I got a neighbor who has an outdoor Christmas decoration. It's 20 years old and the power supply went bad. So we bought a new one that was said to be compatible. The specs were the same, but the connections were different. I'm wondering if there is a way via an adapter/converter to attach or other means to make this all work.

Sure that tiny thing can handle 5A?

Haven't a clue, but the power supply's specs are the same, the only different is the plug. I was hoping there was something simple I could buy.
 
With a screw terminal (10 c), a knife (0 c), a screwdriver (0 c) and duct tape (1 $) you probably can't get cheaper and simpler. I wonder if that Chinese plug fits into anything else as his mother socket. My first thought was "no prob, in Europe we have to deal with adapters all the time". But then I saw your coaxial RCA and the first time with so much current. Even on amazon I couldn't find a quick solution.
 
So from the pictures, you still have the old power supply's male plug? You can buy the male mate to your new power suppliy's coaxial barrel plug, and solder it onto the wires from your old power supply cable (cut the cord, strip and solder). It looks like the old 2-prong plug does not have polarity, right? Or does it only plug into the fixture one way?
