okay Friends so this is my pc and i’m going to test our DIY USB killer on it so let’s see if it works and how powerful it is so here we go so so almost done …to set up ok so here we go guys 123 (Crackling Spark Sound) oh my god ! it really work as you can see my pc is not working oh my god ! so to make USB Killer you need any kind of High Voltage Generator you can use anything like thi mosquito killer bat (Bug zapper) or you can use a dedicated once like this you can get on ebay but we are looking for a really simple USB killer now there is a product that is sold as a USB ionizer and that is actually a USB killer so this is a USB air purifier or USB ionizer sold for three dollars and the inside you’ll get this one now this is actually a USB killer !!! so let’s see with a simple modification of one wire you can make it a USB killer so to open it up you have to remove this outer clip by just doing that and with the help of screw driver you can easily able to remove this to side clips the silver ones our side clips are removed now you have to gently lift this Clips right here these are three clips and you can easily able to remove it now out-of-the-box this ionizer circuit is not a perfect USB Killer contains all of the elements that USB killer has now onto this side there is a high voltage generator circuit so we help remove this output wire by desoldering it so get your soldering iron and desolder it there is a rsistor right here and you can easily locate at this capacitor at the output and solder one wire at this side so there it is now it is connected and let’s test of how much big the sparks are as you can see it has a lot of energy in these sparks now we need to connect this output wire to pin right above the ground while this wire is the data negative now this USB ionizer will work as a USB killer ! although the power is enough to kill any pc or smartphone you can also increase the power by replacing this small npn transistor with alternatives right her . Now to make a USB Killer tester get this USB male and female port connect their 5 Voltas and ground (Negative) together like this get a proper rated metal oxide varistor (MOV) and install them onto the 5 Volts line short-circuit the data lines of the USB femalel port connect the output wire to the ground and the shorted data lines and your USB killer tester is ready so let’s see how this DIY USB killer and tester works . Now I plugged in the USB Killer through the killer tester so as you can see now the high voltage can be safely discharged through this USB Killer Tester and if I remove this and plu it in i’m sure this power bank will die so that’s how this works Guy’s Good Bye ! that PC Was… Good Man ,Now It’s Trash !
