Features 【High voltage output】This module can output a high voltage pulse current of up to 1000kV. 【Small size and high efficiency】The module is compact and efficient, making it suitable for small scientific productions. 【Versatile applications】It can be used in a wide range of applications, including negative-ion generators, electronic instruments, and science experiments. 【Simple circuit】The peripheral circuit is simple, and only requires the switch and battery to be connected. 【Powerful discharge】The discharge intensity is great, making it a reliable and effective tool for high voltage pulse generation. Specifications:Input Voltage: 6V~12V DC Input Current: 2A~5A (related to voltage)Output Voltage: About 500KV~1000KV Input Cable Length: About 100mm(red is positive)Output Cable Length: About 100mmArc Discharge Distance: 10mm~20mmInstruction:1. You can use two 3.7V lithium batteries in series, such as 18650 batteries, idle mobile phone batteries (remove the protection board, the recommended capacity is more than 2000mAh) or nickel-cadmium/nickel-metal hydride battery packs, 4V or 6V batteries. 2. This module is a finished module of high-voltage inverter transformer/booster for scientific small production. After inputting DC6-12V voltage at the input end, a DC high voltage of about 500,000 volts (about 1-2 cm arc) can be obtained at the output end. ), can be used as a high-voltage source for general experiments, electronic instruments, negative ion generators, and small scientific productions in Chinese subjects. Note: 1, Output ends of cable should be adjusted properly before power on, and the arc distance depends on battery voltage and capacity. 2,  The arc distance should be from short to long, do not produce a longest arc at first or the module might be damaged easily. 3, The module has high power and inner heat is not easily dissipated, so it can not work continuously for long time (<10 seconds each time).Package Includes:1 x High Voltage Generator Package List 1 x High Voltage Generator
