hello a person shares the gerber file to make the printed circuit
no, we don't need more of this bullshit. This is vandalism, pure and simple
I have two of them. I ordered them only to give me a technical challenge to design an extreme USB port protection circuit. Unfortunately, I found sabotaging is the only possible use case here. They're useless for actual testing.

This is why I went to design an actual, proper IEC 61000-4-5 surge generator for my lab instead.
When a 50 Ω load is connected, it keeps pulsing continuously, peak voltage is typically 140 V, but can be as high as 200 V. Pulse width is about 100 μs to 250 μs. Repetition rate is about 27 pulses per second. The pulse characteristics are poorly controlled. If you don't disconnect it quickly enough, after continuously pulsing for a minute or so. It can no longer generate continuous pulses, and the pulses were no longer as powerful anymore. There's permanent circuit damage - Understandable, given the seriously undersized SMD components to fit inside a USB stick enclosure.
In other words, the USB Killer eventually kills itself for good.
