad is highly portable and easy to carry around. It’s an excellent companion for those who need a numeric keypad on the go.

Does the numpad support NKRO (N-Key Rollover)?

Yes, it supports NKRO, which means every keypress is registered independently no matter how many keys you press simultaneously. This is particularly useful for fast typists and gamers who require accurate and simultaneous key inputs.

What is included in the package when I get the K21?

The package includes the LEOBOG K21 NumPad itself, a 2.4GHz wireless receiver for stable connection, a Type-C cable for wired use and charging, and a user manual to help you get started quickly.

Are the switches pre-lubed or do I need to lubricate them myself?

The LEOBOG Crystal switches installed on the K21 are pre-lubed, providing smooth and quiet keystrokes right out of the box, so you can enjoy a premium typing experience without extra modifications.

Product Description

The LEOBOG K21 NumPad is a compact 21-key numeric keypad designed for users who want flexible connectivity and easy switch customization. It fits well for office workers or hobbyists who need a dedicated numpad with wireless and wired options, plus the ability to swap mechanical switches without soldering. Its small size and multi-mode connection make it suitable for both desktop setups and portable use.

Key Features

Triple connectivity modes: Bluetooth 5.0, 2.4GHz wireless, and Type-C wired, allowing seamless switching between devices or connection types.
Hot-swappable PCB supports most 3-pin and 5-pin mechanical switches, enabling users to change switches easily for different typing feels.
Includes EVA foam inside the case to reduce typing noise and dampen bottom case sound, improving acoustic comfort.
White or RGB backlighting options enhance visibility in low-light environments.

Build Quality and Typing Experience

PC (polycarbonate) mounting plate offers a softer, more flexible typing feel compared to metal plates, which may suit users preferring less rigid feedback.
Plate-mounted stabilizers help reduce key wobble on larger keys for more consistent keypresses.
Pre-lubed linear switches with moderate actuation force provide a smooth, quiet keystroke suitable for office or home use.
Compact form factor (12 x 8.2 cm) keeps desk space minimal.

Connectivity

Bluetooth 5.0 allows wireless use with compatible devices, though latency and connection stability depend on environment.
2.4GHz wireless mode uses a dedicated receiver for potentially lower latency and more stable connection than Bluetooth.
Type-C wired mode ensures zero latency and no battery dependence during extended use.
600mAh battery supports up to 50 hours of use, though actual battery life varies with backlight and usage.

Compatibility

Supports Windows and macOS systems, covering most desktop and laptop users.
NKRO (N-key rollover) prevents missed keypresses during fast typing or multiple simultaneous inputs.

Trade-offs

Limited to a 21-key numeric layout, so it is not suitable for users needing full keyboard functionality.
PC mounting plate may not provide the firmer typing feedback preferred by some mechanical keyboard enthusiasts.
White or RGB backlight options are available, but lighting customization details are unknown.
Unknown firmware or key remapping support limits advanced customization possibilities.
