9V AC Guitar Pedal Power Supply Adapter Compatible with Boss PSA Series, DS-1 RV-6 TU-3 BD-2 CH-1 GT-1 RV-6 CS-3 MT-2 SD-1 MT-2W ME-80 GT-100 DB-90 (10FT)

Works fine. Runs cool, don't have to think about it. Great bargain, the two of them. Bought the other simply as an extra, and the fact that Boss and other music things use this voltage with a negative tip which is not all that common hanging around the house, even if you save every little power supply from old equipment.

Wow! Very small and light! Not your average wall-wort. In the ad, the cable appears split/dual-band type. I was hoping for a single, more flexible cable ... and low and behold ... it comes with a single round flexible cable. Retailers (product designers?) BENSN are from Germany, I read on inner packet, product made in China.

Never had a DC power supply for my Casio and wanted to prevent damage to my electronic keyboard by leaking batteries. This device was the size recommended on the Casio site for my keyboard and works great and don’t have to be dependent 5 heavy D cell batteries!

very stable voltage, low noise, green power-on LED is very useful

Love the long cord & knowing we didn’t have to go over the place for it!

Works fine. I like the 10ft cord. A good value!

I took a chance with buying this adapter as a replacement for the Casio AD-5U AC adapter for our old Casiotone MT-210 musical keyboard, and it works!

I had another adapter that didn't work. Once I plugged this in, my Boss OC-5 turned on.
