The 9V Wall Adapter Plugs for Arduino is a high-quality switching 'wall wart' AC to DC 9V 650mA power supply. The switch-mode power supply regulates the output to 9V (no more 14V outputs!) and its capable output current is much higher (650mA). These will power most projects that don't require more than 650mA of current. Center-positive 5.5x2.1mm barrel connector. Perfect for the Arduino.
