Features: _x000D_High temperature arc igniter, with 3-6v high power, instant ignite cigarette & paper, can work for 20 seconds continuously, and high frequency, good quality, easy to use. _x000D_It can be used as high voltage source for high school science experiment, electronic instrument, negative ion generator and little science. _x000D_It can generate high temperature and high frequency arc, can easily ignite combustible. _x000D_According to the tesla coil principle, the module outputs high voltage pulse current, small volume and high efficiency. _x000D_The peripheral circuit is simple (simply connect the switch, Install the battery), the discharge intensity is violent. _x000D_Specifications:_x000D_Size: 55*24*22mm/2.17*0.94*0.87inch_x000D_Input voltage: 3V-6V_x000D_Input Current: 0.5A-2A(depending on the input voltage)_x000D_Input line length: about 10cm/3.94inch_x000D_High Voltage type: DC type_x000D_Output voltage: about 700KV (please pay attention to safety when used) _x000D_Output current: 0.5A _x000D_Output line length: about 10cm/3.94inch_x000D_High voltage poles ignition distance: 1.5cm(1.5cm is maximum distance, 1cm is better) _x000D__x000D__x000D__x000D_Note: _x000D_1.Input the power of 3-6v, output two levels of terminal can produce 1.5cm length purple high temperature arc, instant ignition paper, single high voltage line can also discharge of any metal body, working without a crack sound. _x000D_2.On the input power: 3.7-v lithium battery can be used in series, such as 18650 battery, idle cell phone battery (to remove the protection board, recommended capacity above 2000mAh) or Nickel-cadmium/Nimh battery pack, 4V or 12V lead Acid batteries(12V battery works best) _x000D__x000D__x000D_Module Usage Precautions: _x000D_1. Avoid power on when No load. You must adjust the appropriate distance for high-voltage terminal before power on, high-voltage line arc distance is proportional to the battery voltage and capacity. _x000D__x000D_2. The test arc distance from the short to long experimental, It is prohibited exceed the maximum arcing distance(
