Constant current: The integrated operational amplifier technology is used to precisely control the charging current. Regardless of the degree of battery power loss, the charging current is constant at the set value to protect the battery and prevent the battery life from being shortened due to overcurrent charging.

Voltage limit: using precise sampling, stable reference and pulse width modulation (PWW) technology to ensure that the output voltage will not be higher than the set value and lower than the full value.

Automatic floating charge: The product can automatically detect the voltage at both ends of the rechargeable battery and the degree of power loss of the rechargeable battery, thereby controlling the output charging voltage and charging current. When the charging current is close to the full value, the internal charging power will be automatically changed to make the output change Floating state to protect the battery and ensure the charging power.
