myVolts have been making powerbank and USB power solutions for a while now. Who hasn't got the Ripcord USB to DC power? I know we have. They also make a bunch of useful audio innovations too; Candycords cables or the TAPS audio flow widgets.
We feel like we've been on the journey with them, so it was really lovely to finally meet some of the team, this was their first Synthfest.
Check out their stuff at myVolts.co.uk
