9V Power Adapter fit for Casio Keyboard AD-5 AD-5MU WK-110 WK-200 LK-43 LK-100 CT-360 CTK-496 CTK-573 CTK-611 CTK-700 CTK-710 CTK-2100 CasioTone Piano Keyboard Power Supply Cord

I tested this adapter out on my Casio CTK-710 from 2006, and it works perfectly. Comes with three converters for different size plugs, I had to use the biggest one.

I bought this for a Casio keyboard I gave to my grand daughter that had to use batteries. Now she can plug it in. It also works for a portable guitar amp that I got her.

Worked for portable piano

Lost the original plug in adapter for my keyboard so I purchased this one in hopes it wold fit and sure enough, it is a perfect fit and keyboard is working again. Good product 👌 very pleased

If buying for CTK-511 a/OR to replace 6 D batteries, it does work. 3 joints included to find best fit, plus option to plug standard joint directly into port- so that's 4 total fittings. Fit is a little loose, so that's why 4 stars, but no evidence loose fit impacts function. Also, would be nice if cord a bit longer, but you could get an extension cord. Happy playing.

Great Construction - both electronic and physical. Good price. Met or exceeded my Casio Keyboard's power requirements. Runs very cool under maximum load.

This adapter came in an open box. It was very obvious it had been used and returned. The inside packaging as opened and the cord unraveled. It wasn’t in the bubble wrapper in the box. The adapter doesn’t fit properly. It is extremely loose where it plugs into the keyboard. Very disappointed!

I bought this because it was the listed replacement for my old Casio CTK-800 which would only power on with batteries. It still only works with batteries so it has to be an internal wiring issue.
