Product Overview This product is a high-voltage pulse arc generator specially designed for a single 18650 lithium battery. The input voltage is strictly limited to 3V-4.5V, and the output voltage can reach 15KV, generating low-temperature white arcs. It is suitable for scenarios such as scientific research experiments and special effects demonstrations. Overpressure use is strictly prohibited; otherwise, it may lead to serious consequences such as module explosion and combustion! Core parameters Input voltage: 3V-4.5V (4.2V is recommended) Input current: 1.5A-3A (varies with load) Output voltage: 5KV-20KV (Voltage increases with input) Pulse capacitance: 20KV/102/1000pF Pulse frequency: 3-20 times per second Arc distance: 1cm-1.5cm Arc characteristics: White, low temperature Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
