9V AC / DC Adapter For Casio Model AD-5U CZ CT MT HT HZ SA Keyboard Power Supply $9.99 + $5.99 shipping PwrON AC Adapter Charger for Casio CTK-558 Piano Keyboard Power Supply Cord PSU. I have an old CASIO CT-636, which works with 9V adapter, OR 6 D-size batteries. It does not come with an adapter, you have to provide one, and make sure it can switch to negative-inside, positive-outside - which is the old standard of the barrel jack. I thought it would be nice to make it work with a normal power bank.
