1) Nonlinear super power constant current switch of intelligent charger
2) In a certain voltage, the battery of charger can maintain a constant current, and can control itself hen the battery is full
3) The charge has three modes (H is big charged current, L is a small charging current, O for USB charged external mobile equipment)
- When the switch position is H mode charging the battery under 2.5V, the charging current is 850mAh - 900mAh
- When the switch position is L mode charging the battery under 2.5V, the charging current is 425mAh - 450mAh
4) The charge inside using PWM control mode charging, it is high voltage and big current constant current charging, it can achieve the purpose of rapid charging
5) The charge is anti battery inversion circuit, it can protect the battery and charger from damaging because of battery inversion
6) The charger can only charger the 3.7V lithium battery
