  • Charging function: pressing the transparent button can change the charging modes (0.5A/1A/2A)
  • Low power warning: place a battery into one of the slots and the button will flash BLUE if the battery is lower than 15% and means that the battery definitely needs recharged.
  • Zero Voltage Activation Function: when charger is in standby, place over-discharged battery (output under 2V), zero voltage activation starts for safer more thorough charging cycle.
  • Overcharging function prevents charging when the battery is full
