Frequently Asked Questions

Q: What power supply does the Mini Tesla Coil Kit require?

A: The mini coil module operates on a DC input voltage of 9–12V. A standard 9V battery is sufficient to start the module, but if you want to generate a visible high-voltage arc, a 12V power supply with at least 1A (ideally 2A) is required for stable operation.

Q: Is this mini coil kit safe to use indoors?

A: Yes, under normal conditions the module is safe for indoor use. However, it produces a strong electromagnetic field that can interfere with or damage sensitive electronics within half a metre. Always keep smartphones, cameras, and similar devices at least 1 metre away from the coil while it is energised.

Q: Is this kit suitable for school science projects and STEM learning?

A: Absolutely. This mini Tesla coil module is an excellent hands-on educational tool for demonstrating electromagnetic induction and wireless electricity transmission. It is widely used in science fairs, STEM classrooms, and hobbyist electronics workshops. Adult supervision is recommended for younger students.

Q: Do I need soldering skills to assemble this kit?

A: The product is described as a finished module, meaning it arrives pre-assembled and ready to connect to a power source. However, a soldering iron, glue, and sprue cutter may be needed for optional customisation or mounting with the included screws and standoffs.
