Package Included: power adapter 30W [Center Negative Version]8 DC TipsHow Can we distinguish the Correct Polarity?You can easily recognize Polarity by looking at the symbol near the DC power input of your device. It's that barbell looking thing with a + and - on opposite ends. If the center "c" shape opens to the -, it's negative polarity! (the + is on the outside and the - is on the inside), buy this adapter. If it's the reverse of that, buy one with the correct polarity.

Review: Works fine - Powers up equipment fine . Just don't get the polarity mixed up
Review: Saving batteries - I have an old tape player and a ton of Prairie Home Companion radio shows I taped and haven’t listened to in years. I couldn’t find the cord for the tape player and I wanted to save on its batteries. This was the perfect solution! Works like a charm!

### ⭐⭐⭐⭐ Great power supply but adapter didn't fit my Casio Keyboard
*by N***X on August 20, 2024*

I was looking for a power adapter for a Casio CDP100 which requires a 12V 2A non standard negative center pin. This power adapter has the ability to switch voltages which was great and it also comes with a number of connector to fit different hole sizes. Unfortunately the CDP100 power connector hole is very non standard and requires a short connector. This power supply did power the keyboard but slight movements would lose connection. Still rating this adapter high but a different connector is needed for the CDP100.
