🧠 Product Description
This kit is intended for experimental high-voltage generation from a 3.7V–4.2V DC source. When properly assembled and powered within its intended input range, seller listings describe it as producing an approximate 15KV high-voltage output capable of generating a short visible arc.
It is commonly marketed for science demonstrations, educational electronics projects, negative-ion / ionization experiments, and other small DIY high-voltage builds. Real arc length and performance depend on the power source, assembly quality, wiring, and load conditions.
To avoid ambiguity: this product is best described as an unassembled low-voltage-to-high-voltage experimental arc generator kit. It is not a finished consumer appliance, not plug-and-play, and not intended for beginners or unsupervised use.
