I have a z64 that I'd like to begin using ... but I do not have the power adaptor. The unit says 5V input on it, but gives no other details. So ... I was thinking of this: [h=1]Hosa ACD477 AC 100-240V Multi Voltage DC Adaptor[/h] http://www.amazon.com/Hosa-ACD477-1...1G3M/ref=sr_1_1?ie=UTF8&qid=1335823368&sr=8-1 It can select 4.5V DC, and has 1200mA max ... reasonable ? I really don't want to fry the z64
