Description: High quality switching ‘wall wart’ AC to DC 9V 650mA wall power supply manufactured specifically for Spark Fun Electronics. 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.
Works with 100-240VAC inputs.

Shipped fast and works great!
I just powered up 160 Arduinos with these power supplies with no issues!
I have a 9 and 12 volt version of these , both work excellent with decent cord length. Ive been playing with lm386 amps and these make excellent power sources
