## Questions & Answers

**Q: 850 milliamps 9 v ac adapter I need**
A: This one worked as described for Casio key board which also needed the 850 9v ad-5 adapter

**Q: Will this work for CTK-541 keyboard???**
A: Yes, this should work.  The CTK-541 specifies Casio's AD-5 power supply and this is a replacement for that model power supply.  I've purchased about 5 of these so far and used them with a number of different Casio CTK models that specify the AD-5 and they work great.

**Q: Does this work with casio sa-76 44 key mini keyboard?**
A: Sorry about that it can't works for SA Series,it require 9.5V Adapter.

**Q: will this work with keyboard ctk-491?**
A: It works with my Casio CTK-471. If you look where the MIDI In/Out, headphone jack, and AC input is located it should say the input voltage above where the plug goes. If it says 9V you're good to go.

## Customer Reviews

### ⭐⭐⭐⭐⭐ great little psu for use with a musical keyboard
*by R***S on January 8, 2021*

this does exactly what I expect and all 12v and 9v power supply's that have a price tag between $5 and $10 are in "normal price range" never pay more and always look for "further discounts and coupons" at the end of the day a power pack is inexpensive metal and a chunk of plastic that you can NEVER break open so when it dies it is in the bin ( or trash as the USA people say ). several months in, this one is working fine.

### ⭐⭐⭐⭐⭐ Works for a Casio CTK-800 keyboard
*by K***N on March 11, 2016*

I got this power adapter to replace the one that came with my Casio CTK-800 keyboard and that had gone MIA in a move. I didn't want to pay 20-30 dollars for an AC adapter and for ten bucks this one works. The cable is long enough to reach an outlet as I keep the keyboard on a stand. A red LED indicator light on the adapter illuminates when it is plugged in. What else can I say,but the plug fits the keyboard, it powers the thing and it works.

### ⭐⭐⭐⭐⭐ perfect for my casio keyboard!
*by K***R on January 20, 2022*

I bought a casio keyboard without a cord, bought this! Works perfectly and lights up a nice blue to show its got power.
