- Casio AD12 AC Adpater Power Supply

Good product

Pulled it out of the box and plugged it right into my WK-3500 keyboard; worked like a charm. The only issue I have is that this is actually a 2-piece AV-adapter: There is a small wall plug that runs to the power brick, which has a plug socket on it. The cable that runs to the keyboard has to plug into the brick. It's really not a big deal and it works just fine, but the picture doesn't accurately represent the product.

Note: when I purchased this I selected Amazon LLC as the seller (there are multiple sellers on this product page). The power supply I received is a genuine Casio OEM product and works perfectly with my Privia PX-320. I awarded it five stars because it is identical to the original power supply that was bundled with my PX-320. I tested it for overheating and other potential problems before storing it in my spares bag. One thing I dislike about this and other Casio power supplies is the fact that the cable is pretty thin, That is the reason why I ordered this one as a spare in the first place. I also compared this to some third party power supplies that were supposed to be compatible. I opted to pay the premium price for this one just for peace of mind. I may order one of the other third party ones to evaluate it now that I do have a viable spare, but in the meantime I do not regret paying extra for this one because I cannot afford to have a malfunction at a gig.

Do not buy it for Casio Keyboards, it is not compatible and won’t power your keyboard.

So glad I was able to find this in stock. After a severe thunderstorm my keyboard stopped working. It was not plugged into a surge protector (I know, I learned my lesson the hard way) and I was really worried that I would have to spend close to $500 on a new replacement keyboard. I went to Guitar Center where I had originally purchased my keyboard to see if they had any adapters in stock. After OVER A MONTH of waiting for a replacement adapter from them, they told me it was now on back order. I was so fed up with being tossed around that I finally looked on Amazon for one. (Don't know why I didn't think of that in the first place.) I was so relieved to find this! I was slightly skeptical after reading a couple negative reviews, but for $30 I figured it was worth a try. I couldn't be happier! This adapter came just as pictured with a short extension cord. I plugged it in and my keyboard turned on and works with no issues whatsoever!

I'm not really sure why, but the cat occasionally eats a power cord or two of mine. I mean we try and get along. I feed her. I really feed her more than I should. I pet her and brush her and she lives right in the house and has a ton of toys and everything. I thought that we had an unspoken agreement (she cannot talk) wherein she gets treated well and fed regularly and she doesn't ruin any of my stuff. Despite these attempts at inter-species peace. I tried to play the piano and the power wouldn't turn on. Lo and behold the cat struck vengeance on that cord like Mark Wahlberg on crooked cops. Anyway, got this replacement cord and it works great. Probably a little better in size and overall clunkiness than the original. I set up the new cord with ease, like lambs to the slaughter.....

After going thru boxes of adapters, none fitting, I bought this for my wk 3700 , it got here in like 2 days, so I'm impressed and happy. I bought a cheap adapter, because my son also has the same board, well, the good one can stay here and the other taken to rehearsals. Saved a few bucks, and there's this nifty "extension" to hold the part of the power cord that goes to the wall.

I accidentally ordered two adapters. The first one which arrived was the wrong adapter but I don't know if it was my fault in not reading carefully which model keyboard it was for or whether the description lacked clarity as to which model it was made to fit so I went down to Radio Shack and bought one and threw the one I received in the junk. A few days later the second adapter arrive and that one was the correct size so now I have two adapters--one which I ordered from you and one which I bought at Radio Shack.

It came. To install in to my Casio Keyboard, I had to figure out why I had no power at keyboard. 1) First was 120V outlet had bad contacts. 2) The contact pad of the Jack inside of the Keyboard was bent. Took a little bit of work to get the contacts to touch the power adaptor plug.(I completely disassembled the keyboard, only to find that I could have fixed the the bad jack with a tiny pick tool) (reason here was we where using another non-standard power adaptor, and its plug was a smaller size. I guess my son had bent the jack after inserting and removing the plug in the last 4 years. New propper Casio adaptor works.

Good but expensive

Now i'm using my portable keyboard without any problem. It's Casio's excellent quality as always.
