## Overview

The Belker 5.5 x 2.1mm Jack Reverse Polarity Converter Cable is a must-have for musicians and tech pros needing to switch polarity on DC power connections.

## Description

Designed exclusively for Belker Universal Multi-Voltage AC Power Adapter, Also for most adapters with 5.5*2.1mm output plug tip. If your device polarity is contrary to the adapter, please use this cable to convert. Generally applicable to baby monitor, keyboard, speaker, radio, electrical toys, and more small ac electronics with central negative polarity -.

Review: I use this for a vintage DOD chorus pedal. Works perfectly what can I say? Without this I’ve would have been unable to use it.
Review: This reverses the polarity of any 5.5x2.1mm round-tip power cable. It is a necessity if you also purchase the Belker Universal 5V DC Power Cable USB set since that is only tip-positive. Using this adapter cable along with that universal set allows it to work with tip-negative devices. I am grateful that this is available! I'm disgusted by the electronics industry that it's necessary! The industry should abandon all USB-A to Round-Tip power cables. We all have hundreds of USB-A to microUSB or miniUSB cables lying around so that if one cable breaks or gets lost it's no big deal. But since the industry refuses to standardize on anything other than having a USB-A connector on one end of their cables, this Belker Polarity Reversing Cable is great to have on hand!
