  • The buck power converter input voltage range is DC 5V-30V, output voltage range is DC 0.8-29V, output current is 5A(Max).
  • Module using imported high quality chip, high efficiency (up to 95%), and heat is small, can go to 5A current, at the same time with the original TI operational amplifier to control the output current, the overall output is very stable.
  • It adopts dual high-quality LED display of voltage and current which is visible and easy to read even under sunshine.
  • Blue LED indicator lights on when the meter is charging while red LED lights on when the meter is full-charge
  • There are two LED indicators on the step-down voltage regulator board, including the red LED and the Green LED the red LED will light on when you measure input Voltage and Green LED will light on when you measure output Voltage

When the lithium-ion battery voltage is relatively low, if the direct use of constant voltage charging, the voltage difference due to the larger, leading the charge current is too large, resulting in damage to the battery, so when you want to start using the constant battery current charging, when the charge to a certain extent automatically switches back when the constant voltage charging.
