Re: Not to be mean but,
It won't work with properly compliant cables and chargers that provide dual cc-line. The way the Pi is wired, it advertises itself as an audio device, and so chargers/cables that detect how a device is advertised will not send power to it. Cheaper cables don't detect, and always send the power.
Ward's original blog post describing the issue explains it better, I'm probably misdescribing something.
