Review: The missing like to power guitar pedals - Works great ...finally can power my tonex pedal from my power bank via USB and a USB C to DC adaptor cable. You need this converter cable to make it work, just the USB to DC cable won't cut it. Guitar pedals are center pin negative. Solid connection and great quality cable glad I got the 2 pack.
Review: Use a standard power supply with nonstandard electronics - Needed this for a Casio keyboard, bought in a thrift shop with no power cord. I have lots of 'em with the right voltage, but Casio uses a nonstandard polarity (presumably to make us buy their proprietary power cord). This adapter changed my standard polarity cord to fit their keyboard. Worked great and saved me $20!

### ⭐⭐⭐⭐⭐ Just the job.
*by O***A on 18 July 2026*

I sometimes film football matches, no problem when there is mains power but if not then I have to use the camera batteries. I also use a 9" monitor that comes with an in built battery that unfortunately never lasts the full 90 minutes or more. I recently found in my video gear a separate back up battery for an old monitor that was the right voltage so I tried it with my 9" monitor but it just didn't work, I knew it was charged up so just thought for some reason it was not compatible. I then thought perhaps the plug was the wrong polarity so I bought these thinking they probably wouldn't work and bingo the one the correct size did. Wish I had known about these before, absolutely brilliant.
