I found few and differing information about a power supply.
I plan to use my Keyboard for pure midi usage, so no usb powerd action possible (or, can I use a phone charger with a USB plugin, like eg. for a smartphone? How much mA does it provide)
I need to know, if the keyboard needs 1500mA or more/less?
Also, not all power supplies have different adaports, is a a classification for the size of the DC in?
Thank you very much!
