thanks for the answer kevin, but that site says obsolete item and its in america so an american plug doesnt help me thanks anyway, im sure some sort of adaptor must exist for my current plug, so far ive had no issues but im getting a new midi keyboard soon that doesnt come with a power option, usb only, if i have to many things running usb they might start not working properly, im sure if the spark was powered by a plug ill have less issues and the way i see it if a product has an option for a power plug it should be really easy to get a psu for it if isnt supplied with the unit!!!! imagine if when you got a mobile your only option was to use a usb lead with pc that would be annoying, even though i love my spark i do regret buying it therefore there is no way i will get a keylab as a 49 keyboard sorry if this is a bit negative but its not asking much to have a psu that is either provided with the unit or if not it can use a psu that can be easily purchased
