Cons

    Best Uses

    • Transform a transformer!

    Comments about Truetone Reverse Polarity Converter for 1 SPOT:

    I needed another transformer to run an effects pedal. Got a 9 volt "wall wart" at the thrift store really cheap but it was the opposite polarity. Found this cable for next to nothin' and it reversed the polarity without any issues. Now I have a four buck transformer rather than the fourteen buck original equipment unit. Be aware that some transformers will cause an audible 'hummm' thru sound equipment but this particular one did not. This cable is a good thing to have around!

        This is perfect for all the extra wall warts that you get with other equipment, such as cellphones, rechargeable drills, etc, that uses center positive polarity. Just be sure the voltage matches up with your device and your in.

          Comments about Truetone Reverse Polarity Converter for 1 SPOT:

          You can change the polarity of a positive center DC supply to a negative center one, and vice versa. That is what I bought it for, and it does what it is supposed to do.

              Comments about Truetone Reverse Polarity Converter for 1 SPOT:

              This product worked as they said it would. More people should be educated about the center positive and center negative connection on their adapters and devices. I think poor reviews are most likely caused by people not understanding this concept. If you sale adapters, the adapters should be listed in the description if the adapter is center positive or center negative. Customers buy an adapter and it does not work because it is the wrong center polarity, they get frustrated, and boom, take it out on a review. Your company would be on the leading edge with a little education to people who do not understand this polarity concept. Just my thoughts. Good job and good luck.

                  It is what it is. For some reason, pedals seem to use a center negative power supply connector whereas most household electronics are center positive. This lets you use a spare household power supply to power a pedal.

                            Bought so I could power my Korg Volca's with my OneSpot. This polarity inverter combined with a 2.1mm to 1.7mm adapter did the trick.

                              I like to keep an eye out for 9v DC power adapters at goodwill, etc for a buck or two, and can usually find one with a decent amperage but they are almost always backwards, polarity-wise.. with some pedals it doesn't matter but I like to play it safe when it comes to power, and these do the trick to reverse it.
