Members mrejk Posted February 5, 2010 Members Share Posted February 5, 2010 The fast track pro needs a 9v DC 500mA. Would using a different power supply hurt it? I have a 9v DC 850mA power supply and another one that's only 200mA. Link to comment Share on other sites More sharing options...
Members ashasha Posted February 5, 2010 Members Share Posted February 5, 2010 Use the bigger one, make sure that the polarity for the tip is correct and you'll be fine. It's only a problem when the polarity is wrong, the voltage is wrong or the current is too low. The device will only draw as much current as it needs.
