6ft Extra Long AC Adapter for Casio CTK-573 CTK-591 Keyboard Wall Charger Power Supply Cord PSU

Works with no issues. 5 stars, but I didn't receive the double-sided Velcro cable tie, which would be handy to have to keep the currently excess cord length bundled. Usually one end of the Velcro tie is fastened around the cord, so it doesn't get lost. Also, Velcro ties last longer than wire ties, for me at least.As others mentioned, the blue LED is a bit bright. I plugged the adapter into a power strip, which is plugged into a wall outlet, and use the power strip's switch instead of the piano's power switch. Another reason I used the power strip switch is that my piano's power switch is a bit loose now.The AC power prongs/plugs on the adaptor are oriented so that the adaptor doesn't cover other outlets/ports, particularly on power strips.

I had tried a universal power supply and it didn't work. This one is working perfectly. They were very fast in shipping and it came on time.

Works well with my old Casio keyboard

After plugging it in a few times, the box and codes came completely disconnected from each other. The cord itself worked well until it fell apart.

It powered my old 30 yr Casio keyboard perfectly! I had misplaced my old adapter.

Works perfectly for my Casio. Only complaint is that the light does not go off when plugged in and it’s very bright, just as a heads up for anyone that would bother.

After buying another one and returning it- I found this one and it works perfectly on the casio ctk-591 that I got at goodwill for 9.99

Fits our ctk-573 perfectly. It glows with a constant blue light when it's plugged in though, which gets annoying at night. We have to unplug it before bed.

After trying several others , this one is the only one that worked for my older Casio keyboard. Very happy

I lost my original plug and this one works great. Delivery was a bit slow but all good now
