Description: High quality switching ‘wall wart’ AC to DC 9V 650mA wall power supply manufactured specifically for Spark Fun Electronics in retail packaging. These are switch mode power supplies which mean the output is regulated to 9V (no more 14V outputs!) and the 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.
Note: This adapter works with 100-240VAC inputs.
