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.

Just the job.
I sometimes film football matches, no problem when there is mains power but if not then I have to use the camera batteries. I also use a 9" monitor that comes with an in built battery that unfortunately never lasts the full 90 minutes or more.I recently found in my video gear a separate back up battery for an old monitor that was the right voltage so I tried it with my 9" monitor but it just didn't work, I knew it was charged up so just thought for some reason it was not compatible.I then thought perhaps the plug was the wrong polarity so I bought these thinking they probably wouldn't work and bingo the one the correct size did.Wish I had known about these before, absolutely 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

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!

Work great for the Sega Genesis model1 console!
It work great with my Sega Genesis model 1!Most high quality 9V 1.5A power supplies have center-positive polarity, and the Sega Genesis model 1 console (which need 9V 1.2A minimum) need center-negative polarity. So this cable is pefect for this!
