Morning. I'm building a small portable music set up comprising of a Bastl Kastle, Bastl Drum, a couple of Pocket Operators with the VMX-10 as the mixer (maybe a effects pedal or two as well). I'm wanting to power everything independently from the mains supply. So, I was wondering if anyone had been able to power their VMX-10 with a power bank and usb adaptor such as the ones from MyVolts. Any help or advice would be very much appreciated.
