9 volt to 5 volt micro usb converter in Relay Digital Wireless Posted July 9, 2018 I just got a 1Spot Truetone CS-7 which has 7 isolated outputs. One is 12v 100mah. I had been powering my G10 with a Lipo power bank but figured I'd try using that 12v output none of my pedals use. I bought a simple 5.2 - 24v step down to 5v board on Amazon. Has a regular female 9v DC socket one side and a USB Type A the other. The Power supply came with a reverse polarity cable in the extras. If you don't have one, you probably need one to get the right polarity for the micro USB, you you can get those separately for less than $10 here. Worked a treat. If you have any spare outputs up to 24v this does a good job.
