This product is an adjustable buck - boost source. It has the capability to keep the constant output voltage, regardless of whether the input voltage drops below the output value or increases over. The source has 3 adjustable potentiometers, ie output voltage regulation, maximum output current regulation and minimum input voltage regulation.

The role of each of the three potentiometers can be seen in the presentation images. The ability to adjust the minimum input voltage helps to protect your overcharge batteries and keep them in good condition. In most cases, even if the source is able to maintain the output voltage even if the voltage drops greatly, it is advisable not to fall below a value of 3.1 - 3.3 V per cell of a LiPo battery.
