It can output high voltage arc: small size and high efficiency. The input voltage is DC3.6-6V and will output DC20KV high voltage. It can be used for high voltage experiment, teaching, and product development. Two high voltage wires can light up cigarette or paper, single high voltage wire can discharge to any metal quietly. Specifications: Input Voltage: DC3.6V-6V Working Current: 1.5A Output Voltage: DC20KV Output Current: 0.05A Electric Arc Distance: 5mmRed Wire: Input positiveGreen Wire: Input negative 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. Package Includes: 1 x High Voltage Generator
