MaxLLTo6ft Extra Long AC Power Replacement Adapter for Casio WK-110 WK-200 WK-210 WK-3700 Keyboard Charger Power Supply Cord

no issues - I found the perfect yamaha musical keyboard cheapy power pack that is solid and I give them away whenever I sell a yamaha. THIS MAXLL I always purchased when I fix and repair or sell Casio WK 1xx 2xx models and some of the 64 key models that use the smaller "reversed polarity" psu.

Well priced adapter , does what it should .

Have been setting up a project home studio and discovered that the power cord to my Casio WK-200 was missing; ordered this replacement, it came within days and powered the keyboard right away. Seems to be supplying the right voltage as all the keyboard options are working fine. Just ordered another one as it works also on a Korg DP-80.

The plug came in timely and was a perfect replacement for our keyboard. No problems with polarity, we plugged it in and were up and running. The extra long cord is nice as the outlet is a little distant from the keyboard.

This worked for our Casio keyboard that was using just batteries. This so much better to use this and save on those battery costs. Powered right up and made beautiful music! We had no problem, fit like a glove. We would purchase from this company again!

The plug fits fine, and the keyboard operates without a hitch using this adapter.

It's a replacement charging cable. How much could I write? I will say that it is the best deal. We went to all the local electronic stores and they wanted to sell is some very expensive replacements. Even buying this one as a rush order was a better deal.

6 ft works for me but for others that need more than 3 ft to work with, they will have to use extensions.
