Comimark 1Pcs DC12V to 20000V 5W High-Voltage Electrostatic Generator Negative Ion Generav

i actually never used it in a project.

Works for a bit, but burns out after a few uses. Bought 2 and both have since stopped working just after 20 or so runs! 12V input was const per guidelines.

Get it? Because it shocks you? I used this to make an electrostatic precipitator, but in the process I also made a lot of arcs and coronas. I can verify that it's definitely making negative ions (and ozone) and it does so without getting hot or anything. It can be safely powered from a lithium ion pack and a 12V buck converter.

The resin it was potted in was all sticky and gooey, and it burned out after 5 minutes of use. Seller should specify that it's not meant for continuous function. Either that or maybe it's not meant to run at 12 volts. The packaging didn't specify 12 volts only the product listing did. I didn't try 5 volts to see if it would work but if you get this module try it at 5 volts first and see if that's good enough.

I ran it at 12 V one amp creating a static charge and it worked for about three days. I’m not sure why it stopped by the time I got around to using it. I think third turned date had already passed and to be honest I have a habit of not bothering when I view it as not “significant “it seemed good quality. I’m not sure why it died I just probably wouldn’t purchase this one again.
