Description Note: The color of the item may vary slightly due to photography and your own computerFeature:This module is a small production with high-pressure science inverter transformer / booster finished module, the input terminal DC4.8V-7.2V voltage can get 500,000 volts DC high voltage(about 1-2 cm arc) at the output.The module can be used as high school science experiments, electronic equipment, negative ion generator, high voltage source to use when making small science.About Power :3.7V battery can be used with two series, such as 18650, idle cell phone batteries (to remove the protection board, the proposed capacity of 2000mAh or more) or NiCd / NiMH battery pack, 4V or 6V Lead Acid batteries.Note:1. The high-voltage module should avoid the use of electricity in high voltage no-load. Power must be adjusted to a suitable distance to the high-voltage output line, battery capacity is proportional to the distance and the use of the high-pressure arc (not a voltage as high as possible, you must provide enough current). 2. Experimental test of the arc distance from short to long. Do not exceed the maximum arc distance electricity, energy can not be released due to high pressure, can easily damage the module.3. Due to power, the internal heat is not easy, every power-on time should be controlled within 10 seconds.4. Determine whether the battery capacity can be driven approach is the maximum power output of the battery when the voltage measurement arcing. If so you can 6V maximum power output.5. Two sections of small capacity series of 7.2V, measured arc voltage has dropped to about 4V state, the capacity of the smaller voltage pulled lower. It is recommended to use more than one battery 2000mA,and it is best to use one battery more than 4000mA.Specification:Material: Metal, PlasticColor: BlackSize: 88 x 26 x 23 mm(L x W x H)Weight: 66gInput Voltage: DC3.6V-6VInput Current: 2A-5AOutput Voltage: DC 500KV-1000KV (Please pay attention to safety when used)Input Line Length: about 100mm (red is positive)Output Line Length: about 160mm High voltage bipolar discharge distance: 10mm-20mmHigh type: Pulse CurrentStructure: high and low voltage integratedPackage Include:1 x 1000KV Boost Step-up Power Module
