Unleash Extreme Voltage from Minimal Power This high-voltage step-up power module represents a breakthrough in compact voltage conversion technology. Using advanced boost converter principles, it transforms a modest 3.7-6V input from standard lithium batteries into an impressive 400kV output capable of producing dramatic electric arcs. Whether you're building a Tesla coil, conducting physics experiments, or creating an arc igniter, this module provides the raw high-voltage power you need in a remarkably compact form factor. How This Solves Your High Voltage Challenges Traditional high-voltage generation requires bulky transformers, complex circuits, and mains power connections. This module eliminates those barriers by delivering industrial-strength voltage from battery-powered sources you already own. The cylindrical design (56mm length × 24mm diameter) fits easily into portable projects, while the pre-wired input and output connections mean you can start experimenting immediately without complex soldering or circuit assembly. Professional-Grade Performance in a Portable Package The module utilizes high-temperature silicone wiring designed specifically for high-voltage applications, ensuring safe energy transfer even during intense discharge events. With dual high-voltage output wires and clearly marked polarity on input leads (red positive, black/green negative), integration into your projects is straightforward and foolproof. The bipolar discharge capability produces visible arcs ranging from 1-2cm depending on your power source, creating stunning visual effects for demonstrations or functional ignition systems. Optimal Battery Compatibility This module performs best with 6V power sources, though it operates across the full 3.7-6V range. For maximum performance and sustained operation, use lithium batteries with capacity exceeding 2000mAh—ideally 4000mAh or higher. Single 3.7V cells work for basic experiments, while dual 18650 batteries in series (7.4V configuration) provide extended runtime, though voltage monitoring ensures you maintain optimal 6V operation during arc discharge.
