This module is a finished module of transformer/booster for school scientific research projects, self-defense stun guns, and mosquito swatter.
It can output high voltage pulse current, small size, and high efficiency.
The input voltage is DC 3.7V to 6V and will output tens of thousands of DC high voltage.
It can be used for a negative-ion generator, electronic instrument, and science experiment.
The peripheral circuit is simple, simply connect to switch and battery, and the discharge intensity is great.
