I've noticed a lot of people here were having a hard time finding the right adapter for their specific keyboards, and I've got a solution. You don't actually need to buy a Casio brand adapter to fit your Casio keyboard (matching model numbers can be tricky online). Here's a fool- proof method for finding the right adapter every time;

On the back or underside of your keyboard, there should be a voltage rating (which looks like a number followed by 'V'. For example, '9V' or '8V') and a milliamp rating (which looks like a larger number followed by 'mA'. For example, '850mA' or '900mA').

With those two numbers, you can find the exact adapter you need. :) For example, my keyboard is rated '9V 850mA', which looks like a bunch of gobbldeygook until you type it into a search engine or show it to a salesperson at any electronics or toy store. Almost all adapters are rated this way and regardless of the manufacturer (i.e. Casio, Yamaha), you'll always get the exact adapter you need when using voltage and milliamp numbers. Just be sure the other end of the adapter is the right fit for your input jack, and you're all set. :) Hope that helps.

I have a very old Casio "Bank Tone" CT-636 portable keyboard. The AC adatpor was lost and I've been using size D batteries for my son to play the keyboard and that was getting expensive. Finally searched online to find a replacement AC adatpor. According to the spec at the back of my CT-636, it says "DC 9V, 4.5W, uses AC Adaptor AD-5". 9V 4.5W translates to 500mA.
I found two such AC adaptor links on Amazon. One says AC Adatpor AD-5. Another says AC Adatpro AD-5MR (9V, 850mA). Since I didn't want to deviate from the spec and the product description for the AD-5 on Amazon included my model (CT-638/CT-636) while the AD-5MR didn't, so I ordered the AD-5 (~$19+shipping) even though it was almost $10 more expensive than the AD-5MR (~$11).
The delivery was super fast. I got the AC adatpor 2 days later. HOWEVER, this AC adaptor shipped is actually the AD-5MR (9V, 850mA)!! I plugged it into my CT-636, yes, it works, but had I known they are going to ship me the AD-5MR anyway, I would've order it $10 cheaper!! So i was not happy about that.
I gave it 4 stars for the fact that it works.

As the last reviewer wrote, we also ordered the adapter to go along with the keyboard we ordered and held both items until Christmas. The adapter was not the proper adapter for the keyboard as pictured.

We bought also the keybord and the adapter (as recommended) and it does not fit. I already tried to buy a new one, but it is not available.

I got a Casio keyboard for xmas, and, considering it's size and quality, I was a little disapponted that it didn't come with a power supply (integrated or external (integrated would've been better)) but the next day I went to Toys R Us and bought this little gem and now all is fine.

There seems to be a bit of confusion surrounding this adapter, mainly people having bought it for a keyboard it doesn't support. According to the pack, it "fits all CT, CTK & LK Keyboards except LK6". It works great on my LK-50. Another reviewer mentions getting a generic 9v adapter - I have tried 5 which fit, and all but one of them produced a buzzing from electrical noise. The one that worked ok was an adjustable power supply I use on a radio, but it's only 500mw. Save yourself the hassle, if you have one of these Casio keyboards this is what you want to get.

I, like the other customers. ordered this adaptor based on the recommendation from the site, and was disappointed when, on Christmas Eve, I realized this was not right for the keyboard we had ordered. This situation was particularly misleading since the adaptor was practically "bundled" for sale with a product for which it is not compatible.

When I ordered the Casio SA-67 keyboard on 11/05/02, I also ordered the Casio AD-5UL AC adapter at your recommedation, along with other items. I held the items till Christmas for our grandson when we were disapointed to find that the plug on the AD-5UL adapter was too large for the DC7.5V jack on the electronic keyboard. The keyboard user's guide clearly specifies the model AD-1 as the only AC adaptor to be used with the SA-67 keyboard.

This adapter is for many of the older "Tone Bank" Casio keyboards, mine is a CT-640. This saves the cost of changing six "D" batteries on a frequently used keyboard.

Amazing, I read all the reviews and "assumed" the problem with the wrong adapter was resolved since reviewers have complained since 2003. I ordered the Casio CTK 691 keyboard, clicked on the recommended power adapter and trusted the folks at Amazon knew which model I would need. Wrong, it doesn't fit. Since we bought this keyboard to travel this summer it has been very inconvenient, and we haven't had time to resolve it.
