It‘s a good quality switching ‘wall wart’ AC to DC 9V 1000mA wall power supply. This is a switch mode power supply which means the output is regulated to 9V and the capable output current is much higher up to 1000mA.
This will power most of your projects that don’t require more than 1000mA of current. It has a center-positive 5.5×2.1mm barrel connector.
