The type of pulse current Output voltage: 20kv (Please pay attention to safety),Input Output power cord length: 100 mm/3.94inch. Input the power of 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. The high voltage pulsa arc generator can generate high temperature and high frequency arc, can easily ignite combustible; With 3-6v high power, the pulsa arc generator instant ignite cigarette & paper, can work for 20 seconds continuously, and high frequency, good quality, easy to use. Applications: Used as high voltage generator, high voltage Igniter; Ideal for students to study electrical experiment, do science experiment, etc.
