How Do This USB Killer Device Destroy Your Smartphone or Computer?

Thomas Kim homemade USB Killer device supplies 300 Volts surge to the computer or smartphone that its been plugged to and 300 Volts is more than what a computer or a smartphone motherboard can handle, so the result will be frying your computer or smartphone motherboard.
