Features Specification: Item Type: High-Voltage Generator 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.
