Ready to make some sparks? This compact high-voltage module is perfect for tinkerers, students, or anyone who loves wild science demos. It takes a tiny 3V–6V DC input (think a couple of AA batteries or a small Li-ion pack) and boosts it up to a jaw-dropping 400,000 volts! Yeah, you read that right—it creates arcs up to 2cm long, perfect for experiments, ignition setups, or just impressing your friends. It's based on Tesla coil principles, so it's efficient, small, and super simple to use: just connect power, switch on, and watch the fireworks. Safety first, though—keep the arc distance short and avoid touching the output when live. We recommend using a beefy battery (2000mAh or more) for best results. Great for school projects, DIY ion generators, or adding some high-voltage fun to your workshop. Handle with care, keep sessions under a minute to avoid overheating, and always experiment responsibly. Comes as a ready-to-use module, so you can dive right in!
