Robotbanao High Voltage Step-Up Power Supply Module DC 3V-6V to 400kV(400000V)-Electronic Demonstrations And Experiments-High Voltage Generator-Multicolour Wires

First of all, those who want to buy it for experimental purposes, like EMP or taser, this thing is absolutely amazingBut never ever use a 9V battery. This thing is so powerful that it can drain your 9V 6F22 batteries in a few minutes. You should try it with a continuous source that doesn't discharge, like a phone adapterHowever, be careful that even with 9V battery this thing can give you a shock of about 300V. This thing isn't a toy and if you use it for experiments, you should be aware of what you are doing.5 star experience. Just a small concern that the company should also mark the output wire jacket so that you do not have to check the polarity every time you use it.

Working.

Nice product, excellent work

Nothing works 😔

Good product

Batteries very good high voltage are you stupid for machine making good you should buy this if you are interested in in this type of works

Product is definitely worth the price . Do use a lithium battery of 3.7 volts for the best results. Be careful of the spark, it can give one of the nastiest electrical shocks.
