USB killer

A USB killer is a device that is designed to be portable and sends high-voltage power surges repeatedly into the data lines of the device it is connected to, which will damage hardware components (integrated circuits for ADC/DAC providing transmission) on unprotected devices. Companies selling the device state it is designed to test components for protection from power surges and electrostatic discharge. Various overvoltage protection devices may be employed to make lines more resistant to high currents.
