Want to make your own arc generator? In this video, I walk you through the entire build step by step.

• 3x 18650 batteries in series (12V total)

• 20A 3S Li-ion protection board (overcharge / over-discharge protection)

• 12.6V fast charging module with QC support

• Boost converter module: 12V → 20,000V @ 70W

• Battery level display (optional, but recommended)

• AB glue + 704 silicone rubber for insulation and assembly

The arc is high voltage but very low current (~0.1–0.5mA) — it looks intense but won't hurt you. No worries about getting electrocuted (unlike mains power).

Perfect for DIY projects, high-voltage experiments, or just making cool sparks.

📌 Full wiring details and part list are shown in the video.
⚠️ Always insulate the high-voltage pins with 704 glue.
