Did you actually try this yet, and did it work? I just bought a car-charges which is supossed to be able to provide over 2A, but the freerunner will only pull 100mA which is annoying. A related question, the freerunner wil detect a 47k resitor in the official charger. Is this value measured and available in software somewere? We might be able to identify other chargers as well and build a database of ID resistors and allowed current (assuming other vendors use the same trick).
