Feature

●Buck boost function: the boost / buck module can be amplified or switched down to maintain a stable output voltage. It is small, powerful, highly efficient and stable in performance.
●Protection function: the power buck boost module supports 10A overcurrent protection, input undervoltage protection and high efficiency MOS input anti-reverse protection. Constant current values can be adjusted without multimeter. Scaled single turn potentiometers are easier to use.
●Buck application: the buck function is realized by the step-down circuit structure, and the output ripple voltage is quite low. For example, if the output is 12V 3A, it is 20mV, which is very suitable for powering speakers, audio amplifiers, artificial circuits, etc.
●Boost application: input 5 V to 30 V, can be used battery, lithium battery, AA rechargeable battery or can be used. Very low output ripple voltage. Low ESR capacitor + two-stage filtering, suitable for the power supply of audio amplifier boards and analogue circuits.
●LED light indicator: Red and blue light when constant current is charged, blue light only at constant voltage, blue and green light when almost fully charged, green light only when fully charged.
