This things got an arc over an inch long. From a nine volt battery. That's gotta be a pretty hefty P\I=V thing. Nine volt batteries have pretty small cells. It doesn't seem to take much time to charge either. It's almost instant.
400kv at 5mA. I dunno. I'm having a hard time beleiving this thing even works. It seems like free energy or something.
They voltage varies depending on model and manufacture. The X26, commonly used by law enforcement, puts out 50,000 volts and supposedly operates at a frequency that is close to the human body?s electrical system.
