Summary: This item has to be purchased separately -it was not included with the Yamaha keyboard my wife and I selected as a gift for our daughter - which common sense dictated was a must have rather than depending on batteries. This turned out to be a good decision because batteries aren't included with the keyboard either and our daughter was able to plug in the adapter and start playing right after opening her gift.
Summary: The Yamaha PA150MM Keyboard AC Power Adapter sold by Amazon (as opposed to a vendor partner) is not a Yamaha part at all. The transformer is the one pictured, but there is no picture of the label that would make clear that this is a generic product. Having noted this, I must admit that the transformer apparently works with my keyboard. However, the cord on the adapter is no longer than two feet.
Summary: Would have preferred the Yamaha PA150MM Keyboard AC Power Adapter, instead of the equivalent item which I was sent. Don`t know if this product fits as an acceptable replacement part for keyboard.
Summary: I misplaced the original power adapter for the Yamaha P-85 digital piano. I was not only surprised to find it at Walmart online but at a much lower price than all other competitors. Because it was new it was a little tricky to plug it into the keyboard. But once I did I left it set up and plugged in.
Exact replacement; worked the same just smaller in size!

Summary: Exact replacement and worked well. My daughter dropped the old original brick adapter for her Yamaha keyboard. This one is an exact replacement but just a lot smaller. Worked well and a great price on Amazon.
