This 9v power supply is a genuine Casio and designed for numerous models of keyboards. Your keyboard should have printed next to the power source socket the voltage but I think most of them will take up to 9v apart from some of the smaller ones. There's some marks in places but no damage or major faults. Overall it's in fair used condition and still has plenty of life left in it. Fully tested and working too...Check out my shop L555_BAT for more interesting items. We dispatch on the same or next working day depending on what time you pay. Sorry no collect in person, all items are post only even if you're local.
