🆚 Model Difference (read before choosing)
56 mm / 400 Kv
Use when: You want the compact 400 Kv version designed for 3.7V–6V input sources.
Why pick it: Good for smaller low-voltage setups where compact size matters.
63 mm / 400 Kv
Use when: You want the other 400 Kv version, but your input range is 3V–6V.
Why pick it: Better when your source starts lower and you want the 63 mm body style shown in this listing.
69 mm / 500 Kv
Use when: You need the 500 Kv model and plan to use a higher input range of 6V–15V.
Why pick it: Good for users who want the mid-range variant in this listing with broader DC input flexibility.
88 mm / 1000 Kv
Use when: You need the 1000 Kv model and your power source is 3.7V–7.4V.
Why pick it: Best for users who want the higher nominal class while staying in a low-voltage battery range.
100 mm / 2000 Kv
Use when: You want the highest nominal class in this listing and plan to use 12V input.
Why pick it: Best for users who need the largest body version shown here.
Important: The 400Kv / 500Kv / 1000Kv / 2000Kv labels are best understood as model identifiers / nominal marketplace classes, not as a guarantee that every setup will produce identical real-world voltage, arc length, or performance.

Variant Guide
56 mm / 400 Kv: input 3.7V–6V
63 mm / 400 Kv: input 3V–6V
69 mm / 500 Kv: input 6V–15V
88 mm / 1000 Kv: input 3.7V–7.4V
100 mm / 2000 Kv: input 12V
🔋 Power Source Guide
Suitable power sources may include single lithium cells, 2-cell lithium packs, NiCd / NiMH batteries, or lead-acid batteries, depending on the input requirement of the selected variant.
Higher-capacity batteries usually provide better short-term discharge performance than weak or low-capacity cells. If the battery sags heavily under load, arc performance will usually drop as well.
🧠 Quick Selection Guide
Need the most compact 400 Kv version? Choose 56 mm / 400 Kv.
Need a 400 Kv version starting from 3V input? Choose 63 mm / 400 Kv.
Need broader DC input up to 15V? Choose 69 mm / 500 Kv.
Need the 1000 Kv nominal model? Choose 88 mm / 1000 Kv.
Need the largest 12V variant in this listing? Choose 100 mm / 2000 Kv.
🧰 Typical Applications
High-voltage electronics experiments
Educational demonstrations
Controlled ignition / arc-effect testing in bench setups
Capacitor charging for compatible electronic projects
DIY high-voltage research and bench work
🔌 Wiring & Safety
Verify the exact input voltage for the selected variant before connecting power.
Set a safe and controlled output gap before powering on.
Connect the low-voltage input side with correct polarity and keep all high-voltage output wiring well isolated.
Use only in dry, controlled work areas, away from conductive debris, flammable materials, vapors, and accidental contact points.
Do not operate continuously for long periods, as the module may overheat and fail.
For best results, test arc distance gradually from short to longer spacing.
⚠️ Important Notes
This product can generate dangerous high voltage and hot arcs.
It is intended for experienced users only.
It is not a finished consumer appliance, not a regulated power supply, and not intended for continuous-duty operation.
Never power the module with an excessive uncontrolled output gap or unstable no-load condition.
Weak batteries may cause poor output and heavy voltage sag.
Incorrect polarity or improper handling may permanently damage the module.
