MCU controlled, adopts using -∆V intellectual cut-off charging method, automatically turn to trickle charge, prevent the batteries from over-voltage, over-current or over-heat.
AC and DC input design (AC cable provided only), applied to worldwide voltage – AC 100-240V 50/60Hz, convenient everywhere.

Automatically stop charging when detecting improper input voltage, defective or short circuit or non rechargeable batteries. Constant current charging mode would protect the batteries against current fluctuation and keep using the charger safely.
