Killer USB? ?

I ordered a custom electronics kit from a company I trust, and it works great as per usual. However, I also received an envelope marked with “killer usb, do not use.” I plugged it into an old WinXP e-machine and sure enough, it died immediately. Should I report this?

    Those are a well-known gimmick.

    The safest thing to do with it is to smash it to ensure no one connects it out of curiosity.

    [They have a capacitor bank and voltage inverter, that charges the caps to a high voltage using the 5V from the USB socket - and another circuit then connects the high voltage back to the USB pins once it's built high enough, overloading the motherboard protection and causing damage.]

    Why did you use it when it said not to use it. 

    I guess you can complain about sending you the killer usb but ultimately, you’re the one who used it.
