Contained power supply

So now I can just make something clear. namely've bought this keyboard at random. For I have asked myself whether the keyboard with power supply or battery operated and whether a power supply is attached. So I'm glad I bought this keyboard it does not contain a power supply unit, a microphone, however the the best quality but was for beginners, it is sufficient in any case and a music stand is attached. The keyboard can incidentally also be used with batteries (6x R20). So to me there's a full five points as the keyboard and the included accessories are really great for those really cheap price. The delivery of Amazon worked the way super've ordered Tuesday 23.00 clock and the package was Thursday already there.
