Hello, I'm a bit confused. I thought the max. would be 1 Amp the Freerunner can be charged. But on pulster.de which are selling the offical usb-charger for the freerunner is written that it can be charged with 2 Amp: http://pulster.de/d__omnetz__Openmoko_Freerunner_Netzteil993.htm . What's now the correct value?
