The missing like to power guitar pedals
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.

Perfect!
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!

ottimo cavo
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

Simple fix to adapt 9V guitar pedal power supply for use with positive center pin device
Used this to adapt a standard guitar pedal power supply to work with a KAT drum pad that has a positive center pin connection. Simple and inexpensive fix to replace old PS that died. Easier and cleaner than rewiring the pedal supply connector.
