Price of the Freerunner spare parts

Thanks Kevin,

  I recall asking engineering what would happen if somebody disabled this
check ( hey its open source) and the general impression was that if the
charger was not capable of fast charging then you would not have nice
outcomes. I think the worse case might be if you tried to draw more than
500ma from a PC USB. Somebody not in marketing should answer that question.

This is possible via userspace with Bobby's application.

However, the flaw to this is that it will force fast charge even if
the charger isn't capable and hints that this could be... bad. :)

For the record, it APPEARS that with the Python application, the iGo
works just fine as a charger.
