## Description

Review: Great solution for odd pedals - 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 is great but it's unfortunate that we need it! - 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!
