Features: 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. It can be used as high voltage source for high school science experiment, electronic instrument, negative ion generator and little science. It can generate high temperature and high frequency arc, can easily ignite combustible. According to the tesla coil principle, the module outputs high voltage pulse current, small volume and high efficiency. The peripheral circuit is simple (simply connect the switch, Install the battery), the discharge intensity is violent. Specifications: Size: 55*24*22mm/2.17*0.94*0.87inch Input voltage: 3V-6V Input Current: 0.5A-2A(depending on the input voltage) Input line length: about 10cm/3.94inch High Voltage type: DC type Output voltage: about 700KV (please pay attention to safety when used) Output current: 0.5A Output line length: about 10cm/3.94inch High voltage poles ignition distance: ≤1.5cm(1.5cm is maximum distance, 1cm is better) Note: 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. 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) Module Usage Precautions: 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. 2. The test arc distance from the short to long experimental, It is prohibited exceed the maximum arcing distance(
