SUMMARY

The discussion centers on finding an adapter to connect a new power supply to an old outdoor Christmas decoration. The old power supply's specifications match the new one, but the plugs differ. Participants suggest using a male mate to the new power supply's coaxial barrel plug, which can be soldered onto the old power supply cable. A specific adapter from BatterySpace is recommended as a potential solution, priced under six dollars.

PREREQUISITES
  • Understanding of coaxial barrel plugs and their specifications
  • Basic soldering skills for electrical connections
  • Knowledge of electrical current ratings, specifically 5A
  • Familiarity with using tools like screw terminals and duct tape for DIY repairs
NEXT STEPS
  • Research how to solder coaxial barrel plugs effectively
  • Learn about electrical current ratings and safety precautions
  • Explore various types of power supply adapters available online
  • Investigate DIY solutions for connecting incompatible electrical plugs
USEFUL FOR

DIY enthusiasts, electrical hobbyists, and anyone looking to repair or adapt outdoor electrical decorations.

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? If you don't have to change current and voltage, there's always the old fashioned way.

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?

maybe something like this?
Certainly looks like a match visually!
 
You could measure what you have and compare. Less than six bucks.
