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 high voltage output line, the battery capacity is proportional to the distance and the use of the high pressure arc (not a voltage as high as possible, must provide sufficient current).
