## Overview

The DAOKI 2Pcs 15KV Ignition Generator Kit is a high-frequency boost step-up transformer suite designed for electronic enthusiasts and DIYers. It delivers a powerful 15KV output from a compact 3.7V input source, typically a 18650 battery, enabling instant ignition of combustible materials through a stable plasma arc. The kit includes all necessary components for easy assembly and reliable performance, making it ideal for scientific experiments, plasma lighters, and electronic projects requiring high voltage ignition.

## Description

Description:  Features: This product is a booster coil production suite, the circuit is simple and reliable, with a professional line drawings, electronic research convenience enthusiasts  Specification: 15KV transformer outside dimensions of approximately: 27×16×21mm/1.1 x 0.6 x 0.8inch Input voltage: DC 3.7V-4.2V (limit 12v, easy to damage not recommended, this transformer is equally applicable to 12V input voltage, but requires a corresponding increase in the base of the feedback resistor to about 150Ω ~ 1.5KΩ, its resistance should be large to replace a small adjustment, or burned transistor or transformer) Input Current: less than 2A Output voltage: approximately 15KV (please pay attention to safety when used) Output Current: ≤0.4A High voltage bipolar ignition distance: ≤0.5 cm  When the product input termination 3.7V-4.2V power supply, the secondary high voltage output is not connected to high-voltage rectifier diodes and capacitors, output terminals levels ≤1.5cm long can produce purple high temperature arc, no crackling, but the temperature is very high , you can easily and instantly point cigarette paper, or even very thin wire burned Sparks.  Transformer structure: There are two primary windings, a primary winding, a feedback winding, the secondary output of high pressure. Other: 15KV transformer designed for maximum output, limit output cannot exceed 15KV, is one centimeter arc, a higher output voltage is likely to damage the transformer. PCB board size: 4.2 x 3.2 x 0.16cm/1.7 x 1.3 x 0.06inch;  Package Include: 2 x 15VKE = 1 type step-up transformer 2 x PCB Board 2 x 120 ohm resistance 2 x UF4007 ultra-fast recovery diode 2 x N20 transistor 2 x Heat sink 2 x M3 * 6 screws 2 x Boat switch 2 x 3-Pin 2 X 18650 Battery Holders

## Features

## Customer Reviews

### ⭐ Low quality
*by S***C on December 17, 2020*

This could have been a really cool kit but that tiny flyback transformer has issues.In the first set, the negative wire was detached and there's no practical way to reattach it. It seems like they crush the edges of the coil housing to secure it rather than a dab of glue or whatever.The second one looked okay but I foolishly tried to solder the wires to the circuit board. Don't do this. First, sand the ends of the wires with actual sandpaper to get off the lacquer insulation. Break off three of the pins from the pin header that was included and solder that into the holes. Then wrap your coil wires around those pins and solder to the pin if you can.I still couldn't get this to work but maybe I can reuse the ferrites...

### ⭐⭐⭐⭐⭐ Great
*by J***Y on August 10, 2020*

Great product

### ⭐⭐ Poorly designed
*by R***M on October 18, 2020*

The circuit is poorly designed and exceeds the transistor ratings causing it to fail. Apparently the board was layed out for a different transistor as the D882 has the base and emitter reversed and has to be mounted with the heatsink on the wrong side rendering it almost useless. There are no instructions or even a schematic. The transformer has two unmarked windings, a heavier primary and a finer feedback, so you have to figure out polarity yourself. I used the transformer in another project with a completely different drive circuit and it worked well for a spark ignition system, so I got some use from it.
