3. Operating Instructions

The imokin 40W Dual Port USB C Charger Block is designed for efficient and safe charging. Understand its capabilities for optimal use:

  • High-Speed Charging: Each USB-C port can deliver up to 20W independently. When a single device is connected to either port, the charger can deliver a maximum output of 40W, enabling rapid charging for compatible devices like iPhones (up to 60% in 30 minutes).
  • Dual Device Charging: When two devices are connected simultaneously, the 40W power is intelligently distributed between the two ports, typically providing 20W to each port. This allows for efficient charging of two devices at once.
  • GaN+ Technology: The charger incorporates GaN+ (Gallium Nitride) technology, which allows for a smaller, lighter design while maintaining high power output and efficiency. This technology also contributes to reduced heat generation during operation.
  • Safety Features: Built-in safety mechanisms protect your devices against over-current, over-voltage, short-circuiting, and overheating. The charger continuously monitors temperature and output to ensure safe charging.
