This high-voltage module uses the idea of a Tesla coil to make high-voltage pulse output voltage current, small size, high efficiency, simple external circuit (just plug in the battery) discharge intensity violent.
Power connection:
Red "+"
Green "-"
Output:
Both same color cable
Specifications:
High pressure discharge distance between: 10 mm - 20 mm
Package Content
1 x High Voltage Generator
Power Input
Using one or two 3.7V battery, such as 18650, idle cell phone batteries ( to remove the protection board , the proposed capacity of 2000mAh or more ) or NiCd / NiMH battery pack, 4V or 6V lead acid batteries.

This module is a small production with high-pressure science inverter transformer / booster finished module, the input terminal DC 3V - 7.2V can get DC high voltage (about 1-2 cm arc) at the output can be used as high school science experiments , electronic equipment, negative ion generator, high voltage source to use when making small science.
