desktop speakers lacking power

[kcihtred2]

so I bought a muse 50, and it came without power cord (didn't read full description but whatever). went looking for power cord, only thing I can find is this

it has a light on it, refuses to do anything.  tried different cables with the brick. nothing.  and TBH the thing is kinda flimsy.  I cannot find anything compatible with it.  suggestions?
