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.

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!

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. Brilliant!

Esegue perfettamente la sua funzione, abbastanza robusto e preciso nella connessione senza giochi. Indispensabvile per l'alimentazione di pedalini per chitarra elettrica e multi effetti senza alimentatore proprio. Consigliato
