There's no way a USB cable would support 120v, it would melt almost instantly the minute it touched anything.

Thats right Josh, cables are rated for voltages, not amps
Fortunately he is better at his job as COO and 2 weeks after the original promised shipping date, he is clearly on top of things:
".. I still don't have all the information I want to make a specific statement on who's affected and who isn't, as I don't know exactly how many chips we are getting in the first batch. .... I'm not making any commitments, but I'm going to hazard a guess ... With the bullet run being delayed, it may end up that we get all the chips ... I really hate making comments like this, because they get taken as commitments and that is absolutely not what this is. It's me speculating without all the information I need to make a firm statement."

Don't be a pedantic idiot, Puppet. The guy was claiming that it shocked him and that it was plugged into his Jalapeno and also blew out the rest of his equipment... which would mean the wire would have to carry enough amps to do that, meaning it would melt @ 120v. But you already knew that, right? You just wanted to post yet another troll with your worthless, utterly idiotic, mind numbing stupidity.
In short: You're a moron, please go back to your drooling sessions with the rest of the idiots and leave the adults alone.
