400 kV High Voltage Generator for Scientific Experiments and Tesla Discharges
You already have the maximum available quantity in your cart.
This high voltage generator produces pulsed discharges with a voltage of up to 400,000 V and is ideal for school experiments, scientific projects, the construction of negative ion generators, or plasma effects. It operates on the principle of a Tesla transformer and offers compact dimensions and high efficiency.
Power is supplied via batteries (e.g. 18650), and it is only necessary to connect the switch. The device generates a high voltage arc that can jump a distance of up to 2 cm. Due to its small size and simple connection, it is ideal for hobby use and educational purposes.
- Input Voltage: DC 3–7.2 V
- Input Current: 2–5 A
- Output Voltage: up to 400,000 V (pulsed current)
- Discharge Distance: 10–20 mm
- Length of Input Cables: approx. 10 cm (red +, green -)
- Length of Output High Voltage Cables: approx. 10 cm
- Module Dimensions: 65 × 24 mm (maximum diameter 24 mm, minimum 22 mm)
Package Contents:
1x 400 kV high voltage generator with cables
Important Notices:
- High voltage is dangerous – always exercise increased caution when using.
- Do not operate idle (without discharge) – this may damage the module.
- The module is not designed for continuous operation – the internal structure is not cooled.
- It is recommended to use a high-quality battery with a capacity of at least 2000 mAh, ideally 4000 mAh or more.
This high voltage generator is intended for educational, demonstrational, and scientific purposes. It is not suitable as a lighter or for directly igniting objects – discharges are very hot, but continuous operation may damage the device.
