Welcome to our shop! The high-voltage module/generator made by the circuit composed of components can be used as a high-voltage source for school scientific experiments, electronic devices, negative-ion generator, and science small productions. Adopting the Tesla coil principle, it outputs high-voltage pulses with powerful discharge intensity. This compact-sized generator offers high efficiency, stable and professional performance, making it dependable to use. The input voltage ranges from 6V to 12V, and it will output about 500KV high voltage. It is built to meet standard specifications and strictly follows factory quality control. The high-voltage generator is made of plastic and has a length of approximately 69.5mm and a diameter of approximately 33.5mm. The input line length is about 25cm, and the output line length is about 92cm. The high voltage discharge distance is between 1cm and 4cm. To power the generator, you can use a single section 3.7V lipo battery or two series connections such as an 18650 battery, idle mobile phone battery (remove protection board, recommended capacity is above 2000mAh), or nickel-cadmium/nickel-hydrogen battery pack. You can also use a 6V or 12V lead-acid battery for the best effect. 100% Satisfaction: Our customers are our top priority.
