This Korg Volca Power Supply is a 9V, 600mA power adapter for the Korg Volca Series synthesizer modules. Instead of wasting batteries when you're making music in your studio, get the Korg Volca Power Supply!
So lol at all the people saying you will be spending a lot of money on batteries for the Volcas - you get like 10 hours or so out of them. Also I have noticed that with the Keys, at least, when the battery power gets around 25% it starts doing strange and beautiful things that would be excellent to get certain sounds from. However - I own all four Volcas and yes that does get expensive - especially when you use all four at once like all day every day (lol) so yes -..
