USB KILLER is out to destroy your computer.
This USB stick is basically directly out of a sci-fi movie. The device is appropriately named the USB Killer because it will fry your computer out of existence. It might be a small device, but it sure is a deadly one.

According to the manufacturers, demand is seemingly high due to back orders. This tiny little monster can be yours for just $49.95

"When plugged into a device, the USB Killer rapidly charges its capacitors from the USB power lines. When the device is charged, -200VDC is discharged over the data lines of the host device. This charge/discharge cycle is repeated many times per second, until the USB Killer is removed.
Simply put: used on unprotected equipment, the USB Killer instantly and permanently disables unprotected hardware."

I wonder about how it is made, looks like a dc-dc boost converter to me but I'm not sure.
