UGREEN KU004 Wireless Chocolate Membrane Keyboard
The UGREEN KU004 Wireless Chocolate Membrane Keyboard (UG-35735) combines sleek aesthetics with practical functionality. This slim profile keyboard delivers a comfortable typing experience while providing wireless freedom and compatibility across multiple operating systems.
Low-Profile Chocolate Key Design
The KU004 features a distinctive key structure inspired by chocolate bar aesthetics:
- Ultra-thin 7.2mm key cap height reduces finger travel distance
- 3mm key travel with scissor mechanism provides tactile feedback
- 60±10g actuation force balances responsiveness with typing comfort
- 1.5mm actuation point for faster keystroke registration
- Island-style key layout with 19mm key pitch matches standard typing patterns
This low-profile design reduces wrist strain during extended typing sessions. Additionally, the scissor mechanism under each key ensures stable keystrokes with minimal wobble compared to standard membrane keyboards.
Multi-Device Wireless Connectivity
The KU004 offers versatile connection options to enhance productivity:
- Triple-mode connectivity via Bluetooth 5.0, Bluetooth 3.0, and 2.4GHz wireless
- Seamless switching between three paired devices with dedicated selector keys
- 10-meter effective wireless range in open environments
- Nano USB receiver storage slot within keyboard body

These connectivity features make the UGREEN KU004 exceptionally adaptable to various work scenarios. Furthermore, the ability to switch instantly between devices enhances workflow efficiency for users managing multiple systems.
Extended Battery Performance
The KU004 incorporates power-saving technologies for reliable operation:
- Dual AAA battery power source provides up to 24 months of typical use
- Intelligent power management automatically adjusts to typing patterns
- Sleep mode activates after 10 minutes of inactivity
- Battery level indicator provides advance warning of power depletion
- Physical power switch for complete shutdown during travel or storage
These power efficiency features minimize maintenance requirements and operating costs. Consequently, users experience fewer interruptions while maintaining productivity across extended work periods.
Enhanced Typing Experience
The KU004 includes thoughtful features to improve comfort and functionality:
- Adjustable tilt feet with two elevation options (6° and 9°)
- 12 multimedia function keys for quick access to common commands
- Spill-resistant design protects internal components from minor liquid exposure
- Whisper-quiet keystroke sound profile (below 58dB) for shared environments
- Laser-etched key legends for long-term visibility and wear resistance
These enhancements transform typing from a basic input method to a refined experience. Moreover, the quiet operation makes the UGREEN KU004 suitable for noise-sensitive environments such as libraries or shared workspaces.
Space-Efficient Full Layout
The KU004 maintains a complete key arrangement despite its compact footprint:
- Full 104-key layout including dedicated numeric keypad
- Standard QWERTY configuration familiar to most users
- Dedicated media control buttons for volume and playback
- Function key combinations for additional commands
- Optimized 17.1″ × 5.0″ dimensions reduce desk space requirements
This space-conscious design provides complete functionality without unnecessary bulk. As a result, the UGREEN KU004 fits comfortably in smaller workspaces while maintaining full keyboard capabilities.
Ideal For These Users
The KU004 is particularly well-suited for:
- Office professionals seeking a low-noise typing solution
