{{main|USB Killer}}
Similar in appearance to a USB flash drive, a USB killer is a circuit which charges its [[capacitor]]s to a high voltage using the power supply pins of a [[USB#Connectors|USB port]], then discharges that voltage through the data pins. This standalone device can instantly and permanently damage or destroy any host hardware that it is connected to.<ref>{{cite web
