I've got a pedalboard and I've used all of the 9V sockets on my power supply but have a couple of spare 12V DC ones.
Are there any 12V DC to 9V DC converters about so I could use those power outputs?
I've also got a USB powered component - are there any 9V or 12V to USB converters about?
Also a supplementary question... are they good, stable, reliable?
