Review: 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: 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! ## Features - One male plug and one female plug - Reverse Polarity what you want, fit for keyboard and guitar effect pedal - Length: 173mm - Jack Size: 5.5mmx2.1mm - 1pc Effect Pedal Cable ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07YJKJY7C | | Best Sellers Rank | #15,051 in Electronics ( See Top 100 in Electronics ) #3 in Music-Making Power Cables | | Brand Name | Mr.Power | | Cable Type | Jack | | Color | Black | | Compatible Devices | Keyboard, Guitar Effect Pedal | | Compatible Phone Models | No Compatible Phone Models | | Connector Gender | Male-to-Female | | Connector Type | Male-to-female | | Customer Reviews | 4.7 4.7 out of 5 stars (161) | | Indoor Outdoor Usage | Indoor | | Item Shape | Round | | Manufacturer | Mr.Power | | Model | MP-RPC-5521-2 | | Number of Items | 2 | | Number of Pins | 2 | | Other Special Features of the Product | Tangle Free | | Outer Material | Plastic | | Recommended Uses For Product | Connecting musical instruments | ## Product Details - **Brand:** Mr.Power - **Cable type:** Jack - **Compatible devices:** Keyboard, Guitar Effect Pedal - **Connector type:** Male-to-female - **Special features:** Tangle Free ## Images ![Reverse Polarity Converter Cable - Image 1](https://m.media-amazon.com/images/I/41Ke6H0swzS.jpg) ![Reverse Polarity Converter Cable - Image 2](https://m.media-amazon.com/images/I/51Xbq9ichzL.jpg) ![Reverse Polarity Converter Cable - Image 3](https://m.media-amazon.com/images/I/51DCPj3KfHL.jpg) ![Reverse Polarity Converter Cable - Image 4](https://m.media-amazon.com/images/I/6122xcUuR9L.jpg) ![Reverse Polarity Converter Cable - Image 5](https://m.media-amazon.com/images/I/61bjpaMyONL.jpg) ## Questions & Answers **Q: Does it work with 9 volts** A: I use it for 9 volts.

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 *by K***Z on 4 February 2026* 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! ### ⭐⭐⭐⭐⭐ Review *by O***A on 24 September 2024* I purchased a multi adapter and I wasn't able to use it on my device. This reversed the polarity and now it works with no issues. Caple length is the right size and seems very durable. Very simple to use and zero issues. Getting 2 for this price is fantastic and saved me buying another adapter.
