3Pcs DC 3.6V-6V to 20kv 20000v 1.5A Boost Step Up Power Module High Voltage Generator DC Transformer Converter Module

_ The high-voltage module is made by using the tesla coil principle, and outputs high-voltage pulse high-voltage current, small volume, high efficiency, simple peripheral circuit (just need to connect the switch, the battery can be) the discharge intensity is fierce.
_ About 20kv boost step up power module the power supply: you can use a single 3.7V lithium battery or two series, such as 18650 battery, idle mobile phone battery (to remove the protection board, recommended capacity above 2000mAh).
_ The input voltage of the arc generator is dc 3.6 -6V and output dc 20000v high voltage, input
wiring: red - positive
_ green - negative
_ output wiring: the other side same color cable.
_ 20kv boost step up module can be used as high-school scientific experiments, electronic devices, negative-ion generator, high-voltage source, to use when small science.
_ The high-voltage module should avoid the use of high-voltage current without a load. Power must be set to a suitable distance to the hig
