3Pcs DC 6V-12V to 1000kv 1000000v 2A-5A Boost Step Up Power Module High Voltage Generator DC Transformer Converter Coil Module

These are great for displays.

These ran fine half of a half didnt Main for battery. Even hit my arm once and it was the worst pain I think ive ever felt in my life. This brings up the safety issue though, when you have high-voltage capacitors Capable of storing terrifying amounts of electricity, It is not uncommon to see your sister across the two pause in the capacity to allow a slow bleed down so as to prevent injury from accidental contact across the two leads. These coils DO NOT contain any current bleed down device as youll notice after the arc extinguishes, the secondary wires will give one final “pop” if shorted together after de energizing. Be careful!!

used as a ignition source on homemade weed and army worm burner, these little guys have some serious punch, almost bone chilling to hear it crackle. tried some others and these are nasty, highly recommend don't kill yourself with them

I purchased three of these. 1 was DOA . 1 worked for about 1 min and the other about 3 mins. After reading other reviews I determined that they WILL NOT handle 12 Volts. I ordered 3 more and will try at 6 volts.

Stopped working after just a few discharges.
