Industrialgrade main control chip for reliable performance and long service life Largescreen LCD display for clear, realtime monitoring Shows charging current and discharging current Displays accumulated power generation and discharge Temperature readout and status indicators Light control with delay function Adjustable charging and discharging parameters Poweroff memory to resume previous state Dual USB outputs for convenient charging Dual USB ports with a maximum current up to 2.5 A Suitable for powering and charging connected devices Complete 3stage charging management Provides safe and efficient charging with threestage control Use scenarios Home or office energy storage and device charging: monitor battery status, reuse stored energy, and keep devices powered via USB while keeping an eye on temperature and charging parameters. Workshop or field battery management: set and adjust charging and discharging parameters to suit different battery packs, monitor currents and temperature, and use the light and delay controls to illuminate work areas as needed. Offgrid or temporary setups: rely on the threestage charging management and the poweroff memory to maintain consistent performance and quickly resume operation after interruptions, while charging essential devices through the USB ports.
