Hey There,
I have a music keyboard which can be powered via USB. I would like to buy a usb wall power adapter so I can plug it into a wall and not have to have a keyboard around. Will this work if I buy a USB wall adapter for an iphone/ipad or something like that? Because it seems to me that when devices are powered via usb they draw only as much power as they need, as opposed to a wall unit which would just give a constant stream of 5V and 500mA. So I am worried that my keyboard might not need a full 5V or 500mA, and may get damaged by using a wall adapter.
Can someone tell me whether this will work or not?
Thanks!
