The KUWAJIA adapter solves this issue by introducing an innovative, electromagnetic auto-eject mechanism. The moment your device completes its charge, a built-in spring-loaded system releases and physically disconnects the power flow. This ensures a true physical power cutoff, providing absolute safety and preserving long-term battery health.

• Electromagnetic Auto-Eject Technology: Features a dynamic mechanical mechanism that releases the magnetic hold and utilizes a built-in spring to physically disconnect power at a full 100% charge. 
• 140W Ultra-Fast Power Delivery: Fully supports advanced high-speed fast charging protocols up to 140W, letting you charge demanding devices like laptops, tablets, and smartphones at maximum velocity. 
• Dual Current Identification Modes: Integrated dual-color light indicator modes optimize cutting times based on the target device:
  • White Light Mode: Tailored for smart devices with active screens (e.g., phones, tablets, laptops). It completes a 10-to-50-minute trickle charge after showing 100% to guarantee the battery is genuinely full before ejecting.
  • Blue Light Mode: Programmed for smaller, screen less accessories (e.g., power banks, Bluetooth headsets, shavers, toys). It safely triggers a hard power cutoff roughly 5 minutes after a full charge is reached. 
• Advanced Thermal Control: Actively prevents overnight overheating, keeping charging temperatures lower and safer while you sleep.
• Universal USB-C Compatibility: Acts as a versatile, protective bridge for standard Type-C setups, making it fully compatible with Android devices, newer iPhones, MacBooks, iPad models, and portable gaming consoles.
