Casio CZ/ VZ/ FZ - Pro Series

The CZ-101 requires 5.4 Watts (per the underside of the unit) at 
9Volts DC. That would be 600 Milliamps draw (Watts divided by Volts 
equals Current). So anything from 600 Ma and up would be suitable. 
You might slide by with 500 Ma but anything lower than the minimum 
required current can leave a device inoperable or unreliable.
