High Voltage Transformer – 3.7V-4.2V To 15kV Boost Step-Up Power Module – HV Pulse Generator For Science Experiments, Ionizers & Ignition Projects

About This Product

This little black module is a high voltage step-up transformer that takes a 3.
7V to 4.
2V input – think standard lithium battery voltage – and boosts it all the way up to a whopping 15 kilovolts.
Yeah, that's a lot of juice for something this tiny (about 1 inch long).

Input current is up to 2 amps, and it draws about 0.
4 amps on the high voltage side.
Spark distance is around 0.
5 to 1 centimeter – enough to make some impressive arcs.
Just be careful because this thing gets hot – we're talking hot enough to ignite paper, plastic, or even fine wire if you're not paying attention.

Inside, it's got a clever winding setup: the high voltage winding is on the inner layer, separated in segments and encapsulated in resin, while the low voltage winding is on the outside.
The primary has two windings – one main and one feedback winding.

Great for middle school or hobbyist science experiments, negative ion generators, small ignition projects, or just showing off some cool sparks.
If you're into DIY electronics or need a compact HV source, this thing delivers.

Just be safe with it – 15kV is not a toy.
