About This

  • 1.Uninterrupted Power Supply: Designed specifically for routers, cameras, and development boards, our high power UPS battery backup ensures your devices keep running without interruption during power outages. With a seamless switch to battery power, you never have to worry about disconnections again.
  • 2.Efficient Charging and Power Management: Our module, featuring a step-up charger board, is equipped with dual 18650 battery sockets and a universal Micro USB charging port. It supports direct DC5V input for effective lithium battery charging, enhanced by a dual-color LED indicator for charging status.
  • 3.Advanced Boost Circuit for Superior Performance: The cutting-edge boost circuit delivers peak power of up to 20W and a rated power of 15W. With a built-in 12A high current MOS and an efficiency of up to 96%, the module ensures high performance.
  • 4.Reliable UPS Functionality for Continuous Power: Our UPS function ensures that your devices are continuously powered during an outage. It seamlessly switches from power supply to battery without interrupting device operation, ensuring your network stays up when you need it the most.
  • 5. Smart Design for Enhanced Usability: To address the issue of slow switching to battery power in some power supplies, our module includes an output capacitor with a larger capacitance value. For those encountering delayed switching, attaching a 1K discharge resistor at the 5V input port can significantly improve response time, enhancing the overall experience.
