Compact size, high efficiency, stable and professional performance, dependable to use. 4. The input voltage is DC3.6-6V and will output about 500-1000KV high voltage. 5. Built to meet standard specification, strictly follow factory quality control. Specification: Condition: 100% Brand New Item Type: High-Voltage Generator Material: Plastic Color: As picture shown Input Voltage: DC3.6-6V Input Current: 2A-5A High Voltage Type: Pulse High and Low Pressure Integrated Output Voltage: About 500-1000KV (Please Pay Attention to Safety when Using) High Voltage Two Pole Discharge Distance: 10-15mm/0.4-0.6in. Package List: 1 x High-Voltage Generator Note: 1. The method to judge whether the battery capacity can drive the maximum output power is to measure the battery voltage when the arc is drawn. If it is around 6V, it can output the maximum power.2. The two sections of small capacity lipo batteries are connected in series at 7.2V. The measurement voltage has dropped to about 4V in the arcing state. The smaller the capacity, the lower the voltage. Therefore, it is recommended to use lipo batteries above 2000MA, and it is best to match batteries above 4000MA if possible.
