Product information

Description

Redragon K4PUC21N0 PRO is a 75% mechanical keyboard combining a compact layout with features commonly found on full-size models. It offers triple connectivity — Bluetooth, 2.4 GHz wireless and wired USB — so you can use it across different devices and platforms. The Logan Kapuczino edition adds a distinctive color scheme and themed graphics. The keyboard includes Lion L switches with hot-swap capability, gasket-mount construction and full RGB backlighting, providing a balance of tactile response, customization and durable construction suited to extended use.

Advantages

The 75% layout saves desk space while retaining essential function keys and a dedicated knob for quick control of volume and lighting. Lion L mechanical switches deliver consistent tactile feedback suitable for typing and gaming, while the gasket-mount design softens key impact for a more comfortable typing feel. Hot-swap sockets allow changing switches without soldering, and RGB lighting with 16.8 million colors enables visual customization. Multiple connectivity modes ensure compatibility with desktop and mobile setups.

Suitable for

  • Desktop workstations with limited desk space
  • Gaming sessions requiring compact keyboards and fast response
  • Users who want to customize switches and lighting

How to use

Connect via the provided USB cable for wired operation or switch to Bluetooth or 2.4 GHz wireless mode following the keyboard’s pairing instructions. Use the knob to adjust volume and cycle lighting effects; access multimedia functions through the dedicated keys. If you want to change switches, power off the keyboard, remove the keycaps and pull out the switches from the hot-swap sockets, then insert compatible replacement switches. Adjust lighting and key assignments through on-board shortcuts or compatible configuration software when available.

Usage recommendations

For stable performance during extended sessions, use wired mode when possible; keep firmware and configuration software up to date and handle hot-swap operations with the keyboard powered off. Clean keycaps and surrounding areas regularly to maintain switch responsiveness and lighting clarity.
