Produces high-voltage sparks of more than 10.000 V from a 9 V battery which may go through clothes, too. Ideal as self-defence weapon against wild animals etc. or may be used for physical laboratory experiments. In several countries (e.g. in the EU) the possession as a weapon is prohibited. A deterrent effect is already achieved through the sparks flashing over and the sparking crackle! Operating voltage 9 V/DC Current consumption approx. 160 mA Output voltage max. 10.000 V Frequency of sparks > 3 sparks per second Dimensions of the board approx. 65 x 56 mm
