Not really suitable for its intended purpose
Chris Q. 06.10.2022
Anytime I used this in a power bank, it would crash the output voltage. I had thought maybe something clever was done in the wiring of these - nope, they straight flipped the conductors.

It's a cheap way to convert a power supply, but if you run a fairly large board you just need an independent power supply.

It does what it says it does

It's a cable that inverts polarity. It works, what else can I write here? Every time I plug it in a stack of money magically appears out of thin air and for some reason I have gained 6-pack abs ever since I bought it. It's good I guess.

Good quality and works

Sadly for me there are opposite conventions in polarity between the guitar power supply 2.1mm connector and pretty much everything else in the known universe. The only multi-output power supplies are intended for guitarists, and sometimes "centre positive" devices fly in from outer space; in my (19") case, a Waldorf Blofeld, a GEM RP-X, and a Kenton Thru-5. All of these are powered perfectly well by these leads, and the fact that they are red reminds me of the extreme levels of stupidity that exist in the guitar fx multiverse and prevent me connecting something up with the wrong polarity, which would be so easily done.
