Evening planet earth

I am going to be getting the Boss ME-25, I have found it online for £137, but it is an extra £20something for the powersupply?!? I have a spare daisy chain power supply lying around that works powering me Boss DS-2 and i was wondering if it would also work for the ME-25, with it being a much large multieffects pedal?

If it makes any difference it would be the only pedal powered by the daisy chain and all of my other pedals are already hooked up on one?

Hope this is clear
